What Happens To Pits and Quarries After Use?

Pits and quarries are necessary for the infrastructure of our societies. Roads, buildings, bridges, and homes are all reliant on the aggregates mined from these operations. What most people don’t realize is that quarries are temporary enterprises that are eventually rehabilitated to a natural state. You might even live near an exhausted quarry and not know it, and that’s the point. When all the aggregate equipment moves on to their next project, the land is repurposed for the benefit of our societies.

Planning A Quarry

Many countries and governments have strict guidelines when it comes to planning a new quarry. For example, to get a license for aggregate mining in Ontario, a site plan (that includes a rehabilitation strategy) must be approved before any digging takes place. Rehabilitating a pit or quarry is the process of restoring the land to its original state or different planned end use.

Quarries are almost always located near populated areas. The greater the distance between the final end user of an aggregate product and the source quarry, the greater a project’s economic, environmental, and social costs. Increasing distances means burning more fossil fuels and increased wear and tear on roadways.

What Are Quarries Turned Into?

Once the aggregate equipment has packed up, the quarry is ready for rehabilitation. Pits and quarries can be turned into wetlands, wildlife habitats, golf courses, parks, conservation lands, housing developments, forests, and even farms. Take a look at these two pictures and try to figure out which one used to be a quarry.

Could you figure it out? Well, they both used to be quarries. Picture #1 is Royal Botanical Gardens in Burlington, Ontario and picture #2 is Queen Elizabeth Park in Vancouver. There is very little chance that anyone would recognize that these sites were once quarries where sand, stone, and gravel were harvested.

These are just two examples of successful rehabilitation programs in Canada, but these restorations take place globally as well.
The worksites that provide us with the building blocks of our society can often be turned into something even more beneficial when production has ceased. Carminex is proud to supply aggregate equipment to responsible quarry projects all over the globe.

A Familiar Face Joins Our Aggregates Team

To provide the most comprehensive solutions for our customers, we take pride in pairing superb aggregate equipment with experienced staff members. Recently, our team has grown to include a familiar face. Dave Phelan has joined our ranks as a Product Support Manager. Dave’s 40 years of experience working with aggregates, crushers, feeders, and all things construction will be put to use providing innovative solutions for our customers.

We recently took some time to get to know Dave a little better. Here’s what he has to say about his experiences, Sepro and Carminex, and where the industry is heading.

Hello Dave! Could you briefly introduce yourself to the people that don’t know you yet?

I grew up on a 200-acre beef farm in central Ontario with one brother and two sisters. I graduated high school from L.C.V.I. in Lindsay Ontario in 1978.

My family sold the farm for its gravel resources to Beamish Construction in 1978 where I worked for over three years. I started working for a division of Beamish called Royel Paving Ltd. crushing aggregate for their asphalt plant. This was seasonal work and each winter I went to Alberta to work for a drilling company.

In 1980 I got married and am still married 39 years later to the same great lady. We have one son who is now a teacher in Ontario with two great little sons of his own. In 1981 I decided to go to college and graduated S.S.F.C. in Lindsay with a two-year Heavy Equipment Diploma.

Since graduating, I’ve worked in a range of industries from recycling construction materials, servicing aggregate equipment, product development, sales, and more.

How did you get your start in the aggregates industry?

During and after college I worked for D. Crupi and Sons Paving in Agincourt where I operated a wide range of equipment from road planers to asphalt plants. There I became an asphalt plant foreman and then the Recycle Crushing Supervisor in charge of operations and maintenance.

I worked for Lippmann- Milwaukee Inc. for 12 years as their Canadian Sales Manager and with their Engineering department. During my time at Lippmann, I designed many new pieces of equipment, apron feeders, HSI Impactors, feeders and jaw crushers as well as many improvements to existing aggregate equipment.

Why did you decide to join the Sepro team?

I joined the Sepro team to help accomplish the same goals I had done previously with Lippmann. During my crushing career, I had operated and maintained several crushers built by the predecessors of Sepro and know this equipment and the history behind it. I thought I could be of assistance to their current operations.

What makes Sepro different from the other companies you have worked with?

Sepro has built an existing team of great people. It’s also built on a platform of serving and working with its customers to better a product and help the customer improve their operations.

What is your official job title and what are your primary responsibilities?

I have been hired as the Product Support Manager to help the sales and engineering teams better promote Sepro’s products and customer possibilities.

What do you find most appealing about the work you’re currently doing?

I love talking with customers and designing equipment suited to their requirements. Each customer is different as no one application is the same.

What are some of the challenges you foresee in the aggregate/mining industry? Do any possible solutions come to mind?

I think climate change is going to be the most significant factor in the future and things like shoreline restructuring are going to become a major factor in the industry. Designing improved ways of handling and processing material is a driving force behind why I stay in this industry.

Do you have a favourite piece of equipment? What is it and why?

To say whether I like one industry or type of equipment over the other does not even come to mind. I’ve done concrete, asphalt, wood, tire, recycling as well as virgin aggregates and mining. All have their place, and it is amazing to see the similarities between the operations and people.

One thing I have found about these industries, is that 98% of the people that work in them are not about themselves, but take pride in their operations and fellow employees. I have great respect for the men and women working in our industry, and it takes a lot to persevere through the different work and environmental conditions.

In your free time, what do you enjoy doing?

When the day is over we all need some form of release and, depending on what you do or where you are or what your life is about, that can vary.

In the summer I golf as much as I can. In the fall I love to hunt, and in the winter it’s snowmobiling. I make sure to complete everything on my to-do lists before diving into these activities.

Thanks for your time, Dave!

If you have any questions for Dave or our other experienced staff about aggregate equipment or parts, feel free to give us a call at 1.450.922.0900. Our team is excited to help your current or future project reach its target goals.

The Benefits Of A Grizzly-King Jaw Crusher

Grizzly King Jaw Crusher

Jaw crushers were first introduced to the world by Eli Whitney Blake in 1857. His invention was so unique and practical that it earned him a place in the National Inventors Hall Of Fame. Simple and strong, the Blake Jaw Crusher is still the standard to which modern-day crushers are compared.

Now let’s fast forward 160 years.
Introducing the Grizzly-King Heavy Duty Jaw Crusher. This robust piece of machinery was engineered to outperform and outlast all other crushers. We’ve taken Blake’s original idea and heavily invested in research and development to create the king of crushers. Meeting your production goals has never been simpler.

Jaw crusher

Built To Produce

Our jaws are longer than those of conventional crushers, giving the Grizzly-King a few distinct characteristics. Longer jaws increase the size of the crushing chamber, allowing more material to be processed per stroke. It also allows for a narrower nip angle, providing a more positive bite and reducing the possibility of ejected material. Fewer pinched out rocks makes the machine safer for operators.

An eccentric jaw motion forces material through the crushing chamber, and increases production while maintaining the same discharge opening size. The Grizzly-King can process over 950 tons per hour.

Built To Last

The massive frame construction built with heavy steel sections will keep your Grizzly-King in service for years. Its superior rigidity maintains bearing and shaft alignment and prevents costly failures. With a consistent discharge size, you will be able to reduce recirculation, and decrease the wear and tear on other equipment in your production line.

Applications For Your Jaw Crusher

The Grizzly-King can be used as a primary crusher in mining, pit and quarry, construction aggregates, and demolition recycling. Carminex can mount your Grizzly-King Jaw Crusher on a portable plant, allowing your crushing operation to become mobile. This can save time and money when you need to move between sites.

The dimensions for our Grizzly-King Heavy Duty Jaw Crusher are as follows:

How Aggregates Help Build Our Cities

City view

Sand, stone, and gravel produced by the aggregate industry are the building blocks of our modern world. Every structure from the homes we live in, the roads we drive on, and the buildings we work at are all made possible because of aggregates. In fact, it takes 400 tons of aggregate to build a typical home!

Our goal at Carminex is to supply the most efficient mining equipment to, quite literally, support the foundations of our cities. Having over 25 years of supplying aggregate equipment and parts to the industry, Carminex has the expert knowledge necessary to help you through the buying process. After all, it is essential that you use the right aggregate equipment that best fit your project requirements.

Aggregates For Concrete

Concrete is made up of 60%-80% aggregate. Quality concrete comes from clean, hard, and strong aggregates that are free from chemicals or clay coatings. After harvesting, the aggregate used in concrete needs to be crushed, screened and washed. Poor screening could result in fine materials making their way into the concrete mixture which could cause deterioration of the concrete after it has set.

The right particle shape and size also matter when it comes to creating quality concrete. Rough textured, angular and oddly shaped aggregate require more water to produce a useable concrete. Completely flat and elongated pieces are avoided or are limited by weight percentage. With the proper aggregate equipment, you can be sure that you are delivering a high-grade, consistently shaped, and contaminate free aggregate.

Aggregates For Road Construction

Roads built with a weak foundation will fail prematurely and require more maintenance. Having a strong foundation starts with having a contaminate free aggregate.

Recycled concrete makes an excellent foundation for building roads. Collected from construction sites with the help of portable plants, it is filtered to remove any debris, metal, or contaminants, and crushed to a consistent size. Using recycled aggregate keeps it out of landfills, is cheaper than harvesting and processing new materials, and is environmentally friendly.

After a foundation is appropriately laid, asphalt is paved on top. Asphalt is made from 95% aggregate material and 5% bitumen.

Whether you realize it or not, aggregates have shaped the world. It keeps our buildings standing tall against the elements and our roads from failing beneath us, and it all starts with the right aggregate equipment. To find out what piece of equipment will fit your next project perfectly, contact the aggregate equipment experts from Carminex.

Recycle Your Aggregate Onsite With A Portable Plant

Having a portable plant built to recycle concrete and asphalt aggregates is becoming more common as industry standards on energy consumption tighten. It’s also more cost-effective to crush concrete and asphalt on-site versus loading and hauling the resources from your construction area or quarry. At Carminex, we have the experience necessary to mount any portable impactor to a custom built plant for effective mobile aggregate recycling.

Lower Your Energy Consumption

The days of trucking used concrete to landfills are over. Recycling concrete for future projects is now the norm. Instead of loading and hauling your aggregate away to a recycling centre, which increases fuel consumption and pollution levels, we can create an electric, portable impactor plant. This system reduces emissions and operational costs, while creating a reusable concrete or asphalt aggregate.

Difficulties In Recycling Aggregate

Recycling concrete or asphalt can only be achieved if all of the impurities are removed. There cannot be any metal or steel such as rebar left in the feed. Our plants are built with powerful filtering magnets onboard, to rid the construction material of contaminants before crushing. If large metal pieces find their way into the impactor, it could become damaged. Carminex’s portable impactor plants make sure this doesn’t happen.

Finding parts for your mobile plant can also be a challenge should a piece of equipment onboard need maintenance. Carminex has Hewitt Robins™ parts and equipment for our portable plants in stock to limit any equipment downtime that may occur.

Sorting your recycled concrete or asphalt after processing is another difficulty posed to portable plants. With Carminex, you won’t need to purchase any other extra conveyors or screens; we build them right into your mobile plant. It’s an all-in-one mobile solution.

Creating Your Portable Solution

We’ve been building mobile solutions for aggregate companies for decades. We have the parts, equipment, and experience necessary to build you a safe and functional piece of equipment. Our portable plants can use Sepro, OEM, or any customer-supplied screening or crushing equipment. They are easy to maintain, quick to setup and teardown, making frequent moves between yards quick.

How Aggregate Equipment Improves Quebec’s Growing Mining Industry

Large Quarry

The right equipment can be the difference between hitting your targets and wasting time and resources. Carminex has been providing aggregate equipment solutions to mining and quarry operations around the world for over 25 years As the mining industry rises in Quebec, we are proud to be supplying more equipment closer to home.

Quebec’s Mineral Supply

Quebec is home to the most diversified natural resources in all of Canada, including 15 metals and 13 minerals. This includes rare metals such as lithium, gold, nickel, niobium, titanium dioxide, cobalt, and platinum. The province is also Canada’s biggest producer of zinc and iron concentrate and its second largest producer of gold.

Technology has driven the demand for lithium, nickel, and cobalt up as these are key metals in creating everything from phone batteries to electric vehicles. It is predicted that the number of electric vehicles on the road will hit 130 million globally by the year 2030 – a massive increase from 3.7 million in 2017. Since the essential metals to our current technological needs can all be found in Quebec, it’s easy to see why the province is becoming a popular spot to set up new mining operations.
Quebec is also responsible for one-third of Canada’s annual aggregate production including limestone, granite, sandstone and marble. The crushed stone is mainly used by the construction industry for asphalt and concrete aggregate.

Government Incentives

Quebec’s government is very open to mining exploration. Currently, only 5% of the province’s vast area has exploration rights assigned, leaving great opportunities for finding new deposits.

There are a number of tax incentives for companies that engage in mining exploration as well, creating a welcoming environment for new mining operations. The combined tax rate for corporations is 26.8%, one of the lowest in North America.

Get The Most Out Of Your Mine

A study from the Fraser Institute found that Quebec is ranked 6th worldwide when it comes to mining attractiveness and it’s easy to see why. Valuable mineral deposits, a favourable business environment, and quality aggregate equipment suppliers can all be found in the province. For the best mining solutions, contact an aggregate expert at Carminex today or call 1.450.922.0900.

What’s The Difference Between A Jaw Crusher And Cone Crusher?

Crushing equipment has the seemingly simple job of breaking up massive boulders and rocks into smaller aggregate. Something so straightforward is quite complex in practicality. Huge machines weighing thousands of kilograms, crush some of the hardest materials ever to exist, pumping out tonne after tonne of valuable stone.

The two most popular pieces of aggregate equipment in the market include cone crushers and jaw crushers. While cone crushers and jaw crushers both perform a similar job of breaking rocks, their approach and applications are quite different.

Introducing The Jaw Crusher

These burly machines act as a primary crusher for mining and processing ore. Two powerful jaws (one fixed, one moveable) are mounted in a “V” alignment. The moveable jaw reciprocates, crushing the large rocks until they are small enough to fit through the opening at the bottom of the “V.” The Grizzly King Jaw Crusher is one example of an effective aggregate solution.

Jaw Crusher Benefits

Every site has different needs and requirements, so jaw crushers can be found in different sizes and capacities. This gives you the opportunity to make the most optimal choice for your project. If you are not sure what size fits your current needs, speak to one of our aggregate experts.

Parts are easy to find, and maintenance is straightforward. Carminex carries a full stock of jaw crusher parts to keep your machines up and running. Performing simple maintenance will ensure that your jaw crushers provide long-term value.

Introducing the Cone Crusher

Cone crushers take care of secondary and tertiary crushing applications. Fine and medium-sized aggregates (used in asphalt and concrete, for example) are created by an eccentrically rotating shaft that grinds the rocks between a robust metal cone and a fixed wall. The Blackhawk 100 Cone Crusher is an example of a powerful cone crushing machine.

Cone Crusher Benefits

Large feed openings can be paired with small discharge sizes, giving cone crushers a high crushing ratio. This makes the machines incredibly efficient, reducing the need for further crushing applications. Adding in the low operational costs to run the machine and you get a powerful tool with a small footprint.

Sepro Cone Crusher

Wear-resistant, durable parts give the machine a long life-span. Parts are readily available as well, limiting any equipment downtime.

Additional Crushing Benefits

Carminex can create a portable plant for both the jaw crusher and cone crusher for contractors and sites with multiple locations. Some of our current mobile crushing plants are being built in Montreal right now for delivery to Indonesia.

As Canada’s largest supplier of mineral processing equipment, we’ve been creating and delivering custom solutions for aggregate equipment, including jaw and cone crushers, for several decades now. We’ve provided technical and operational support on many projects, ensuring that each job is met with the proper solution.
