A Decade Of Use At The Sechelt Gravel Mine

When choosing aggregate equipment, durability is a must. You want your investment to pay off, and every time your equipment goes down, your operation is leaving money on the table—not to mention the cost of expensive parts that need to be replaced.

We build our aggregate equipment to be robust and simple, increasing time between maintenance outages to lower operating costs. This isn’t just a statement; our equipment has proven results. Sepro’s Tyre Drive Scrubber installed at the Sechelt Sand & Gravel Mine has been running issue-free for over a decade.

The Sechelt Sand & Gravel Mine

One of Canada’s largest aggregate operations, the Lehigh Hanson Materials Limited’s Sechelt mine covers over 250 hectares of land and produces 4 million tonnes of aggregate per year. The mine produces five types of product, namely crushed stone, gravel, recycled construction aggregate, sand, and concrete aggregate.

The mine has been using a Sepro Tyre Drive Scrubber for over ten years with no issues or interruptions to their operation.

Applications Of The Tyre Drive Scrubber

At the Sechelt Sand & Gravel Mine, the scrubber removes clay contamination from crushed aggregate, gravel, and sand to produce a clean product. Other scrubbing applications for our Tyre Drive Scrubber include:

  • Removal of clay from hard rock ores before crushing
  • Cleaning of contaminated soil and rubble
  • Washing of sticky clays to enable effective screening
  • Pre-treatment of mineral ores in the metal mining industry

Built-In Durability

The Tyre Drive Scrubber features a rugged and durable design to make it one of the most reliable scrubbers on the market. We’ve replaced critical components like ring gears, chain drives, and steel wheels with a more reliable Pneumatic Tyre Drive System. This system of rubber tyres mounted on independent gearboxes provides excellent serviceability and reliability.

By using standard major components, downtime is minimized as replacement parts are widely available. The heavy-duty truck tyres can also be sourced locally. You’ll never be without the parts you need to keep it running.

Expertly engineered, durably built, and field proven, the Sepro Tyre Drive Mineral Scrubber can tackle the toughest mineral scrubbing project day in and day out. For more information about mineral scrubbers or aggregate equipment, contact the experts at Carminex today.

Concrete 101

Concrete and aggregates were made for each other — aggregates are the most mined resource in the world and concrete is the most frequently used man-made material! It makes perfect sense that aggregates make up over half of a concrete mixture, but what else goes into making concrete? What kind of aggregate equipment is used in its production? Are cement and concrete the same thing? Let’s find out.

Cement vs. Concrete

People often use the terms cement and concrete interchangeably. In fact, cement is a key ingredient used to make concrete. Cement is a binder that tightly holds materials together. On its own, cement is not very strong. But, when cement is mixed with water, sand, gravel, and other aggregates, a strong material known as concrete is created.

More about Cement

There are two forms of cement: hydraulic and non-hydraulic. Hydraulic cement uses water to initiate a chemical reaction that hardens the mixture. The properties of hydraulic cement allow the mixture to harden in wet conditions, even under water. When the mixture has set, the product is hard, durable, and fully water resistant. Almost all cement used today is hydraulic.

Non-hydraulic cement uses materials that cannot harden when exposed to water and cannot set in wet conditions. It needs a completely dry environment to harden. Non-hydraulic cement is cheaper but because it takes a long time to dry and won’t harden in wet environments, it’s a poor choice for most construction sites.

What About Concrete?

Concrete is a mixture of cement, water and aggregates. Aggregates make up between 60 and 75 percent of the mix; cement and water make up the rest. The aggregate used can include sand, gravel, crushed stone, or recycled concrete. Different aggregates will be selected, depending on the application of the concrete.

To grind and crush stone into aggregate, heavy-duty machines like cone crushers and jaw crushers are used. The crushed aggregate is then screened for sizing before being added into the concrete mixture.

Concrete starts out as a semi-liquid and has excellent weatherproof properties. Because it’s incredibly strong, it’s ideal for use in construction and home DIY applications. Concrete is also fire resistant, durable, requires little maintenance, is environmentally friendly and energy efficient. These properties make concrete the most widely used man-made material on earth.

How Is Concrete Recycled

Most new city construction projects begin with the demolition of old sidewalks, buildings, or concrete structures. The demolished concrete is then broken down on site with a portable plant. After that, it’s screened, sorted by size and prepared for use as recycled aggregate.

Recycled aggregate can be used in landscaping, as a foundation for new roads, or even to make new concrete. This recycling process reduces the need to mine new materials and removes the environmental impact of transporting aggregate from a mine to a work site.

Carminex has decades of experience mounting aggregate equipment to portable plants. To get started on a portable solution for a concrete recycling project or any mobile crushing project, call us at 1.450.922.0900.

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.

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.
To speak with an aggregate expert about your next portable plant, contact us at 1.450.922.0900.

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.
