With a two-deck prescreen, rotor and the optional afterscreen, the Keestrack R6 effectively puts three machines into one mobile spread.

The prescreen scalps material before it reaches the crusher. From there, crushed concrete moves through the afterscreen for final sizing before being sent out to the stockpiles.

It gives the operator the functions of a scalping screen, impact crusher and classifying screen without adding separate machines to the spread.

If you're in the custom crushing business, you know the inconveniences of moving heavy machinery around.

Sometimes the machine spends more time moving than it does crushing. Whether it's limited access in and out of a site, piles at different locations or a contract that only runs a few weeks, a static or chassis plant isn't always worth the trouble.

The QJ241 was made for these situations, being the most compact machine in Sandvik's QJ series. At 36.9 tons (33.5 tonnes), it's easy to float and to move around on site.

Being smaller doesn't cost you much on output. It takes feed up to 21” (520 mm) through a 40” x 26” (1,000 x 650 mm) opening, with a 225 hp (168 kW) engine behind it and capacity up to 248 tph (225 mtph).

Pair it with a QH441 cone and now you've got a spread that takes a 21” rock down to ~5/16”.

Conveyors come in all shapes and sizes, from custom-built fixed assemblies to mobile, tracked units.

Across a material processing site, they can be used to move material between machines, transfer it to different areas, feed another conveyor, or build stockpiles while reducing loader handling.

We offer two main conveyor types: stacking conveyors and feeder stackers.

One of the first questions we ask when pairing a customer with the right machine is how the conveyor will be loaded.

If material is coming in at a constant rate from a crusher, screener, grinder, or another conveyor, a stacking conveyor is typically the better fit. It is designed to handle that steady flow and keep material moving through the operation.

If the conveyor is being loaded in batches with a wheel loader or excavator, we generally recommend a feeder stacker. The hopper provides a larger loading area and helps regulate material onto the belt. For loader-fed applications, a low-level feeder can make loading even easier by reducing the height the operator has to reach.

The machines can look similar, but the way material enters the conveyor plays a major role in choosing the right setup for the job.

The Keestrack R6 putting in serious work into recycling concrete and asphalt.

08/20/2026

Back in 2022, West Corridor Constructors had to fit a full crushing operation into a hundred-foot-wide corridor on Highway 401, with traffic moving around it the entire time.

Rather than truck material out to a yard and back, they brought the crushers to the material.

Multiple Keestrack R6 impact crushers ran across 18 km of reconstruction through Mississauga and Milton, getting picked up and repositioned every 30 to 45 minutes as crews worked down the windrow.

The crushing phase wrapped that July, with roughly 800,000 tons of old concrete road and asphalt RAP reused on site.

Fuel is one of the biggest costs in making cement. Coal and gas prices move with the market, and leaning on them alone leaves operators exposed every time prices spike.

That's why many plants run processed engineered fuel (PEF) and other alternative fuels as a partial replacement. In European markets, an average of 52% of the kiln's heat is created this way.

C&D waste is a strong starting point for PEF, though it comes with challenges. Sizing has to be accurate, and metal has to come out of the pile.

That's what this CBI 5900T was on site to do. Screens set the output size, and the optional overband magnet can lift unwanted metals off the discharge belt as the processed material runs underneath.

Did you know?

Every machine we deliver, new or used, undergoes a complete inspection before it reaches your site.

Our service technicians carry out any repairs required and configure the machine to your operation's specifications, so it's ready to produce the day it's offloaded.

Dust shows up on almost any dry jobsite, whether you're crushing, grinding, screening, shredding, or just moving material around the yard.

A bit of dust on its own isn't really an issue. Let it build up and it starts limiting what your operators can see, increasing safety risk with people working around loaders and trucks. At its worst, dust brings the whole site to a stop while complaints and air-quality rules get sorted out, and you're looking at hours or days of lost production.

SprayStream dust cannons keep that from happening. A fan drives a cloud of atomized mist over the work area, and the fine droplets bind to the airborne dust and pull it to the ground before it spreads.

Your crew can see what they're working around and isn't breathing it in all day. It runs on its own while the crew keeps working, so dust is no longer an issue.

Setting up a stacker eats into the day before it processes a single tonne.

The Keestrack S5 folds its main conveyor down hydraulically for transport, then unfolds and sets into one of three fixed inclinations once it's on site. Packed down, it measures 12 m x 2.2 m x 2.8 m and travels to site as a single tracked unit.

Once on site, the tracks handle repositioning between stockpiles. Operators either walk alongside the S5 with the standard wired remote, or control it remotely with the optional radio remote.

Idle time on a screener still costs you diesel, even when the machine has nothing to do.

The C6 uses load-sensing hydraulics, so power only goes where the machine actually needs it instead of running everything at full pressure the whole time. Keestrack rates that at 20 to 30% lower fuel use than a standard diesel screen plant.

In diesel-hydraulic mode the C6 burns around 14 litres an hour. Diesel-electric drops that to ~9. Plug it into another machine's power unit and it's down to ~4 litres an hour, or wire it straight to mains power and run on 36 kWh with no diesel at all.

If you're running one of these behind a crusher for a full shift, that difference shows up on the fuel bill fast.
