Industrial and commercial demolitions contain hundreds of tons of concrete. Instead of throwing all this material away, it can be crushed for use in a number of projects.
Types of Concrete Crushers
This crusher works exactly like a nutcracker. The debris is crushed between two vertically oriented jaws that are tapered to only allow the small material to pass through. The jaws are powered by a flywheel that opens and closes just like a mouth. Jaw crushers are used for their ability to process abrasive material and low maintenance costs.
Instead of using pressure to break the concrete like a jaw crusher, an impact crusher relies on impact. Some throw the rock against a hard surface so hard that it disintegrates. Others use a hammer on the outer edge of a spinning rotor to break the rock apart. Contractors use impact crashers due to their effective severance of rebar and wire mesh and easy replacement of parts.
As the name suggests, they are shaped as a cone where the open base accepts rock. As the demolition materials go down the tip of the cone, they are crushed between two layers, one that is mobile and another one that is fixed. Even though they are less common, cone crushers require low operation costs, they are easy to adjust, and they offer high productivity and offer hardy construction.
Demolition contractors review the following qualities when choosing a new crusher:
Feed material: does the machine process any other type of material, not just concrete?
The rate of production: each crusher has its own production rate, usually described in tons of material processed per hour.
Size of the equipment: the dimensions of the machine determine transportation and storage options.
Environmental considerations: state or city regulations dictate how much dust a demolition site can create. Different crushers produce different amounts of dust – the jaw crusher produces the least dust.
Output size: the size of the crushed product determines how the material is going to be used. Parking lots and roadways have their own size requirement. To achieve smaller materials, a series of crushers are usually needed.
Moisture content: jaw crushers cannot work on wet materials but cone crushers can as long as the material isn’t sticky.
Emergency shut-off: the crusher should have a hydraulic toggle retaining device for turning off the device before damaging materials cause harm.
