Out of all construction materials, concrete stands out as the most responsible for advances in construction and architectural designs. Without concrete, we would not see any urban development, highways being built, dams created, military installations, and a whole host of other vital elements of modern society. Here comes the role of concrete crusher machines.
These machines are known for their high durability, any concrete construction still has a limited life span. Because of this, the very thing that makes concrete so valuable, is also what makes it a challenge to either recycle, or dispose of. Due to this escalating need for concrete, we have developed a dependence on the concrete crusher.
The concrete crusher’s job is to break down large blocks of concrete waste into smaller pieces that can be disposed of, or recycled in a more efficient manner. What follows is a general explanation of different types of concrete crusher in the industry today.
Various stages of crushing:
Concrete crushing is achieved via a series of stages. The first stage breaks large concrete blocks into smaller, more manageable pieces.
A jaw crusher is typically used at this stage of the demolition. With a reduction ratio of 3/1 to 5/1, these machines are proficient of taking concrete blocks of all sizes. Crushing the concrete using the machines look similar to the process of chewing. So, jaw crushers employ a fairly straightforward design.
Cone crushers involve a tapering, concave area that has a rotating spindle that gyrates as it turns. Concrete is dropped in at the top of the machine which is crushed into smaller and smaller piece as it moves further down into smaller gaps. Eventually, pieces become small enough to fall through the chute and into a hopper. Cone crushers can be large in size, but there are also smaller, portable variations which can be moved between sites.
Impact crushers work by making use of a striking force rather than pressure. There are two main variations of impact crushers; horizontal and vertical shaft impactors. A horizontal impact crusher holds the concrete in a metal container. Hammers fixed to a spinning rotor pound the concrete until it breaks down into suitable sized pieces that can be pushed out of gaps in the side of the machine. More suitable for softer substances, they still have a reduction ratio of 25/1.
Due to the constantly increasing use of concrete in the building industry, we can safely assume that the concrete crusher machines will continue to be a useful tool for some time to come.
We may see alternative development methods and materials being used, but for large scale buildings, concrete has yet to see a viable substitute. So the concrete crusher will probably be around for a long time to come.
