Out of all the construction materials known to man, one in particular stands out as the most responsible for advances in architectural design and construction: concrete. 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. Despite being valuable for its 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 Concrete Contractors San Antonio 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.

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 capable of taking concrete blocks of all sizes. The operation of crushing the concrete looks very similar to the process of chewing, so jaw crushers employ a fairly straightforward design. A tapered chute is formed with two reinforced metal plates. One of the plates is fixed in position, while the other slides backwards and forwards. As the concrete moves through the chute, it is crushed into smaller and smaller rocks, until the pieces are finally small enough to fall through.

The concrete will either be reused in this form or it may be crushed down further, depending on what the planned use of the concrete is. Frequently, the use of a secondary concrete crusher is employed, the most common two being cone crushers and impact crushers. Each one is named after the mechanical method used to break the concrete down.

Cone crushers involve a tapering, concave area that has a rotating spindle that gyrates as it turns. Concreted 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, like jaw crushers, also have a 3/1 to 51/ reduction ratio. 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.

A vertical shaft concrete crusher makes use of velocity rather than surface force. A high speed rotor throws concrete blocks against a hard internal surface, shattering it. The size of the end product is determined by the rotor speed, and the distance thrown. The harder the concrete hits the containing wall, or anvil, the smaller the pieces will end up being. Recycled concrete using this process has many useful applications, due to the quadratic shape of the end product. A typical vertical shaft concrete crusher can achieve a reduction ratio of 8/1.

Due to the constantly increasing use of concrete in the building industry, we can safely assume that the concrete crusher 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.
