Concrete Crusher Machines: Yesterday and Today
The earliest versions of concrete and rock crushers involved the use of two rocks being slammed against each other. An anvil was formed by one rock, while the weight of the other was used through manual power to achieve the necessary crushing. A crusher that was called the Cornish stamp was developed in the 19th century for breaking up tin and was used in mining. The early years of the 20th century led to portable rock crushers being developed.
The design of such crushers were static for almost six decades. The cone crushers that then developed were of high speed and were very reliable. A cone crusher of 48 inches developed in the 1960's had a capacity to crush 170 tons of rock. The present development in technology has led to the same size of crusher being able to crush 300 tons of rock. The design of the cone crusher remained the same, but higher speeds and stronger chambers used in the crushers helped to increase the output.
The breakthrough in crusher design came from the hydraulic relief system that is a comparatively recent invention. This has helped to increase the life span of the crusher and also reduce its down time when repairs are necessary on the equipment. This in turn increases profit as well as productivity. Hydraulics is an invention that allows hard material like concrete to be crushed without any damage to the machinery and made for a major breakthrough in equipment for crushers.
There was a time when concrete that was retrieved from old buildings, roads and bridges that had to undergo demolition all made its way to landfills. Now it is more expedient to use the concrete crusher to break up the concrete and convert into material that can be reused. So the crusher arranges to clean and grind old concrete and make it available for the same customer's new projects. If the crushing is done on the site itself, the removal process becomes that much simpler. Old concrete is recycled and used as material for highways or other uses that are compatible with this crushed material.
There are many types of concrete crushers that also come in a variety of sizes. You can find mini concrete crushers that are self contained or others that are portable in nature. Stationary crushers are mainly used in facilities that only carry out such crushing work. You will also find certain construction equipment that is equipped with attachments that allow for concrete to be crushed. In these, the jaws can be interchanged depending on the nature of the crushing work to be undertaken.
Portable concrete crushers have become very popular, because they can be taken to a job site, and help to reduce the waste and debris that a construction site generates. The larger ones have capacities that can crush 600 tons of concrete every hour, while the smaller ones that are able to squeeze into smaller locations can take care of 150 tons during the same period. There are mini crushers that can even be hauled to the site by a pickup truck or even a car. Then there are attachments that need to be mounted on other construction equipment and can easily process 100 tons every hour.
Concrete crushers have changed the way companies now handle the way they make and use concrete. Contractors are able to use a concrete crusher to demolish and remove old concrete quite easily while also saving the costs of removal and demolition. The use of concrete crushers has also proved to be an earth friendly process and equipment now available can now be tailored to meet almost any need.
