Crushed aggregate is a combination of stone, gravel, sand, and slag, used in the construction of homes, infrastructure, spring cone crusher manufacturer businesses, and roads. Crushed aggregate is made from natural raw materials and making it involves the use of several heavy machines. Once the process is finished, the result is crushed aggregate, a material the construction industry can't do without.
The Jaw Crusher
Large rocks are mined from gravel pits or quarries and transported to the surface, where they are usually placed in dump trucks. Once on top, the rocks are sifted for smaller pieces and debris with the aid of a powerful vibrating conveyor belt. The conveyor belt transports the materials to the jaw crusher, which is really the first step in aggregate crushing. The jaw crusher is made of two plates, rather like a human mouth. It crushes the rock between the two plates and then "swallows" it, pouring it out onto another conveyor belt, which takes it to an impact crusher.
The Impact Crusher
An spring cone crusher flings the rocks against hard plates, causing them to split and break into much smaller pieces. They're then put on a vibrating screen, which acts as a large filter through which the crushed aggregate is sorted by size. The finer the aggregate needed, the more it gets filtered; this allows quarries to sell different types of crushed aggregate to customers, based on the project at hand.
Dump Trucks
Crushed aggregate is then transported to the work site by dump trucks. Most crushed aggregate is produced within forty miles of where it's used, though longer distances are not unheard of, and about ninety percent of it is transported by dump trucks.
Other Machines
Of course, there are many other machines involved in aggregate crushing. The hydraulic cone crusher is good for crushing rocks into medium, fine, or super-fine grade aggregate, and can be adjusted according to what the customer needs. A spring cone crusher is used for rocks of medium-to-hard hardness levels, and has a variable-sized crushing chamber. A sand-maker crushes rock, including metal ores, into extremely fine aggregates, while a drying hammer crusher is a floor-to-ceiling machine that specializes in soft or moist raw materials. Finally, a ring hammer crusher specializes in both moist and dry aggregates, and pounds them down to size with a series of hammers.
Aggregate crushing is a long, laborious process, involving a number of stages and several pieces of heavy machinery. Regardless, crushed aggregate is a necessary component of almost any Mobile VSI Crusher project.
