Crushing machines for the purpose of preparing aggregates, including sand and gravel in the required sizes, especially in the preparation of concrete aggregates and other cases that require aggregates in granulation ranges, such as road pavement and asphalt layers. It is used.

The different components of the stone crusher plant vary according to the size and type of the plant, but generally they are placed according to the following order: - Coarse filter where the primary raw materials are fed into the crusher after passing over it. This conveyor consists of a set of parallel bars, through which small materials that do not need to be crushed first fall, thus preventing the unnecessary erosion of the crusher. The small material falls directly onto the primary conveyor which carries the crushed product of the first crusher. - The warehouse system, which consists of a set of containers under the silos with a series of conveyors that transport the granulated materials to the warehouse. - The primary stone crusher, which has the task of crushing raw materials into coarse aggregates. - Primary feeder on which raw materials are poured. This feeder can be a simple hopper or a chute with a heavy duty conveyor. The purpose of this feeder is to regularly deliver the material to the primary crusher. - Separating filter that separates materials into two categories "acceptable" and "oversized". The second material goes to the secondary crusher, while the acceptable material goes directly to the primary crushers. - The secondary crusher that converts larger materials into acceptable sizes. - Secondary conveyor belt (elevator) that transports the re-shredded product (and in some cases the acceptable material of the separating sieve) to the main sieves. - The main mills that divide all the materials into certain grades before being stored. If the aggregates need to be washed, this is done in this place. - The primary conveyor (elevator) that transports the crushed material to the separator, this belt passes under a magnet to separate the bits of steel drill, screw or pieces of iron that damage the secondary crusher. . - If the production of sand is also considered, the suitable materials are transferred from the mills to the sand making machine to be granulated again by further crushing.
