Crushers are construction machines used for crushing various materials, such as concrete, stone, limestone, brick, rubble, asphalt, soil, and others, in order to reduce their volume and prepare them for further use. Crushers are commonly used in construction, for example, for recycling construction waste, creating foundations for roads, or producing building materials.
Crushers are divided into several types depending on their mode of operation:
Jaw crushers - crushers equipped with a movable jaw that squeezes and crushes the material. Most commonly used for crushing stones with high hardness.
Impact crushers - crushers that use the force of impact to break down the material into smaller pieces. In this case, the material is introduced into a special chamber where the kinetic energy of the impact tool works.
Cone crushers - use horizontal movement to grind the material to a specific size. They are more efficient than jaw crushers, but less efficient than impact crushers.
When choosing a crusher, several factors should be taken into account, such as:
the type and hardness of the material to be crushed;
required efficiency;
size of the machine and its mobility;
purchase and operating costs;
availability of spare parts and service.
It is important to choose a crusher with the appropriate efficiency and power that will be able to crush the material according to the requirements. The size of the machine is important because it must be adapted to the work site and also take into account transportation needs. Purchase and operating costs are important factors, and the availability of spare parts and service is necessary to ensure uninterrupted machine operation in case of breakdown or repair needs.
