A crusher is a machine that breaks large rocks, stones, or minerals into smaller pieces. Its purpose is to reduce material size to desired dimensions. It usually operates using a motor or mechanical power, employing jaw, cone, or impact mechanisms to crush material. Crushed material is then screened and sorted by size. Crushers are widely used in construction for aggregate production, in mining for ore preparation, and in infrastructure and road building.

What is a mobile crusher, what does it do, how does it work, and where is it used?

A mobile crusher is a crushing and screening plant mounted on wheels or tracks, designed for easy transportation. It typically runs on diesel or electric power. It can be quickly set up on-site and used in multiple locations. It is preferred especially in mining sites, road construction, building areas, and urban renewal projects.

What is a fixed crusher, what does it do, how does it work, and where is it used?

A fixed crusher is a large, high-capacity crushing and screening plant permanently installed at a specific location. Material is fed by trucks, crushed, screened, and conveyed to storage. It is used in projects requiring continuous high-volume production such as dams, highways, ports, and large construction works.

What are the differences between fixed and mobile crushers?

  • Mobile crushers are portable; fixed crushers are stationary.

  • Mobile crushers can be installed and dismantled quickly; fixed crushers take longer to set up.

  • Fixed crushers have higher capacity.

  • Mobile crushers offer flexible use; fixed crushers are suited for continuous production.

  • Mobile crushers have higher initial cost; fixed crushers can be more economical long-term.

What is a river sand washing and screening plant, what does it do, how does it work, and where is it used?

A river sand washing and screening plant cleans sand taken from riverbeds by removing clay, silt, soil, and other impurities through water and mechanical action. After cleaning, the sand is classified by size for use in concrete, mortar, infrastructure fill, and other construction materials. The plant works by washing sand with water, screening it through sieves, and collecting the clean product.
