Aggregate Coarse Crusher

What is Aggregate Coarse Crusher?

Aggregate Coarse Crusher is a device used to crush large stones to primary particle size. It is mainly used for primary processing of aggregates in construction, road and other projects. Its function is to crush the original ore or blasted rock into smaller particles, providing suitable raw materials for subsequent medium and fine crushing. This equipment can usually handle large materials with a feed particle size of 500-1500mm. It is crushed by jaw plate extrusion or hammering, and the output particle size can be controlled within the range of 50-300mm. The output can reach 50-2000 tons/hour depending on the model. Aggregate Coarse Crusher is particularly suitable for crushing high-hardness rocks (such as granite and basalt). It can effectively improve the overall efficiency of the aggregate production line and is a key first process equipment in the aggregate processing system. The crushed primary aggregate can be directly used for roadbed cushion or sent to the lower crusher for further processing.

What are the advantages of Aggregate Coarse Crusher?

Aggregate Coarse Crusher is specially designed for crushing various types of aggregates. It adopts optimized tool holder structure and alloy tools. It has a large crushing ratio, stable output, and uniform particle size. It is the core equipment for the production of building aggregates.

Large crushing ratio: With optimized tool holder design, a single machine can complete the work of traditional two-stage crushing, saving 30% of equipment investment.

Precise particle size: By replacing screens with different apertures, the output particle size can be accurately controlled between 5-100mm to meet various engineering standards.

Easy maintenance: Hydraulic opening design, it only takes 30 minutes to replace the tool and screen, reducing downtime losses.

What are the uses of Aggregate Coarse Crusher?

Aggregate coarse crusher is mainly used for primary crushing of aggregates with a particle size of 500-1500mm, such as high-hardness rocks (such as granite and basalt), medium-hardness ores (such as limestone and sandstone) and construction waste in construction, roads, bridges and other projects. Its core function is to crush large pieces of raw ore or rocks after blasting into smaller particles, providing suitable raw materials for subsequent medium and fine crushing or sand making processes. Specific uses include:

Construction aggregate production: crushing hard rocks such as granite, basalt, limestone, etc., to prepare coarse aggregates required for concrete and asphalt mixtures.

Roadbed cushion material processing: crushing large pieces of stone to a suitable particle size for laying foundation layers such as roads and railways.

Primary crushing in mines: after the stone is mined, the raw ore is initially crushed for easy transportation and subsequent processing.

What is the principle of Aggregate Coarse Crusher?

Aggregate coarse crusher mainly crushes aggregates by extrusion, impact and splitting. Aggregates are evenly fed into the crushing chamber of jaw crusher or gyratory crusher through vibrating feeder. Aggregates are squeezed by moving jaw plate or gyratory hammer head, so that they are crushed between fixed jaw plates to form larger particles. The crushed aggregates are screened by vibrating screen. Aggregates that meet the particle size requirements enter the next process. Oversized materials are returned to the crusher for secondary crushing. Qualified aggregates are transported to medium and fine crushing equipment or finished product yard by conveyor belt.
