Stone Coarse Crusher

What is Stone Coarse Crusher?

Stone Coarse Crusher is a key equipment in the mining, building materials, road and railway construction industries. Through jaw crushing, hammer impact, mobile crushing and other technologies, large stones (such as granite, limestone, basalt, etc.) are crushed into smaller particles to provide raw materials for subsequent medium and fine crushing, sand making or concrete aggregate production. Compared with ordinary crushers, stone coarse crushers have higher crushing ratios, stronger wear resistance, and are optimized for the hardness characteristics of stones to ensure efficient crushing and stable operation.

What are the types of Stone Coarse Crusher?

According to the crushing principle and applicable scenarios, Stone Coarse Crusher can be divided into: jaw type, heavy hammer type and mobile type, which can be selected according to the material characteristics:

Jaw type Stone Coarse Crusher: crushes stones through the extrusion movement of the movable jaw and the fixed jaw, similar to the "chewing" action, suitable for high hardness (compressive strength ≤ 320MPa) materials such as granite, basalt, iron ore, etc., feed size: 120-1500mm, discharge size: 10-400mm (adjustable).

Heavy hammer Stone Coarse Crusher: uses high-speed rotating hammers to impact stones to achieve "one-time" crushing, suitable for medium and low hardness materials (limestone, coal gangue, shale, etc.), feed size: ≤1200mm, discharge size: ≤30mm (some models can be formed in one time)

Mobile Stone Coarse Crusher (crawler/tire type): comes with a diesel engine, does not require fixed installation, can quickly transfer operations, suitable for temporary quarries, construction waste recycling, and remote mining areas.

What are the advantages of Stone Coarse Crusher?

Stone Coarse Crusher is specially designed for stone crushing, with large-diameter feed, high crushing ratio and adjustable discharge port for crushed stone particles.

Large feed opening design: can handle stones up to 1200-1500mm, reducing the need for pre-crushing

High crushing ratio: adjustable discharge particle size (10-400mm), suitable for different production needs

Sturdy and durable: high manganese steel jaw plate, strong wear resistance, long service life

Strong adaptability: can crush high hardness materials (compressive strength ≤320MPa), such as granite, iron ore, etc.

How does Stone Coarse Crusher work?

Stone Coarse Crusher mainly crushes materials by squeezing, impacting, splitting, etc.:

Jaw Stone Coarse Crusher: The motor drives the eccentric shaft, so that the movable jaw plate periodically approaches the fixed jaw plate, and the stone is squeezed and crushed between the two jaw plates.

Hammer Stone Coarse Crusher: The high-speed rotating hammer hits the stone, combined with the impact plate for secondary crushing, to achieve "one-time forming".

Mobile Stone Coarse Crusher: Integrated feeding, crushing, and screening functions, the stone is coarsely crushed on the crawler/tire mobile platform

What are the applications of Stone Coarse Crusher?

Stone coarse crusher is used to crush stones of different shapes and sizes into smaller stone particles. It can be used for iron ore, copper ore, granite, limestone, gypsum, quartz sand, sandstone aggregate, artificial marble, road/railway construction and construction waste treatment, etc.
