Stone Coarse Crusher

What is Stone Coarse Crusher?

A stone coarse crusher is a machine that breaks down large stones into smaller, coarse particles to meet specific requirements. It crushes large stones such as granite, limestone, and basalt into smaller particles through compression or impact, providing raw materials for subsequent medium and fine crushing or concrete production. It is generally used for primary stone crushing, with a feed size of 500-1500mm and an output size that can be adjusted according to needs, typically from 100mm to 300mm. The crushing capacity ranges from 500 to 800 tons per hour, and it can be used in everything from small quarries to large mining production lines.

The stone coarse crusher can crush stones of varying hardness. Durability is a key consideration in material selection; high-manganese steel or wear-resistant alloys are used for core wear parts such as jaw plates and hammers. The machine body is welded from high-strength carbon steel, offering impact resistance and wear resistance, ensuring stable operation under heavy loads.

What are the types of Stone Coarse Crusher?

Common types of stone coarse crushers include jaw crushers and impact crushers. They differ in their working principles, types of stone they can crush, feed and discharge particle sizes, and crushing capacity. The appropriate equipment can be selected based on the properties of the material to be crushed.

Jaw Stone Coarse Crusher: This type crushes stone through compression between a stationary jaw and a moving jaw. When the moving jaw approaches the stationary jaw, the stone is crushed; when it moves away, the crushed stone is discharged from the outlet. It has a simple structure, stable operation, and can be used for crushing high-hardness or medium-hardness materials such as granite, basalt, and iron ore. Feed size range is 500-1500mm, discharge size is 100-300mm, and crushing capacity is 100-800t/h.

Impact Stone Coarse Crusher: It relies on a high-speed rotating rotor to drive hammers to strike and impact the stone. The stone is repeatedly crushed under the impact force, with a large crushing ratio and uniform output particle shape. It can crush medium-hardness and brittle stones such as limestone, marble, and shale, but it is not suitable for crushing high-hardness materials. Its feed size is 300-800mm, output size is 50-200mm, and crushing capacity is 50-500t/h.

What are the advantages of Stone Coarse Crusher?

The Stone Coarse Crusher features a widened feed inlet design, capable of crushing large stones up to 1500mm in diameter. The crushing chamber structure is selected based on the type of stone being crushed, and combined with wear-resistant jaw plates or hammers, it easily handles the intense wear and impact from stones of varying hardness. It is robust and durable, reducing material blockage and ensuring stable operation. With a large crushing capacity of up to 800 tons and high crushing efficiency, it can quickly crush large stones to a uniform coarse particle size, preparing them for subsequent processing. The output particle size can be adjusted according to the standards of the crushed stone.

How does Stone Coarse Crusher work?

After being fed into the crushing chamber through the inlet, the Stone Coarse Crusher is crushed by mechanical forces such as squeezing, impact, and splitting generated by the motor. The crushed stones that meet the specifications are discharged from the outlet through the screen, while the stones that do not meet the specifications continue to be crushed in the crushing chamber until they meet the standards and are discharged.
