破碎

破碎 is often one of the first steps in the production of rock, coal and other minerals, as mined material can consist of boulders that are 太 big to fit through the processing plant. The type of crusher required depends on the material being reduced. 菠菜网最稳定正规平台_最全菠菜网大全 specializes in a variety of crushing solutions for reducing minerals – from very friable minerals, such as coal and salt, 到坚硬的岩石, 比如花岗岩, and ore-bearing minerals, such as copper and iron – at the primary, secondary and tertiary stages using compression, 影响, attrition or shear forces.

Compression 破碎

Crushers that employ the forces of compression squeeze material between two surfaces, one stationary and one mobile, in order to achieve reduction. As feed material advances downward through the chamber, it is crushed between the moving piece of steel and the stationary plate. Only material that has reached the desired size passes on to the next stage in the process; whereas the larger material remains subjected to repeated pressure in the chamber until it, 太, reaches the desired size. Gradation is controlled by adjusting the spacing between the stationary plate and the moving plate at their closest point.

Compression crushers can be used at the primary, secondary or tertiary stage, depending on the application. They are ideal for hard, tough and abrasive materials that are not sticky.

Types of Compression Crushers

影响粉碎

Impact crushing reduces material by utilizing the theory of mass versus velocity in two ways. 一种方法是, material can be broken by its collision with hammers that are fixed to a spinning rotor. The material is broken mainly by its initial 影响 with the hammer and then further reduced by its 影响 against the breaker plates. Inter-particle collisions and particle-on-particle attrition also break down the material.

The other method involves the material being thrown at high speed against a solid anvil, breaking the material along its natural fissure lines. The particle size is controlled by how fast and how far the material is thrown.

With both types of 影响 crushing, material that has reached the desired size falls through the chamber, while the larger pieces remain subject to further 影响. Both hard rock and soft material can be reduced using 影响 crushing.

Types of Impact Crushers

剪切破碎

Crushers that utilize shear forces to achieve the desired size and shape reduce material by trimming or cleaving. Material trapped between a solid plate and a rotating roll is shorn by its contact with the teeth on the roll. 通常, shear crushing is combined with other crushing methods, 比如压缩, 磨损和冲击, for mineral size reduction.

Shear crushing is ideal for crushing friable material or creating a coarse product at the primary crushing stage.

Types of Shear Crushers

摩擦粉碎

Attrition crushers employ the theory of mass and velocity with a grinding action to reduce feed material. These types of crushers scrub material between two hard surfaces to achieve reduction in size and shape. Particles are reduced by their contact with other particles or by their contact with a rigid face.

Crushers that use the forces of attrition provide a high reduction ratio. They are best suited for friable, less abrasive materials.

Why 菠菜网最稳定正规平台_最全菠菜网大全 破碎 Equipment

菠菜网最稳定正规平台_最全菠菜网大全 crushing equipment accepts feeds of large material and reduces the material to the desired product size. Because each crusher type has a limited reduction capability, sometimes several stages of crushing are needed to achieve the desired final product size. Primary crushers are important for kicking off production and initial product sizing for further processing. They receive the material directly from the blasting, drilling or dredging process. Secondary and tertiary crushers are utilized for additional refinement of the material.

Employing one or more of these basic reduction principles, 菠菜网最稳定正规平台_最全菠菜网大全 crushers achieve the desired product size and shape at maximum volume and with minimum power consumption and wear on the machine.

With any crushing application, the goal is to produce the required product sizes at the lowest cost per ton while maximizing the throughput. 菠菜网最稳定正规平台_最全菠菜网大全’s crushing solutions allow producers to yield the sizes they need while operating their equipment at maximum design capacity.
