The strength and fragility of the material introduced

The general performance of the material crushing strength of the degree of difficulty, also known as the fragility of the material. The same crusher crushed under the same

operating conditions of different materials, the production capacity is different, indicating that a variety of materials different friability.

Friability and the material strength, hardness, density, uniformity of the structure, water content, viscosity, cracks, surface condition and the shape factors.

Material strength and hardness are expressed resistance to external force, the strength and hardness of the material is difficult to Grand broken. But the mere hardness of the

material is not necessarily hard to broken, because the material is a block broken split open, so the crusher manufacturer difficulty determining factor is the material strength. The

hardness of the material must be very difficult grinding, crushing process because the grinding process and the different mill grinding process is the body of the material

surface constantly working to generate a large number of fine grinding process, therefore I decided to ease grinding factor is the material hardness.

Uneven nature of the natural material, the same material measured intensity data vary greatly. Therefore, in practical work often measured hardness of the material, the hardness

of the material to some extent reflects the ease of stone screening machine the material, the hardness of the material so that their common friability.
