How to choose the correct crusher for ore with different properties?

When choosing a crusher, in addition to looking at the characteristics of the crushed material, the discharge requirements are also key points that need to be referred to when choosing a crusher. Therefore, we need to understand the material characteristics and performance of different types of crushers.

4. Sand making machine: ideal equipment for machine-made sand.

Material properties:

1. Materials with high humidity, due to the castor plate, are discharged from the holes of the castor plate, because from the perspective of the humidity of the ore, the ore with too high humidity should not choose a hammer crusher. For example, clay mixtures, hammer crushers are suitable for crushing various hard and weakly abrasive materials. The compressive strength of the material does not exceed 100MPa, and the water content is less than 15%. Such as coal, salt, chalk, gypsum, brick, limestone, etc. are all crushed materials of hammer crusher.

2. High hardness material is a crusher that uses impact energy to crush materials. It is suitable for crushing some brittle and high hardness mineral raw materials. Do not use grinder crusher equipment or there will be too much fine grinding in the product.

3. Fragile materials with low hardness. For small and fragile ores such as shale, rock salt, gypsum, ordinary marl, broken sandstone, cemented conglomerate, and broken shale, there is no need to use jaw crushers to crush them. Hammer crushing is used. Crusher, Roller Crusher, Impact Crusher, Compound Crusher. For quartzite, basalt, granite, quartz porphyry, sandstone, limestone, iron ore, quartz veins, gravel, magnesium ore, marble, dolomite, pyrite, For high-hardness ores such as silica shale and shale-induced sandstone, it is necessary to choose crushing equipment with strong crushing capacity. For example, Jaw Crusher. Cone Crusher etc.
