What Should Be Concerned About When Crushing Ores with High Hardness

When crushers crush some ores with high hardness, such as basalt, granite and cobble, enough attention should be paid on whether the design of crushing process by different crushers is available, and on the whole costs including investment costs and production costs.

Influence factors of broken stone: broken material to type and hardness. The content of silicon material, moisture content, Crushing material to average particle size, finished product grain and each particle size range ratio requirements; Finished product to use; Hours production; In the actual ground broken assignments, some customers to raw material is limestone, jaw crusher to jaw loss is very low, a pair of jaw to use life to achieve a year is a very common phenomenon in; This is because the limestone not only hardness is very low, and the stone that silicon content is very low, the crusher to wear a land abradability is very low.

In the raw material is basalt, granite to crushing assignments, crushing equipment production cost is more than limestone to production cost; Therefore, we design for crushing process, should as far as possible choose laminated principle to crushing equipment, so can reduce the wear parts to loss; Typical formation pressure equipment configuration is two stage jaw broken or jaw broken and cone broken to process configuration; If the customer to eventually stone grain type has a high requirement, we could configuration a counterattack crusher for integer broken, thus formed the three stage crushing process configuration of land; Three stage crushing inevitably leads to the project investment cost is higher, but for long-term operation to ShiLiaoChang, three stage crushing to reduce the cost of production is very considerably; For difficult to break ground material, also can use jaw broken and counterattack broken two stage crushing process; However, this will inevitably lead to counterattack broken floor hammer loss is very high, plate hammer life is short, the...
