Efficient artificial stone crusher price
Impact crusher and under what circumstances to use more first is the coal mining industry, the number of usage crusher used in the coal mining industry is the largest, probably accounts for 50 percent of the total coal, more most crusher are concentrated on the use of a large coal mines. Followed by stone mining, stone crusher is most suitable for use crusher, mobile crusher best is none other than mining and quarry. Impact crusher is also used in a number of iron ore, copper, gold and other metal ore class. There are relatively substantial amounts. Raw materials and broken cement industry is now very extensive user crusher. The final step is garbage, no fragile country has a lot of garbage daily, such as the amount of discarded trash cans, glass, tires, etc. are great amazing, and impact crusher can run their own performance, as someone pulling in recycling resources.
Impact crusher is efficient in absorbing foreign advanced technology combined with the domestic industry specific working conditions and the development of the latest generation of counter-efficient crushing machine. Introducing the jaw crusher for crushing various models of medium hardness of solid materials in the cement industry, crushing limestone, gypsum, clinker, mixed materials. Also crushing calcium phosphate, dolomite, perlite ore. Can be widely used in building materials, fertilizers, mining and refractories and other industrial sectors. Counterattack crusher efficient technologies, some of which major improvements:
1 spindle and bearing both uniform fine contact, but also have some with the gap, so that on the outside lower portion of the contact angle of the spindle bearing and form an oil wedge and wedge starting watts maximum gradual transition from the mouth to zero.
2 contact angle is not too large nor too small. The contact angle is too small, will increase the bearing pressure, severe bush will have a greater deformation, accelerated wear and shorten life; contact angle is too large, it will affect film formation, destruction lubrication. Accordingly, the pad does not affect the pressure conditions of the premise, the smaller the contact angle, the better.
The actual scope of the contact angle of contact within 3 spots more, more detailed, more uniform as possible.
