Therefore, the production of wear parts of crusher must be strictly. The quality of crusher wear parts has great influence on the service life of jaw crusher, if the quality of crusher parts is good, the wear and tear of jaw crusher equipment will be less.
In actual life, discharge opening should be adjusted according to required discharging granularity. Therefore, at the request of guarantee the product size, enlarge discharge opening as far as possible is reasonably. The discharge opening can be adjusted by adjusting the block, and the correlation between reduction ratio and productivity should be paid attention when adjust the discharge opening.
Main factors affecting the working hour of jaw crusher are biting angle and revolution. The biting angle is the included angle of fixed jaw and movable jaw. According to the calculating, maximum biting angle can be up to 32 degrees, generally is 18-20 degrees. If the biting angle is too large, the ore in crushing chamber will be upward extruded, resulting in injury or damage on other jaw crusher equipment, and increased biting angle will decline the productivity.
The discharge opening of jaw crusher is related to its productivity, so it should be adjusted according to required discharging granularity. At the request of guarantee the product size, enlarge discharge opening as far as possible is reasonably. Therefore, the government should control the number of gravel mining of rock and centralize the decentralized set of resources; encourage small business to combine with large business to efficiently use resources and improve sand quality on the market.
