Crusher has the features of big crushing ratio, even granularity, simple structure, reliable operation, convenient maintenance, economical operating expense. It is widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industry etc many industries. Crushing compression strength is not more than 320MPa all materials.

The reasons of jaw crusher uneven discharging granularity: when jaw crusher discharging granularity is particularly uneven, discharging granularity is very low. Then we should how to solve the problem. we will introduce the matter of low discharging materials rate:Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing.

1.motor connection place is converse. Main machine drives conversely or motor triangle is connected into star shape.

2.Jaw plate displace, gear top is opposite to gear top.

3.The gap after movable jaw and bearings wear is bigger which make outer cycle of bearings opposite rotation.

4.Discharging opening is smaller than limits.

5.Hardness or toughness of crushed materials exceeds the specific range of instructions.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,spray dryer,mineral ore Welcome all of you to visit our official website.hammer mill:http://www.china-hxjq.com/n255.html

6.Working site power pressure is lower.

Working principle of jaw crusher: motor drive belt and belt wheel by eccentric shaft movement up and down. When movable jaw rises, the angle of bracket and movable jaw will be large and push movable jaw plate near fixed jaw plate. Meanwhile materials will be crushed or cracked to reach up to the crushing purpose. When movable jaw moves down, the angle of movable jaw and bracket will be smaller. Under the action of rod, spring movable jaw will leave fixed jaw plate. At this time crushed materials will be discharged from crushing cavity down opening. Eccentric shaft usually use concentrated recycle lubrication. Support surface of center shaft and push power board generally use lubrication fat by manual oil spraying. Swing angle of movable jaw is very small which make lubrication between center shaft and push power plate is quite difficult. As usual we open oil grooves at the bottom of bearing bush . the middle will open a ring and make it connect. Then oil pump is forced to pour dry butter to lubricate.
