For manufacturers, gravel crusher is the most important yield is higher , reducing the amount of sand and gravel processing equipment manufacturers, is a very serious matter . Next YiFan Machinery on to analyze the cone crusher capacity is reduced.

If the cone crusher " hoard material " phenomenon , it will cause lower capacity . Want to learn the cause of the crusher feed store , the first condition for stable operation of the crusher must be clear . The so-called cone crusher motor stable operation refers to whether the moving cone overturned on spherical bearings, if overturned , crushing machine is running unstable.

When running the crusher , crushing cone axis of the center line of the body movement of the conical surface , its apex is the center of the spherical bearing O points. O point in the process of crushing cone movement always remains stationary , thus crushing cone movement can be regarded as a rigid body rotating around a fixed point . Another crusher run , you must ensure that the centerline of the main axis of the cone crusher and crusher in the sphere center intersect. Otherwise, it will undermine the work of the crusher. It can be seen , the cone during operation , moving cone centerline axis of the rack must focus O1 -watt bulb spherical center O coincide , which is a prerequisite for the normal operation of the moving cone .

In addition, to ensure that the cone crusher motor will not tip over when the overhaul must make the entire spherical bearing contact area of ​​2 / 3 in the outer ring, ring size in 1/ 3 of the time to contact after running for some time , you can reach the whole area uniform contact .

Closed-circuit breaking capacity is calculated as follows:

Where Q is closed when the closed-circuit crushing crusher production capacity ; Q is open when you open the crusher crushing capacity ; K is the average feed size tapering coefficient closed ; K1 ore can be broken coefficient ; K2 is the ore particle size correction factor ; q0 is the crusher production capacity per unit width mouth ; was crushed ore bulk density ; b is the width of the crusher discharge mouth during production.

Actual production, assuming the nature of the travel time is constant ore crusher selection must , K, K1, K2, q0, are constant, therefore , at this time only the capacity of the crusher and discharge mouth width related.

Production process adjustments port of discharge , not transferred to the specified size, the moving cone will collide with a fixed liner occurs crushing chamber opening gap and the gap is not a port of discharge gradually from large to small or from small to big , but no rules suddenly change into small , can not effectively crushed ore crushing machine will not be able to achieve proper processing capabilities. Cavity does , crusher parallel with the length differences will exist , will also affect the crusher capacity .

For more than a few problems YiFan Machinery provides the appropriate solution for your reference.

( 1 ) only to ensure stable operation of the moving cone , in order to ensure capacity crusher . If the manufacture of the eccentric bushing , the eccentric axis position is not correct , the offset may be adjusted relative to the position of the eccentric sleeve tile bowl by increasing or decreasing the gasket between the bowl and the bowl tile holder tiles methods to achieve Q Q1 coincides with the point . If the difference between the larger eccentric axis , Q1 and Q points or incorrect because the eccentric angle caused no coincidence , only by replacing the eccentric axis angle and the correct position of the eccentric sleeve to solve.

( 2 ) If there is a problem crushing cavity , first find the problem fixed cone or cone moving through the replacement parts to solve.

I hope these few suggestions YiFan machinery provided to help reduce the amount of processing to resume normal cone crusher , thereby protecting the gravel plant production efficiency.
