Short Head Cone Crusher

Short head cone crusher was the world’s first cone crusher which is currently most widely used and has the largest stroking in the crushing equipment. It is widely applied in many industries, such as mining, metallurgy, construction etc. The final products size of short head cone crusher decides its working performance and application range. So analysis about factors affect final products size of short head cone crushermeans a lot.

Factors Affect Final Products Size Of short head cone crusher

Gap Between Eccentric Parts

The minimum size of discharge opening is the gap of frame bushing plus the gap of cone bushing. In the actual production process, if the discharge opening size is below the minimum size, then concaves and mantle will collides with each other, affecting the crushing efficiency. Sometimes, the actual minimum discharge opening size is different with the theoretical minimum discharge opening size, this is because the eccentric parts wear, leading to the gap increases.

Unstable Rotation Of Mantle

Unstable rotation of mantle is a series of abnormal motion state, such as the mantle moves up and down or turnover in the spherical bearing, caused by the improper design or installation. While the short head cone crusher works normally, the movable cone makes cone motion around the center line of frame. And then the distance between mantle and concaves decreases, and then increases, in this process, the raw materials got crushed. At the same time, the mantle bears reacting force from raw materials and rotates negative direction with the eccentric bushing.

When the work of short head cone crusher is abnormal, mantle moves up and down or turnover in spherical bearing, the distance between mantle and concaves loses control and changes frequently. In this case, one the one hand, we cannot adjust the discharge opening to normal size, on the other hand, now the short head cone crusher crushes raw materials with impact extrusion force instead of rotation extrusion force. The content of needle-like particles in the final products will increase.

Structure And Shape Of Scale Board

The structure and shape of scale board is another important factor affect the final products size of short head cone crusher. Scale board with reasonable shape can help to get good cubical final products. And the structure and shape of scale board should be designed according to the hardness of raw materials, the capacity required, and the shape of scale board after worn etc.
