Abstract

The invention relates to the technical field of stone crushing, and discloses a conical crusher.A pulley is contacted with an arc surface at the bottom of the outer surface of the conical crusher, the axis of an elliptic swing shaft and the axis of a main shaft are not the same center line any more in the rotating process of a crushing device, and the axis of a swing hole and the axis of the elliptic swing shaft are positioned on the same center line. Make breaker can sway at the pivoted process, the position change of the minimum of the process toper breaker bottom that breaker sways drives and breaks away from the board and uses the axis of spring shaft to rotate as rotation center, make the space increase between the board and the adjacent board that breaks away from that contacts with toper breaker bottom minimum, make the building stones that break away from the board top that contacts with toper breaker bottom minimum can fall through the effect that the space increases, thereby avoid unqualified building stones too much and block the space that breaks away from between the board thereby lead to the size normal rubble can't pass through the space between the board, the stability of the device has been improved.

Description

Conical crusher

Technical Field

The invention relates to the technical field of stone crushing, in particular to a conical crusher.

Background

One kind in the breaker during the cone crusher, the swing of the cone crushing body through the axis skew makes the continuous emergence of distance between its surface and the shell inner wall change, make building stones can receive extruded effect and take place breakage after getting into the space between the two, thereby realize crushing effect, because the cone crusher often applies to once broken or secondary crushing, building stones can not carry out careful screening after getting into broken chamber, often lead to some comparatively hard building stones of texture to get into in broken chamber and lead to the cone crushing body card owner and unable rotation, hydraulic lifting device can drive broken shell and carry out the lifting this moment, thereby make the distance between shell inner wall and the cone crushing body enlarge, thereby get rid of unable broken building stones, guarantee the stability of equipment operation.

Although the method can solve the problems, the conical crushing body is clamped, meanwhile, a lot of stones still exist in the crushing cavity, part of the stones are not subjected to crushing operation, after the crushing shell is lifted, the stones which are not crushed can be discharged together with the stones which cannot be crushed and mixed with crushed stones which are crushed, so that the quality of the produced product is reduced, in addition, the conical crusher lacks the function of screening the crushed stones, so that the quality of the crushed stones is uneven, the subsequent treatment of the product is required, and the production cost is increased.
