CN2577950Y - Lining plate structure of cone crusher - Google Patents

Abstract

The utility model discloses a lining plate structure of a cone crusher. The upper part of a lining plate in a crushing cavity of the cone crusher is a step shape, and the lower part is a parallel shape, and moreover, the upper part and the lower part are properly extended. The lining plate of the cone crusher is a bimetallic composite lining plate alternately cast by alloy 1 and alloy 2; the hardness and the antiwear characteristic of the alloy 2 are lower than that of the alloy 1. The original structure can not be changed by using the utility model, and thus, the modification is simple. A nip angle of the crushing cavity is big, which can raise processing ability; the size and the capacity of a material inlet of the upper part are big, which can increase the crushing ratio, and the crushing between material beds can be formed.

Description

The lining plate of cone crusher structure

The utility model relates to a kind of lining plate of cone crusher structure.

Traditional gyratory crusher is because the ubiquity feed port is little, the parallel broken head of district, the number of oscillations of mantle per minute is low, exist microscler, laminar ore without fragmentation just from the crusher chamber phenomenon of landing voluntarily, marker size is thick, production capacity is low, the energy consumption height.In addition, the structural design of traditional round conic crusher chamber shape with along the handling capacity in each cross section of crusher chamber height require inharmoniously, and be not quite similar in handling capacity when broken along each cross section of crusher chamber height.

The purpose of this utility model is to provide a kind of lining plate of cone crusher structure, to overcome above-mentioned deficiency.

Scheme of the present utility model is:

Liner plate top in the cone crushing chamber is notch cuttype, and the bottom is a parallel shape, and proper extension.

The duplex metal composite lining board that lining plate of cone crusher is alternately cast by alloy 1 and alloy 2, the hardness of alloy 2 and antiwear characteristic are than the end of alloy 1.

The utility model has increased the epicoele height of crusher chamber, reduces material and swings the displacement that is produced in all processes at mantle, increases the epicoele dischargeable capacity, dwindles the epicoele diameter.Reducing the difference of each cross section handling capacity, thereby realize the lamination fragmentation, improve production capacity and increase the ratio of reduction.

Fig. 1 is the main cutaway view of the utility model in crusher chamber;

Fig. 2 is preceding alloy 1 and the position relation of alloy 2 in liner plate for the utility model uses;

Fig. 3 uses back alloy 1 and the alloy 2 position relation in liner plate for the utility model.

Now be further described below in conjunction with the accompanying drawings:

With the 1650[brachycephaly] gyratory crusher is example, the utility model is contained in the crusher chamber by Fig. 1, in the broken material+the 18mm grade reduced by 50%,-15mm grade increases more than 40%, the treating capacity of-15mm grade is brought up to about 180t/h by original 130t/h, and production capacity has improved 38.46%; The unit power consumption of-15mm grade is transformed preceding identical with chamber shape.

Claims (2)

1, a kind of lining plate of cone crusher structure is characterized in that: the liner plate top in the cone crushing chamber is notch cuttype, and the bottom is a parallel shape, and proper extension.

2, lining plate of cone crusher structure according to claim 1 is characterized in that: the duplex metal composite lining board that lining plate of cone crusher is alternately cast by alloy (1) and alloy (2), the hardness of alloy (2) and antiwear characteristic are lower than alloy (1).
