Ore crushing device capable of protecting lining plate against falling off

Abstract

The invention discloses an ore crushing device capable of protecting a lining plate against falling off. The core crushing device capable of protecting the lining plate against falling off is characterized by comprising a stainless steel crushing box body, reverse striking plates, reverse striking frames, a reinforcing lining plate, a crushing feeding inlet, a crushing base, plate hammers and a rotator frame; a protruded bolt head hook is installed in the middle of one side of the reinforcing lining plate, and a long groove is formed in the bolt head hook; a through hole matched with the bolt head hook is formed in the corresponding position of the stainless steel crushing box body, a bolt head of a bolt is placed in the bolt head hook, and a lining plate pressing cap is installed in the bolt head hook; and a nut is installed on the outer side of the lining plate pressing cap through a bolt. When the crushing device works, the bolt head of the lining plate is placed in the bolt head hook, and does not rub with stone materials in a crushing cavity, so that the bolt head is not damaged, the lining plate does not fall off the crushing cavity, and a machine is not destroyed, and accordingly, the service life of the lining plate is greatly prolonged; and in addition, the lining plate does not need to be replaced frequently, so that producing cost is effectively reduced, producing efficiency of the machine is improved, and producing cost is reduced.

Description

technical field [0001] The invention relates to the field of ore crushing, in particular to an ore crushing device for preventing liners from falling off. Background technique [0002] Crushing and grading refers to the operation of reducing the particle size of mineral raw materials and having certain particle size distribution characteristics through certain mechanical equipment. Usually, the operation of reducing the particle size to 20-5mm is called crushing, and the corresponding equipment is a crusher; the finer crushing operation is called grinding, and the corresponding equipment is a grinding machine; it is matched with the crusher and the grinding machine to control the final The operation of product particle size distribution is called classification. The classification equipment matched with the crusher is generally called a screening machine or a vibrating screen, and the classification equipment matched with a mill is called a classifier. [0003] Usually, cru...

Problems solved by technology

[0004] The existing ore crushing equipment has complex structure, high power consumption, high maintenance cost, and is very inconvenient to operate; for crushing equipment, during the process of crushing stones, the stones will continuously hit and wear the exposed bolt heads, causing lining After the plate falls off, it falls into the crushing cavity and damages the crusher; on the other hand, in order to prevent such accidents, it is necessary to stop frequently to disassemble and replace bolts and liners, resulting in a low actual operating rate of the crusher, which seriously affects the construction process

Moreover, the manufacturing cost of the liner is high, and the high damage rate will greatly increase the production cost of the crusher; so it needs to be improved
