Abstract

The utility model relates to a crushing toothed roll of a toothed roll crusher, in particular to a split type compound crushing toothed roll, which comprises a flange and a crushing tooth and a roll drum which constitute an integrated structure, wherein the flange and the roll drum are independent individuals, and the flange is placed in the interior of the roll drum and fixedly connected with the roll drum. Compared with the prior art, the split type compound crushing toothed roll has simple structure, convenient production, low production cost, short cycle and long service life under the premise of ensuring the wear resistance.

Description

Split type composite breaking discaling roll

Technical field

The utility model relates to the broken discaling roll of rod-toothed crusher, particularly a kind of split type composite breaking discaling roll.

Background technology

Broken discaling roll is the main broken parts of rod-toothed crusher, and its anti-wear performance is the key point in disintegrating machine operating efficiency and service life.The approach that solves broken discaling roll wearability problem at present both at home and abroad has two kinds: a kind of is after the discaling roll mother metal is cast with steel alloy, the build-up wear-resistant material, and the wearing layer of this crushing teeth is thinner, adopt manual welding, labour intensity is big, and operation is random big, and its service life is generally about three months; Another kind method is the monoblock cast abrasion-resistant stee, though the service life of this crushing teeth is longer, mainly is the crushing teeth wearing and tearing during owing to work, monoblock cast has improved production cost, and hardness is higher after the monoblock cast, needs the operation through rough turn-heat treatment-finish turning, and processing cost also increases.

Summary of the invention

The utility model is to eat discaling roll monoblock cast defect of high cost at fragmentation in the prior art, provide a kind of make simple, cost is low, the split type composite breaking discaling roll of long service life.

Realize that the technical scheme that above-mentioned purpose adopts is: a kind of split type composite breaking discaling roll, comprise flange, and the crushing teeth of integrative-structure and roller, described flange and roller are independent individual; Flange places roller inside, and affixed with roller.

Compared with prior art, the utility model is under the prerequisite that guarantees its anti-wear performance, and simple in structure, easy to make, production cost is low, the cycle is short, long service life.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: crushing teeth 1, roller 2, flange 3.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

Referring to accompanying drawing 1, in the present embodiment, this split type composite breaking discaling roll comprises flange 3, and the crushing teeth 1 of integrative-structure and roller 2, and flange 3 is independent individual with roller 2, and flange 3 places roller 2 inside, and affixed with roller 2.

In order to guarantee the anti-wear performance of broken discaling roll, its crushing teeth 1 and roller 2 adopt the wear-resisting alloy steel casting to form; In order to reduce production costs, to be used for flange connecting 3 and to adopt the ordinary carbon steel casting to form; Be fixedly connected between flange and the roller, guarantee the stability of broken discaling roll integral body.

Claims (1)

1. a split type composite breaking discaling roll comprises flange, and the crushing teeth of integrative-structure and roller, it is characterized in that described flange and roller are independent individual; Flange places roller inside, and affixed with roller.
