Description
Technical Field
The utility model belongs to the technical field of mining machinery equipment, a semi-autogenous mill end liner is related to.
Background
The semi-autogenous mill is a kind of grinding equipment widely used in the field of electric power, ceramics, cement and mineral processing. The basic working principle is as follows: the semi-autogenous mill cylinder rotates at a certain rotating speed, and grinding balls at the bottom of the ball mill cylinder are attached to a cylinder liner plate under the action of centrifugal force and friction force. When the grinding balls are brought to a certain height, the grinding balls are thrown down due to the gravity of the grinding balls, and impact crushing and grinding are carried out on the grinding materials at the bottom of the cylinder body. The lining plate is a key wear-resistant part of the ball mill, the lining plate is worn and thinned under the severe impact action of the grinding balls on the lining plate of the ball mill, the problems of no wear resistance, easy breakage, unsatisfactory ball carrying effect and the like are solved, the working efficiency is low, the yield is not increased, and the cost is increased invisibly.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides the impact-resistant semi-autogenous mill end lining plate which is simple to manufacture and good in sealing effect.
The purpose of the utility model can be realized by the following technical proposal: a semi-autogenous mill end liner, the end liner is fan-shaped, both sides of the end liner have step surfaces, characterized by that, the end liner includes skeleton and rubber layer to wrap skeleton; the framework comprises a bottom plate, and a reinforcing rib is fixed in the middle of the upper surface of one surface of the bottom plate along the axis direction of the bottom plate; the reinforcing rib comprises two vertical plates which are arranged in parallel, and a plurality of connecting plates are welded between the two vertical plates; a plurality of through holes are formed in the connecting part of each vertical plate and the bottom plate and the connecting plate; a positioning hole is formed in the upper sea of the bottom plate, a plurality of mounting columns are fixedly arranged on one surface of the bottom plate where the reinforcing ribs are located, a supporting plate fixedly connected with the bottom plate is fixed on the circumferential surface of each mounting column, and a threaded hole is formed in each mounting column; the rubber layer covers the reinforcing ribs to form a boss, and the top surface of the boss is a curved surface.
The end plate inside lining of semi-autogenous mill is by a plurality of the utility model provides an end welt and promotion strip concatenation form, and the end welt is fan-shaped, and its both sides all are equipped with the step face, and the step face can be used to install the promotion strip, makes it form the good end plate inside lining of leakproofness. And a steel framework is arranged in the liner plate at the end, and the framework consists of a bottom plate and reinforcing ribs, so that the impact resistance of the liner plate is excellent. A plurality of through holes are formed in the connecting part of each vertical plate and the bottom plate and the connecting plate, so that the rubber layer and the framework are combined more tightly. This end plate middle part forms the boss, and is steel strengthening rib in the boss for its impact resistance is very strong, and it can undertake the impact of partial steel ball, and then better protection promotes the strip, makes whole semi-autogenous mill end plate inside lining life longer. The threaded mounting column is arranged on the end lining plate, so that the splicing and mounting are more convenient and faster.
The utility model has the advantages that:
1. the end lining plate has simple structure and convenient and quick installation.
2. The steel framework is arranged in the end lining plate and consists of a bottom plate and reinforcing ribs, so that the shock resistance of the end lining plate is excellent.
3. In the end liner plate, a plurality of through holes are formed in the connecting part of each vertical plate and the bottom plate and the connecting plate, so that the rubber layer and the framework are combined more tightly.
4. This end plate middle part forms the boss, and is steel strengthening rib in the boss for its impact resistance is very strong, and it can undertake the impact of partial steel ball, and then better protection promotes the strip, makes whole semi-autogenous mill end plate inside lining life longer.
