Description

But quick detection and breaker is with welt and breaker of change

Technical Field

The utility model relates to a lining plate for a crusher, in particular to a lining plate for a crusher capable of being rapidly detected and replaced and a crusher.

Background

As an important device for mining, a crusher crushes raw ores of different sizes into particles of different sizes by means of extrusion, bending and the like. The method is widely applied to various departments such as mine, smelting, building materials, highways, railways, water conservancy and chemical industry and the like.

Along with the rapid development of the economy in China, the national green and environment-friendly sustainable development strategy proposes that the crushing equipment used in the mines in China is increasingly large. After equipment is enlarged, the equipment is limited by site conditions and equipment, and easy-damaged parts are difficult to replace and the time is too long, so that the production stopping time is too long, and the equipment becomes one of pain points of ore production enterprises.

A gyratory crusher is a large crushing machine for crushing ores or rocks with various hardness by utilizing the gyratory motion of a crushing cone in a cone cavity in a shell to generate extrusion, splitting and bending actions on materials. The crushing process is completed between fixed cone lining board and rotary moving cone lining board as the cone crusher. The dynamic cone lining plate and the fixed cone lining plate are main abrasion spare parts. After 3-4 months of continuous production, the product should be replaced. If the efficiency of replacing the lining plate can be improved, the operation cost of ore production enterprises can be greatly reduced.

The current common lining board installation scheme is as follows: epoxy resin or zinc layer is directly poured behind the movable cone lining board and the fixed cone lining board and is used for fixing the lining board, and no cutting hole is formed behind the lining board. This solution has the obvious disadvantage: firstly, whether the lining plate reaches the service life can not be judged in time, and only the ore discharge port can be continuously reduced until the maximum adjustment value is reached, the lining plate can be confirmed to be replaced, and the fixed cone lining plate or the movable cone lining plate can not be confirmed specifically. And secondly, the disassembly is difficult. Taking a medium model gyratory crusher as an example, 2 days are required for disassembling the fixed cone lining plate in a mode of combining hydraulic hammer knocking with flame cutting on site, and 2 days are required for disassembling the movable cone lining plate.
