Description

Wheel grinding device

Technical Field

The utility model relates to a wheel grinding device.

Background

The wet wheel mill is mainly used for crushing (pulverizing) materials with medium hardness (clay, clinker, silica and the like), the medium crushing and fine crushing of the materials are completed through a wheel milling structure according to the needs during use, the materials are placed on a milling disc when the existing wheel milling structure is used, then the materials are crushed through the milling disc, the crushed materials fall through a discharge hole formed in the milling disc, and the materials are collected through a collecting container placed below the milling disc;

on the one hand, when the wheel mill is used for crushing, part of materials are tightly attached to the milling disc after being flattened due to the rolling of the wheel mill, but the materials are not completely crushed and cannot fall through the discharge hole, when the wheel mill is used for rolling the materials again, the effect of the wheel mill on the materials again is affected due to the fact that the materials are tightly attached to the milling disc, and meanwhile, the situation that the discharge hole formed in the milling disc is blocked can occur due to the fact that the materials are not completely crushed; on the other hand, according to different requirements such as middle crushing or fine crushing, the grinding disc of different discharge ports needs to be replaced each time, so as to meet the discharge requirements, but because the grinding disc is large, the labor intensity of a grinding disc replacement person is increased, the replacement efficiency is quite low, in addition, when the grinding disc is worn after long-term use, the whole grinding disc needs to be replaced, because the grinding disc is large, the replacement is inconvenient, and even if the grinding disc only has partial wear, the whole grinding disc needs to be replaced because the grinding disc is a whole piece, and the cost is high; on the other hand, when the grinding wheel rolls, after the material receives the grinding of grinding wheel, partial material can remove like the both sides of grinding wheel to make the grinding wheel unable to roll this material next time, cause crushing effect not good, and when conveying the material, generally all set up the conveyer belt in the grinding dish top, then carry the material to the grinding dish through the conveyer belt, this kind of mode will lead to the concentrated one position of piling up on the grinding dish of material, if the volume is less, the grinding dish can also roll, if the volume of piling up is great after, still need the manual work to roll it after pushing up, still need shut down for the safety reasons when pushing up, not only reduced and roll efficiency and operating personnel's intensity of labour is big.

It is therefore an effort of those skilled in the art to provide a wheel grinding apparatus capable of effectively solving the above-mentioned technical problems.
