Description

Grid plate with working surface of pure rubber structure for mill

Technical Field

The utility model relates to a grind ore equipment technical field, concretely relates to working face is grid plate for mill of pure rubber structure.

Background

The autogenous mill is a new ore grinding equipment with two functions of crushing and grinding. The grinding machine is named as an autogenous grinding machine because the ground materials are used as media and are crushed through mutual impact and grinding action. The semi-autogenous mill adds a small amount of steel balls into the autogenous mill, so that the processing capacity can be improved by 10-30%, the energy consumption of unit product can be reduced by 10-20%, but the abrasion of the lining plate is relatively increased by 15%, and the fineness of the product is also thickened. Both of them are widely used in the technical field of ore grinding.

Most of grid plates used in the existing mills (including autogenous mills and semi-autogenous mills) are integrally cast and molded by steel, and are provided with elongated discharge holes, when ores are ground to be smaller than the width of the discharge holes, the ores pass through the discharge holes and enter a dustpan plate to be discharged out of the mill.

However, the discharge hole of the steel grid plate is easy to deform, so that the problems of ball blocking, material blocking and the like are caused, the production efficiency is greatly influenced, and the service life of the grid plate is influenced.
