Description
Technical Field
The utility model relates to a grind ore equipment technical field, concretely relates to compound grid plate of double-deck wear-resisting metal rubber for mill.
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 full/semi-autogenous mills and ball mills) are integrally cast and molded by steel, and are provided with elongated grid holes, when ores are ground to be smaller than the width of the grid holes, the ores pass through the grid holes, enter a dustpan plate and are discharged out of the mill.
However, the existing grid plate is limited by a heat treatment process, the situation that the grid plate is not quenched completely and the hardness difference between the surface layer and the core part is large easily occurs, and in the using process, the grid plate has the risk of being broken by the impact of ores and is poor in wear resistance and short in service life.
