Tungsten Carbide Hammer Plate

Introduction

Tungsten hammer plate is the most important and the easiest to wear parts of grinder. Its shape, size, arrangement methods, manufacturing quality, has a great influence on the grinding efficiency and product quality. Currently hammer material for domestic use are mainly low-carbon steel, carbon steel, special cast iron, etc. However, the wear resistance of these materials is much lower than carbide, therefore, the choice of material of cemented carbide as a hammer is already a trend.

Manufacturing Quality

Tungsten carbide hammer plate manufacturing quality is mainly reflected in its material, heat treatment and machining accuracy. Hammer plate is a high-speed moving parts, its manufacturing precision grinder to balance the rotor greatly affected. General requirements for the quality of the rotor hammer any difference between the two groups can not exceed 5g. Therefore, the hammer in the process must be strictly controlled accuracy, especially surfacing tungsten carbide hammer to strictly ensure the quality of welding technology. Hammer factory should be set as a unit. When installation hammer plate sets should be installed every day, freely exchanged between the sleeve and the sleeve is not allowed

Arrangement

Tungsten carbide hammer plate mill rotor on the number and arrangement, affecting the balance of the rotor, crushing chamber materials distribution uniformity hammer wear and efficiency in the mill. Number (hammer density) Hammer Carbide hammer on the number of units to measure the width of the rotor, the rotor density is too large, the starting torque, the material hit more often, lower production of electricity; the density is too small, crushed production machine will be affected.
Tungsten carbide hammer plate arrangement refers to the relative positional relationship between the groups on the rotor hammer and hammer between the same groups. Hammer arrangement best meet the following requirements: the rotor rotates, the trajectory of each hammer will not be repeated; the material does not occur to smash the indoor side offset phenomenon (except for special requirements) in the passage of the hammer; rotor force balance, no vibration during high-speed operation.
