Grinding material
Grinding tooth design appropriate choice to achieve the established parameters of the beating, but also must have good wear resistance and impact toughness. Throughout 100 years, grinding manufacture, and use in development worldwide, stone, gray iron, nickel, hard white iron, high chrome cast iron, nickel-chromium alloy, multi-alloy, stainless steel, tungsten carbide, high molecular weight polyethylene , modified nylon, ceramics, silicon carbide and other materials have been obtained using, in view of wear resistance and economic considerations, the current multi-alloy and high chrome cast iron grinding grinding because of good wear resistance in a dominant position. Multi-alloy sheet having a surface grinding coarse fibers tend to better the role of sub-wire broom; grinding steel fibers tend to cut more intense effect.
Selection of grinding
Multi-alloy grinding four series:
Cutting fin series:
Suitable partial free like beating, lower power consumption state quickly reduce long-fiber wet weight, which will help improve the evenness.
Soft fin series:
Suitable for short-fiber pulp species, cutting effect is weak, keeping the fiber length, which will help reduce the loss of wet weight.
Ease fin series:
Suitable for succulent species, and ease the pumping ability, lower power consumption, which will help increase the rate.
Broom fin series:
Suitable for partial viscous beating, fiber sub-wire broom is stronger, which will help to enhance the degree of beating.
Our abrasives progress
Before and after the reform and opening up:
Our abrasives and to the world, in the following aspects were investigated or improved
① improve precision grinding machines;
② improve the grinding degree of automation;
③ high speed grinding;
④ precision and high finish;
⑤ heavy grinding;
⑥ wide and multi-wheel grinding wheel;
⑦ grinding machine to improve productivity;
⑧ trial developed special grinding or profile grinding;
⑨ superhard abrasives.
Superhard materials such as synthetic diamond and cubic boron nitride, now known as the world's hardest substance, Mohs hardness of 10.
