Abstract
The grinder consists of abradant and adhesive. Compared with available grinder of iron and steel material, the said one has the merits of low cost, long service life and high pulp making efficiency. As part of paper-making pulper, it is used for pulp making in paper and fiberboard making.
Description
The present invention relates to a kind of papermaking (fibre-bearing plate) pulping machinery parts, particularly a kind of grinding tool that is used to grind paper pulp.
At present, the grinding tool on the paper-making pulper regardless of its shape size, all is iron and steel material qualities, is generally wear resistant cast iron, spheroidal graphite cast-iron or cast steel.The shortcoming of the grinding tool of this material is, manufacturing cost is higher, and anti-wear performance is poor, and slurrying efficient is low, and therefore, people are seeking a kind of grinding tool that high-wear resistance and alternative material with low cost are made that has always.
The purpose of this invention is to provide a kind of papermaking that anti-wear performance is good, cost is low, efficient is high (fibre-bearing plate) pulper grinding tool that has.
The object of the present invention is achieved like this: the making material of pulper grinding tool is made up of abrasive material and bond.
Purpose of the present invention can also following manner realize: said abrasive material can be brown corundum, white fused alumina, carborundum, single alundum, pink fused alumina.
Said bond can be vitrified bond, resinoid bond, gum cement.
The present invention has following advantage: with the contrast of iron and steel material quality grinding tool, cost per unit can save 15%, and can prolong 15% service life, because the coefficient of friction of grinding tool of the present invention increases, can improve more than 5% so slurrying efficient is about simultaneously.
Elaborate below in conjunction with embodiment:
Embodiment one: select brown corundum in granules material to make abrasive material, vitrified bond is made bond, produces new material grinding tool of the present invention by the existing grinding tool shape of various model paper-making pulpers.
The palm fibre corundum: the color sepia, the hardness height, toughness is big, is commonly used for the grinding tool material in the metal manufacturing grinding process.
Vitrified bond: a kind of inorganic bonding agent is that the raw material cooperation makes by clay, feldspar and other natural alumino-silicate materials.This bond applied range, stable performance is not subjected to weather, influence of temperature variation, can be water-fast, heat-resisting and never degenerate.
Embodiment two, select carborundum (black silicon carbide or green silicon carbide) to make abrasive material, and gum cement is made bond and produced new material grinding tool of the present invention by the existing grinding tool geomery of various model paper-making pulpers.
Black silicon carbide: color black, also have to be navy blue, have smooth surface and glassy lustre, its crystallization physical efficiency is glittering.Its hardness ratio corundum is that abrasive material is all high, but toughness is lower, green silicon carbide: color is the edge look, the same black silicon carbide of outward appearance, and hardness ratio fragility is more taller than black silicon carbide.
Gum cement: a kind of organic bond is that major ingredient makes with natural rubber or artificial rubber.Its feature is the intensity height, and is flexible.
Above abrasive material and bond are formed can be referring to " grinding tool selection " book (the first grinding materials and grinding tool grinding research institute of Ministry of Machine-Building Industry, publication is write by second grinding wheel factory, in May, 1969)
The manufacturing technique of grinding tool does not have specific (special) requirements, and its abrasive species, granularity, bond kind are selected all can require to select according to different slurrying.Process for making: abrasive material and bond mix, and put into mould inner pressure and make type, drying, loading of kiln is fired, and finishing is finished product behind the kiln discharge.
