Embodiment 1

[0026] Embodiment 1: The present invention is a (single) double-disk grinding disc for papermaking, which overcomes the shortcomings of steel grinding discs in the refining process.

[0027] The feature of the present invention is that the "composite material" possesses the necessary strength, wear resistance and friction coefficient of the grinding disc, which is higher than that of steel, and its main feature is that a large number of micro-shaped sharp teeth are gathered on the surface of the grinding disc. Even if the sharp teeth on the surface are worn out, new sharp teeth are added. The size and quantity of these "sharp teeth" can be adjusted according to different beating requirements. The number of sharp teeth is large, the particles are large, and the cutting ability of the grinding plate is strong, which is suitable for the high cutting requirements of hemp and cotton fibers; the number of sharp teeth is small, the particles are small, and the cutting ability of the ...

Abstract

The invention relates to an abrasive disc for papermaking, which is applied to the beating technology in the paper production process. The abrasive disc for papermaking consists of the following raw materials in parts by weight: 15-50 parts of base material, 15-65 parts of fiber material and 16-65 parts of abrasion-proof material, wherein the particle size of the abrasion-proof material is 50-500 meshes; the base material, the fiber material and the abrasion-proof material have a wetting and splicing effect; and the base material has abrasion resistance and toughness. The abrasive disc provided by the invention has the advantages of reasonable formula design, light weight, low energy consumption, low manufacturing cost, controllable beating quality and stable quality.

Description

technical field [0001] The invention relates to a grinding disc for papermaking, which is used for the beating process in paper production engineering. Background technique [0002] The role of beating in the papermaking process is very important. The same fiber raw material, using different beating methods, the performance of the produced paper can be quite different. Pulping is also a high-energy-consuming process. The entire papermaking process consumes hundreds to thousands of degrees per ton of paper, and beating accounts for about half of it, of which 70-80% is power consumption by disc grinding. [0003] Beating Equipment Except for a very few mills that still use trough beaters due to special needs, most paper mills have used disc mills (single disc mills, double (three) disc mills) for beating. Whether it is a trough beater or a single or double disc grinder, steel knives are basically used for beating, and only a few factories use other materials, such as stone k...
