Novel rice milling emery roll

Abstract

The invention provides a novel rice milling emery roll which comprises an emery roll body and a metal core sleeve which is embedded in an inner hole of the emery roll body. The novel rice milling emery roll is characterized in that the emery roll body is a special-shaped body composed of a square part and an arc-shaped part, the horizontal plane of the arc-shaped part is connected to the square part, the out-protruding surface of the arc-shaped part points outwards, and long-strip-shaped air spraying holes are respectively formed in two sides of the protruding arc-shaped part. The novel rice milling emery roll is simple in structure, low in manufacturing cost and good in machining quality, can reduce energy consumption and can be widely used in the rice milling industry.

Description

technical field [0001] The invention relates to a rice milling emery roller used in a rice milling machine, in particular to a novel rice milling emery roller. Background technique [0002] Rice milling emery roller is an important accessory for milling and finishing grain in rice milling machine. Existing emery roller mainly contains ceramic rice milling emery roller and resin rice milling emery roller. Ceramic sand rollers are made of silicate raw materials such as clay and feldspar as binders and abrasives, which are dried, roughly machined, and sintered at high temperature. They have long production cycles, high firing temperatures, and high energy consumption. The emery roller is prone to cracks and deformations during manufacturing, the scrap rate is high, and the geometric dimension accuracy is low. Due to the poor molding performance of the binder, the emery roller is brittle. The emery roller needs to maintain a large wall thickness and consume more raw materials. ...

AI Technical Summary

Problems solved by technology

Ceramic sand rollers are made of clay, feldspar and other silicate raw materials as binders mixed with abrasives, dried, roughly machined, and sintered at high temperature. The emery roller is prone to cracks and deformations during manufacturing, the scrap rate is high, and the geometric dimension accuracy is low. Due to the poor forming performance of the binder, the emery roller is brittle. The emery roller needs to maintain a large wall thickness and consume more raw materials. , and it is difficult to open hole grooves and thread grooves on the emery roller, and it is inconvenient to process and install

Resin sanding rollers generally have low toughness and poor impact resistance. They wear out too quickly during use and their service life is too short.

In addition, the existing emery rollers are all cylindrical, with large volume, heavy weight, and high production cost; moreover, the dynamic balance and vibration are large during use; the required current is large, and the energy consumption is high; Small area, high rice temperature
