Grinding device

Abstract

The invention discloses a material milling device which comprises stone mills, wherein a barrel opening of a milling barrel is upward; a vertical main rotating shaft is connected with the stone mills through flatly arranged stone mill shafts; rolling milling fit is formed between the roll surfaces of the stone mills and an inner barrel bottom of the milling barrel; a material discharging opening is formed in the inner barrel bottom of the milling barrel, and a gate plate is arranged corresponding to the material discharging opening; a material conveying pipe and a straw pulp pool which are communicated with each other are correspondingly arranged below the material discharging opening; and a water injection pipe extending into the material conveying pipe is arranged below the material discharging opening. Straws capable of being milled conveniently can be transferred to the straw pulp pool in time for next pulping procedure, so that the steps of manually transferring the straws back and forth and adding water for pulping in a pulping procedure are eliminated, and the labor intensity of a worker is reduced.

Description

Technical field [0001] The invention belongs to the technical field of rice paper manufacturing, and particularly relates to a material grinding device. Background technique [0002] As the raw material for making rice paper, singe grass is made of rice straw (shatian rice straw in Jingxian County). Handmade paper made of rice straw is rice paper. Straw from other regions can also be used as raw material to make handmade paper, but it usually does not have the traditional meaning. The quality of rice paper) is used as raw material, processed by special traditional technology to remove lignin and other impurities in the rice straw for making rice paper. In the specific production process, the singe grass is chopped and dusted by the horn dust collector. After being poured with water according to the humidity required by the process, it is transferred to the stone milling room. The process requirements before crushing: a. Servings are 60-65%; b. Stacking time: ≥18 hours; c. Grass ...

Problems solved by technology

In the prior art, the plan for further crushing the above-mentioned liaocao is to use a stone mill to roll on the pan. During the rolling process of the stone mill, the liaocao is quickly pushed to the two ends of the stone mill, and the liaocao at the edge of the pan It is very easy to fall from the grinding plate, and it is necessary to manually collect the grass on the side to make it continue to be rolled. The grass that is crushed in the above-mentioned rolling process and looks like slag is then transferred to the grass pulp pool The pulp is then further prepared, and its transfer process is also labor-intensive
