Material milling 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 manufacture, in particular to a grinding device. Background technique [0002] As a raw material for making rice paper, Liaocao is handmade paper made from rice straw in Shatian (Shatian rice straw in Jingxian County). Rice straw in other areas can also be used as raw material to make handmade paper, but it usually does not have traditional sense. The quality of rice paper) is used as raw material, which is processed by special traditional techniques to remove impurities such as lignin in rice straw for making rice paper. In the specific production process, the liaocao is chopped and dusted by a claw dust collector, and then wetted with water according to the humidity required by the process, and then transferred to the stone mill. The process requirements before crushing: a. The portion is 60-65%; b. Stacking time: ≥18 hours; c. The length of grass slices: 20-40mm. In the prior art, the plan...

AI Technical Summary

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
