The invention improves the control accuracy of the roll gap, and has the advantages of simple operation and labor saving.

Description

technical field [0001] The invention relates to the technical field of wet grinding equipment, in particular to a sand disk starch mill, which is suitable for processing grain materials such as rice, soybeans, corn, and potatoes. Background technique [0002] The sand disc starch mill equipment mainly relies on the relative rotation of two sand discs to grind the feed into powder. [0003] The existing sand disc starch mill, as disclosed in Chinese patent document CN201379038Y, is mainly composed of a feed hopper, a grinding part, a discharge hopper, an intermediate seat, a base and an electric motor, wherein the grinding part includes a grinding cylinder, a grinding cover, The upper sand tray and the lower sand tray, the upper sand tray is formed by bonding the upper sand sheet to the upper iron tray, and the lower sand tray is formed by bonding the lower sand sheet to the lower iron tray. The upper sand disc is fixed on the movable coil, and the upper and lower positions ...

AI Technical Summary

Problems solved by technology

The sand table adjustment adopts the lifting method of the movable coil of the upper sand table. Due to the large structure of the upper sand table, the structure of the movable coil is also relatively large. In actual operation, the operation is laborious due to the lack of a transmission mechanism, and the overall structure is large. The manufacturing cost is high; the adjustment mechanism is placed on the upper part, which is easily affected by the upper hopper, the space is limited, and the upper structure is poor in cleanliness, insufficient lubrication, easy to be damaged, and the service life is reduced; the abrasive in the design of the grinding cylinder is directly from the lower part Discharge, there is no fixed discharge port, it is difficult to receive materials, the cost of manpower or supporting equipment is increased, and the labor intensity is high; and the assembly of the whole mechanism is relatively difficult
