Description

Grain Grinder {pulverizer for cereal}

The present invention relates to a grain grinder, and more particularly, to an apparatus for milling various grains with a plurality of grinding rollers to obtain fine powder.

In general, a conventional grain grinder is composed of a hopper for inputting grains, a grinding roller for crushing the input grains, and an outlet. When the grains are introduced into the hopper, the grain is crushed by two crushing rollers engaged with each other. It is discharged through an outlet located at.

However, in order to obtain fine powder with the grain grinder, there are a method of repeating the process several times, and a method of pulverizing by putting into a grinder composed of a helical gear and a flat roller.

However, the above methods have the disadvantage of having to grind the grind again and having a plurality of grinders.

Accordingly, the present invention has been made to solve the above problems,

When grain is put into the hopper, it is sequentially crushed by the main roller of the grinding chamber divided into 1 and 2 chambers and a number of helical gears and flat rollers in close contact with each other. It would be.

In addition, a large number of helical gears and flat rollers are located on the outer circumferential surface of the large main roller, so that the grinding by the gear and the grinding by press are alternately performed, thereby reducing the number of devices and increasing the utilization of the working space. In providing a grinder.
