[0001] A MILLSTONE SYSTEM FOR CRUSHER [0002]

The present invention relates to a grinding mill for grinding mills such as rice, soybean, sesame and the like by means of upper and lower millstones. In particular, an upper fixed millstone and a lower rotating millstone are assembled in a simple structure without insert molding, The present invention relates to a grinding mill system for grinding mill which can improve the grinding efficiency and the discharge efficiency of grain by improving the shape of the millstone and installing a rotary screw.

In general, a grinder has been disclosed in various forms by finely pulverizing grains such as rice, soybean, sesame and the like. Recently, a mill-type grinder for grinding using the principle of millstone has been disclosed.

The present applicant has been registered with a number of applications of a mill-type crusher, such as the registered utility model No. 20-0449241, by simplifying the structure of the millstone system and its assembling structure of the fixed millstone and the rotating millstone, In addition to enhancing the grinding efficiency, it also prevents foreign matter and garbage from accumulating and is easy to clean, so that the sanitary condition is kept clean.

In particular, the grinding system of the grinder has a grooved grinding surface formed to be inclined downwardly from the center to the outer periphery and formed concentrically with a recessed and recessed ring, and a lower milled grinding surface formed below the grooved grinded grinding surface; The upper millstone is provided with a protruding inclined machining surface which is inclined upwards from the outer periphery toward the center and which is formed in a concentric circular shape and has a constant diameter and which is accommodated in the grooved inclined machining surface of the upper mill body and an upper inclined machining surface And three rotating grooves formed on the projection type oblique machining surface in such a manner that three discharge grooves and an oblique erosion protrusion are protruded in a radial pattern at intervals of 120 degrees.

In this mill system, grains put between a grooved sloped surface of a fixed millstone and a rotating millstone and a surface of a sloped surface are guided in the rotational direction while the grain is crushed by three grinding protrusions due to high speed rotation of the bottom millstone, As a result, frictional grinding is carried out by the grooves between the grooved grooved grooved surfaces and the projected grooved grooved grooves, and the fine grooved grains are discharged through the three grooved grooves, So that they can be discharged by rotary centrifugal force through the gap.

However, the above-mentioned line registration technique of the present applicant has the following problems.

First, the disassembly and assembly of the fixed millstone and the rotating millstone are easy, but only the fixed millstone and the rotating millstone can not be disassembled and assembled, and the insert-molded resin structure is disassembled and assembled together with the fixed millstone and the rotatable- And the cleaning management of the washing machine was limited.

That is, there has been a problem that it is difficult to sanitize the millstone because the mill stone is boiled in water or sterilized by high-temperature steam to perform hygienic treatment.

Secondly, the grain does not flow well between the fixed mill and the rotating mill, and in particular, in the case of wet grains, the grains adhere to the grain inflow path and do not flow in more easily. Therefore, the grinding efficiency is lowered and the load of the driving motor is increased, there was.

Third, since the pulverized material pulverized by the fixed millstone and the rotating millstone can not be smoothly discharged through the discharge port in the pulverizing chamber, there is a great inconvenience in that the pulverized material must be discharged manually after the pulverizing operation.

Fourth, since the fixed mill and the rotating mill are merely grinding the grain by the crushing protrusion, they are guided in the centrifugal direction in the narrow gap between the grooved inclined crushing surface and the convex inclined crushing surface, and are crushed by the friction caused by the inter- In order to comprehensively crush dry grains and wet grains, the grinding efficiency is lowered and the grinding time is long. In addition, there is a problem that the finely milled grains are stagnant between the fixed millstone and the rotating millstone and are not smoothly discharged.
