Of course, there was a problem that the grinding performance is greatly reduced.

Second, productivity is increased when the grinding operation is performed step by step using a plurality of grinders, but space utilization is greatly reduced because the space for arranging a plurality of grinders must be secured, and the initial purchase as well as the maintenance of a plurality of grinders are maintained. The disadvantage is that the cost burden of management increases.

Third, since a pair of rollers installed in the grinder interlock with each other through gears, the rotational ratio cannot be adjusted, which leads to cumbersome closing of the particle size by adjusting the distance between the rollers.

The present invention has been devised to solve the above problems, and more particularly, to provide a compact grinder having a compact structure, excellent in space utilization and low incidence of failure, and in particular, easy to control the size of the crushed particles of the pulverized product. do.

In order to achieve this object, a feature of the present invention is a pair of grinding rollers (10) which are provided to be driven independently by each drive motor (14) whose speed is controlled by an inverter (12); Upper and lower hoppers 20 and 20 ′ which are installed at upper and lower parts of the grinding roller 10 to guide the discharge of the pulverized product, and the internal space is divided by the diaphragm 22; And vertical screws 30 installed at one end of the upper and lower hoppers 20 and 20 'to be transferred to the other upper hopper 20 adjacent to the pulverized product discharged to the lower hopper 20'. It characterized in that it comprises a.

At this time, any one of the pair of grinding rollers 10 is characterized in that the screw rod 16 and the handle 18 is provided at both ends to adjust the spacing.

In addition, the diaphragm 22 is characterized in that one end is provided with a guide plate (22a) to accommodate the front end of the vertical screw (30).
