A schematic diagram of the pulverizer (mill) is shown in Figure 1. The pulverized material is input through the input port 7. The fine powder crushed by the rotation of the ball 3 is pushed out to the surroundings and blown upward by the pressurized air flow in the air nozzle 9.
The fine powder is further separated in a separator and discharged, accompanied by air. Coarse powder falls by gravity and is crushed again by the ball to become fine powder. In this process, the pulverized material at the air nozzle is constricted into a nozzle shape to increase the flow velocity in order to create the high-speed airflow necessary to blow it up. Conventional E-mills are standard with slit-like notches and holes. In the EM mill, the grooves in the nozzle block served as airflow paths. The opening areas of these holes and grooves were adjusted through trial runs to ensure a constant flow rate. In addition, since the amount of air needs to be adjusted according to the load on the mill, the flow rate of the air passing through this nozzle may fluctuate, and the crushed material from the nozzle may fall and remain inside the mill, causing problems with operation. be.

A finely pulverized product (mill) will be explained using the schematic diagram of FIG. 1 as an example. For rotating the mill ball,
A grinding ball 3 is rotated on a driving reducer 1 by rotation of a rotating yoke 2. In order to prevent the balls from floating up, pressure is applied by the upper ring 4 to increase the crushing effect. The crushed material is inputted from the input port 7, falls onto the rotating yoke 2, is pushed out to the outer periphery, and is crushed and crushed by the balls 3. On the other hand, high-pressure air is blown into the lower part of the yoke 2 from the primary air duct 13 and blown up as a high-speed air stream from the air nozzle 9 placed outside the rotating yoke 2. The incoming fine particles are carried away by the air flow and are discharged. The coarse particles separated by the separator fall again inside the ball, are crushed into fine powder by the ball, are blown up again from the air nozzle part, and are discharged as fine powder while circulating.

することができる。 When the mill load changes, the primary air amount also changes, but when the air amount decreases, the flow velocity of the air nozzle decreases, and particles may fall from the nozzle and accumulate at the bottom of the mill. In order to solve these problems, the air nozzle drive cylinder 12 is actuated by a signal from a flow meter 14 attached to the primary air duct 13, and the actuation cylinder 11, which connects each nozzle on the circumference, is connected to the air nozzle via the actuation lever 10. 9 and adjust the gap between the nozzles as shown in Figure 3.
Adjust from L 1 to L 2 to change the opening area,
The flow velocity can be secured as an opening degree commensurate with the measured amount of air.

分離効果を上げることができる。
Since the nozzle plate is tilted, the airflow becomes a tangential rotational flow, which becomes a consistent flow from the airflow inside the mill to the inflow direction of the separator, which can improve the separation effect of fine powder.
