Description

Pulverizer

The present invention relates to a pulverizer, and more particularly, to a pulverizer capable of obtaining a powder having a constant particle size in a short time by performing the pulverization and separation of the raw materials such as food, chemicals, minerals, etc. at the same time.

In general, the pulverizer pulverizes the raw material into a predetermined particle state, and it is possible to obtain powder pulverized into desired particles by receiving various kinds of granular raw materials from the hopper.

In other words, the grinder is a device for crushing raw materials such as food, chemicals, minerals, etc. It is divided into hammer type and knife type. In particular, the device using the rotary hammer has a high speed rotating hammer to prevent the impact of the raw material from colliding with the raw material and friction with the liner. It is structured to finely crush the raw material, and the pulverized powder is dropped into the lower screen net, small particles fall through the screen net, and the large particle powder is configured to be caught.

However, the above-mentioned conventional pulverizer is formed of a flat liner, the grinding efficiency is lowered when the hammer hits, and the hammer and the liner is formed of ordinary cast iron, so wear occurs easily when performing the grinding operation for a long time .

Referring to the working relationship for the crusher according to the present invention configured as described above are as follows.

9 is a view showing the working relationship of the crusher according to the present invention, a view showing a state in which the raw material is pulverized in the crushing unit, Figure 10 is a view showing the working relationship according to the invention, a state in which air and powder in the cyclone is separated Figure is shown.

As shown in the drawing, the grinder 100 according to the present invention firstly operates the first, second and third motors 222, 238, 318 and the suction pen 518 in the state of the raw material supply unit 310. When the raw material is put into the hopper 312 is moved by the screw shaft 316 is supplied to the inside of the crushing container 210.

In this way, the raw material supplied to the pulverization cylinder 210 is hit by the raw material while the first shredding blade 220b rotates by the rotation of the first housing 220 to the concave-convex 216a formed inside the liner 216. As the friction occurs, the raw materials are crushed.

At this time, the raw material is pulverized by the rotation of the first housing 220 and the outside air is supplied through the air supply pipe 410 by the centrifugal force and the suction pen 518, and is supplied to the inside of the grinding cylinder 210 The compressed air is moved to the body 232 of the separator 230 as the pulverized powder.
