Abstract
The invention discloses a high-speed pulverizer, wherein during pulverizing, materials enter from a feeding pipe and are fed onto a rotary device through a chute, and the materials are repeatedly crushed, dropped, milled, dropped again and milled again under the combined action of high-speed rotation of the rotary device and a lining plate. Meanwhile, under the action of the fan in the discharge pipe, the finely-divided materials are taken away by wind power, and the particle materials continuously fall down, so that the process is repeated for many times. The coarse material falling to the bottom is collected into a lifter through a discharge passage and enters the device again for crushing and grinding; when the fine powder taken away by the fan passes through the separator, the finished product material is taken away by wind and enters a collector for collection; the thicker material falls down and enters the crushing and grinding process together with the newly-fed material. The high-speed pulverizer disclosed by the invention has the advantages that the energy consumption is reduced, the structure is simplified, the operation and later maintenance are convenient for operators, the occupied area is reduced, and the productivity is improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in FIG. 1, a high-speed pulverizer comprises a base 1, a middle shell 2, a revolving device, an upper support 3, a separator 4 and a transmission device 5;
a bearing seat is arranged in the base 1; a bearing is arranged in the bearing seat, and a rotating device is connected above the bearing; the upper part of the slewing device is connected with another bearing, and the bearing is fixed in a bearing seat at the central position of the upper support 3; a belt 6 wheel is arranged in the base 1, the belt wheel is connected with a transmission device 5 through a belt 6, and the transmission device 5 drives a rotating device to do rotating motion between an upper bearing and a lower bearing; a hammer plate is arranged on a main shaft of the slewing device, a hammer head is arranged on the hammer plate, and the hammer head rotates along with the rotation of the slewing device;
the upper part of the base 1 is connected with the middle shell 2 and the upper support 3 through bolts in sequence; the base 1, the middle shell 2 and the upper support 3 enclose the rotating device in a closed space; an air passing hole is formed above the upper support 3 and communicated with the separator 4;
a feeding pipe 7 is arranged on the side wall of the separator 4, and the feeding pipe 7 is communicated with the inside of the middle shell 2 through a chute; a discharge pipe 8 is arranged at the top of the separator 4, and one section of the discharge pipe 8 is communicated with the air passing hole of the upper support 3; the other end of the discharge pipe 8 is connected with a collector; a fan is arranged on the other side of the collector;
a funnel-shaped discharge passage 9 is connected below the base 1; the discharge duct 9 is connected to the inlet of a hoist whose outlet is connected to the inlet of the feed pipe 7.
A lining plate is arranged inside the middle shell 2.
When the material is ground, the material enters from a feeding pipe 7 arranged on the side surface of the separator 4 and is fed to a rotary device in the middle shell 2 through a chute, and the material is crushed, falls, is ground, falls again and then falls again under the combined action of a high-speed rotary hammer head arranged on the rotary device and a lining plate arranged on the middle shell 2. Meanwhile, under the action of the fan in the discharge pipe 8, the fine crushed materials are taken away by wind power, and the particle materials continuously fall down, so that the process is repeated for many times. The coarse materials falling to the bottom are collected into a lifter through a discharge passage 9 and enter the device again for crushing and grinding; when the fine powder taken away by the fan passes through the separator 4, the finished product material is taken away by the wind by adjusting the rotating speed of the rotor of the separator 4 to adjust the fineness and enters a collector for collection; the thicker material falls down and enters the crushing and grinding process together with the newly-fed material.
