Problems solved by technology

[0002] The grinding fineness of the grinding pulverizer in the prior art is mainly controlled by adjusting the grinding time and vibration force. Different coal types have different settings for grinding time and vibration force. However, even if the grinding time is longer for some samples, the vibration force No matter how big it is, the sieving rate can only reach 80-90%

Abstract

The invention discloses a grinding type pulverizer which comprises a grinding device, a drive device and a screen assembly. The grinding type pulverizer is additionally provided with the screen assembly, the screen assembly comprises a base communicating with a discharge outlet, an upper cover matched with the base and a screen arranged between the base and the upper cover, and the upper cover communicates with a vacuum suction device through a pipeline. Vacuumizing operation is carried out on a cavity through the vacuum suction device, negative pressure is formed in the cavity, samples in thegrinding device are sucked, the samples enter the base at first and then pass through the screen, the samples meeting the screening requirement pass through the screen to enter the upper cover and are pumped away by the vacuum suction device, the samples not meeting the screening requirement are left on the base and enter the grinding device again for grinding till meeting the screening requirement, and afterwards the samples pass through the screen and are pumped away by the vacuum suction device. By means of the grinding type pulverizer provided by the invention, the samples entering the vacuum suction device can completely meet the screening requirement, and the sample screening rate is effectively increased.

Description

technical field [0001] The invention relates to the technical field of material grinding, in particular to a grinding type pulverizer. Background technique [0002] The grinding fineness of the grinding pulverizer in the prior art is mainly controlled by adjusting the grinding time and vibration force. Different coal types have different settings for grinding time and vibration force. However, even if the grinding time is longer for some samples, the vibration force No matter how big it is, the sieving rate can only reach 80-90%. [0003] Therefore, how to improve the sieving rate of samples has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a grinding pulverizer to improve the sieving rate of samples. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A grinding mill comprising: [0007] A grind...
