Problems solved by technology
In the process of realizing this application, the applicant found that the powder spraying phenomenon will occur after the material enters the feed port, but reducing the tuyere will reduce the working efficiency of the pulverizer
[0004] At the same time, due to the action of high-pressure air in the feed air channel, the wall of the air channel is severely worn, and the wall of the air channel needs to be replaced frequently, resulting in an increase in production costs

The invention discloses a wear-resistant volute feeding machine base which comprises a machine base body. The machine base body is provided with a feeding bin and multiple feeding air flues; the feeding bin is located in the middle of the machine base body and is coaxial to the machine base body; the multiple feeding air flues are spirally arranged on the machine base body along the axis of the feeding bin and communicate with the feeding bin; each feeding air flue is provided with an inner wall and an outer wall arranged oppositely; the inner walls and the outer walls are in arc shapes; included angles between one side end parts, far away from the feeding bin, of the inner walls and the outer walls and the radial direction of the feeding bin ranges from 15 to 20 degrees; tangent planes are arranged on one side end parts, adjacent to the feeding bin, of the inner walls; and the thickness of each tangent plane ranges from 50 to 60mm. According to the wear-resistant volute feeding machine base provided by the invention, an included angle of the outer side edge of an existing feeding air flue relative to the axis of the feeding bin is reduced, so that the area of a feeding outlet is reduced, the occurrence of the phenomenon that materials are sprayed from a tuyere can be reduced, and the working efficiency of the device cannot be reduced.
Description
technical field [0001] The application relates to the technical field of pulverizers, in particular to a wear-resistant volute feeding machine base. Background technique [0002] Grinding machine is commonly used grinding equipment, mainly used for barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock , gypsum, glass, bluestone, petroleum coke, chemical raw material insulation materials and other non-flammable and explosive minerals, chemicals, construction and other industries with a Mohs hardness not greater than 9.3 and a humidity below 6%. powder processing. [0003] The existing pulverizer is mainly composed of a main engine, an analyzer, a blower, a finished product cyclone separator, a pipeline device, a motor, etc.; during the use of the pulverizer, the material enters the silo from the air inlet of the machine base, and then is discharged by the grinding ro...
