Composite internal separating and grinding device of pipe grinder

Abstract

The invention discloses a composite internal separating and grinding device of a pipe grinder. The composite internal separating and grinding device of the pipe grinder is characterized by comprising a round bidirectional flow guide cone, wherein the edge of the bidirectional flow guide cone is peripherally connected with a plurality of internal separating and grinding baffle bin grid plates sequentially; each internal separating and grinding baffle bin grid plate comprises a front grid plate, a rear grid plate, a grid plate support, a flat screen plate and a lifting plate, wherein the front grid plate and the rear grid plate are connected to and fixed on the grid plate support by bolts; a cavity is formed between the front grid plate and the rear grid plate which are arranged on the grid plate support; the lifting plate is arranged in the cavity; the connecting end of the lifting plate is connected to the part close to the center of the grid plate support by a connection bolt; the flat screen plate is welded to a charge end of the rear grid plate; screen seams of the flat screen plate and screen seams of the rear grid plate are longitudinal in direction. The composite internal separating and grinding device of the pipe grinder, which is provided by the invention, overcomes the problems of an existing internal separating and grinding baffle bin device of the pipe grinder at present, and has the characteristics of simple structure design, air ventilation, obvious material transferring effect, modular design, and installation and maintaining convenience.

Description

technical field [0001] The invention relates to a tube mill component, in particular to a composite internal powder selection device of the tube mill. Background technique [0002] Tube mill is a kind of cement machinery used for grinding operation, which is suitable for grinding operation of various materials in the cement production process. The tube mill has the characteristics of strong adaptability to materials, continuous production, large crushing ratio, and easy adjustment of the fineness of the ground product. It is widely used in building materials, metallurgy, mineral processing, electric power and chemical industries to grind cement and other materials. At present, domestic high-fine and high-yield cement mills and slag mills mostly use double-layer internal powder selection compartments, but in actual use, it is found that the existing double-layer internal powder selection compartments have certain disadvantages, such as occupying a large space in the mill. , ...
