An automatic crushing equipment for the production of sulfate-resistant cement

Abstract

The invention discloses an automatic crushing equipment for the production of sulfate-resistant cement. The automatic crushing equipment for the production of sulfate-resistant cement comprises a frame, a rotary hammer assembly, and an impact plate assembly. Material inlet, below the material inlet is a semi-cylindrical and hollowed-out discharge cage, in which a plurality of rotary hammer assemblies are coaxially arranged, and adjacent rotary hammer assemblies pass through the main shaft In series, one end of the main shaft is connected to one side of the frame through a bearing, and the other end is connected to the frame through a power-receiving axial assembly; an impact plate assembly is provided on the side above the rotary hammer assembly that is staggered from the feed port; A bead is provided below the impact plate assembly, and the bead is spaced a certain distance from the edge of the rotary hammer assembly. Compared with the prior art, the present invention is suitable for feeding different materials to ensure the stable shape of the discharge.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to an automatic crushing equipment for the production of sulfate-resistant cement. Background technique [0002] Sulfate-resistant cement is made of portland cement clinker with appropriate composition, adding appropriate amount of gypsum, and grinding to make a hydraulic cementitious material that resists sulfate ion erosion, called sulfate cement. In the cement production process, most of the raw materials are crushed, such as limestone, clay, iron ore and coal. Good crushing effect facilitates the homogenization of materials, improves the uniformity of materials, reduces the strength of grinding materials, increases the output of mills, increases the surface area of ​​materials, and improves drying efficiency. Therefore, the crushing of raw materials is an important step in cement production. layout. [0003] There are many kinds of raw materials used in cement produ...

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of raw materials used in cement production, and there are also different requirements for crushing equipment. For example, limestone ore is generally more than 1m in size. The particle size of the grinding can be larger, which is 70mm. Therefore, the crushing ratio of the crusher is required to be greater than 40, while the diameter and density of the coal are much smaller. If the same crushing equipment is used, the output will be uneven, and in the subsequent Easy to heat unevenly during firing
