Automatic crushing equipment used for production of sulphate-resistant cement

Abstract

The invention discloses automatic crushing equipment used for production of sulphate-resistant cement. The automatic crushing equipment used for production of the sulphate-resistant cement comprises a rack, rotating hammer assemblies and an impact plate assembly, wherein a feeding opening is formed in the upper portion of the rack, a semi-cylindrical hollowed-out discharging cage is below the feeding opening, the multiple rotating hammer assemblies are arranged in the discharging cage and coaxial with the discharging cage, the adjacent rotating hammer assemblies are connected in a staggered mode through a spindle in series, one end of the spindle is connected with one side of the rack through a bearing, and the other end of the spindle is connected with the rack through a power-receiving axial assembly; the impact plate assembly is arranged at the side, away from the feeding opening, above the rotating hammer assemblies; and a batten is arranged below the impact plate assembly, and the batten and an edge of each rotating hammer assembly are at a certain distance. Compared with the prior art, the automatic crushing equipment used for production of the sulphate-resistant cement is suitable for putting of different materials so that a stable discharging shape can be ensured.

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
