Modified limestone powder dry grinding and screening equipment

Abstract

The invention relates to the technical field of limestone, and discloses modified limestone powder dry grinding and screening equipment. The equipment comprises a base, wherein the upper end of the base is movably connected with a dry grinding mechanism; the dry grinding mechanism comprises a shaft pipe; the shaft pipe is rotationally sleeved with an iron screen drum; the lower end of the shaft pipe is rotationally connected with a grinding roller extending to the inner wall of the iron screen drum; the position, at the upper end of the shaft pipe, of the front side of the iron screen drum is fixedly connected with a material box; and the front end of the iron screen drum is fixedly connected with a gear ring. According to the modified limestone powder dry grinding and screening equipment, the grinding roller is designed at the bottom of an inner cavity of the iron screen drum, an E-shaped rod is matched, the shaft pipe located at the upper side of the grinding roller is used for intermittent feeding, a convex half gear is used for driving the gear ring to rotate intermittently, an intermittent compression mechanism of a compression joint bag is matched, and then a knocking rod can knock the top of the iron screen drum intermittently, so that materials blocking sieve holes are vibrated off in time, the overall processing effect of the equipment is effectively improved, and the screening efficiency of the materials is guaranteed.

Description

technical field [0001] The invention relates to the technical field of limestone, in particular to a modified limestone powder dry grinding and screening equipment. Background technique [0002] At present, after crushing the modified limestone, the obtained limestone powder needs to be dry-grinded and sieved again. However, during the use of the general modified limestone powder dry-milled and sieved equipment, the material is sent into the equipment in large quantities. If dry grinding and screening are carried out internally, the workload of the equipment running at the same time will be large, which will make the dry grinding and screening effect worse, and the processing of large quantities of materials will cause direct force between materials and between materials and equipment mechanisms. It will lead to an increase in the probability of the filter mechanism being blocked, so that the screening efficiency of the material is reduced. [0003] Aiming at the deficienci...

[0002] At present, after crushing the modified limestone, the obtained limestone powder needs to be dry-grinded and sieved again. However, during the use of the general modified limestone powder dry-milled and sieved equipment, the material is sent into the equipment in large quantities. If dry grinding and screening are carried out internally, the workload of the equipment running at the same time will be large, which will make the dry grinding and screening effect worse, and the processing of large quantities of materials will cause direct force between materials and between materials and equipment mechanisms. It will lead to an increase in the probability of filter blockage, so that the screening efficiency of materials will be reduced

[0003] Aiming at the deficiencies of the prior art, the present invention provides a modified limestone powder dry grinding and screening equipment, which has the advantages of effectively improving the overall processing effect of the equipment, effectively ensuring the screening efficiency of materials, and solving the general problem of During the use of modified limestone powder dry grinding and screening equipment, there are problems such as poor overall processing effect of the equipment and low screening efficiency of materials.
