An integrated system and integrated method for auxiliary raw material crushing and pelletizing mineral material screening

Abstract

The invention provides a secondary raw material crushing and pellet mineral material screening and integrating system and integrating method. The integrating system and the integrating method are characterized in that a secondary raw material crushing process and a pellet mineral material screening are integrated on the basis of an existing secondary raw material crushing equipment processing system; the processes are sequentially arranged to realize different material processing functions. The technical processes are simple; the working process switching method is carried out in the same system based on different materials and the change of the properties of the materials, so that the purpose of safe, stable and smooth production and equipment can be achieved. With the adoption of the system and the method, the running rate of existing equipment can be improved; the vacancy rate is decreased; and meanwhile, the equipment investment cost can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of secondary raw material (limestone, dolomite) crushing and pelletizing special material screening, in particular to an integrated system and method for secondary raw material crushing and pelletizing mineral material screening. Background technique [0002] Secondary raw material crushing treatment process The production mode includes the crushing treatment process of limestone and dolomite: the material of the auxiliary raw material limestone crushing treatment system is crushed and closed-loop processed by 3 crushers and screened by 3 vibrating screens; the material of the auxiliary raw material dolomite crushing treatment system After a closed-loop crushing treatment by a crusher and screening by a vibrating screen, it is processed into auxiliary raw materials suitable for sintering and sent to sintering for use. Among them, the undersize of the coarse ore after crushing and screening enters the finishe...
