Embodiment Construction
[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] Aiming at the relatively low operation rate of material handling in auxiliary raw material crushing equipment system, it is unavoidable, while the pelletizing mineral material processing system in the raw material branch plant is relatively tense. If the pelletizing ore processing equipment fails, it will have a serious impact on the supply of...

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...
