The particle size range of the screened materials is adjusted by controlling the distance between the roll gaps and the number of the rolls, the lower part of the roll type screening feeding machine is connected with the discharging scraper so that the screened fine materials and the fine materials directly fall onto the belt conveyor, the material hopper below the roll type screening feeding machine is manufactured into a whole with the scraper discharging scraper, the material flushing noise of the screening hopper is reduced by adopting a thick steel plate, and meanwhile, the flat steel is welded to form an aggregate layer to prevent abrasion.
The pre-screening crushing system of the utility model, after pre-screening treatment, the fine powder and the fine crushed aggregates do not need to enter into the crusher again to increase the load of the crusher and easily cause the blockage phenomenon of the crusher, effectively solves the above problems and simultaneously ensures that the massive materials are more fully crushed to form crushed finished products with proper crushing ratio, thereby greatly improving the efficiency of the crushing link;
the crushing system collects and transports scattered fine crushed materials and screened materials at two times and conveys the materials to the belt conveyor from the same hopper, so that the overall utilization rate of raw materials is improved for the whole crushing system, and the load of the crusher is greatly reduced;
the plate feeder head cover, the roller type screening feeding machine guide plate and the crusher head cover integrated dustproof shell meet the environmental protection requirement, meanwhile, the recycling efficiency of fine materials is enhanced, the returned ash can directly form finished products to participate in a grinding link, and the guarantee of the capacity of the whole cement production line is helped. Thereby playing the great role of reducing energy consumption and saving cost.
