Abstract

The invention discloses a five-double full-dry method crushing production line and processing method for high-quality sand aggregates. The production line comprises a material pretreatment system. A discharge port of the material pretreatment system is connected with a feed port of double-impact crushing equipment of a fine coarse aggregate processing system, a discharge port of the material pretreatment system is connected with a primary classifier, and a discharge port of the primary classifier is connected with a finished product screening and proportion adjusting circulation system. A super-particle-size material outlet of the finished product screening and proportion adjusting circulation system is circularly connected to a feed inlet of double-speed double-frequency crushing sand making equipment. The fine sand aggregates are connected to corresponding finished product bins or are circularly connected to the feed inlet of the double-speed double-frequency crushing sand making equipment, and multi-stage powder selecting equipment is arranged below a fine sand outlet. According to the production line, the production line with multi-stage desliming, double-countering-impact crushing, double-vertical-shaft impact crushing shaping sand making, multi-stage powder selecting and multi-stage circulation is adopted, so that the system productivity and the quality of the finished sand aggregates are improved effectively, the efficient and energy-saving effects are realized, and the practicability is high.

Description

technical field

[0001] The invention relates to a high-quality sand and gravel aggregate five-double full-dry crushing production line and a processing method, which belong to the technical field of sand-making production equipment and sand-making production technology. Background technique

[0002] At present, in the production of sand and gravel aggregates, the traditional sand and gravel aggregate production line usually uses rod feeders to feed materials evenly, and uses coarse crushing jaw crushers, medium crushing cone crushers or impact crushers for crushing to complete raw material pretreatment, and then The pretreated material enters the vertical shaft crusher for crushing, and enters the screening system for screening. The qualified products enter the finished product warehouse through the finished product belt conveyor, and the oversized materials are transported back to the vertical shaft crusher for mechanical crushing through the return belt conveyor. This conve...
