Description
Technical field:
the invention relates to a stone production system, in particular to a sand and aggregate crushing and screening production system, and belongs to the technical field of stone production.
The background technology is as follows:
the existing sand and aggregate crushing and screening production system comprises a feeding crushing system, a screening system, a sand making production system, a dust removing system and a loading system, wherein each system is mutually independent, the occupied area is large, the stone production cost is high, and certain problems and defects exist in each system.
The existing stone production, feeding and crushing system generally adopts a large stone material to be fed into a jaw crusher through a vibrating feeder for primary coarse crushing, and the stone material after primary coarse crushing is fed into a counterattack crusher for secondary fine crushing through a belt conveyor; the stone materials after being finely crushed by the impact crusher are sent to a vibrating screen by a belt conveyor for screening, stones with different particle size specifications are screened out, and stones meeting the particle size requirements are sent to a finished product material pile by a finished product belt conveyor; the stones which do not meet the particle size requirement are returned by the belt conveyor to the impact crusher for crushing again, so that closed-loop multiple circulation is formed. In the prior art, a vibration feeder is used as raw material for conveying a stone production system, and because the feeding capacity of the vibration feeder is limited, the processing capacity of a single crusher is limited, and a plurality of production lines are required to be designed to meet the yield. The occupied area is large, and most of the materials are produced in open air, so that the environmental protection requirement is not met. The impact crusher used in the prior art is a secondary crushing device, and is used for crushing stone returned materials which cannot meet the particle size requirement after being classified by a screening system, and the particle size composition of the stone after being coarsely crushed by the jaw crusher is different from the particle size composition of the stone after being finely crushed by the impact crusher and returned materials which cannot meet the particle size requirement after being classified by the screening system, wherein the particle size of the stone crushed by the primary jaw crusher is generally 150-300 mm, and the particle size of the stone crushed and reshaped by the secondary impact crusher is generally 50-150 mm; and the impact crusher with the same technical parameters cannot effectively exert the equipment performance, and meanwhile, the production capacity of the production line is influenced.
The existing stone production screening classification system generally adopts 1 to 3 layers of vibrating screens to screen out stones with 1 to 4 particle sizes, generally stones with particle sizes of 20 to 30 mm, 10 to 20 mm, 5 to 10 mm and 0 to 5 mm, have fewer particle size types and can not meet market demands. In order to meet the requirement of stones with more particle sizes, the whole production line is generally required to be rebuilt, so that the occupied area is large, the equipment is repeatedly put into, and the existing equipment cannot be effectively utilized. In the actual production process, because the particle sizes of stones are greatly different, the required vibrating screen has different performances, and when stones with large particle sizes are screened, the required vibrating screen has large amplitude and low frequency; when stones with small particle size are screened, the vibration sieve is required to have small amplitude and high frequency; the screening area required for screening large-particle-size stones and small-particle-size stones is also different. In the prior art, stones with larger grain sizes are screened by the same 1 vibrating screen, so that the performance of the vibrating screen cannot be effectively exerted, the actual processing capacity of a single vibrating screen is generally smaller, and a plurality of vibrating screens are commonly arranged in parallel to meet the production capacity and the production efficiency, so that great waste is caused.
In the machine-made sand production system in the prior art, stone with the grain size smaller than 50 mm is generally adopted to enter a sand making machine for crushing, stone crushed by the sand making machine enters a vibrating screen for screening, stone with the grain size smaller than 4.75 mm enters a powder selecting machine for selecting powder, finished sand meeting the grading requirement enters a finished sand bin, ash powder not meeting the grading requirement enters an ash powder bin, and stone with the grain size larger than 4.75 mm enters the sand making machine for crushing again. And meanwhile, dust is collected at the transfer point and the vibrating screen by using a dust remover. The machine-made sand production system in the prior art has the defects of more transfer equipment, large occupied area and unstable quality of finished sand because the quantity of raw materials entering the sand making machine cannot be automatically controlled according to the size of the return material quantity (stone material larger than 4.75 mm) of the vibrating screen.
The existing gate feeder and loading belt conveyor under the finished product bin are used for carrying out dust collection by adopting a dust remover installed on or near the loading belt conveyor, and the collected dust is directly or through a scraper machine unloaded into the loading belt conveyor, so that the quality of finished products of stones is seriously affected, and secondary dust is generated.
The existing stone production finished product stone storage bin usually adopts 1 to 8 finished product stone bins, namely stone with the particle size of 45 to 80 mm, 20 to 30 mm, 10 to 20 mm, 5 to 10 mm, 3 to 5 mm and 0 to 3 mm and machine-made finished product sand, and the general finished product bins are often arranged in a line and occupy larger area. The loading system generally adopts a loading channel arranged under a finished product bin, and loads the finished product by a lower gate of the finished product bin and a bulk machine, so that loading operators and automobile drivers are required to cooperate in the loading process, and faults such as stone overflowing a carriage and the like are often caused in the loading process of the finished product stone. Because each finished product bin is provided with a loading channel, namely, each loading channel can only load one finished product stone, but often, the finished product stone with the grain size of 20-30 mm needs to be loaded with the finished product stone with the grain size of 10-20 mm by the passing grading loading, the finished product stone with the grain size of 5-10 mm needs to be loaded with the finished product stone with the grain size of 10-20 mm by the passing grading loading, and the finished product stone with the grain size of 10-20 mm needs to be loaded with the vehicle for multiple times and transferred to the loading channel under the corresponding finished product bin to finish the grading loading, so that the loading speed is slow, the efficiency is low, more operators are needed, and the cost is high.
The invention comprises the following steps:
the technical problems to be solved by the invention are as follows: the sand aggregate crushing and screening production system has the advantages that the equipment utilization rate is high, the occupied area is small, the sand aggregate production system can be built firstly, the sand production system can be built later according to the requirement, and the sand production system is relatively independent and is economical and applicable.
