Now in order to protect the environment, at the same time can meet the needs of low-carbon environmental protection, some of the mechanism of sand production line is also equipped with auxiliary dust and noise reduction equipment function.
1, feeding equipmentFeeding equipment, conveying equipment and screening equipment are universal equipment, basically no big difference, but we still need to consider the characteristics of the material itself, and pay attention to the humidity of the material, hardness, particle size, especially equipment selection time production requirements and other factors.
With new equipment mainly electromagnetic vibrating feeder, vibrating screen distributor, plate feeder, fluctuating drum feeder and so on. It can not only feed a large amount of material, but also can transport soil and high moisture content materials. It can be used to remove natural fines, transport and screen the next process.
2, sand making equipmentThe characteristics of various types of sand making machine will be different, and its expertise is also different. Commonly used equipment are impact crusher, cone crusher, jaw crusher and so on. According to the hardness and abrasion resistance of the material, impact crusher or cone crusher can be used as medium and fine crushing equipment.
The former is mainly used for crushing materials with low hardness and poor abrasion resistance such as limestone, concrete, slag, cement blocks, etc. The latter is mainly used for crushing materials with strong abrasion resistance such as iron ore, non-ferrous metal ores, granite, quartzite, sandstone and pebbles. In order to ensure high-quality, high-quality granular sand and stone, some quarrying installations also add impact-forming sand maker after impact or cone crushing.
3, screening equipmentWidely used in the production of mechanism sand and gravel screening equipment are mainly circular vibrating screen and linear vibrating screen. The circular vibrating screen is widely used in the production of mechanism sand and gravel. The amplitude of the vibrating screen can be adjusted, the material screen line is very long, there are multi-layer screen, a variety of specifications sieve clear, sieve of high efficiency, applicable to the sand and gravel industry, suitable for quarry screening sand and gravel, but also applicable to coal beneficiation, ore-dressing, electric power, building materials, chemical industry, such as the classification of products.
4, dust reduction deviceEquipment configuration should be from the point of view of dust reduction, can effectively control dust escape, reduce the impact of equipment work on the environment, to ensure a clean working environment. Equipment configuration of the overall program should minimize the dust link, choose less dusty equipment. For materials conveyed by the belt conveyor, should minimize the fall of materials, strengthen sealing to reduce dust escape.
5, noise reduction devicesNoise is also a major hazard in the crushed stone plant. Noise prevention and control should be based on the protection of job workers, to take comprehensive prevention and control measures. If necessary, large noise vibrating screen can be sealed through a single building and increase soundproofing materials to reduce site noise. No fixed positions are not set up in noisy places, and only inspections are carried out. At the same time, the inspectors are equipped with soundproof earmuffs and other personal protective equipment to reduce the impact of noise on workers.
