1, feeding equipment Feeding equipment, conveying equipment and screening equipment are all general equipment, and there is basically no big difference, but we still have to consider the characteristics of the material itself, and pay attention to the humidity, hardness and particle size of the material when selecting equipment, especially the time production requirements.
The new equipment mainly includes electromagnetic vibration feeder, vibrating screen distributor, plate feeder and fluctuating drum feeder. It can not only feed a lot of materials, but also transport soil and materials with high water content. It can be used in the next process of removing natural fine materials, transportation and screening.
2, sand making machine equipment The characteristics of various sand making machines will be different, and their professional knowledge will be different. Commonly used equipment includes impact crusher, cone crusher, jaw crusher, etc. According to the hardness and wear resistance of materials, impact crusher or cone crusher can be selected as medium and fine crushing equipment.
The former is mainly used for crushing materials with low hardness and poor wear resistance such as limestone, concrete, slag and cement blocks, while the latter is mainly used for crushing materials with strong wear resistance such as iron ore, nonferrous metal ore, granite, quartzite, sandstone and pebble. In order to ensure high-quality granular sand, some quarrying equipment will add impact molding sand makers after counterattack or cone crushing.
3. Screening equipment is widely used in the production of machine-made aggregate. Screening equipment mainly includes circular vibrating screen and linear vibrating screen. Among them, circular vibrating screen is widely used in the production of machine-made aggregate. The vibrating screen has adjustable amplitude, long material screening line, multi-layer screens, clear screening of various specifications and high screening efficiency. It is suitable for sand and gravel industry, sand and gravel screening in quarries, and product classification in coal preparation, mineral processing, electric power, building materials, chemical industry and other industries.
4. The dust suppression device and equipment are configured from the perspective of dust prevention, which can effectively control dust escape, reduce the impact of equipment work on the environment, and ensure the cleanliness of the working environment. The overall planning of equipment configuration should minimize dust links and choose equipment with less dust. For the materials transported by belt conveyor, it is necessary to minimize the falling of materials and strengthen the sealing to reduce the escape of dust.
5. The noise of the noise reducer is also very harmful to the sand and gravel factory. Noise prevention and control should focus on the protection of post workers and take comprehensive prevention and control measures. When necessary, the high-noise vibrating screen can reduce the site noise by closing the single building and adding sound insulation materials. There is no fixed post in high noise places, only patrol inspection is carried out. At the same time, the inspectors are equipped with personal protective equipment such as sound-proof earmuffs to reduce the impact of noise on the staff.
