Vertical airflow sieve overview
Dahan manufacturers is a fine powder screening machinery factory. With the development of market economy and technology, product quality and fineness of various powder materials, precision increasingly demanding. Fine powder material easy to adhere to, small size, light weight, easy suspension characteristics; existing domestic vibration sieve, sieve using its gravitational potential linear exciting force, elastic work hard to screening, it can lead dust, and more difficult to meet the technical requirements. Han's response to this situation, engineers and technicians trial after years of research, developed specifically for fine powder screening of the latest products - air sieve.
80-530 mesh sieve with a network of various powder materials screening classification, its high screening efficiency, large output, automatic feed nesting, continuous operation, no pollution, making it difficult in the past with a variety of high-shaker fine degree of precision screening operations become easy. After light calcium on 120-180 mesh, 300 mesh TSP, 400 mesh active calcium, hawthorn 300 mesh powder, zinc powder 320-500 mesh, 500 mesh black iron oxide, iron oxide red, 120-160 mesh in powder, 180- sieved using a 270 mesh quartz powder materials, the measured output per hour per square meter screen area were about a ton, while the measured screening efficiency above 95%, air dust content of less than 10mg / m3.
Use:
To properly install the screen, the machine into a cylindrical mesh installed on the screen, the lower end of the rope were fixed. Screen lap joints bonded with adhesive 810, lap width of about 30-50mm. Fixed at both ends of the rope, crimping edges align the screen, so the screen does not distort, not to fight Zou, uniform tension. When there is network test screen, the first feed rate adjustment is small, gradually increase the feed rate.
Air sifter unit operation start-up sequence: induced draft fan air flow sieve → → discharge auger.
Stop order: draft fan airflow sieve → → discharge auger.
Baghouse dust collection bag should be promptly jitter, typically once per hour to beat or shake.
Maintenance:
Requires the operator according to the product specification, the proper use of equipment, make clean, lubrication, tightening and anti-corrosion and other routine maintenance work equipment, the equipment inside and outside keep clean, good performance, safe and reliable state.
Electrical control box should be kept clean to prevent dust falling into the control box, causing a short circuit failure or electric elements.
Host, motor and fan maintenance once a year, adding a small amount of lubricating oil, remove the motor inside the dust.
Exciter must be repaired once or twice a year, each service must add oil, connecting bolts to be tightened.
Replacing the screen to follow the requirements of the first part of the operation, to ensure uniform tension, fixed at both ends of the rope fastened while adjusting the screen edge.
