Milling line is suitable for grinding processing of mineral materials such as metallurgy, building materials, chemicals, and mines. It can be used for feldspar, calcite, talc, barite, fluorspar, rare earth, marble, ceramics, bauxite, manganese ore, phosphorus Ore, iron oxide red, quartz sand, cement clinker, activated carbon, clay, gangue, gypsum, silicon carbide, refractories, etc. Non-inflammable and explosive mineral material powders with a Mohs hardness below 8 and a humidity of less than 6% Processing. Raymond Mill has a huge role in the milling production line. The whole pipeline system of Raymond Mill should be operated under negative pressure to prevent dusting in the workshop, but before and after the system does not want negative pressure too much or too much. small. If it is too large, the air leakage is large. If it is too small, temporary partial pressure may be caused. Therefore, reduce the resistance of the pipe as much as possible. At the same time, we must rationally arrange the entire pipeline of the mill and the humidification tower so that the resistance can be balanced and balanced. According to the example, the requirement of adjusting the air volume can be achieved by adjusting the door. However, in order to adjust it more timely, the wind distribution is more reliable, and the valve is set. The purpose of placing the valve behind the humidification tower is to lower the valve requirement after cooling.
Yuhong Heavy Industries believes that the waste heat utilization pipeline belongs to the production pipeline and must meet the requirements of long-term production. The layout should be compact and smooth, avoid sharp turns to reduce resistance. Up and down the pipeline as much as possible more than 45 degrees, can not be level, set the ash doors and compressed air cleaning pipes in place. Valves require flexible, reliable operation and minimize air leakage. The valve should be protected from internal dust to ensure smooth opening and closing. The conventional waste heat utilization process in which the kiln exhaust gas enters the valve of the mill pipe, and the valve of the exhaust fan duct of the mill can use the electric remote control butterfly valve. The butterfly valve has a large internal leakage and a low air leakage. In normal production, the valve is open and there is no problem of internal leakage. The purpose of setting the valve is to separate the entire grinding system when the mill is stopped. Since the exhaust gas has a certain temperature, the valve should be designed to prevent deformation as much as possible, so it should have a sufficient thickness.
Raymond Mill exhaust fan selection must meet the needs of the system air volume, resistance, and each 15% reserve. The head backup and air volume are consistent because the backup wind does not necessarily enter the system from the grinding head, so the resistance does not equal the square of the backup air volume.
