GX and LS screw conveyors (hereinafter referred to as screw conveyors) adopt international standard products, equivalent to IS01050-75 standard. The design and manufacture meet the professional standards of JB/T7679-1995 "Screw Conveyor". The structure is novel, the technical indicators are advanced, the head and tail bearings are moved to the outside of the shell; the middle hanging bearing adopts two structures that can be used for rolling and sliding. Both are equipped with dust-proof sealing devices. The seals are made of nylon and plastic, with low resistance. Strong sealing and good wear resistance. The sliding tile has cast copper tiles that need lubricant, alloy wear-resistant cast iron tiles and copper-based graphite oil-less lubrication tiles. The discharge end is equipped with a cleaning device. The whole machine has low noise and adaptability. Strong, convenient operation and maintenance, flexible layout of the feeding and discharging position. According to the needs of users, a broken shaft alarm device can be additionally equipped. The screw machine has been widely used in various sectors of the national economy, such as building materials, metallurgy, chemical industry, electric power, coal, machinery, light industry, grain and food industries, suitable for conveying powder, granular and small lump materials, such as cement and coal. Powder, grain, fertilizer, ash, sand, coke, etc. It is not suitable to transport materials that are perishable, viscous, and easy to agglomerate. The working environment temperature of LS screw conveyor is usually -20-40℃, and the temperature of conveying materials is generally -20-80℃. LS screw conveyor is suitable for level and small The inclination angle should not exceed 150. If you have special requirements, you can negotiate with the manufacturer for special design and manufacture.
