Screw conveyor GX, LS screw conveyor (hereinafter referred to as spiral machine) is the use of international standard products, equivalent to ISO1050-75 standards. Designed and manufactured in line with JB / T7679-1995 "screw conveyor" professional standards. New structure, advanced technical indicators, head, tail bearing housing to move outside; middle hanging bearing rolling, sliding two interchangeable structure, are located dust seals, seals with nylon and plastic king, low resistance, sealing strong, good wear resistance, sliding tile has to be added lubricant bronze tiles, tile and copper-based alloy cast iron graphite tiles less oil lubrication, cleaning device has a discharge end, low-noise and adaptability Strong, easy operation and maintenance, feeding and discharging position flexible layout. According to user needs, can reprovision the broken shaft alarm device. Screw machine has been widely used in various sectors of the national economy, such as building materials, metallurgy, chemical, electric power, coal, machinery, light industry, food and food industries, suitable for conveying powder, granular, small block materials, such as cement, coal flour, grain, fertilizer, ash, sand, coke. Not transport perishable viscous, easy caking materials, LS screw conveyor operating ambient temperature is usually -20 ~ 40 ℃, the temperature of transported material is generally -20 ~ 80 ℃, LS screw conveyor appropriate level and small inclination layout, not to exceed 15 ° inclination is appropriate, if there are special requirements, in consultation with the manufacturer, for special design and manufacturing. Screw Conveyors are two: U-type and tube. The main technical parameters: screw diameter (mm) throughput
