Senwei vibration specializing in the production: shaker / straight-line screen / vibration platform 
 Product Description: LS is a trough screw conveyor, the GS is a tubular screw conveyor. 
 The use and characteristics of the screw conveyor 
 L (G), S-type screw conveyor is designed and manufactured in accordance with the JB/T7679-95 "screw conveyor" standard is a new generation product of the GX type screw conveyor. Head and tail bearing moved to the shell, hanging bearing sliding bearings with dust seals, bearing the general use of powder metallurgy, transportation cement adopt blankets bush, hanging axis and screw axis slider connection, disassembly spiral without moving the drive unit, demolition crane bearing without moving spiral, without removing cover lubrication hanging bearings, machine reliability, long life, adaptability, easy installation and maintenance. The screw conveyor is the main industrial and agricultural departments mechanized transport work unit, to enable the transportation work to reduce labor intensity and improve work efficiency, wide range of applications. Applicable to all industries, such as building materials, chemicals, electricity, metallurgy, coal, grain and other industries, horizontal or inclined conveying the temperature of the powder, granular and small lump materials, such as coal, ash, slag, cement, grain and other materials less than 200 ℃. The screw conveyor is not suitable for transportation of perishable viscous, easy caking materials. 
 LS-type screw conveyor Main features: 
 A large carrying capacity, safety and reliability. 
 Adaptability, easy installation and maintenance, long life. 
 Whole volume is small, high speed, to ensure rapid and uniform transportation. 
 4. The discharge end with a cleaning device, machine noise, adaptable, and flexible layout I expected out of position. 
 Good sealing, the shell is made of seamless steel pipe production, the end flange connected to each other into one, and good rigidity. 
 LS-type screw conveyor working principle: 
 The LS-screw conveyor material the use of rotation of the spiral will be transported along a fixed enclosure within the passage of the transportation work, move the head and tail bearings to the shell, the hanging bearing sliding bearings with dust seals, bearings The general use of powder metallurgy, transportation cement bearing blankets, hanging axis and screw axis slider connection.

 The LS-type screw conveyor machine layout in the form: 
 A screw conveyor usually by the spiral machine body, from the device, the drive has three major components. 
 Three kinds of screw machine body from head section, the middle section and tail section. Under normal circumstances, when the factory assembly, the middle section by the length of the length in order of priority, the longest in the middle section near the head section, the middle section of the same length, side by side, if there are special requirements in order to give the order. 
 Thrust bearing in axial force in the first section built, built in the middle section and tail section bearing the screw axis, the length of the axial movement of the radial bearing to compensate for the screw axis in the tail section is also equipped with error and adapt to changes in temperature. Helical surface in the form of entity spiral (S-system method) with screw (D system method) two. Flange coupling between the screw axis, ensure the interchangeability of the connection shaft, ease of maintenance. 
 Cover type for tile and cover the buckle clamped on the case, For improved sealing performance, the user can add a waterproof canvas cover and the chassis between. 
 Into the feed inlet of the feeding device, rectangular discharge port, hand push the discharge port, four kinds of rack discharge port. Openings in the body by the user in the use of site welding. Layout into the discharge port position should be taken to ensure that the discharge port to the end of the distance, while avoiding the gate and the hanging bearing oil cups, casing joint flange and the base collide. 
 ZQ series reducer + Y series motor drive of YTC, gear reducer motor two kinds.
