Brief introduction:
The classify of screw conveyer: tubular and U type screw conveyer, tubular screw conveyer is with perfect sealing effect,especially used for Strict sealing requirements,such as smelly materials or very thin materials,

he classify of screw conveyer: tubular and U type screw conveyer,tubular screw conveyer is with perfect sealing effect,especially used for Strict sealing requirements,such as smelly materials or very thin materials or according to practical condition of site. tubular screw conveyer can transport material with  lean,but it is inconvenient to observe the inside materials and the clean up.

Utype conveyer is convenient to observe the inside materials and the clean up.

Our choose should be based on materials, throughput, oblique Angle, Conveying length and so on.
Consult our salesman and Customized for you,Customized can save more than 20% of the cost for you,you can get more satisfactory products

U type screw conveyer

 U type screw conveyer is manufactured by the DIN15261-1986 strict standard，Its design is according to JB/T7679-2008 screw conveyor professional standards，U type screw conveyer is widely used in food, chemical industry, building materials, metallurgy, mining, power and other departments，it mainly used for conveying  small granular, powder, small block material。It is not suitable for transporting perishable material, and the material with larger caking viscosity and larger water content.
the classify for U type screw conveyer

Driving method
1、
Its length is less than 35 m, It is a single shaft drive screw
2、
Its length is more than 35 m, It is double-shaft drive screw

classify by rolling hanging bearing
1、
MI is rolling hanging bearing, using 80000 type sealed bearing, Shaft cover is with dust seal structure,it is widely used for difficult to add oil and oilless, it has perfect sealing effect ,and the hanging bearing is with long service life, Conveying material temperature is ≤80℃

2、
M2 is sliding hanging bearing,it is with dust seal device, it has  Castingcopper tile, wear resistant complex alloy cast iron tile, Copper matrix graphite less oil lubrication tile,,It is widely used for transporting materials in high temperature （t≥80℃）and high water-content

classify by the material of screw conveyer
1、
U type screw conveyer with ordinary carbon steel is mostly used for the industry that No special requirements for material ,such as cement, coal, stone.
2、
stainless steel U type screw conveyer is mostly used for special requiments industry ,such as transporting food, chemical, food, it has high cleanliness ,no pollution for materials and long service life,but the price is a little high.

The characteristics and the reference of the equipment

U type screw conveyer is Suitable for small lscale operations,its transportation is stable,it can  is work well in Limited transportation field,it is a great advantage for the occasion that large dust or for working conditions with requiments,it can avoid dust .But U type screw conveyer is not suitable for long distance transportation, It is high cost and easy to cause the extrusion and destruction for friable material
