UHMWPE Screw Conveyor Trough Liners

Screw conveyor trough liners enhance the performance and service life of a screw conveyor. Liners improve efficiency when conveying very free-flowing or fluidizing bulk materials on steep inclines by reducing the clearance between the screw and housing. Liners also provide a low friction surface to reduce adhesion when conveying sticky bulk materials. Trough liners also act as a bearing surface when intermediate hanger bearings are eliminated in conveyors using close-coupled and clocked or shaftless screws. Most commonly, trough liners provide a wear surface to increase the longevity of the trough or housing.

Selection of the appropriate liner material and attachment method is critical to ensuring a low maintenance screw conveyor. KWS utilizes extensive experience and an application database when selecting trough liner materials for a specific application. We have developed a secure liner attachment method that simplifies installation and replacement. As we are not limited to proprietary or own-brand liners, we review the requirements in an unbiased and commercially efficient way to ensure the best match for the job.


Material & Advantages of screw conveyor liners

UHMW – Engineered plastic with low coefficient of friction. Relatively slow wear for most applications where bulk material conveyed has some liquid or sticky properties.

1、   耐磨性居塑料之冠,比尼龙66和聚四氟乙烯高4倍,比碳钢高6倍;Abrasion resistance at the top in plastics, 4 times higher than nylon 66 and PTFE, 6 times higher than carbon steel; 

2、冲击强度列塑料之首,为PC的2倍,ABS的5倍,且能在液氮温度(-196℃)下保持高韧性; The impact strength ranks first among plastics, which is 2 times of PC and 5 times of ABS, and can keep high toughness at liquid nitrogen temperature (-196)

3、自润滑性与聚四氟乙烯相当,摩擦系数仅为0.07-0.11; Its self-lubrication is approach to that of PTFE, and the coefficient of friction is only 0.07-0.11

4、冲击能吸收值在所有塑料中为最高值,消音效果很好; The impact absorption value is the highest among all plastics, and the sound attenuation effect is very good

5、化学稳定性很高,在一定温度和浓度范围内能耐各种腐蚀介质及有机介质的作用; High chemical stability, in a certain temperature and concentration range can withstand the action of various corrosive media and organic media

6、抗粘附能力极强,仅次于聚四氟乙烯; Strong anti-adhesion ability, second only to PTFE;                                                                                                             

7、完全卫生无毒,可用于接触食品和药品; Completely hygienic and non-toxic, can be used to contact food and medicine

8、耐腐蚀性能优越,摩擦系数低,比重小,良好的抗高能量辐射性能.

Excellent corrosion resistance, low friction coefficient, small specific gravity, good high energy radiation resistance
