Background

The screw conveyer is a machine which utilizes a motor to drive a screw to rotate and push materials so as to realize the conveying purpose. The conveying device can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross section area, good sealing property, convenience in operation, easiness in maintenance, convenience in closed transportation and the like. The spiral conveyor is divided into a shaft spiral conveyor and a shaftless spiral conveyor in the conveying form, and is divided into a U-shaped spiral conveyor and a tubular spiral conveyor in the appearance. The spiral conveyer with shaft is suitable for dry powder material and small particle material without viscosity. (e.g., cement, fly ash, lime, grain, etc.) and shaftless screw conveyors are suitable for conveyors made of viscous and windable materials. The working principle of the screw conveyer (such as sludge, biomass, garbage and the like) is that a rotating screw blade pushes materials to convey the materials by the screw conveyer, and the force which prevents the materials from rotating together with the screw conveyer blade is the self weight of the materials and the frictional resistance of a shell of the screw conveyer to the materials.

Therefore, the device for measuring the abrasion loss and the coaxiality of the screw shaft is improved.
