Fly Ash Enclosed Chain Conveyor Mining Powder Cement Ash Scraping Chain Machine, Classification and Structural Features: (1) The spiral blades of the screw conveyor come in three types: solid spiral surface type, belt spiral surface type, and blade spiral surface type. The solid spiral surface is called the S method, with a spiral pitch of 0.8 times the blade diameter for the GX type, and the LS type screw conveyor is suitable for conveying powdered and granular materials. The belt spiral surface is also known as the D method, with a spiral pitch equal to the diameter of the spiral blade, suitable for conveying powdered and small lump materials. The blade spiral surface is less commonly used, mainly for conveying highly viscous and compressible materials, and it also performs mixing and blending processes during conveyance, with a spiral pitch approximately 1.2 times the blade diameter. (2) The spiral blades of the screw conveyor come in left-hand and right-hand rotations. (3) Types of screw conveyors include horizontal fixed screw conveyors and vertical screw conveyors. The horizontal fixed screw conveyor is the most commonly used type. The vertical screw conveyor is used for short-distance lifting of materials, with a conveying height generally not exceeding 8m, and it uses a solid surface spiral blade. It must be fed by a horizontal screw to ensure the necessary feed pressure. (4) At the material outlet end of the LS and GX type screw conveyors, a 1/2 to 1 loop reverse spiral blade should be installed to prevent powder blockage at the end. (5) The screw conveyor consists of three parts: the screw body, the inlet and outlet ports, and the drive unit. The screw body is composed of the head bearing, tail bearing, hanger bearing, screw, casing, cover plate, and base. The drive unit consists of an electric motor, reducer, coupling, and base.

The rotational speed of the spiral body in a vertical screw conveyor is higher than that of a standard screw conveyor. The added material, under centrifugal force, generates friction with the casing. This friction prevents the material from rotating with the spiral blade and overcomes the gravity of the descending material, thereby achieving vertical conveyance. This machine has a small conveying capacity, limited conveying height, high rotational speed, and high energy consumption. It is particularly suitable for conveying... From the perspective of material displacement direction, screw conveyors are divided into two main types: horizontal screw conveyors and vertical screw conveyors. Screw conveyors with conveying chains made of high-strength plastic are also known as food screw conveyors or spiral elevators, mainly used for conveying large items such as cartons, turnover boxes, and bottled water. Depending on the characteristics of the conveyed materials and structural requirements, screw conveyors include horizontal screw conveyors, vertical screw conveyors, flexible screw conveyors, and spiral tube (roller conveyor) conveyors.
