Product Introduction

Screw conveyor according to the conveying form is divided into shaft screw conveyor and shaftless screw conveyor. According to the appearance, it is divided into U shape screw conveyor and tube type screw conveyor. Shaft screw conveyor is suitable for the non-sticky powder material and small particle material such as cement, fly ash, lime, food, etc.. Shaftless screw conveyor is suitable for conveying sticky and easy-winding materials such as sludge, biomass, litter, fibers, etc.

【Conveying Distance】: ≤30m
【Conveying Capacity】: 100m³/h
【Application Industry】: uitable for various industries such as building materials, chemical industry, electric power, metallurgy, coal mining and food etc.. (For more, please click “Free Consultation”)
【Applicable Materials】: Applicable for conveying powder, granules and small lump materials block in horizontal or oblique such as cement, fly ash, pesticides, titanium dioxide, paint, etc..The material temperature is less than 200 ℃. Screw conveyor is not suitable for transportation of perishable, high viscosity, or easy to agglomerate materials.

    Product Advantages

    High efficiency conveying
    Adopt new hanging type with bearing frame hanging in the middle to increase the delivery space for materials and also reduce the resistance of logistics. Together with small diameter, high rotation speed, changed screw pitch to ensure smooth, fast and uniform feeding.
    Casually arrangement
    The shell is made of high quality seamless steel tube, each section is connected by the flanges and become a whole piece. No matter it is horizontal one or inclined one, it can deliver materials continuously. It can connected and fixed with the auxiliary device and no need for foundation. Taking fully use of space, can be removed and disassembled easily.
    Diversified connection
    Inlet and discharging port can use flange connection, , cloth connection, cloth with derrick connection, universal interface connections, and other forms.
    Reliable sealing
    The joint of casing tube is with the seepage water device, process hole has carefully improved to avoid materials blocked or machine stops due to the cement agglomerate inside the tube resulting in rain infiltration.
    No need to add oil
    With unique intermediate bearing materials, it can reduce friction and also it is anti-abrasive and can self-lubricate, so it is no need to add lubricate even running for a long period. What’s more, it also avoid the side effect on the shaft sleeve and shaft due to the possible mixture of lube and materials.
    Special reducer
    The customized special gear reducer is with advanced design: small in size, light in weight, big in torque, without oil leakage, no noise. And it is with stop-back structure, so it is also suitable for materials delivery when the angle is big.

      Working Principle

      When the screw shaft is rotating, due to the gravity of the material and the friction between the materials and the wall, it makes the material moving forward along the conveyor bottom under the push of the blade. It looks like an un-rotatable nut does translational movement along the rotating screw. The materials movement at the mid bearing is pushed by the moving-forward materials from back. Therefore, the materials delivery inside the conveyor is like a kind of slip movement. To have the screw shaft under better pulled state, normally have the motor and discharging port at same side of the screw conveyor. And have the outlet at the other end of screw. The screw blade push the materials to realize materials-delivery. Because of the materials gravity and also the friction between the materials and shell, the materials will not rotate together with the screw. The screw blade surface type according to the to-be-conveyed materials, it can be: entity type, belt type, and leaf surface type. The screw shaft of the Screw Conveyor is with thrust bearing at the end of the materials moving direction to give the screw shaft reverse force together with the materials. When it is comparatively long, then mid hanging bearing is required.
