Screw conveyor of simple structure, small cross section size, good seal, reliable operation, low manufacturing cost, convenience of intermediate loading and unloading, transportation direction can reverse, can also be transmitted at the same time two opposite direction.But also for material in the process of conveying stirring, mixing, heating and cooling operations, through the loading and unloading valve can adjust the material flow;But unfavorable transport of perishable, big viscosity, easy to agglomerate and chunks of material;Material is easy broken, in the process of conveying screw rotation and chute is easy to wear;Unit power is larger;Used to keep the material in the tank sealing and have adequate clearance between screw and feeding trough.
