Introduction:
Plug screw feeders of the type which utilize a rotatable feed screw are utilized in pulp manufacturing processes. Such processes involve feeding lignocellulosic material, such as wood chips, wood shavings and sawdust, or various non-wood fibers, such as sugarcane bagasse, from a hopper or storage container equipped with the screw feeder to further processing equipment. This further processing equipment can include mechanical refiners or disk refiners, as well as digesters and other pulp treatment devices, such as impregnating equipment.
Screw feeders are disclosed including a conical feed screw rotatably disposed in a conical screw tube, and a drive shaft mounted at one end of the conical feed screw with a pair of bearings mounting the drive shaft, a fixed ring mounted on the drive shaft, and an axially adjustable sleeve mounted on the drive shaft, with the pair of bearings disposed between the fixed ring and the axially adjustable sleeve in order for the pair of bearings to be pre-tensioned therebetween.
Manufacturing Process:
Characteristics:
1. Cast by premium stainless material, with surface hardening treatment and excellent wear resistance.
2. Optimize the design of the structure to decrease the possibility of Block.
3. Optimize the reduction rate, ensure the dehydration.
