Introduction.

Screw Throat Pipes are an important component in MDF/HDF wood panel plant. The plug screw feeder feeds chips continuously into a pressurized vessels above the refiner mill.

The plug screw feeder compresses the chips to:

1. Remove pitch, water and remaining air, without shortening fiber length

2. The highly compressed chips are discharged into the impregnator visa a blow-back piston.

3. The pressate is recycled back to the chip wash to maximize pulp yield

4. The screw is wasy to operate and needs very little maintenance.

The features of High wear resistant Screw Throat Pipes for Defibrators:

1. Casted by premium high alloy material, with surface hardening treatment and excellent wear resistance.

2. Optimize the design of structure to decrease the possibility of Block.

3. Optimize the reduction rate, ensure the dehydration.

4. High hardness up to 50-60HRC

5. No need to repair during performance, saving cost and increase production efficiency. \

Material

Currently we supply materials Cr13 for the Screw Throat Pipes according the drawings. By the heat treatment, we can get a better wear resistant for the Screw Throat Pipes.
