1. The polyester spiral screw press is putting the filler wire into spiral ring, decreasing the porosity, reducing material which on the surface of the belt loss.

2. Internal parts of belts fill round or tape wire to change the air permeability and density to meet the different needs of industries on sludge dewatering process.

3. Products apply to the food, pharmaceutical, chemical, alcohol, vinegar industry, coal, mining, paper pulp, sludge dewatering and drying industry etc.

4. Products advantages: long service life, the length can be cut according to need; the damaged surface can be repaired, so that the belt can extend service life.

Convenient repair and use, greatly reduces the cost of production. To solve the general mesh waste caused by the problem of inaccurate size.
