leak-free filtration of polymer melts

Matched with extruders of different specification, applicable to process with most polymers.

New sealed compensation screen changer

 

The new sealed compensation screen changer, or as is called, the plate screen changer, is widely used for the production of various plastics and chemical fibers. It is of high performance/price ratio, and ensures the screen changing without machine halt, or any material leakage under high pressure. Therefore, it is especially applicable to large scale machines of film blowing, pipe making, plate making and granulating, etc.

Performance characteristics

1. Automatically compensates the sealed surface clearance (self-owned patent), high-pressure resistant, high-temperature resistant, and no material leakage. Contain screens of large filtering area, especially appropriate for high yield production line under high pressure.

2. No need to stop the working machine when changing the screen, easy to operate and maintain, reliable for higher production output and lower energy consumption, 80%-90% down of waste material caused by screen changing.

3. Simple construction, reliable operation; Easy maintenance, lower running cost; Automatic screen changing by hydraulic; Machine non-stopped with screen changing.

 Application fields

Applicable to the production of various thermoplastic, chemical fiber, rubber, collosols, adhesive, coating and finishing materials alike, mainly used for filtration of the material mixture.

Commissioning

At the requirement of customer, seller should send technicians to install and debug the screen changer to the die at site of Buyers, Travelling expenses and accommodation fee should be borne by Buyers.

Warranty service

The product's warranty date is one year. According to the contract technical parameters shall prevail, accord with the actual requirement.

After service

Replace of the spare parts in warranty date, the freight is paid by the buyer.
