China Precision Continuous Laser Filter Technology for Efficient Filtration Factory and Manufacturers

Continuous Laser filter

The automatic melt filters of the PTC series are suitable for materials with up to 5% by weight contamination and are guaranteed to remain in use for long periods without changing the filter. Our PTC melt filters are capable of processing a wide range of polymers (e.g. PE, PP, PS, ABS, HDPE). All solid or elastomer foreign particles such as paper，wood, aluminum, copper, rubber, silicone, or high-melting polymer composites are efficiently removed. The filter screen is made from composite material with proper hardness drilling by CNC laser machine of cutting-edge technology. PTC filter is a fully automatic continuous operation machine controlled by integrated PLC; Supporting our customer through the saving of labor cost, material losses, energy and increase your profit margin! PTC melt filters can in principle be used in any extrusion line - either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Three different sizes enable throughputs from 300 to 2,000 kg/h depending on the application.

PTC continuous melt filters are suitable for processing all standard polyolefins and polystyrenes with the exception of PVC、PVDC、EVA; they are designed to remove foreign particles such as paper, aluminum, wood, elastomers (rubber, silicone) or high-melting polymer composites from heavily contaminated materials.

How they work

All PTC high performance melt filters are based on the same principle:

Melt flows from the outside to the inside of a continuously rotating filter drum with a large number of conical holes. The contaminants contained in the melt are retained on the outside filter plates surface; they are immediately removed from the screen by a scraper and then fed to the discharge system

The filter drum and discharge system speeds can be adjusted independently of one another, so that in spite of the many possible applications the optimum setting can always be selected from both a processing and an economic perspective.

Through the application by our PTC automatic continuous filter, we save our customer’s occupation space, labor cost, material losses, energy and increate your profit margin!

Traditional filter exchanger in China requests heavy maintenance work by scrapping off the contamination, manually exchange of the screens, waste of the water/energy. Some of the customers have to set up two level filter machines in order to make the output meet the product requirements, which causes higher investment budget, higher maintenance cost, higher energy consumption and limited throughput capacity.

Upgrading your existing extrusion line or new production line with an integrated PTC Filter can increase your throughput by up to 200% larger filtration surface, which results in a lower melt pressure and therefore a lower mechanical strain on the material, better filtration results increased filter life time and reduced material losses. Filtration surface compared: PTC 500-D from JG: 3472 cm², Competitor I 350: 1570 cm², Competitor II 2/350: 1470 cm².

lower material losses

Filter systems from JG are designed in order to control and optimize the waste discharge of the filter. This can be achieved by the individual control of the filter screen speed, discharge screw speed, and the scraper system pressure.

longer life time

The variable scraper system pressure not only results in less material loss but also a better filtration result, due to variable pneumatic pressure system the lifetime of the filter screens is improved tremendously. The feedbacks of our customers reflect the fact that filter screens from JG have up 25 % greater lifetime compared to other manufacturers.

More reliable processing due to constant pressure at the filter outlet

Completely closed system with no entrapped air

Short contaminant residence times in the filter

Very simple replacement of the scraper from outside using a hydraulic cylinder

Easy maintenance and quick screen exchange kit

No need to replace the screen for several weeks, or possibly months, depending on the material and the application. Compacted quick exchange kit can dramatically reduce the filter exchange time to no more than 30min.

better filtration

The larger filtration surface and lower melt pressure is a key contributor to a higher quality of the final product due to filtration performance. This will result in higher customer satisfaction through improved quality as well as increased prices for better quality pellets.
