Double plate type continuous screen changer of extruder machine parts for plastic granules making machine
Screen exchanger Introduction:
- continuous operation
- Leak-free mold of operation
- Customized design adapters
- optional choice of installation ways
- venting groove discharge the gas mixed in the polymer melt
- Simply controll by a easy operated control handle
- Reasonable price and proved technology
In order to considerably increase the lifetime of the filter media GS-MACH offers automatic backflush screen changers.
Working principle (backflush process)of this double piston backflush screen changer with 4 screen cavities fortwin screw extruder
These systems work as follows: When a pre-defined pollution degree is reached, the backflushing automatically starts.
Then the contaminations from the screen pack are led out of the machine via a spillway. The contaminated backflush mass leaves the machine by means of heated backflush outlet pipes which are installed at the screen changer housing. There the small quantity may be removed or collected.
With the-channel screen changers additional slide valves are used at the backflush channels. There is no interference of the process during backflushing.
Features included
1, Continuously working melt filter
2, Four working stations
3, venting groove can discharge the gas mixed in the raw material
4, no interference during the process of backflushing
5, the screen cleaning reached 85%
6, long life span of the filtration screen pack/mesh , it owning to up to 100 times backflushing at most.
