Learn how to improve the life of your screen changer

The main function of the hydraulic non-stop screen changer in the production line is to filter impurities in the melt and provide a clean melt for the subsequent sequence; the application of the screen changer can also improve the plasticization and homogenization of the melt. Improved product quality, more uniform texture, better surface quality and finish. Compared with the manual screen changer, the polymer extruder screen changer can replace the filter screen without downtime, saving energy and reducing energy consumption. At the same time, it can increase output and reduce labor intensity.

The operating trick of the screen changer is to optimize the number of heating stages, which is necessary to balance the temperature on the screen changer. more specifically:

1. At both ends of the skateboard, it is better to use three sections with a pair of integrated sections, and two independent sections with two sections. Many processors connect these converters to separate control sections, causing the skateboard to heat up too much or too little. This will destabilize the temperature distribution of the melt and cause the material to scorch in the off-line breaker.

2. For continuous bolt screen changers, it is usually better to use a single control end, but as these machines increase in size, additional body parts are required to help balance the heating. The bolted continuous mesh heat exchanger heats the bolts through the heat conduction of the body. If the heat is unbalanced, the body can shrink to the point where the bolt creates a clamping force high enough to prevent the bolt from moving.

3. For the die sleeve of the machine, it is usually better to use an independent heating controller. However, this will vary with size.

Hydraulic screen changer equipment in extruder needs skilled operators to check regularly. Due to the large vibration of our equipment, our equipment is easy to shake and fall off parts, so we must pay attention to the wear of our parts, so as to prolong the life of our hydraulic screen changer. service life. The recycling of plastic materials, especially those used in food and beverage packaging, such as pet, is not only beneficial to the ecological environment, but also has huge economic effects. As a result, many new technologies and processes for cleaning and recycling warm plastics have been developed, such as mechanical filtration processes (filtering of solid particles out of the melt). To meet the requirements of this process, the production cost of recycling is minimized.

The continuous screen changer developed by Batte Melt Pumps is suitable for highly contaminated melts. Its backwash system can clean the filter screen without stopping. Specifically, in the production of highly polluting melts, in order to avoid frequent screen changes, the backwash screen changer provides a larger filtering area and can automatically clean the screen by backmelting. The company mainly produces and sells melt pumps, rubber gear pump, reactor kettle melt pump, chemical dosing melt pump and loss in weight feeders, volumetric screw doser feeder.
