Application of Twin screw metering feeder:

In the extrusion processing, it is common to add many material (such as color, flame retardant, glass fiber and so on) into extruder. In the process of continuous extrusion production, various material should be added to extruder continuously synchronized. And the adding speed of these materials should depend on corresponding formula, so metering feeder is necessary to control the adding speed. And one metering feeder control one material.
Loss-in-weigh feeders is suitable for plastic granules, powder, calcium carbonate, talcum powder, resin membrane powder, flour, starch and so on. Different material use different feeders.

Characteristics of Twin screw feeder:

◆ Generous and beautiful appearance: comparing with traditional feeders, Batte dose more improvements on feeders’ appearance.
◆ Small in size: easy to move, more suitable for changing and improving production process.
◆ Low noise: comparing with other feeders, noise of Batte feeders is up to perfect.
◆ Easy to clean and maintain: it’s easy to maintain in operation, meanwhile, very short maintenance time. Especially the control system, adopting the leading software and hardware, are nearly free-maintenance and long-service life.
◆ High feeding accuracy: Batte adds self-detection function when designing its feeders for more accuracy, it allows to detect attritions of parts and frequency variation timely, then revise them. So the feeder will not affect the feeding precision because a little change of the machine.
