Features for Double screw masterbatch dosers 
The metering masterbatch machine is suitable for the automatic proportioning of new materials, secondary materials, masterbatch, or additives, and the error value is not higher than ±1%.
The standard model of metering masterbatch machines cannot be used for the treatment of all kinds of plastic powder masterbatch and the treatment of all kinds of food, chemicals, flammable, explosive, and volatile materials. If the customer's product is an optical industry product, such as PC, PMMA, etc., the standard masterbatch machine model cannot be selected. The part in contact with the raw material needs special treatment, such as the use of food-grade materials and polishing treatment.

working principle for Double screw masterbatch dosers 
The signal from the control box is transmitted to the motor, the motor starts to rotate, and the screw is driven to rotate through the coupling. The color masterbatch in the hopper falls into the drop rod, is squeezed by the screw, and is conveyed to the base by the screw, so as to achieve the purpose of accurately metering and conveying the color masterbatch.

Application for Double screw masterbatch dosers 
In general, the metering masterbatch machine is directly installed at the inlet of the molding machine. In order to prevent the control box from shaking with the action of the molding machine screw and causing the loosening of related accessories, it is recommended to fix the control box on a bracket. The motor reduction ratio of this product is divided into 30:1 and 50:1, etc. The screw diameter is divided into five types: 12, 16, 20, 25, and 30mm. Six models can be evolved to provide different outputs from 0.1 to 50 kg per hour. For customers to choose. There is also a two-color masterbatch machine, which can be combined with any two masterbatch machines according to customer needs. Metering masterbatch mixer/ Colors Volumetric Dosers.
