Co-rotating Parallel Twin Screw Color Masterbatch Granulator

Haisi extrusion provides advanced pelletizing line for all kinds of color masterbatch.

We design the color masterbatch extruder according to the output, formula and final application as your request.

1.Water strand pelletizing line for color masterbatch extruder

It is the most commonly used and economic method for color masterbatch making.

Application:

Incorporation of Fillers: Caco3, Talc, TiO2, carbon black,filled PE, PP, or EVA, etc.

High Concentration Color Masterbatches: PE, ABS, PS, EVA, PP,etc. with high concentration of pigments and other processing aids.

Masterbatches with Flame-retardants: PE, ABS, PS, EVA, PET, PP, etc. with flame retardants and other additives.

2. Water Ring pelletizing line for color masterbatch extruder

Water ring granulation can be applied to formulations with large differences in melt characteristics. On the other hand, the water ring cutting have a shorter residence time in the water, and the moisture content after the dehyddrator and the vibrating screen is less than 0.1%, and no additional drying is required.

Application:

PE, EVA etc. Filled with CACO3,talc,TIO2,carbon black etc.

Color concentrations of PE,ABS, PS,EVA,etc;

Flame retardant master batches of ABS,PS,EVA,etc;

Master batches with PE,PP,PS,etc carriers for degradation applications.

3.Underwater pelletizing line for color masterbatch extruder:

For more output: the strands go into the pelletizer automatically by the water flow, even the strands break during changing the filter. So there will be almost no waste during the manufacturing process.

Underwater pelletizing system also used to handle micro pellets making with a size of  ≤ 1mm.

Characteristics of color masterbatch extruder：

*TSE series color masterbatch extruder use innovated design of heater tightened style, it insures high efficiency of heat transfer and high longevity of heater.

*TSE series color masterbatch extruder has various modes of pelletizing, such as water-cooling strand machine, air-cooling pelletizing machine, water-ring pelletizing machine, under water pelletizing machine etc.

*The screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2 by special heat-treatment, which is possessed with high corrosion-resistant and high functions.

*The screw configuration, barrel setup, L/D or mode of feeding and venting, screen changing, way of granulating, and the control mode can be optimally adjusted according to different materials properties and requirements in consideration of the versatility in each general applications.

Various additives or fillers will also be added to the color masterbatch according to the customer's requirements for product functionality and cost, in order to improve the performance of the color masterbatch.

For example:

Adding coupling agents or surfactants to improve the binding ability between pigments and resins.

Adding lubricants - increases the flowability of the colored resin.

Adding brightener - demolding the molded product and improving the surface brightness of the product.

Adding antioxidants - improving the antioxidant performance of products.

Adding ultraviolet light agent to enhance the aging resistance of products.

Color masterbatches are widely used in the plastic processing industry and synthetic fiber processing industry.

At present, the general masterbatch preparation method can be divided into dry and wet methods, and the dry process route is as follows:
