CaCO3 High Filled MB Pelletizing Machine
Calcium carbonate was used to plastic industry a large number of is not accidental, compared to other non-metallic mineral powder material, calcium carbonate has obvious advantages. 1) Inexpensive Both TSP and light calcium are the cheapest in a variety of non-mineral powder materials, meaning that any non-mineral powder material will only attempt to replace calcium carbonate as a plastic filler rather than highlighting this The characteristics of the powder material itself, it is meaningless.
2)color is good ,is easy to put color,could make color light plastic product. Inadvantage is the plastic product color is not enough bright.in most cases is acceptable.
3)low hardness,much less than the manufacturing processing machinery equipment and molding the wear is light to the contact parts (screw,barrel etc) and molding.
4)Good thermal stability and chemical stability
5)Is easy to dry ,without crystallographic water, and the moisture of adsorption is easily removed by heating.
6)avirulent, without excitant, tasteless, especially our country is rich in calcite, marble, limestone resources, choose room is big, the vast majority of resources are of good quality, especially the heavy metal content is extremely low, to fulfill the requirements of national health level.
High filling master-batch usually adopt machine type:
1.Kneader + JDL single screw
Preprocess :pressurized mixer
Pelletizing equipment:single screw series
Cutting machine :air cooling hot cutting
Model M20+JDL 80 single screw
single screw motor power less than 37Kw,L/D<22:1
2.JS twin screw extruder
Suggest you adopt model: JS 52
Capacity:100-200kg/h
Motor :45Kw
Conventional configuration for the enquipment includes:twin screw extruder----mold die --hot cutting head cover -- air conveying system and vibrating sieve
