Bentonite Dryer Machine

Bentonite is mainly used for destaining petroleum catalysis and mineral oil, vegetable oil etc, whose moisture content is in 30 ~ 45%. When put into the dryer, bentonite with strong viscosity will be difficult to be dry and easy to produce about 100 mm mass of materials if it doesn’t adopt to the dryer structure. If the temperature in the bentonite dryer is too high, it will cause the montmorillonite in the production lose too much crystal water, which will severely decrease the activity degree. And if the temperature is too low, the free water is difficult to be dried, and the production will not be easy to save, which will also decrease the activity degree. Generally speaking, the moisture content in the dried bentonite is under 10%. 
 
According to the special characteristic of bentonite and analyzing the effect of dryer structure to the productivity and quality of bentonite, our company designs the dryer with comprehensive technical transformation, which improves the material fill rates and prolong the time of material leaving in the cylinder. This dryer machine is designed with combined feed devices to extend the area of bentonite particles contacting with hot-blast air, which makes the bentonite get sufficient heat exchange and improves the heat utilization efficiency and then increases the productivity.
 
Introduction of bentonite dryer machine:
 
Desiccant is composed of highly purified montmorillonite, a kind of natural alumino silicate mineral with two-dimensional open structure.
 
It can strongly adsorb water molecules to a high level as that of silica gel in the air through the Mg or Ca cation hydration and capillarity in the laminas of the montmorillonite
 
 
Package: 
 
the bentonite after drying to package , one bag weight from 0.5g to 3,000g or as per customer's request by paper or nonwoven, airtight in PE barriers and carton with HIC.
