Process Operation
Drying system  consists of a hot gas generator system. Lump breaker cum Screw Conveyor for feeding. The  Main Dryer
 comprises of a shell at the bottom of which is mounted a shaft with a high speed disperser which also has mounted on it a high speed agitator cum scraper. At the top of this section is a nozzle into which the screw conveyor feeds material. A tangential nozzle is provided at the bottom to allow inlet of hot air. The drive is through a single motor through V -belts and Pulleys. This is basically cylindrical in nature and has within it the classifier which enables the final dried particles size to be maintained within the desired range. The outlet of the solid and air is provided in this section after drying and classification has taken place. The dry powder is collected by 
bag filters. These Filters are fully automatic and self-cleaning with no internal moving parts. Control_Panel 
A Control Panel mounted with necessary starters, switches, push buttons etc., and pre-wired for all motors comprising the system will be in our scope of supply. However, all cabling and wiring to the panel and from panel to respective motors will be in client’s scope. Instrumentation necessary for the safe and simple operation of the plant is supplied. This will include a temperature controller and temperature sensors etc..
