Strong granulation system process

The process of efficient and powerful granulating system is mainly composed of crushing system, drying system, batching system, grinding system, granulation system, raw material drying and calcination system, finished product screening and packaging system.
Among them, the crushing system for bauxite through the bar feeder into (or by forklift and other direct into the) jaw crusher for a broken, and then by the large angle belt conveyor into the second crusher, broken of the finished ore by the bucket elevator into the spiral with a slag to the storage silo for storage, cutting, the usage of vibration feeder to the finished ore discharge to the large dip belt conveyor, through the belt conveyor to the ore into buffer the warehouse, into the drying system.
Drying system for the buffer silo directly to the finished ore through the chute into the dryer, the blower will be hot air furnace generated high temperature flue gas into the dryer, in the dryer internal high temperature flue gas and finished ore for heat exchange at the same time. The ore is dried and finally discharged from the head of the dryer, into the batching system, and the waste flue gas is purged by the blower by the bag filter and discharged into the atmosphere.
The batching system uses the bucket elevator to store the dried clinker into the storage bin. When the ingredients are needed, the bauxite clinker, the manganese powder and other additives by the measurement, the ingredients sent by the belt conveyor into the grinding system; grinding system is the ingredients of the raw materials into the ball mill for grinding, the separator and bag filter selection filter. After the 400 mesh the following qualified powder into the granulation system, large pieces of material into the ball mill again, go on the second grinding.
The granulation system is finished powder in the buffer silo through the self-opening valve into the reversible spiral, and then were sent to the main measurement and auxiliary metering tank, the water system by the measurement tank and buffer water tank, feeding system and water system are by the pneumatic butterfly valve and weighing system control, granulation, open the pneumatic butterfly valve, respectively, to the powerful granulator inside the cylinder to add materials and water, powder material in the strong granulator rotor and drum retrograde high speed "rub" Gradually grow nucleation, and finally by filling powder, polishing, shaping, open the discharge gate, raw ball through the large angle belt conveyor into the raw material drying and calcination system.
Raw material drying and calcination system for the raw material ball drying machine, into the drum sieve for semi-finished product screening, screening qualified semi-finished product ball through the rotary kiln at 1000 ~ 1400 ℃ for 0.5 to 2 hours after calcination, into the monocular coolant for cooling, and ultimately into the finished product screening and packaging system, unqualified materials by crushing, grinding, re-enter the granulation system.
Finished product sieving and packaging system for the cooling of the finished ball material by the bucket elevator into the cylinder sieve or vibrating screen, the screening of finished product ball after packaging by the storage, substandard ball material as waste disposal.
