It is interior out after be transported to through opotism elevator in dryer, the temperature of dryer is 500 DEG C, and granular potassium sulfate is from dryer
Arrival end is oven-dried during running to the port of export, subsequently into being cooled down in cooler, connects the blower fan work of cooler, to
Transporting cold wind in cooler, granular potassium sulfate are cooled to 70 DEG C in cooler, are then sent to multistage through bucket elevator
Sieved in roller screen-dividing machine according to the specification of particle, the granular potassium sulfate after screening respectively enters finished product bunker and waste product storage
Storehouse, the material for entering waste product bunker is put into agitator again, produced again.
Process potassium sulfate round shaped grain used in equipment include cast feeder, agitator, tripper, comminutor, horizontal conveyer,
Pre- heat setting machine, opotism elevator, dryer, cooler, bucket elevator, multiple rollers screen-dividing machine, product bunker, waste product storage
Storehouse；The outlet of described cast feeder is connected with the entrance of agitator by pipeline, the outlet of agitator and tripper entrance it
Between connected by pipeline, each outlet of tripper is connected by pipeline with the charging aperture of several comminutors, several comminutors
Horizontal conveyer is provided between pre- heat setting machine, is provided with roller in pre- heat setting machine, roller is mounted in pre- heat setting machine by axle
On, there is ash bucket below roller, connected between pre- heat setting machine and an air-heater by airduct, pre- heat setting machine and dryer
Between be provided with opotism elevator, connected between dryer and another air-heater by airduct, dryer outlet and cooler
Connected between entrance by pipeline, bucket elevator, cooler are provided between cooler outlet and multiple rollers screen-dividing machine entrance
Connected between cold wind blower fan by airduct, the material outlet of multilevel screening machine is store by pipeline and product bunker and waste product respectively
Storehouse entrance is connected.
It is an advantage of the invention that：Because in process of production, the granular potassium sulfate out of each comminutor out is through horizontal defeated
Send machine to be sent in pre- heat setting machine and carry out pre- thermal finalization, and enter in dryer and dried, then cool down, so obtained sulphur
Sour potassium round shaped grain regular shape, hardness is big, and quality is good, and production efficiency is high.In addition can continuous production, power consumption is few.
