INTRODUCTION
The double roller press granulator is one of the fertilizer granulator equipment.It is a new designed fertilizer equipment by our company based on the fertilizer granulator machine.The machine is widely used for the fertilizer processing industry,feed production units and chemical industry to granulate,produce and process powdered objects.Roller extrusion granulator is the key equipment for compound fertilizer granulator,with advanced technology,reasonable design,compact structure,low engery consumption and the corresponding equipment.
WORKING PRINCIPLE
The dry powder material is added to the top of the roller press granulator, and the rolls are rotated by reverse and constant speed, biting the material and forcibly compressing.
After the compression, the pressure of the material is lowered, and under the action of gravity and surface tension, it naturally escapes, and the crusher is broken and the granulator is granulated.
Finally, the screener is sieved and the qualified product is packaged. For the material under the powder screener, the returning system returns the fertilizer powder to the raw material bin for re-rolling.
The size of the pressing force of the dry roller granulator can be adjusted according to the requirements of the strength of the granules. Different press rolls can be used for materials of different volume shapes.
Raw materials suitable for granulation
Ammonium bicarbonate, ammonium chloride, ammonium sulfate, ammonium sulfate, urea, diammonium phosphate, ammonium nitrate, magnesium sulfate, magnesium silicate, zinc sulfate, phosphorus pentoxide, etc.
1. Installation:
After the roller extrusion granulator arrives at the plant, take the granulator as the main machine, depending on the number of units, and install it in coordination with the granulation process flow chart to find out the elevation and horizontal placement. The machine frame has corner holes, which can be installed on the concrete (the fixed vibration momentum is not big and does not need to be very solid on the concrete foundation).
2. Debugging:
Roller press granulator has been started and debugged before leaving the factory, and can only be put into production after simple debugging after trial use.
