Chemical pastillator / granulator is a kind of equipment to make chemical granules. The equipment mainly consist of feeding (molten material) system, dropping system, cooling system, unloading system and control system. The major working step is following:
1. The molten raw materials (such as rosin resin, sulphur, paraffin wax) is inlet into the dropping header via filter, pump and pipes.
2. The molten raw materials is ejected from the thousands of holes of rotating dropping header and dropped onto the upper surface of stainless steel belt. Then the molten materials become to thousands of soft semi-liquid granules.
3. There are large amount of cooling water spray nozzles installed in the water tank under the running stainless steel belt. Water nozzles spray cooling water to the lower surface of the stainless steel belt continually.
4. Soft semi-liquid granules follows the steel belt. They are cooled and solidified in the whole ways. When the granules are transported to the end of the equipment, they will become solid granules and will be scraped off the steel belt.
KEY FEATURES AND OPTIONS
1. High quality stainless steel belt is used to cool and solidify the material rapidly. Due to the reversing bending of the steel belt at the discharge end, the joint surface between the steel strip and the solidified material is separated, so that the granules are complete without damage. And there is no dust and sewage during discharge. The production environment is good.
2. Inverter control of distributor and steel belt is adopted. The speed can be adjusted and controlled according to the production capacity and physical parameters. The equipment has high degree of automation and simple operation.
3. It has a wide range of applications. It can work with large amount of kinds of chemical raw materials.
4. The granules is uniform, regular and beautiful, and the granulation rate is at least 98%. The granules's shape is semicircular and the size can be selected between 3-12mm.
5. Through the installation of automatic deviation-correcting function of steel belt, the steel belt can run smoothly without deviation and climbing in the process of long-time continuous operation. It effectively extends the service life of steel belt.
