Granulator technology sources
Dropform granulator by the German Ryan • feshe roche invention
in the early 1980s , Applications from Switzerland Suntrad company,
From Sweden SANDIVK Group produced, Europe and the United States in the late 1980s to promote rapid industrialization, Particles have a revolution in the chemical industry. Makes more than 100 kinds of particles of the past can not be organic, inorganic chemical products to the particle.
World authoritative magazine “Chemical Engineering” has been reported that the machine “A Revolutionary Granulator” is of epoch-making significance.

Application:
Low melting point materials (usually refers to melting point in the materials between 50-300 ℃) in a molten state can be mobile, in a solid state at room temperature.
Typical applications materials: sulfur, paraffin wax, rubber, resin, pitch, maleic anhydride, TMA, satiric acid products, thermal Sol, phenylenediamine, urea, plastics additives and so on.
Performance advantages:
■ Uniform particle shape and size is conducive to transport, packaging , the use , the production and use of the process operating conditions and the improvement of the environment, improve product quality and competitiveness.
■ Heat a thin strip and atomizing spray forced cooling, hot-melt was expected to be rapid condensation, curing, productivity increased significantly.
■ Cooler system and dropform system are used Frequency Control device drivers, according to production capacity and material properties no-conditioning control.
■ A smart temperature controller distribution of the temperature control to ensure that the material temperature and material properties of stability, the quality of granulation reliable protection.
■ Discharge side of the strip for the bending, curing particles and the combination of surface strip easy peeling off, discharging dust when little, particle shape is protected, while also reducing the scraper when the impurity content into the product.
■ Sub used cooling, according to materials condensation, curing characteristics, the choice of the cooling temperature, special materials to achieve rapid cooling, curing extremely favorable
■ Sharpnozzle granulation systems in its structure using removable portfolio structure, according to material properties and production equipment specifications choice is conducive to large-sized transport and installation of devices.

Sulfur pelletizer
Product introduction:
The liquid sulfur is fed by means of a jacket pump from the storage tank to the drop former by jacket piping. These piping are heated by steam. The pastillating unit consists of a drop-former and a steel belt cooler. The drop former is designed according to the Sharp patented for REBO and consists of stator which is supplied with liquid product and a perforated rotating outer shell which turns concentrically around the stator depositing sulfur drops across the whole belt width. circumferential speed of the drop former is synchronized with the speed of the belt cooler. The drops are therefore deposited on the belt without deformation and, after solidification, result in regular pastilles with an optimum shape. The heat released during solidification and cooling is transferred by the stainless steel belt to the cooling water indirectly. This is sprayed against the belt underside, collected in tanks, and returned to the re-cooling plant, In no phase the cooling water gets in contact with the sulfur. At the cooler end the pastilles are taken off with a discharge knife and pass via chutes to a bagging system. The diameter of pastilles is about 3-6mm and its height is about 1.5-1.8mm. The width of the complete machine is 1200mm,1600mm,1800mm and 2100mm and its length is 13m. The output of single machine is 1500kg/hr, 3000kg/hr, 4000kg/hr and 6000kg/hr. It can be matched with semi-automatic or full-automatic packing machine to complete automatic packing and stacking.
Product advantages:
● The maximum capacity of single machine reaches up to 6000kg/hr;
● The sharp nozzle type patent technology, there are thousands rows of sharp nozzle hole on the surface of outershell;
● The innovation technology based on the introduction and ingestion of Germany granulator technology;
● Our company has passed united technology assessment by SINOPEC technology development center and the introduced major equipment domestication office, belonging to ministerial appraisal;
● The service life of steel belt is long, sulfur pastillse is plump, and with good flowability;
● The cooling water and product not contacting mutually, cooling water is not polluted by product;
● All large-scale oil refinery project with tens of millions of tons in the domestic adopt Rebo machine;
● Successfully renewed 30 imported Germany machines, and 3 American machines, with a total of 33;
● Easy operation, less wearing parts, low operation cost, stable quality and low fault rate;
● Continuous steel belt and equipment overall package ensure that steel belt does not deviate and damage V rope;
