Granulation is made of the following major components:1,Drop-former.2,Cooler.3,Control system . Principle : Liquid product reacting in the vessel or storing in the agitator is fed by means of pump through filter into Granulator and solidified on the steel belt in the cooler. After solidification, The pastille product is taken off with discharge knife and pass via chutes for bagging or by means of a conveyor to the silo for automatic weighing and packing.
From drop-former system dropping to product discharge, Cooling materials probably divided into three parts, The first stage is pre-cooling process. In this process, materials from High-temperature liquid cooling to the melting point temperature;
The second stage is Curing process ,in this process, materials from liquid droplets into a solid, in the process material release more heat, the material itself temperature remain unchanged; The third stage is materials cooling process, materials in the process from the melting point temperature to the temperature for product packaging;
Based on the above three phases of materials the sum of the time required for cooling, and materials on the strip at the time T, users of the requirements of Q production capacity can be identified equipment performance parameters and specifications of the model.
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.
■ 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 drop-former 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
■ Pastillation 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.
In addition, we also have product testing center, users can take on the material in the granulator for molding products granulation testing also gives users strip, strip welding, V rope banding, spare parts and maintenance service etc
