DG Series Double Roller Granulator
Our company offers a wide range of machine sizes for high pressure granulating, which covers nearly all requirements of the clients. If your production is low,you can choose small type machine, if you have high production, you can choose one or more sets of machines according to your requirements.And certainly the process of granulating is dry.
Overview
DG series double roller granulator adopts no-drying process granulating at normal temperature and once forming. It can produce 2-6mm irregular granules,Ø3.8-Ø10mm oblateness granules and all kinds of slice products. It is a multi-purpose machine and widely used to granulate the powder materials of fertilizers, medicine, chemicals, etc, especially suitable for the production of palletized fertilizers such as ammonium bicarbonate, carbamide, ammonium chloride, ammonium sulfate, potassium chloride, potassium sulfate, salt, binary, ternary compound fertilizers(Nutrient content 25%-53%), blended fertilizers and so on. Our company can tailor the chemical fertilizer production lines from 30,000 to 500,000 T/Y according to the requirements of the customers. The complete sets of the equipment are in compact layout process, scientific and rational, leading technology, energy saving, EPT protection without waste emissions, operation stability, and easy maintenance.
Working principle
As is shown in the figure, the granulation machine is mainly divided into two parts, granulation and broken, after full mixing the material from the hopper mouth continuous feeding into a pair of roller of two models, the gap between the rollers can be adjusted properly, At the same time, in order to ensure that the cavity on the two roll can be completely on the upper, which has a roller can be adjusted as appropriate. At the same time, in order to ensure that the cavity on the two roll can be completely on the upper, which has a roller can be adjusted as appropriate. Granulation molding part is mainly composed of a motor, a belt drive device, hardened special reducer, coupling, gear, bearing, bearing, roller, feeding hopper etc..
Crusher is mainly spreading sheet material from molding material. It is mainly composed of motor, transmission device, gear, bearing block, bearing, broken tooth and other. The roll material of the equipment is alloy steel, broken tooth is made of stainless steel. Main chassis and bearing seat to consider corrosion resistance and stability, other materials HT200 casting, hopper and material for stainless steel, the other material is Q235.

Features
DG series double roller granulators are the key equipment for the production of pelletized fertilizers. It has the features of advanced technology, rational design, compact structure, novelty and practicality, low energy consumption, fit to relevant equipment, single or multi-machine combination. It can form continuous, mechanical production lines with 15,000T to 100,000T annual output; it can optimize the formula, adopts no-drying process, production in normal temperature and once forming products. The quality of its products is in conformity with the technical specifications of the compound and blending fertilizers. Especially, the double roll palletization of ammonium chloride, ammonium sulfate, ammonium bicarbonate, potassium chloride and other fertilizers fills a blank in China. It can produce all kinds of high, medium and low concentration dedicated compound and blended fertilizers. It is one new generation upgrade and update product of saving energy and lowing consumption in the compound and blended fertilizer industry.
