Ammonium sulfate fertilizer granulator, suitable for powder material with moisture content less than or equal to 5%
Granular strength can be adjusted by adjusting the pressure of roller, control strength of final products. 1. Cycle operations to achieve continuous production. High yield of finished products. 2. Materials are force to compress molding by mechanical pressure, without any additives, the product's purity is guaranteed. 3. Dry powders are granulated directly without follow-up drying process, the existing production process is easy to convergence & transformation. 4. Granular strength is high, compared with other granulating methods, the improvement sof bulk density are significant,especially for the occasion where increase the proportion of product accumulation. 5. A wide range of raw materials can be used, granular strength can be freely adjusted according to different materials. 6. Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate. 7. Control environmental pollution, reduce waste and powder packaging costs, and improve product transport capacity. 8. Feeding device adopts frequency adjustment control, high automation ,one can control multi-machine, low labor intensity and long term continuous operation,etc. 9. Major transmission components use high quality alloy material. Stainless steel, titanium, chromium and other surface alloys which greatly improved wear resistance, corrosion resistance, high temperature and pressure capabilities, so that this machine has one long service life. 2.Multiple sets of processes     This process is the process of multiple sets of equipment, can be designed according to the site and customer demand, single bucket elevator can be used for loading and granulating, or lifting to the feed hopper, use hopper to feed. After the process of crushing and screening, the materials are crushed and screened.     "Mixing - granulation - pre crushing - concentrated crushing - Screening - polishing - second screen - packaging", After the screening ,fine powder material to return to the raw material mixing again into the granulation system to form a granulation cycle, improve the granulation efficiency of the granulation process.     According to the demand, the granulation of the preceding paragraph can be added batching or drying system,in this process, due to the larger strip produced by the tablet, the lower end of the granulation machine is equipped with a pre crushing machine, pre crushing and then concentrated crushing. The qualified material produced by the screening enters into the next polishing, second screening and the packing process, and the screening out of the unqualified large particles are returned to the impact crusher for re broken, the unqualified fine powder is returned to the raw material place to carry on the re granulation. Services     Our services cover material tests, process layout, engineering, and supply of complete granulating plants or key equipments, guidance of installation and commissioning, training. Also, the company manufactures and supplies equipment for drying equipments and dust collector machines. Paper industry has special environment, such as high temperature, high humidity and frequent loads, etc., thus the requirements for Overhead Crane is quite high.Accumulating years of industry experience and keeping innovation,Eurocrane has formed standardized industrial crane design criteria.
