The double roller press granulator is a new designed fertilizer equipment by our company based on the double roller fertilizer granulator machine. The fertilizer granulation machine is widely used for the fertilizer processing industry,feed production units and chemical industry to granulate,produce and process powdered objects. It can produce various concentrations and types of compound fertilizers (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.). In particular, rare earth, potassium fertilizer, ammonium bicarbonate series compound fertilizer granulation.


The belt is driven by the electric motor making the transmission belt to transmit a pair of two high pressure rollers and the sliding housing to do the relative  work through the reducer.The two rollers of the DZJ--I series double roller machine with the relative work of the open gear begain to working,and the two rollers of the DZJ-II were directly outputed  by the two output axes on a special reducer,so that it can get the purpose of extrusion molding.
When the raw material is produced, the raw material enters into the hopper, and is extruded and molded through the high-pressure roller body, and then flows to the broken molding workshop of the lower part of the roller body after demolishing. The driving force of the crushing molding is that the chain wheel of the active roller shaft is driven by the chain to a pair of broken rollers to carry out relative motion, and the broken roller is sieved in the workroom, and the finished particles are out of the machine through the screen to the discharge slot.
1. It doesn't to be dried.The machine is made of non drying process, granulated at room temperature and molded at one time. It has the characteristics of less investment, quick results and good economic returns.
2. Less investment,quick results,good economic benefits,compact equipment,scientific and reasonable,advanced technology,engery saving and consumption reduction.

3. Stableoperation,reliable operation and convenient maintenance.The raw material has wide adaptability and is suitable for granulation of various raw materials such as compound fertilizer,medicine,chemical industry and feed,and the product has high granulation rate.

The whole machine is divided into four parts:
1. Frame part: all working bodies of the machine are installed and fixed on the frame. The frame of the machine is made of medium carbon steel plate and channel steel. It has passed strict quality control and specific process requirements to achieve the purpose of the machine. There are lifting holes in the middle of the four corners of the frame to facilitate Used in loading and unloading transportation.
2. Transmission connection part: the motor drives the belt pulley, V-belt, and reducer to make the machine head work. In addition, sprocket and chain form a transmission chain which is transmitted to the crushing and separating work part. Among them, the transmission reducer and the working part of the machine head are engaged and driven by a nylon pin coupling.
3. The working part of the machine head: from the transmission wheel to the transmission roller shaft through the pin coupling, the synchronous operation of the rollers is ensured by a pair of open gears. There are specific bearings on both sides of the active and passive shafts, which are composed of bearing frames and are installed On the rack.
4. Crushing and separation work part: the material flows into the crushing chamber to the lower side after being squeezed by the rollers, and the pellets and the return material can be separated by the rotation of the biaxial mace.
The main parts, such as rollers, are made of a new type of metal with corrosion resistance, wear resistance and impact resistance. The DZJ-II machine not only has the above characteristics, but also the frame part has also been upgraded. The bearing frame is selected as the whole component with high quality anti-corrosion casting. With more stable performance, it can greatly improve the service life of the rolling bearing and shaft.
For the transmission part, we apply the dual input transfer mode, which not only improves the input power ratio, but also ensures the lubrication and sealing performance of the transmission gear. The machine has the advantages of compact structure, good stability, good sealing, low noise, convenient operation and maintenance. After the new machine is listed on the market, it won the praise of the vast number of users!
