The drum granulator is suitable for granulation of light and fine powder materials. The finer the basic particles of fine powder materials are, the higher the sphericity of particles is, and the better the quality of pellets is. It is generally required that the particle size of the material before granulation should be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, sheep manure, carbon black, clay, kaolin, etc.
The fertilizer granulator machine uses high-speed rotation, mechanical stirring and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization and densification of fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is 0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is 90. The size of the particle diameter can be adjusted by the material moisture size, mixing amount and spindle speed. Generally, the lower the mixing amount, the higher the rotational speed, the smaller the particles, and vice versa.
Drum granulator belongs to wet granulation of pellets. Through a certain amount of water or steam, the basic fertilizer can be fully chemically reacted after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the material particles are squeezed and agglomerated into balls. The granulator machine for fertilizer adopts special rubber plate lining or acid resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, and cancels the traditional scraper device.

In fertilizer industry, roller granulator process is short, energy consumption is low, and auxiliary equipment and personnel allocation are few.
Working principle of roller granulator: all kinds of dry powder materials are added from the top of the equipment, and then enter into the opposite roller through degassing and screw preloading. Under the action of the maximum extrusion pressure of the opposite roller, the material will produce plastic deformation and be compressed into flakes. The flake material is crushed, granulated and sieved to obtain the granular product. The extrusion pressure can be adjusted by the pressure of hydraulic cylinder according to the needs of granulation operation.

It is especially suitable for granulation of materials which cannot be solved by wet method.
technological process:
The raw materials are pre compressed by the screw feeder at the feeding port. The pre compressed materials are pressed into the middle of two pairs of relatively rotating rollers for compaction. The pressure strength is transmitted to the materials by the pressure rollers through the thrust of the oil cylinder. The compacted sheet materials automatically take off the groove and enter the crusher to crush them into particles with uneven size, and then enter the granulator for trimming. The finished particles are extruded out through the sieve plate with mesh holes and enter the screening machine. The finished particles are sent into the finished product bin by the bucket elevator after screening. The sieved powder is returned to the raw material bin by the screw conveyor, and then compacted again to complete a closed cycle.

Dry granulation equipment
When purchasing roller granulator, in addition to the quality of the equipment and the price of the equipment, the production effect of the granulator must also be considered. As the manufacturer of dry granulator, the company has always advocated users to test the machine with materials. On the one hand, users can more intuitively detect the real effect of the manufacturer's equipment, on the other hand, it also provides guarantee for the production of users. The granulator machine for fertilizer adopts dry extrusion technology to compress powdery materials with water content less than 10% into flakes, and then through crushing, pelleting and screening processes, the flake materials become granular materials meeting the requirements of use. The roller granulator mainly relies on the external pressure mode, so that the materials are forced to pass through the gap between the two opposite rotating rollers and compress into pieces. In the process of rolling, the actual density of the material can be increased by 1.5-3 times, so as to meet certain strength requirements.
Working principle of roller granulator: all kinds of dry powder materials are added from the top of the equipment, and then enter into the opposite roller through degassing and screw preloading. Under the action of the maximum extrusion pressure of the opposite roller, the material will produce plastic deformation and be compressed into flakes. The flake material is crushed, granulated and sieved to obtain granular products. The extrusion pressure can be adjusted by the pressure of hydraulic cylinder according to the needs of granulation operation. Two relative moving rollers are used for extrusion forming. There is a certain gap between the two rollers (adjustable), and the two wheels rotate at the same speed. One group of roller seats is fixed, the other group is sliding to help the hydraulic cylinder press against each other. Many arc grooves of the same shape and size are arranged regularly on the surface of the roller, and the two rolls are in a horizontal parallel state. The powder and granular materials are pressed continuously and evenly from the top of the two rollers to the rolls by the self weight and forced feeder, and then they are formed under the high pressure of the two rollers. Next, it enters the chopping device for granulation, and then the screening machine is used to screen out the finished product particles. The screened out defective products can be put into the fertilizer granulator machine again for secondary granulation. The particle shape depends on the shape of the arc groove on the surface of the roller (e.g. oval, sheet or strip).
The correct installation or replacement of the pressure roller of the double roller granulator is generally to use a new mold with a new roller, and an old mold with an old roller, so that the surface shape of the pressure roller is close to the profiling state, and the gap of each part of the pressure roller is approximately the same. In this way, the force and discharge of the entire roller are very uniform, which can improve production efficiency.
Before assembly of the roller granulator, the cleaning work should be done to ensure that the matching surface is clean. Special attention should be paid to the cleaning of the ring die screw hole. If the screw hole is not cleaned, it is easy to cause the bolt hole fracture when tightening the ring mold bolt. Torque wrench shall be used to tighten the ring die bolt to ensure the specified tightening torque.
When assembling the press roll fertilizer granulation machine, pay attention to the inspection of the bearing. Once the damage is found, it should be replaced in time. After the press roll is assembled, there should be a certain clearance to make the roller rotate freely. Every shift must oil the roller on time. Once the roller is short of oil, the bearing and roller shaft will be burned, and the whole roller will be scrapped.
The dry process double roller granulator has novel and reasonable structure, stable and reliable performance, low noise and convenient cleaning and maintenance.

After repeated work for a period of time, the roll skin of the opposite roll granulator is seriously worn and can no longer be used. It needs to be replaced. The opposite roll extrudes the roll skin of the granulator and stainless steel mold accessories. Our company has a large number of roughcast roll skin of the granulator and granulator accessories, which can be made according to the granulation diameter required by customers. The roll skin of the fertilizer granulation machine is made of alloy steel. After a series of processes such as high temperature forging and machining, the finished product is made and then quenched at high temperature. Through these processes, the roll skin of the granulator is wear-resistant, corrosion-resistant and has long service life.
The double roller granulator is a granulation process in which the solid materials are gathered by using the strong pressure of the equipment. This kind of granulation discharge does not need to pass through the boring process. The material is kneaded by two counter rotating rollers in the twin roll extruder granulator. When the solid material is subjected to the external force of the extruder granulator, the air between the powder particles is first swept to rearrange, so as to eliminate the empty space between the materials. When the material is kneaded by the extrusion granulator, the particles will deform or move, and a strong van der Waals gravitational recombination occurs. At the end of the kneading granulation process, the energy composed by pressure to the system will form a hot spot at the contact point between ions, but the material will melt, and the fixed and undeformed particles will be formed when the temperature decreases and the material cools after discharging.
In the granulation process of extrusion fertilizer granulation machine, because the product is always dry without drying, the process reduces energy consumption, simplifies the process, avoids nitrogen loss due to high temperature, and does not pollute the environment. The water content of extrusion granulator is controlled, which is 6% - 8%.
