Pan Compost Pelletizer Working Process

Disc granulator is one of the important equipment for organic fertilizer production. Its main working part is a rotating swashplate. According to the principle of agglomeration granulation of powdery materials, the powdery materials with wet surface are continuously rolled or overturned in the disc granulator equipment, and mechanical extrusion is added to promote these powdery materials to gradually form particles. 

This machine is one of the important fertilizer making equipment in compound fertilizer production. The disc granulator can be reasonably selected through the parameters of the granulating disc, so as to improve the product output and greatly reduce the product cost.

1、 Principle of disc granulator

The disc is installed at a certain angle of inclination. The material in the disc rolls rapidly with the rotation of the disc body. When it rises to the highest point, it falls vertically under the stop of the scraper. During the rotation of the disc, the particles press and roll with the disc wall under the action of centrifugal force. Due to these comprehensive mechanical extrusion, rolling and collision, powdery materials are gathered together to form a "mother ball" through the surface tension of the liquid phase. 

With the increase of "mother ball", it gradually turns into complete particles, from small to small. The granulation process is completed until the particle size of the finished product overflows from the edge of the disc. Disc granulator has good classification function. It continuously makes powdery materials grow from the bottom of the pot to form particles and overflow into the outer pot. As the diameter of the outer disk increases, the linear velocity of the particles increases suddenly. The particles roll while rounding to form spherical particles. Larger particles are blocked by the discharge plate, will not overflow into the hopper, and will be sent to the next process by the belt conveyor. 

Many disc granulators are used in NPK fertilizer manufacturing process, but they can also be used in organic fertilizer manufacturing process.

2、 Technical parameters of disc granulator

In the production process, several parameters that will affect the granulation effect of the disc granulator are: disc diameter, disc height, inclination angle and disc speed.

Generally speaking, the diameter of the disc is mainly determined by the output. Each manufacturer shall select the combination matching with other organic fertilizer equipment such as mixer or screw conveyor according to its own situation, such as annual production capacity. 

The annual production capacity of the disc granulator with a diameter of 2m can reach more than 10000 tons, and the annual production capacity of the disc granulator with a diameter of 2.2m can reach more than 15000 tons. 

Therefore, the selection of disc diameter should be based on the design annual production capacity. Come and think about it. If the fertilizer granulator in the disc granulation production line is replaced by the strand granulator, this fertilizer production line is called drum granulation.

Drum Granulation Details

 How to promote the drum granulator working performance?

A certain amount of water or steam is added to the drum granulator fertilizer equipment to form a suitable solid-liquid ratio. Solid liquid materials are rolled and coated under the action of equipment to form particles of certain size.

Details of organic fertilizer production by drum granulator

1. The fertilizer granulator shall be equipped with two mixing powder boxes for granulation, so that the granulator does not need to stop when changing the formula.

2. A speed iron removal device must be placed before the organic fertilizer raw materials enter the roller granulator to protect the granulator from other impurities in the raw materials.

3. The organic compound fertilizer drum granulator should be placed on the cooler and the crusher should be placed under the cooler.

4. In order to make the organic fertilizer particles fall to the bottom of the box from a high place without damaging the bottom of the box, a vertical spiral slide should be installed in the box to slow down the impact force.

5. The finished product of granular organic fertilizer should be packed in the finished product warehouse. Pay attention to the fresh-keeping environment to avoid affecting the effect of organic fertilizer.

The above are some details that the granulator needs to pay attention to in the process of fertilization, which not only saves a small amount of power input, but also realizes the improvement of task efficiency, which is convenient and effective, and the effect is satisfactory. It has the characteristics of high strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life and convenient operation and maintenance.

Pan Pelletizer Working Principle

The main structure of disc granulator is disc. The disc designed by ShunXin fertilizer granulation plant is thicker, heavier and stronger, and the base design does not need to be fixed with anchor bolts, so the operation is stable. The granulation plate of pan granulator has three sockets, which is convenient for intermittent production and operation, greatly reduces the labor intensity and improves the labor efficiency. The reducer and motor are driven by flexible belt, which can start stably, reduce the impact force and improve the service life of the equipment.

The main motor drives the pulley and belt and drives the pinion through the reducer. The big gears fixed at the bottom of the disc mesh with each other and work in the opposite direction. The large gear is specially designed for mounting on the spindle of the housing adjusting disc to support the work of the whole granulator (in conjunction with the sprayer).

We have designed an automatic cleaning device on the top of the pan to prevent the material from sticking to the wall, thus greatly improving the service life of the pan granulator. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

The disc surface of the disc granulator should be flat and the disc roundness should be high. On the one hand, the CD theme affects the overall beauty of the device, on the other hand, it is also the most important. Only when the roundness and flatness meet the requirements, the equipment can run well, the bottom scraper and side scraper can play a role, fully contact the disc surface and bottom, scrape off the materials attached to the disk surface and bottom, and further form a spherical shape.

How does a disc granulator work for making your powdery fertilizers into granules?

Making your powder fertilizers into granules is essential, whether you want to sell or make use of them all by yourself crops. The whole process of turning powdery materials into granules demands a disc granulator. This machine can manufacture organic fertilizer in line with your unique requirements. Here's a concise description of this process, so that you can understand why and how to choose this sort of equipment for your personal fertilizer production plant.

A disc granulator consists from several devices, all of them with its own role with this process. The driving part accounts for making the shaft turn, thanks to belt pulleys plus a gear wheel. This piece of equipment drives the material into the pelleting disc, which is the most essential portion of the machine, the place where the powder is transformed into granules. The faster this disc rotates, the better the working efficiency of the machine. Nevertheless, there's a speed limitation, so you won't have the capacity to pick just any value you want. One of the more important things to remember is by governing the disc inclination, you'll be able to make high quality pellets. Last but not least, the device contains a scraper, that is installed on top of the pelleting disc. The scraper prevents the material from adhering to the disc wall. It can also help cleansing the disc from time to time, in order to prevent unwanted accumulations of material onto its surface.

This equipment uses wet granulation methods for making powdery fertilizers into pellets. A lot of people would rather include liquid to boost the adhesive force. As a result powders rotate within the disc until they become round granules. This process relies upon centrifugal force to unfold. In the last stage of the production process, these granules exit through the foot of the disc. Many small enterprises prefer this type of granulator, as it is for sale in sizes that fit labs and smaller firms that would like to manufacture their own fertilizer pellets to work with on their plants rather than buying them from third parties. Such situations, there's no need for mass production capacities, so a reduced machine would just do fine.

Of course, the fertilizer granules production line may also feature a packing machine. This piece of equipment is nothing but an automatic scale with a couple of buckets. It is going to pack your fertilizer granules to meet your requirements.

Remember that disc granulators can be found in a wide range of sizes. They might have different rotary speeds, different powers, and therefore different production capacities. Furthermore, it is possible to opt for the size and also the shape of the granules. Many of these machines permit you to manufacture several types of granules. Before purchasing your machines, make certain you completely grasp the way that they work and what are their specific advantages and drawbacks. Always avoid buying such equipment without asking several manufacturers for price estimates. You need to compare multiple offers to get the best decision, so take time to scout the current market in seek for reliable manufacturers of disc granulating machines as well as other such devices.
