Making Ball Shape Granules

Pelletizing Disc

Disc granulator is a new type of inclined disc granulation equipment that is an important part in fertilizer production. It is widely used in chemical, petrochemical, pharmaceutique, nourriture, matériaux de construction, mining and metallurgy fields. En plus, the machine has advantages such as high granulation rate, bon fonctionnement, faible coût, sturdy and durable construction, longue durée de vie, etc.. De toute façon, it is an excellent granulator for fertilizer manufacture.

Notre usine produces various models of disc fertilizer granulators, which are designed to vary with the inner diameter, edge height and rotary speed. Ainsi, you can select different models of disc granulators based on your output capacity.

Can Disc Granulators Handle Various Materials?

Disc granulator, also known as a pan granulator, is a type of equipment used for granulating various materials into granules or pellets. The specific materials that can be used in a disc granulator depend on the nature of the material and the intended application. Here are some common types of materials that can be of applications by using the disc granulator.

1. Pelletizing Disc for Fertilizer Production

Granulateur à disque is commonly used in the production of different concentrations and types of granulated fertilizer including engrais organique, bio-organic fertilizer et engrais composé. It is typically used in conjunction with a broyeur, séchoir, machine de criblage, machine d'emballage, etc..

Organic Fertilizer

Premièrement, raw materials for making organic fertilizer pellets are free of chemicals. En général, pan granulator can make round balls from many organic waste. Par exemple,

Animal Manure: Poultry litter, fumier de poulet, bouse de vache, fumier de porc, etc..
Compost: Decomposed organic matter.
Other Organic Materials: Crop residues, déchets municipaux, boue, etc..

Compound Fertilizer

Our designed disc granulator is also appropriate for producing NPK compound fertilizer, especially in the granulation of rare earth. Aussi, it can make blends of nitrogen, phosphore, and potassium sources to create complex fertilizers.

NPK Elements

Nitrogen elements: urée, chlorure d'ammonium, ammonium carbonate, ammonium sulphate, etc..
Phosphorus elements: SSP, CARTE, DAP, etc..
Potassium elements: chlorure de potassium, potassium sulphate, etc..

2. Feed Materials’ Granulation by Pelletizing Disc

It can make granular additives and supplements used in animal feed production.

Grains and Cereals: Maïs, blé, barley.
Protein Sources: Soybean meal, farine de poisson, bone meal and other protein-rich materials.
Additives: Vitamins, minerals, and other supplements.

3. Biofuel Granulation by Pelletizing Disc

It can make granular biomass materials.

Wood Residues: Wood chips, sciure, bark and other wood residues.
Crop residues like straw and stalks.
Other biomass materials for the production of biomass pellets like bagasse, rice husks.

4. Chemical Powders’ Granulation by Pelletizing Disc

Disc granulators are suitable for processing various chemical powders or granules in many industries, including catalysts, pigments, and additives.

These granules can enhance the flowability and dispersibility of powders, allowing for easier handling and improved performance in downstream processes.

5. Mineral Processing by Pelletizing Disc

Disc granulators have been widely adopted in the mining industry for granulating minerals and ores. They can handle materials such as iron ore, copper concentrate, nickel laterite, and many others. The granules produced are often used as feedstock in the subsequent stages of the production process.

How Does A Pelletizing Disc Work?

Notre usine conçoit le granulateur à disque which transmits powdered materials into the disc by means of the conveyor belt.

We must inform you that, in addition to the equipment’s function, the rate of fertilizer pelletizing is closely related to the humidité, rotary speed, disc angle of inclination, and other factors. These are also conditions for choosing the right disc granulator.

Premièrement, materials are quantitatively added to the disc, and sprayed with appropriate quantity of water.
Deuxièmement, under certain humidity conditions, il roule continuellement pour former un engrais granulaire grâce à l'action de la force centrifuge, friction, et la gravité.
Troisièmement, the particles are attached to other power during rotating and grow gradually.
Enfin, the balls have a specific strength due to the cohesiveness of the material and the water evaporation of the liquid on the ball surface. Then they are discharged from the outlet of the disc.

What Are The Components of The pelletizing Disc?

Le granulateur à casserole consists of many units such as turning disc, scraper, scraper support, engrenages, speed reducer, moteur, movable support, base support, body frame, arbre de transmission, etc.. The entire disc is fixed on the main shaft of the movable support. The electric motor drives the pulley, speed reducer and pinion, and the pinion drives the big gear on the turning disc to make the pelletizing disc work.

The whole machine can be divided into 5 parties:

Partie du cadre

Because the frame supports the transmission part and rotary working part of the disc granulator, it is designed by our company to be welded by excellent channel steel, which can play a very good supporting role for the entire equipment.

Adjustment Part

This part, which is an important aspect of the granulating disc operation, is primarily made of carbon steel plate and channel steel.

Disc Part

Disc granulator adopts the whole circular arc structure, and granulating rate can reach more than 93%. The plate bottom is strengthened by a plurality of radiant steel plates, which is durable and never deformed.

Transmission Part

The transmission part is the core part of the pelletizing disc operation. Both the motor and speed reducer have meet the acceptable quality level. The electric motor drives the pulley, speed reducer and pinion, and the pinion drives the big gear on the turning disc to make the pelletizing disc work. Entre-temps, the big and small gears apply high temperature quenching, strengthening a time of service life.

Automatic Cleaning Part

This device is installed above the pelletizing disc in order to clean the materials stick on the disc wall during the production process.

Why to Choose SX Disc Granulator?

Efficacité de production élevée

Efficacité élevée de production d’engrais

Disc granulator adopts the whole circular arc structure, and granulating rate can reach more than 93%.
The pelletizing disc is equipped with three outlets, making it helpful for intermittent production, reducing labour intensity and enhancing labour efficiency.

Longue durée de vie

The automatic cleaning plate above the disc can remove the sticky material, extending the equipment’s service life and saving labour.
The reducer and motor use flexible belt drive to start smoothly, slow down the impact force and improve the service life of the equipment.
The gears apply high temperature quenching, strengthening a time of service life.

Solid & Reliable Structure

The plate bottom is reinforced with many radiant steel plates, which is strong and durable and never deformed.
It is designed with thick, lourd, and strong base, so it operates smoothly without fixed anchor bolts.
Pelletizer disc is lined with stainless steel to prevent corrosion and keep it durable.

Low Production Cost
