According to engineers from LITO Technology, different types of drum granulation equipment have their own advantages in different application scenarios and requirements. The following are common drum granulation equipment and their characteristics:
Drum granulator
Working principle
The belt and pulley are driven by the main motor and transmitted to the drive shaft through the reducer. The split gear on the drive shaft meshes with the large gear ring fixed on the body, causing the cylinder to rotate. The material is added from the feeding end, and under the special structure inside the cylinder, it sticks and aggregates into balls at a certain humidity and temperature, and then flows out through the discharge port after being made into particles.
Advantages
The ball formation rate can reach 70%, with a small amount of return material and small particle size, which can be re pelletized; It can be heated with steam to increase the temperature of the material, reduce the moisture content after forming the ball, and improve the drying efficiency; Using rubber engineering plastic or acid resistant stainless steel as the lining, the raw materials are not easy to stick to the cylinder and can also prevent corrosion and insulation; Large output, low power consumption, and low maintenance costs.
Scope of application
Suitable for large-scale production of cold, hot granulation and high, medium, and low concentration compound fertilizers, it is widely used in fertilizer production industries such as compound fertilizers and organic fertilizers.
Cylindrical granulator
Working principle
The deceleration motor drives the sprocket to drive the retaining wheel to rotate, and the retaining wheel drives the cylinder with a certain inclination angle to rotate at low speed. Under the action of friction, centrifugal force, and gravity, the mixture rises to a certain height with the cylinder wall and rolls down, rolling into balls in relative motion, and the finished particles are discharged from the lower end.
Advantages
It has the characteristics of high production efficiency, high yield, simple structure, durability, and easy operation and maintenance.
Scope of application
Suitable for industries such as building materials, mining, metallurgy, and chemical engineering, it can pelletize various mixtures.
New Three in One Combination Granulation Equipment
Working principle: Adopting a three combination design, combining the characteristics of organic fertilizer stirring tooth granulator and conversion granulator, and using a new wet continuous push rod granulation process for design and manufacturing.
Advantages: It can pelletize various organic substances, especially coarse fiber materials that are difficult to pelletize with conventional equipment such as crop straw, wine residue, bacterial residue, medicine residue, animal manure, etc. After fermentation, it can also effectively pelletize, and has good granulation effect on raw materials such as humic acid and urban sludge; The shell is made of thickened carbon steel plate welded together, and the supporting equipment includes towing parts, towing wheels, transmission parts, windmills, windmills, etc. The whole machine is sturdy and runs smoothly.
Scope of application: Mainly used in the field of organic fertilizer production, especially suitable for processing materials with complex organic components and high fiber content.
When choosing a drum granulation equipment, it is necessary to comprehensively consider factors such as production scale, material characteristics, product requirements, and investment costs. For example, for large-scale production of compound fertilizers, rotary drum granulators can be given priority; A cylindrical granulator is more suitable for handling mixtures in industries such as building materials and mining; For the complex organic materials in organic fertilizer production, the new three in one combination granulation equipment may have more advantages.
