The fertilizer disc granulator is a commonly used granulation equipment in the organic fertilizer production industry. It has the characteristics of stable operation, sturdiness and durability. Its working principle is to add powdered materials to the rotating disc, and then add a water spray device to continuously spray water. Under the action of the rolling friction of the material, the material is made into granules. Different materials have different granulation effects, such as ball formation rate, particle size, and granulation amount.
In the fertilizer industry, the requirements for particle size are not too large, and the size of the pellets is close. Some materials need to be screened after granulation and drying. Some details and skills in the daily use of the equipment will still affect the granulation effect of the disc granulator.
In terms of feed amount, it is necessary to feed evenly, and it cannot be fast or slow. Adjust the nozzle. According to the principle of mechanics, under the same pressure, the nozzle hole is small, the droplet density is small, and the nozzle hole is large, The droplet density is large. Strictly control the amount of water sprayed and adjust the appropriate amount of water to increase the ball formation rate and output. It can also be equipped with a non-powered or powered scraper to assist. The size of the machine, the rotation speed of the disc, and the inclination of the disc are also factors that affect the granulation effect.
The disc granulator adopts an overall arc structure, and the granulation rate can reach more than 93%. The granulation disc is equipped with three discharge ports, which is convenient for intermittent production operation, greatly reducing labor intensity and improving labor efficiency. The characteristics and structure of the organic fertilizer disc granulator are introduced. The reducer and the motor are driven by a flexible belt, which starts smoothly, reduces the impact force of the buffer, and increases the service life of the equipment.
The bottom of the granulation disc is reinforced with multiple radiant steel plates, which is sturdy, durable and non-deformed. The thickened and heavy solid base design does not require anchor bolts for fixing and runs smoothly. The disc granulator is widely used in conveying various non-sticky powder, material or small block materials, such as coal powder, cement, clinker, fertilizer and other materials.
The inclination angle of the large disc is adjustable, and the angle gasket is used for flexible and convenient adjustment. It integrates a unique non-powered combined scraper to reduce auxiliary power consumption; the large disc is composed of a disc body and a disc segment, which reduces the power of the main motor. The disc segment can be adjusted up and down along the disc body, and the end of the disc segment is a flange. Only by clearly understanding the structure and characteristics of the disc granulator can we better use the equipment and identify the problem more promptly once a failure occurs.
