Application of organic fertilizer granulator

According to the different granulation modes, it is generally divided into the following types.

1. Disc granulator

It is composed of inclined granulating disc, driving device, frame of disc inclination angle adjustment mechanism, feeding pipe, material liquid sprayer, scraper and so on. The angle of inclination is 35-55 degrees, and the rotational speed is n=10-18r/min. The smaller the angle, the longer the residence time and the larger the particles. Huaqiang disc granulator is widely used in organic fertilizer production enterprises due to its small investment in equipment and low operating costs.

The disc granulator is mainly used for ball granulation with good cohesion and powder homogeneous material; disc structure and gear transmission. Production capacity: 1.0 ~ 3.0 tons/hour; the ball forming rate is over 70%; the material is required to be fine, and it needs to pass through a 20-mesh sieve; power: 7.5 ~ 15 kilowatts.

For fermented materials with more crude fiber raw materials, this equipment is more suitable for fermented raw materials that are mainly powdery materials. If disc granulation equipment is used, it is recommended to pulverize twice, otherwise, it will directly affect the granulation quality.

2. Roller extrusion granulator

It is suitable for making soluble or non-sticky granules, especially for chemical fertilizer granules. It is not suitable for organic fertilizer granulation of sticky rice husk chicken manure with a certain water content. It is easy to block the mold hole. The mold hole needs to be cleaned regularly, resulting in the consequence of not being able to work continuously. It is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product has a high granulation rate.

3. Flat die extrusion granulator

It is suitable for granulation of phase-coarse fermentation organic fertilizer. It is mainly suitable for granulation of crude fibers, such as: sawdust, rice husks, cotton stalks, cottonseed husks, weeds and other crop straws, household garbage, wastes from waste plastic boxes factories, and granulation of materials with low adhesion rate and difficult to carry out. , briquetting, bar making, and also suitable for low-temperature granulation of biological bacterial fertilizer, organic fertilizer, compound fertilizer, etc. Production capacity: 1.0~4.0 tons/hour; ball forming rate is more than 95%, less return material; power: 22~90 kilowatts.

Due to the large extrusion strength of the flat die granulator, the granulation template is sometimes destroyed, and sometimes the hole of the granulation template is blocked, requiring additional equipment care and replacement of consumables.

4. New Organic Fertilizer Granulator

A new type of organic fertilizer granulator, also known as organic fertilizer wet granulator. The equipment utilizes the mechanical stirring force of high-speed rotation and the resulting aerodynamic force to continuously realize the process of 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 greater than or equal to 0.7, the particle size is generally between 0.3 and 3 mm, and the granulation rate is greater than or equal to 80%. The higher, the smaller the particles, and vice versa. The tooth stirring granulator has high granulation efficiency, spherical particles have no acute angle after granulation, and the pulverization rate is low, which is easier to meet the requirements of large-scale and production. The power is generally around 37 kilowatts.

5. Drum granulator

A drum granulator is a molding machine that can make materials into specific shapes. Rotary drum granulator is one of the key equipments in the compound fertilizer industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of agglomerates. Through the amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after humidity adjustment. Under the condition of the liquid phase, the rotation of the cylinder makes the material particles squeeze Forces reunite into balls.

6. Dry rolling granulator

In the dry rolling granulator, the dry powder material is added from the top of the equipment, degassed and spirally pre-pressed into the counter-roller, and the material is plastically deformed and compressed into a sheet under the action of the extrusion force of the counter-roller. The flaky material is then subjected to processes such as crushing, granulation, and screening to obtain granular products. Features ·The material is forced to be compressed by mechanical pressure without adding any wetting agent, and the product purity is guaranteed.
