The principle of fertilizer granulator granulation is the process of material layer by layer wrapping, which requires a core. With a core, particles have a certain strength matrix, and particles are less prone to deformation. If all of the particles are produced with new materials, no returns or very little returns, and there is no core, the liquid phase will increase when encountering high temperatures, making the particles appear particularly soft. In addition, the internal copying board of the equipment will copy the particles to the top and drop them vertically, causing the originally round particles to fall into a round and flat shape. To change this situation, first lower the temperature of the dryer to reduce the solubility of the material; The second is that there must be enough in the return volume Ф 1-2 mm small particles.

If the formula is not reasonable, excessive use of viscous fillers can also cause particles to be out of round. When using PVC lining inside the fertilizer granulator, each shift must shovel all the accumulated materials inside (tools such as shovels cannot damage the smooth surface), and adjust the tilt angle to the appropriate level. The smoothness and sphericity of the product are still good. The roundness of particles is a quality indicator that every factory attaches great importance to. In the production process, the more round the particles are made, the higher the output, so it is also higher. Therefore, most manufacturers consider the roundness of their own products as a key content of technical research and an important indicator of measuring the technical level of a complex factory.

The formation process of high concentration composite fertilizer particles is as follows: initially, small particles with a diameter of 1~2mm in the returned material are used as the core. Under the conditions of 60~650C temperature and appropriate liquid phase, under the rolling of the powder material and mechanical power, the particles are wrapped layer by layer to form soft particles with a diameter of 2~4mm. Then, the moisture of the material gradually evaporates in the dryer, and the soft particles gradually solidify, forming normal particles with a certain strength.

The liquid phase exceeds the standard, and the powder content is low during the granulation process of the fertilizer granulator. The particles lack a flat and filling powder material during rolling. Therefore, the moisture inside the granulator should be controlled to be dry, as long as it causes Ф 1-2mm particles are recommended and should not cause damage Ф 2-4mm qualified particles. Due to the excessive liquid phase, there is material bonding and large particles on the lifting plate and cylinder wall inside the dryer. Due to the lack of smooth conditions in the dryer, the particles will be irregular.

A small amount of finished products and excessively high drying temperature can also cause particle breakage and the formation of irregular particles.

The general manufacturing process of organic fertilizer includes organic matter inoculation fermentation (pre-fermentation), main fermentation, crushing, compound mixing, drying, granulation (disc granulator machine, npk fertilizer granulator, etc.), cooling, sorting, sorting, including Weigh and pack.

Semi-wet material crusher is a professional equipment with many years of experience and advanced crushing technology at home and abroad. This machine completely solves the problem of crushing organic matter with high moisture content. It is a national initiative and has been declared a national patent. The successful development of this machine has played an important role in reducing the production process of bio-organic fertilizer and compost, reducing capital investment and saving operating costs. The moisture of this machine used for biological fermentation of organic fertilizer is 25-50%, and the particle size after crushing meets the requirements of granulation. The organic fertilizer made from municipal waste has a crushing effect on glass, ceramics, bricks, gravel, etc., and is safe to apply.

Installation and debugging of semi-wet material crusher:

1. Install on a horizontal concrete foundation and fasten with anchor bolts.

2. Pay attention to the vertical and horizontal directions of the host during installation.

3. After the installation is completed, check whether the bolts of each part are loose, and if they are loose, they should be tightened.

4. Configure the power cord and control switch according to your device power supply.

5. After the inspection, carry out no-load test drive.

What should I do if the semi-wet grinder is blocked during use?

During the working process of the semi-wet raw material crusher, the wet raw materials are finely crushed and then stick together. The fibers of the material are so strong that they won’t break easily even when hit with a hammer. The phenomenon of material blocking may also be caused by the high discharge pressure and the failure of the intake valve at the bottom of the crushing chamber to open. Improper operation of employees, etc.

Manure biomass organic fertilizer equipment supporting facilities need fermentation turner, organic fertilizer pulverizer, drum screening machine, horizontal mixer, organic fertilizer equipment disc granulator, organic fertilizer fermentation equipment to explore the reason for the deterioration of the soil layer Professional knowledge rotation Drying equipment, cooling machine, screening machine, outer film machine, automatic packaging machine, belt conveyor and other machinery and equipment. Commonly used granulation equipment for organic fertilizers are: disc granulator machine, npk fertilizer granulator, drum granulator, wet granulator, roller extrusion granulator, flat die granulator, ring film granulator granulator. If the shape requirements of the granules are different, the processing process of the organic fertilizer production line is also different, and the fertilizer granulator machine price is also different.

1. The disc granulator machine is powered by a motor to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it rolls down by itself, and rolls into particles like a snowball. Suitable for non-sticky powdery materials.

2. The bottom of the disc organic fertilizer granulator is strengthened by a number of radiant steel plates, which are durable and permanently fixed. The organic fertilizer disc granulator has a thickened, heavier, and solid base decision, without anchor bolts, and runs smoothly.​​

3. The disc granulator machine is relatively small, the production capacity is low, and the price is relatively cheap, generally 30,000 to 50,000 yuan;

4. The control of water content in the operation of the disc granulator of organic fertilizer equipment. When the disc granulator is running, the inclined disc granulation process is adopted. The pelletizing process requires high moisture content, and poor moisture control can lead to a decrease in pelletizing speed. Therefore, during the processing, attention should be paid to observe the moisture control changes of the granulated raw materials with a sprayer.

The products produced by the sludge composite fertilizer production line configuration are made from fresh chicken and pig manure as raw materials, without any chemical components. However, the digestion ability of chicken and pig is poor, and only 25% of the nutritional components can be consumed. The other 75% of the nutritional components in the feed are discharged with the manure, resulting in dry products containing organic matter, amino acids, proteins, and other components.

The main equipment of the compound fertilizer equipment production line adopts forward and reverse operation, and uses a special internal spiral mechanism and unique three-dimensional structure to mix and output materials. The entire equipment has the characteristics of low price, small footprint, large output, and even mixing.

The compound fertilizer equipment production line is designed and manufactured according to the requirements of compound fertilizer factories and fertilizer distributors, with a production capacity of 1-100000 tons. It adopts a process of direct feeding from the lifting tank and direct unloading from the mixer, almost achieving the goal of “zero” feeding.

The product configuration of the compound fertilizer equipment production line includes raw material conveying system, ingredient metering system, material mixing system, product packaging system, and high-performance control system. This equipment overcomes the phenomenon of mixture chromatography or separation caused by different raw material densities and particle sizes, and improves the accuracy of batching.

The compound fertilizer equipment production line solves the impact of factors such as material characteristics, mechanical vibration, air pressure, voltage fluctuations, and cold weather on the system. It has the characteristics of high accuracy, fast speed, and long service life, making it an ideal choice for compound fertilizer (mixed fertilizer) manufacturers This equipment has multiple models to choose from, with a production speed of 6-18 tons/hour and 3-8 types of raw materials.

Unfermented chicken manure and cow manure belong to the category of farmyard manure. The unfermented raw material contains a lot of heavy metals, insect eggs, weed seeds, and other harmful bacteria. If it is not cleaned in time, it will produce unpleasant odors and pollute the air.

The resource utilization of manure through organic fertilizer equipment can not only reduce environmental pollution, but also improve the biosafety level of breeding enterprises, reduce the prevalence of infectious diseases of livestock and poultry, and produce high-quality organic fertilizers. On the one hand, the profit has doubled, and the rural economy has embarked on the fast track of “safe, environmentally friendly and efficient” development.

Factories with an annual output of less than 5,000 tons belong to small-scale processing. Small-scale organic fertilizer production lines are mainly divided into two types: powder lines and pellet lines. The complete set of equipment for the production line of small organic fertilizer equipment is the same as the large equipment, but the magnitude parameters are different. The same are: fermentation equipment, crushing equipment, mixing equipment, organic fertilizer granulator（npk fertilizer granulator,disc granulator machine,etc）, drying and cooling equipment, screening equipment, coating equipment and packaging equipment, the fertilizer granulator machine price varies with different equipment configurations, and the same is true for other equipment. Powder line can not use granulator equipment.
