Compound fertilizer production

Do you know about the dobule roller granulation machine?

The double roll extrusion granulator is mainly used for the granulation of organic fertilizer and compound fertilizer. The opposite roller extrusion production line is not used for drying and cooling process for the granulation of inorganic fertilizer, which saves a certain amount of cost. In the rapid development of fertilizer industry, the non drying production line is welcomed by customers due to the impact of environment.

How to distinguish single shaft and double shaft roll extrusion granulator?

The single shaft double roll extrusion granulator, the motor drives the belt and pulley, which are transmitted to the driving shaft through the reducer, and synchronized with the passive shaft through the split gear, working in opposite direction.

The belt and pulley are driven by the motor and transmitted to the two output shafts of the reducer through the reducer, and each output shaft drives the two grinding rollers to do opposite work through the coupling.

The double axis extrusion granulator is divided into uniaxial and biaxial. The density of biaxial extrusion material is 1-1.5 times higher than that of uniaxial extrusion material, that is to say, the particle strength produced by the double shaft twin roll extruder is significantly higher than that of the uniaxial extruder. In addition, the output is also increased by 0.5 times, and the granulation rate reaches more than 95%, and the particles are nearly round. After being shaped by the drum throwing round machine, it can be used as compound fertilizer The roundness of the particles is comparable.

Double roller extrusion fertilizer granulation machine

The shape and size of the ball and socket on the roller skin of the double shaft double roller extrusion granulator can be selected in a wide range according to the user’s needs. The ball pressure shapes include pillow shape, semi-circular shape, shape, walnut shape, flat ball shape and square bar shape. At present, the shape of flat ball is adopted.
The whole machine is divided into four parts: frame part: transmission connection part, head working part and crushing and separating part.

This series of double roller granulation belongs to extrusion sliding model. Its working principle is that the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and work in opposite direction with the driven shaft through the split gear. The materials are added from the feeding hopper, extruded by rollers, demoulded and pelletized, and transported to the crushing Screen Studio through a pair of chains. The finished products (balls) are screened and separated, and then the returned materials are mixed with the new materials, and then granulated. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

Compound Fertilizer Double Roller Extrusion Granulation Production Line

For ammonium chloride extrusion granulation, the double roll extrusion granulator is selected. The roll skin of double shaft twin roll extrusion granulator is made of high-quality anti-corrosion and wear-resistant materials. It has the advantages of beautiful appearance, simple operation, low energy consumption, long service life and high granulation rate. The roller skin of this series of twin roll extrusion granulator is widely used in compound fertilizer manufacturing process.

New Type Vertical Crusher – strong adaptability and wide application.

Overview of new type vertical grinder.

Nowadays, this new type crusher is suitable for a wide range of raw materials, such as organic fertilizer, bio organic fertilizer, compound fertilizer and so on. In the grinding process, the high-strength wear-resistant cemented carbide chain, blade and vertical head with synchronous speed are adopted. The design of the feed inlet of the crusher is reasonable, the crushing material is uniform, and the raw material with large moisture content is not easy to stick to the wall, and the crusher cleaning is convenient The chain mill is suitable for crushing materials with moisture content of about 20% ~ 50%. It is the first choice for fermentation raw materials.

Advanced design of new type vertical crusher.

After technical improvement, the configuration and quantity of hammer pieces are improved, so that the crushing effect of materials is better, the angle setting of feeding port is improved, and the feeding port is no longer sticky.

The outlet setting is improved and the air outlet is increased. When the dust is large, the dust can be removed to reduce the dust pollution in the production workshop. The allowable moisture value of organic fertilizer material for biological fermentation by vertical chain mill can reach 25% – 50%, and the crushing particle size can meet the requirements of granulation.

The grinding degree can also be adjusted within a certain range according to the needs of users. It grinds hard materials such as glass, ceramics, bricks and gravel in the organic fertilizer of municipal solid waste and achieves the effect of safe use. This machine can shorten the technological process, reduce equipment investment and save operation cost for organic fertilizer and compost production. It is an ideal machine for fertilizer production and processing units.

The motor drives the main shaft to rotate. The main shaft has two bearing seats, which are installed at the upper and lower ends of the casing. The casing assembly is installed on the lower frame, the main shaft is equipped with a rotor disc and chain, and the feeding hopper is on the upper part of the casing. In order to facilitate the loading and unloading of the hammer head, a valve is opened on the casing to facilitate disassembly and repair.

New Type Organic Granular Fertilizer Production Line

Application of new type vertical grinder.

1. Composting. You can use this machine to deal with manure, biogas residue, household waste, etc. during composting.
2. Organic fertilizer granule production line. Before granulation, in order to avoid the influence of large particles on granulation, you can use this pulverizer to process raw materials.
3. Compound fertilizer granule production line. Similarly, in the compound fertilizer pellet production line, this crusher can help you process raw materials and return materials.

What machines do you need to process compound fertilizer?

Introduction of the compound fertilizer production line

The compound fertilizer production line adopts the non-drying room temperature process production, one-time molding, the output is 1-2t/h, the compound fertilizer production line equipment investment is small, the effect is fast, and the economic benefit is good. The complete set of compound fertilizer equipment (click here to get) has a compact layout, scientific and reasonable flow, advanced technology, energy saving and consumption reduction, no three wastes, stable operation, reliable operation, convenient maintenance and wide raw material adaptability.

It is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce compound fertilizer of various concentrations and various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) .

Compound fertilizer equipment characteristics: Compound fertilizer equipment is suitable for the direct production of crude fiber organic wastes with a moisture content of about 30%, such as fermented livestock and poultry manure, sugar factory filter sludge, urban sludge, paper sludge, distiller’s grains, straw, and peat. It can produce pure organic fertilizer, organic and inorganic fertilizer, and biological organic fertilizer of spherical particles.

The compound fertilizer equipment has a high ball formation rate and biological bacteria survival rate. The new technology can make the ball formation rate reach more than 90-95%. The new technology of low temperature and large air volume drying in the compound fertilizer production line can make the microbial bacteria survival rate reach more than 90%.

The compound fertilizer equipment has a short process flow and low operating cost. The organic raw materials used in the process do not require pretreatment such as drying and crushing. The process flow is short and the operating cost is low. (If traditional granulation processes such as discs or drums are used, post-fermentation Organic raw materials with a moisture content of about 30% are dried to below 13%, crushed to above 80 mesh, and the amount of organic materials added cannot be greater than 30%).
