The invention has wide adaptability to raw materials and can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, coal, metallurgy, etc. It can also produce various concentrations and types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.).
4. Double roll extruding granulator, especially rare earth, ammonium bicarbonate and ammonium sulfate compound fertilizer.

Working principle of the double roller press granulator: the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and work in reverse synchronization with the driven shaft through the split gear. The material is added from the feed hopper, demoulded and granulated by double roll extrusion, and then transported to the crushing chamber through a pair of chains for crushing. The finished granules (balls) are separated under the screen, and the returned materials are mixed with new raw materials for granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production is realized.

What benefits does the organic fertilizer Crusher bring to the environmental pollution? As China’s agricultural production relies excessively on fertilizer and other fertilizer sources, the soil structure has changed. The existence of these problems, to a certain extent, threatens the area of a small number of cultivated land in China. The country has always attached great importance to them. Through research and practical tests, it is found that the organic fertilizer produced by the organic fertilizer production line can alleviate the problems of soil compaction and salinization due to its rich nutrients and organic matter content, which is a necessary fertilizer source for the country to carry out sustainable agriculture and build ecological agriculture. Therefore, the organic fertilizer production line has been strongly supported by the state.

The organic fertilizer Crusher is specially designed for crushing organic fertilizer and compound fertilizer. After the materials enter the crusher through the feed port, they are crushed into materials that can pass through the radial clearance and discharged through the discharge port. The inner wall is made of rubber or stainless steel (depending on the customer’s needs), which makes the surface smooth and easy to clean. It changes the phenomenon that the inner wall of ordinary grinder is rough, easy to accumulate powder, and difficult to clean, so that the production of food, medicine, chemical industry, etc. is more in line with national standards and GMP sanitary requirements. During the crushing process of the organic fertilizer chain crusher, high-strength cemented carbide chain plates with synchronous speed are used. The inlet and outlet design is reasonable, the broken materials are uniform, not easy to stick to the wall, and the cleaning is convenient. The crusher adopts the latest technology, selects high-quality steel, and carries out system optimization design, with large output and high reliability. The organic fertilizer chain grinder has the characteristics of reasonable structure, fast feeding, stable performance and strong impact resistance.

China has a vast territory, and its natural conditions, agricultural production methods and economic development levels vary greatly from region to region. These conditions have a great impact on the utilization of manure resources. It is of positive significance to promote the comprehensive utilization of livestock and poultry manure resources by summarizing the experience and problems of existing farms in using manure resources and exploring a manure resource utilization model suitable for the characteristics of various regions.

Our trough compost turning machine is suitable for the fermentation of livestock manure, sludge and garbage, filter sludge from sugar factory, straw and sawdust and other organic wastes. It is widely used in the fermentation, decomposition and moisture removal of organic fertilizer plant, compound fertilizer plant, sludge and garbage plant, horticultural field and Agaricus bisporus planting plant.

Compost turner machine is suitable for all kinds of materials

Advantages of compost turner products:

1. Low energy consumption oforganic fertilizer roller granulator: extrusion granulation is the granulation of materials at room temperature. Compared with other granulation methods, it does not require drying measures such as fuel oil and gas. The production only requires power consumption and a small amount of cooling water (for roller shaft cooling), and the power consumption per ton of product is only about 30 kW/h.
2. There is no need to add adhesive to the organic fertilizer roller granulator: other granulation processes are basically wet processes, which must have a drying process, with high energy consumption and high product moisture. However, dry granulation does not require additional additives, but only uses the intermolecular force of the material itself, simplifying the process and reducing energy consumption.
3. The investment of theorganic fertilizer roller granulatoris low: because the drying process is omitted, and the return ratio is low (accounting for about 35% of the total feed of the extruder), the process flow is simple and the investment is low.
4. Wide range of applicable raw material particle specifications: extrusion granulation has no special requirements on the particle size of raw materials. Both 1~4mm granular materials and fine powder materials can be used. Unqualified powder materials and powder products can be better used, and the cost can be reduced by using powder materials.
5. Wide capacity range oforganic fertilizer roller type extrusion granulator: for the extrusion granulator, the effect of economic scale is not obvious, and the unit capacity of 1~50 t/(h. set) can be economically designed, so the applicable capacity range is wide.

The only disadvantage of producing granular fertilizer by roller extrusion granulation is that the product shape is irregular particles, but the irregular particle shape has no effect on the application of fertilizer, and the dressing process can be added to further round the particles. The fertilizer produced by extrusion granulation has sufficient strength, less dust, no agglomeration, narrow particle size distribution range, and good fluidity, so it has good economic benefits.

Fertilizer dryer is suitable for the processing of organic fertilizer and NPK production line, and each structure of it is very important. Organic fertilizer dryer also has certain technical requirements when processing. So, what should be paid attention to when drum dryer is producing organic fertilizer?

How to effectively protect fertilizer equipment against aging and deformation. NPK production line equipment factory here to share a little tips.

There are differences in the composition and properties of organic fertilizer materials, so there are also differences in the effects of organic fertilizer on Soil and crops. Therefore, according to the texture of soil, climate, growth habit and fertilizer demand of crops, we should choose the appropriate organic fertilizer for rational fertilization. For example: human feces and urine contain a large number of chloride ions, which should be avoided for crops that do not like chlorine nutrients.Now,the organic fertilizer is to be produced and to be used in the agriculturial industry.In the fertilizer manufacturing process,using different type and series organic fertilizer machine to finish the production process.How to use the organic fertilizer machine to make organic fertilizer?

Firstly,we talk more about the reason why we use the organic fertilizer?
The more organic fertilizer  is used,the better.Organic fertilizer is large in volume and low in nutrient.It needs a lot of application to meet the growth needs of crops,but not more is better.Because organic fertilizer,like chemical fertilizer has the problem of quantitative application in agricultural production.If a large amount of organic fertilizer is used,it will not only waste,but also cause soil obstacles and affect the growth development of crops.For example,in the cultivation of protected land,if a large amount of organic fertilizer is applied for a long time,it can also lead to excessive nutrient elements in the soil and salinization of the soil,resulting in poor growth of agricultural products,excessive nitrate content,quality degradation and other problems.Therefore,the application amount of organic fertilizer in production should be reasonably used according to the consumption of various nutrients and organic matter in the soil,so as to achieve formula fertilization and scientific fertilization.
Then the organic fertilizer manufacturing process is not so complex by using the organnic fertilizer machine.In the line,by using the automatic or semi-automatic fertilizer machine to finish the production process can save more complex process.Like using the fertilizer granulator machine to make organic fertilizer granulator,which we can use the rotary drum granulator or the disc granulator machine to make organic fertilizer to be granulator directly.And using these automatic or semi-automatic fertilizer machine also improve the working efficient.
Finally,we talk a little the application method of the organic fertilizer.The organic fertilizer shall be applied by trenching or digging holes for centralized fertilization,and the soil shall be covered in time after application;if it is applied by sprinkling,it shall be turned into the soil after application.Generally,organic fertilizer and chemical fertilizer are mixed for better effect.If superphosphate is mixed with organic fertilizer,the fertilizer effect can be greatly improved.

With the wide application of organic fertilizer dryer equipment, many customers reported that after using the organic fertilizer dryer equipment for a period of time, it will produce strong vibration and noise, which will do great harm to operators and the surrounding environment. As the manufacturer of organic fertilizer dryer equipment, here we take the rotary dryer as an example to introduce several good methods to effectively reduce noise.

1. Add sound insulation cover. The whole rotary dryer is closed with steel structure skeleton, thin steel plate as shell, damping layer plastered inside and filled with ultra-fine glass wool or other sound absorbing materials. As the rotary dryer generates a lot of heat during operation, attention must be paid to solving the problems of heat dissipation in the hood and facilitating equipment maintenance.
2. The noise level can be reduced by 9dB (A) if the manganese steel lining plate is replaced by the rubber lining plate, and the frequency spectrum characteristics also change from high frequency to low frequency.
3. Set the elastic layer. A heat-resistant soft rubber pad is laid between the inner surface of the drum of the rotary dryer and the lining plate. In order to prevent the soft rubber pad from overheating, an industrial felt with a thickness of 10-15mm is laid between the lining plate of the dryer and the soft rubber pad, which can reduce the noise of the rotary dryer below the standard.
4. Wrap the sound insulation layer outside the drum wall. Wrap a layer of 50mm thick industrial felt outside the drum wall of the rotary dryer, use the 1. smm thick steel plate as the protective surface, and fix it on the drum wall with bolts. The actual sound insulation value is about 12dB (A). If the two ends of the drum are also treated in the same way, the joint of the drum wall binding shall be well sealed, and the sound insulation effect may also be improved.
5. Sound insulation room is designed. If conditions permit, therotary dryerroom will be transformed into a special sound insulation room, which will be better than the sound insulation cover. However, attention must be paid to solving the problems of monitoring, indoor heat dissipation and maintenance during the operation of the rotary dryer.

Improve the working efficiency of organic fertilizer crusher

1. The selection of materials is the key. When selecting materials, pay attention to the hardness of materials. The harder the material is, the more difficult the equipment is to crush and wear. The crushing speed is slow and the natural crushing capacity is small.

2. The humidity of the material is the key. When the water content of the material is large, the material is easy to stick in the grinder, but it is also easy to block during the feeding process, thus reducing the crushing capacity. Therefore, the water content should be reduced as much as possible before crushing so that the grinder can operate better.

3. Crushing materials require high fineness, that is, the finer the material, the smaller the crushing capacity.

4. Composition of crushing materials: The more fine powder content in the materials before crushing, the greater the impact on crushing, because these fine particles are easy to adhere and affect transportation. The content of fines shall be pre screened.

5. Viscosity of materials: that is, the greater the viscosity of materials, the easier the bonding.

6. The better the abrasion resistance of the crushing parts (hammers and jaw plates) of the crushing equipment, the stronger the crushing capacity. If they are not abrasion resistant, the crushing capacity will be affected. For example, crushed straw can be made into organic fertilizer, which can destroy farmland and greatly improve the use efficiency based on farmland.
