organic fertilizer production line

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.

First, do a good job in thermal insulation The climate and environment make the transmission parts of various parts start slowly or fail to start due to freezing, which requires that the workplace of the chain type organic fertilizer crusher or the chain type organic fertilizer crusher itself must have certain thermal insulation measures. The raw materials used for the operation of the chain type organic fertilizer crusher must also be subject to antifreeze treatment The moisture of organic fertilizer raw materials is too high, and antifreeze treatment is also critical for the use of organic fertilizer granulator in winter.

Second, use special lubricating oil Low temperature and frequency of use may cause the lubricating oil to encounter freezing and retention, which will affect the lubricating oil supply of the chain type organic fertilizer crusher. Timely adding lubricating oil to this popular chain type organic fertilizer crusher can maintain better use effect.

Third, reasonable maintenance After each work, the chain type organic fertilizer crusher must be checked and maintained, mainly focusing on the drive part, lubrication part and residual material cleaning. The maintenance is the basis for the use of the chain type organic fertilizer crusher in winter In addition, the failed parts of the organic fertilizer chain crusher shall be replaced in time to avoid the operation of the organic fertilizer chain crusher with problems, reduce the production and use costs caused by the machine failure, and the reasonable maintenance shall also be completed regularly to ensure the maintenance and attention of each component in order to make the organic fertilizer chain crusher show a better effect.

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.

The double roller granulator is produced by non drying normal temperature process, and is formed at one time. The equipment has less investment and good economic benefits.

The complete set of equipment is compact, scientific and reasonable, and technologically advanced. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials, with high granulation rate.

The double roller granulator is the key equipment for compound fertilizer granulation. It is advanced in technology, reasonable in design, compact in structure, novel and practical, and low in energy consumption. It forms a small production line with corresponding equipment. It can form a continuous, mechanized production with a certain capacity, without drying, and under normal temperature. The product is rolled and shaped at one time to make the product quality meet the requirements of compound fertilizer technical indicators. It is used to produce high, medium Low concentration special compound fertilizer and the updated products for energy conservation and consumption reduction in the compound fertilizer industry.

Capsule filling particles, pigments, detergents, catalysts, strontium carbonate, chemical fertilizers, white carbon black, inorganic salts, chlorides, cyanuric acids, pesticides, oxides, etc., as well as industrial recovered dust materials: such as iron foundry dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust, etc The material is forced into shape by mechanical pressure, without any wetting agent, and the product purity is guaranteed.

The production process of double roller granulation is short, with low energy consumption and large output The dry powder is directly granulated, without the need for subsequent drying process, which is more conducive to the connection and transformation of the existing production process. The particle strength is high, and the increase of bulk specific gravity is more significant than other granulation methods. It is especially suitable for the occasion of increasing the bulk weight of products. The operation flexibility is large and the adaptability is wide. The extrusion force can be adjusted by hydraulic pressure.
