What is the difference between a drum granulator and a disc granulator machine?

 Common organic fertilizer granulators on the market include: double roller granulator, drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, all kinds of granulators have their own production characteristics, and the prices of granulators vary. Both the drum granulator and the disc granulator can be used in the organic fertilizer production line and the npk production line. Are there any differences and characteristics between the two?


The main advantage of the rotary drum granulator is to use steam to heat and adjust the humidity, which reduces the load on the dryer. The granulation rate of the drum granulator can reach 70%. By increasing the granulation temperature and increasing the liquid phase in the base material, the material is promoted to form a spherical shape at a low water content. It has the advantages of easy drying, energy saving and consumption reduction. When the process conditions are not well controlled, the return material is higher than that of the disc granulator.

The disc granulator adopts arc structure, and the granulation rate can reach more than 95%. The disc is equipped with three outlets, which is convenient for intermittent production operations. The reducer and motor of the disc granulator adopt flexible belt transmission, which can start smoothly and reduce the impact force. The bottom of the pot is reinforced with multi-layer radiant steel plates, without anchor bolts, which is durable. It has the characteristics of uniform granulation, less recycled materials, and large production capacity. However, material pretreatment cannot be carried out, and dust and smoke pollution are serious.

The fertilizer granulator produced by our factory has complete specifications and high quality, and all the indicators have reached or exceeded the national standard. After fermentation, it can be made into powder or granular fertilizer. It has realized the one-stop service of design, manufacture, installation, commissioning and technical training. Welcome to contact us for details.

The importance of organic fertilizer equipment to agricultural production

Image
  Organic fertilizer equipment   can be divided into two categories according to the working principle and functional characteristics of organic fertilizer fermentation equipment and organic fertilizer production equipment. Organic fertilizer fermentation equipment mainly includes organic fertilizer fermentation compost machine, organic fertilizer fermentation pile turning machine, organic fertilizer fermentation heat storage equipment, etc. Its working principle is to control ventilation, stirring, heat preservation and other operations, so that organic matter under certain conditions decay, fermentation, decomposition into organic fertilizer. The organic fertilizer production equipment includes organic fertilizer grinder,  organic fertilizer granulator , organic fertilizer dryer, etc., the main work is to crush, shape and dry raw materials, so that it becomes an organic fertilizer product that is easy to store, transport and apply. Organic fertilizer equipment plays an important role

How much moisture is required for organic fertilizer granulation?

Image
  Organic fertilizer granulator   in the whole process of production and processing, the material is required to have a certain viscosity , and some raw materials are loose after fermentation, and it is not easy to granulate, so it is necessary to add some water or adhesive to improve the viscosity of the material.  Disc granulator   and wet test granulation, water or adhesive will be added in the whole process of granulation to ensure that the material can be fully granulated. The  new  type  organic fertilizer granulator  uses wet test granulation, and the material after fermentation can be granulated immediately, without the operation process of other production processes. The roller extrusion granulator adopts the production process without boring and tasteless at room temperature, and the granulation of materials with relatively low viscosity can be used. If the moisture content of the material is too high, you can moderately add some dry materials to melt the moisture content. If

Why is organic fertilizer equipment more and more popular with farmers?

Image
  Organic fertilizer equipment   is widely used in agricultural production, which can not only treat agricultural waste, but also produce high-quality organic fertilizers to meet the needs of different crop growth. Organic fertilizers produced by organic fertilizer equipment can not only improve soil fertility, improve soil structure, but also promote crop growth and improve the quality of agricultural products. Organic fertilizer produced by organic fertilizer equipment contains rich trace elements and organic matter, which is not easy to lose, and can improve soil fertility for a long time. Secondly, the use of organic fertilizers can reduce the dependence of the soil on chemical fertilizers, reduce the pH of the soil, and reduce soil pollution. In addition, organic fertilizers promote the growth of soil microorganisms, which contributes to the formation of a healthier ecosystem. Organic fertilizer equipment not only has environmental protection value, but also has important sustaina
