The double roller granulator produced by our company uses the latest rolling control technology. The control equipment of the fertilizer granulator
can adjust the fluctuation of any physical properties (such as local unevenness) between different materials and different batches of the same material, so that the process parameters (such as processing capacity, sheet density, rolling pressure, speed, etc.) of dry granulation can be precisely and repeatedly adjusted, Thus high quality particles can be produced efficiently.
The double roller granulator
uses the dry rolling technology to compress the powder materials with water content ≤ 15% into pieces or blocks, and then through the crushing and screening process, the pieces and blocks of materials become the granular materials that meet the use requirements. The dry double roller granulator mainly relies on the external pressure mode, so that the material is forced to pass through the gap between two relative rotating rollers and compressed into pieces. During the rolling process, the actual density of the material can be increased by 1.5 to 3 times, so as to meet certain particle strength requirements.
Characteristics of double roller granulation process
◆ in the fertilizer production line
, without any additives, dry powder is directly granulated;
◆ the particle strength can be adjusted. The strength of the finished product can be controlled by adjusting the pressure of the roller;
◆ circulation operation to realize continuous fertilizer production line with high output of finished products;
◆ the material is forced compressed by mechanical pressure, without any additives, and the purity of the product is guaranteed.
◆ direct granulation of dry powder, without subsequent drying process, is more conducive to the connection and transformation of the existing production process.
◆ the particle strength is high, and the increase of packing proportion is more significant than other granulation methods, especially suitable for the occasion of increasing the packing proportion of products.
◆ the double roller granulator can adapt to a wide range of raw materials, and the particle strength can be adjusted freely according to different materials.
◆ in the roller granulation fertilizer production line, the fertilizer granulator has compact structure, convenient maintenance, simple operation, short process flow, low energy consumption, high efficiency and low failure rate.
◆ it can control environmental pollution, reduce powder waste and packaging cost, and improve product transportation capacity.
◆ the feeding and feeding device adopts frequency conversion stepless adjustment control, with high degree of automation, which can realize the control of one person and multiple machines, and has the characteristics of low labor intensity and long-term continuous operation.
◆ the main driving parts of the double roller granulator are made of high-quality alloy materials. Stainless steel, titanium, chromium and other surface alloys greatly improve the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, so that the machine has a long service life.
