What are the characteristics of the process flow of the double roller granulator?
Flow chart of double roller granulator
The raw materials are evenly fed into the hopper through the quantitative feeder. The compactor uses pairs of rollers with holes to leave a certain gap with each other. The two rollers rotate in reverse direction at the same speed. One group of roller bearing blocks is immobile in the frame, while the other group of roller bearing blocks is moved on the guide rail of the frame, which is pressed by the hydraulic cylinder to make them close to each other. There are many holes with the same shape and size regularly arranged on the roll surface, and the wave trough is aligned with the wave trough. At this time, the dry powder material continuously and evenly enters between the two rolls by self weight and forced feeding from the top of the two rolls of fertilizer granulation machine. The material flows freely first, enters the bite zone, and then is gradually bitten into the trough by the rolls. With the continuous rotation of the roll, the space occupied by the material is gradually reduced and gradually compressed, reaching the maximum forming pressure. Then, the pressure gradually decreases, and the pressed block falls off due to its elastic recovery and self weight, and enters into the crushing and screening device. The finished product is qualified granular product and is weighed and packaged. The fine powder and unqualified super large particles from the powder outlet will re-enter the feeding port of the hoist by the return auger, and will be mixed with fresh materials and added into the pre feeding hopper to enter the next round of process flow.
Characteristics of double roller granulator
The dry powder is granulated directly without any additives;
The particle strength can be adjusted, and the finished product strength can be controlled by adjusting the roller pressure;
Circulation operation, continuous production and high output of finished products;
The material is 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 convergence and transformation of the existing production process.
It is especially suitable for increasing the bulk density of products
The organic fertilizer granulation machine can adapt to a wide range of raw materials, and the particle strength can be adjusted freely according to different materials.
It 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, can realize one person multi machine control, low labor intensity and long-term continuous operation.
The main transmission parts are made of high-quality alloy materials. It is made of stainless steel, titanium, chromium and other surface alloys, which greatly improves the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, so that the machine has a long service life.
