What are the structure and characteristics of dry rolling granulator?

Dry rolling granulator is a new type of granulator that uses dry powdered organic fertilizer as raw material. The equipment adopts dry rolling technology, which can pass dry powdered organic fertilizer with a moisture content of ≤10% through the external The pressurized method is used to make granular organic fertilizers with a specific shape, which can generally eliminate the subsequent drying and cooling links. Let’s work with Tongda Heavy Industry, a manufacturer of organic fertilizer granulator, to understand the specific structure and characteristics of the dry rolling granulator.

Dry rolling granulator structure

1.The working part of the machine head: it is transmitted from the drive wheel to the drive roller shaft through the pin coupling. The synchronous operation of the pair of rollers is guaranteed by a pair of open gears. There are specific bearings on both sides of the active and passive shafts, which are composed of bearing frames and installed. on the rack.

2.Rack part: All the working bodies of the machine are all installed and fixed on the rack. The frame of the machine is made of medium carbon steel plate and channel steel welded, and through strict quality control and specific process requirements, to achieve the purpose of this machine, there are hoisting holes in the middle of the four corners of the frame to facilitate loading and unloading transportation.

3.Transmission connection part: The motor drives the pulley, the V-belt and the reducer to drive the machine head to work. In addition, the sprocket and the chain form the transmission chain and transmit it to the crushing and separation working part. The middle transmission reducer and the working part of the machine head are meshed with nylon pin couplings to transmit and drive.

4.Crushing and separation working part: The material flows into the crushing chamber on the lower side after being squeezed by the rollers, and the pellets and the returned material can be separated by the rotation of the double-shaft mace.

Features of dry rolling granulator

1.It is suitable for a wide range of raw materials, and the particle strength can be adjusted according to different materials to control the strength of the finished product by adjusting the pressure of the roller;

2.Compact structure, convenient maintenance, simple operation, short process flow, low energy consumption, high efficiency and low failure rate.

3.The material is forced to be compressed by mechanical pressure, without any additives, the dry powder is directly granulated, and the purity is guaranteed;

4.Cyclic operation to achieve continuous production and high output of finished products;

5.The main transmission parts are made of high-quality alloy materials. The production of stainless steel, titanium, chromium and other surface alloys greatly improves the wear resistance, corrosion resistance, high temperature resistance and pressure resistance, so that the machine has a long service life;

6.It can control environmental pollution, reduce powder waste and packaging costs, and improve product transportation capacity;

7.The dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process;

8.The feeding and feeding device adopts frequency conversion and stepless adjustment control, with a high degree of automation, which can realize multi-machine control by one person, and has the characteristics of low labor intensity and long-term continuous operation;

9.The particle strength is high, and the increase in bulk specific gravity is more significant than other granulation methods, especially suitable for occasions where the bulk specific gravity of the product is increased.
