Do you know the importance of debugging of sawdust pellet machine?

The Wood Pellet Machine mainly uses tree branches, sawdust and other agricultural and forestry wastes as raw materials, and processes it into pellet fuel, which is used in various industries, and the function of the wood pellet machine has also been improved. There is more room for development.

The debugging of the wood pellet machine is very important.

First of all, understand the process flow of the pellet machine production line and the function of each specific equipment in the process flow.

Before commissioning, check the operation of specific equipment one by one to understand the grinding particle size of the pulverizer that matches the die hole of the granulator used.

The particle size of the raw material should be fine, but not too fine, preferably coarse, medium or fine. The ideal particle size distribution is suggested as:

The particle size of a and above 3.35mm is less than or equal to 1%;

The particle size of b and above 2.0 mm is less than or equal to 5%;

The particle size of c and above 1.0 mm is about 20% ≥ gt;

d The particle diameter of 0.5mm and above is about 30%,

e 0.25mm and below not less than 20%,

F 0.25mm and above is about 24%;

Before commissioning, clean the warehouse to remove debris such as stones and welding slag left in the installation process.

Before putting into operation, check whether the steam piping system used has good decompression and drainage functions to ensure the required dry saturation during the granulation process. Before starting the granulator, there is always 0.058-0.4mpa of steam behind the pressure reducing valve, and the pressure roller and ring die should be adjusted.

Under normal circumstances, the pressure roller will not rotate like when the ring die is rotated (that is, the distance between the pressure roller and the ring die is preferably 0.1-0.4mm).

It is not allowed to make the distance between the ring die and the pressure roller too small to cause direct friction, which will not only accelerate the friction between the ring die and the pressure roller, but also reduce the unit output in the production process.

When starting the granulator, the feeding should be stopped when the instantaneous material amount reaches the maximum value, and a small amount of material and a small amount of steam should be added at the same time to make the feeding amount reach the ideal value (that is, the motor current value is 85-95% of the rated current value of normal production). ).

The wood pellet machine is suitable for a wide range of raw materials. The pellet fuel produced has the characteristics of clean combustion, effective environmental protection and energy saving. With the further development of environmental protection, it not only realizes turning waste into treasure, but also improves the value of crops, and also promotes The ecological environment drives economic development.
