How to achieve high pelleting output?

If you want to have a large pelletizing output, 5 pellet machine standard operations cannot be ignored.

Since the development of the pellet machine industry, more and more companies have joined this industry, the market is getting bigger and bigger, and the industry has begun to roll inward.

To gain a foothold in this industry, reducing machine wear and power consumption, reducing production costs, ensuring pelletizing quality and increasing pelletizing output are the most concerned issues for manufacturers. In addition to the limitations of the machine's own conditions, what standard operations can make pelletizing production efficiency the best?

Standard operation and reasonable use of pellet machines are important factors that directly affect pelletizing quality and output. The adjustment and parameter changes of pellet machines mainly include the following points:

Feeding speed

The feeding speed directly affects the load level of the pellet machine, thereby affecting the output and quality of the pellet machine. In order to maximize the performance of the pellet machine, the feeding speed should be adjusted according to the rated current of the main motor, and it must not be overloaded.

Die aperture and compression ratio

On the premise of selecting high-quality ring molds, the appropriate die aperture, hole type, opening rate and compression ratio should be selected according to product variety, raw material moisture and output. A small compression ratio of the ring die can increase the output of the pellet machine, reduce energy loss, and reduce the wear of the ring die roller; but if it is too small, the pellets will not be formed, loose, and of different sizes.

A large compression ratio will result in good pellet forming, smooth surface, and low powdering rate; but if it is too large, it will result in low output, excessive energy consumption, blackening and carbonization of the pellets, and even machine blockage.

We should choose the most suitable ring die material and compression ratio according to the different raw materials we produce. Under the premise of ensuring the strength of the ring die, the opening rate of the ring die should be increased as much as possible.

During use, it is necessary to avoid excessive sand or iron impurities in the raw materials, or the ring die is forced into the bearing ball and other metal hard objects that fall into the pelletizing chamber. In addition, if the gap between the die rollers is too small, it will also cause mold explosion or cracking.

Die roller gap

Combined with production experience, the most suitable gap for processing general raw materials is 0.1-0.3mm, and some raw materials are 0.3mm-0.5mm. If the gap between the die rollers is too large, it will affect the extrusion of the raw materials, and if it is too small, it will aggravate the wear of the die rollers.

In actual production, since the gap is difficult to measure, the "intermittent contact method" can be used to adjust it, that is, adjust the roller when there is no raw material on the inner surface of the ring die, so that it is in a state of seemingly rotating but not rotating when the ring die rotates.

Select wear-resistant accessories

During the production process of the pellet machine, the wear of the accessories will directly affect the performance and life of the equipment.

Selecting high-quality wear-resistant RICHI mold rollers and other accessories can resist the high pressure and friction of the pellet raw materials, thereby reducing wear and extending the service life of the ring die roller, which plays a vital role in extending the life of the machine, improving production efficiency and reducing maintenance costs.

Cutter

Adjust the position of the cutter so that the pellet length meets the production requirements. The gap between the cutter and the die is generally not less than 3mm, and the cutter should be kept sharp. When the cutter is blunt, the pellets are not cut off but interrupted or knocked off, the pellets are bent and cracked, and usually one end of the pellets has more serious cracks, and the powdering rate increases.
