It is necessary to carry out a running-in process when the feed pellet machine is replaced with a new one or if it is not used for a long time. The main component of the running-in is the running-in mold. The grinding disc belongs to the wearing parts of the pellet machine. It is very easy to wear under the work of high strength and high pressure. How long is the service life of the grinding disc under normal conditions? How can the grinding disc damage be minimized during the operation?
Generally, a flat die plate made of ordinary alloy steel can usually be used for 600-800 hours. If a manufacturer says that it is longer than this time, it must be a bluff. According to the international standard for alloy steel grinding, the flat die plate must be replaced until the particle density does not meet the requirements.
Mold work of feed pellet machine
(1) The die plate rotates and wipes the flat die granulator of the pressure roller structure. The material of the jaw crusher is easy to erect, resulting in uneven feeding and affecting the output.
(2) The die plate is stationary, and the pressure roller rotates. Although it does not arch, it generates centrifugal force, and the material that enters the granulation chamber is smashed to the periphery, so that the stencil hole is upward and the hole is evenly distributed. , resulting in material accumulation, uneven thickness.
The general key components (pressing rolls, stencils) are made of high-quality alloy steel, specially heat-treated manufacturing process, and have a long service life. Diversified formwork, round bars, squares, granules, as long as you can change the mold to do it, adapt to different materials compression molding, to achieve the best results.
