The moistening machine is the main equipment in the pelletizing process. It processes materials with a water content of 8%-13%, so that the materials are fully mixed and refined, and the surface area of the material particles is increased. The use of a moistening mill can shorten the pellet production process, save equipment energy consumption, and improve the quality of pellets and metal recovery rate, improve labor conditions and environmental protection conditions, etc., so it is quickly promoted in the pellet process. The working principle is that when the surrounding large gear drives the cylinder to rotate, the material is impacted by the steel ball of the grinding medium, and the grinding between the ball and the ball and the cylinder liner fully exposes the fresh surface. It is fully mixed, and finally discharged from the mill through the discharge hole to enter the next process. This machine can effectively reduce the added amount of bentonite and increase the green strength.

Based on the ball mill, the wet mill has three main features: forced feeding, peripheral discharge, and rubber liner.
