The high concentration of energy-saving grinding machine is the modern paper industry to dispose of chemical pulp, semi-chemical mechanical pulp, mechanical pulp, ideal for cold soak method of high yield pulp and fiberboard material grinding equipment. High concentration grinding a wider scope of application of the slurry, regardless of the species complex, the slurry of the material difference, or the rest of the scrap wood processing and wood shavings, sawdust, Setsuko pulp, cotton stalk, stalk, shrub branches wood, rice and wheat grass, reeds, hemp variety of commodity pulp, waste paper, bagasse, binata, etc., are its higher spin linear velocity and a proper grinding gap separation into a high-quality fiber. High-consistency refining, the fiber cut less significant in silk broom effect, and the flexibility of fiber, which can effectively protect the fiber length of short fibers of the broad-leaved trees and grasses.
