When the three rollers are at the same height, the adjacent rollers are attached together, and at the moment, the gap between the rollers is minimum and close to zero. When the gap between the rollers is increased, the adjusting screw 19 is turned to lower the height of the first roller 5, thereby increasing the roller gap. In fact, for slurries with different viscosities, the adjustment amount of the roller gap is relatively small, generally speaking, the adjustment amount is not more than 0.05mm, if the diameters of the three rollers are all 50cm, the roller gap is from zero to 0.05, the height of the first roller 5 only needs to be reduced by 3.54mm, and if the pitch of the adjusting screw 19 is 1.25, only 2.8 turns of the adjusting screw need to be rotated. Meanwhile, the heights of the two ends of the adjusted first roller 5 are kept equal, and a level ruler can be adopted for ensuring. Since the belt itself has elasticity, a small change in the belt tightening force caused by a small rotation of the adjusting screw 19 will not or hardly affect the life of the belt.

The utility model has the advantages of be suitable for the grinding of the thick liquids of multiple viscosity, when the formula changes, grinds the thick liquids of another kind of viscosity is glued to the structure, can not appear that the thick liquids grind insufficient and can not appear the energy consumption too big.
