FIELD: process engineering.
SUBSTANCE: invention relates to device and method of levelling grinding surfaces of two opposite grinding disks. Proposed method and device are used for grinding material containing lignocellulose in the clearance between grinding surfaces. Note that method consists in measuring in, at least, three measurement points in grinding zone and grinding disk with the help of, at least, three pickups arranged at different points. Measurement in said points comprises measuring vibration at each measurement point in operation using said pickups. Proposed method comprises also the comparison of results obtained at said different points.
EFFECT: higher efficiency of levelling.
