A method of analyzing degrees of granule grinding includes steps of: passing granules between a coherent-light emitter and a light receiver directly receiving a coherent light emitted from the coherent-light emitter; measuring the time of each of the granules intercepting the coherent light, and the frequency of such interception; and, analyzing the measured granules by arithmeticallyprocessing the intercepted time, frequencies and predetermined coefficients. An apparatus for carrying out such method includes a passage for granules to pass through, and to intercept, the coherent light between the coherent-light emitter and the light receiver, a counter for counting from outputs of the light receiver the interception time of the granules passing at the passage, a memory for storing outputs of the counter, frequencies of each of such output values and predetermined coefficients, and arithmetic operator for conducting calculations based on the information stored in the memory. This apparatus for analyzing degrees of granule grinding can be advantageously incorporated in a granule grinder for its roll-space adjustment.
