An automatic control method, system, equipment, and medium for a series refiner unit are disclosed, relating to the field of automatic control. The method includes the following steps: acquiring pulp demand information; configuring the operating mode of the series refiner unit based on the pulp demand information; determining the operating parameters of the pulping process based on the refiner unit's operating mode and acquiring time-of-use electricity price information, the operating parameters including at least the energy consumption per unit time of the pulper and the energy consumption per unit time of the refiner unit; establishing an operating energy consumption model for the pulping process based on the operating parameters and time-of-use electricity price information; optimizing the operating energy consumption model to minimize energy consumption; and planning the start-up and shutdown states of the series refiner unit and pulper in subsequent operating time units of the pulping process based on the optimization results. By adopting the technical solution provided in this application, the equipment involved in the pulping process can be better controlled, thereby utilizing the time-of-use electricity pricing system to reduce the total energy cost of the pulping process.

A measurement system for monitoring a gap adjustment mechanism of a processing device which has oppositely positioned processing elements with a gap between them. The measurement system has a first measuring device to measure information describing a position of that processing element which is moved by at least one actuating unit of the gap adjustment mechanism for adjusting the size of the gap, and at least one second measuring device to measure information describing a position of the at least one actuating unit. The measurement system has a data processing device configurable to determine the condition of the gap adjustment mechanism based on the information describing the position of the processing element and the information describing the position of the at least one actuating unit. Additionally, a method for monitoring a condition of a gap adjustment mechanism of a processing device.

The invention relates to a method for operating a refiner (1), wherein grinding plates (2) are rotated relative to one another by means of a drive in order to comminute organic fibrous material located between the grinding plates (2) and / or to separate fibres, in order to form a product consisting of fibre material and / or separated fibres. In order to achieve a particularly efficient method, the invention provides that the quality, in particular the homogeneity, of the product should be detected and the relative rotational speed of the grinding plates (2) should be changed in dependence on the quality. The invention also relates to a refiner (1) for the fibre formation of organic fibrous material in order to obtain a product consisting of fibre material and / or separated fibres, wherein the refiner (1) has grinding plates (2) which can be rotated relative to one another by means of a drive.

A solution for controlling cellulose processing comprises performing (200) optically first measurements of the cellulose during the processing, performing (202) second measurements of the cellulose by directing (204) optical radiation to the cellulose, the radiation comprising at least one beam that is polarized and at least one separate beam is non-polarized, measuring (206) attenuations and parameters of polarization of the radiation interacted with the cellulose and determining size of particles in the cellulose based on at least one comparison of the parameters of polarization and the attenuations. The processing is controlled (208) based on the first measurements until a given threshold of the first measurements has been reached and thereafter controlling the processing based on the second measurements.
