Description

В ходе процесса измер ют потребл емые мощности РЬ ... Р„ и производительности размольных агрегатов Qb Qn, определ ют суммарную фактическую производительность 2 Qt и сравнивают с пп данной 2Сз- 2 Qj AQ. Периодически вычисл ют переменные величины относительных удельных энергозатрат за равные промежутки времени В случае необходимости уменьшени суммарной производительности при 21 Qt 2Q/3 нагрузку на каждый агрегат уменьшают пропорционально величине его относительных удельных энергозатрат. в случае необходимости увеличени суммарной производительности при 2 Qi S Q(3 нагрузку на каждый агрегат увеличивают пропорционально обратной величине его относительных удельных энергозатратIn the course of the process, the consumed power Pb ... Pn and the productivity of the grinding units Qb Qn are measured, the total actual capacity 2 Qt is determined and compared with the parameters of this 2Сз-2 Qj AQ. Periodically calculate the variables of the relative specific energy consumption for equal periods of time. If it is necessary to reduce the total performance at 21 Qt 2Q / 3, the load on each unit is reduced in proportion to the value of its relative specific energy consumption. if necessary, increase the total performance at 2 Qi S Q (3 load on each unit increases in proportion to the reciprocal of its relative specific energy consumption

Claims

1. USSR author's certificate number 324071, cl. B 02 C 25/00, 1969. In case of exceeding the value of the relative specific energy consumption of one of the maximum permissible units, this unit is turned off, and the performance difference is distributed in this way. The use of the proposed method of controlling a group of parallel-working grinding units will improve the uniformity of the working parts of the units, reduce the cost of electricity and promptly turn off the grinding units with worn out working parts. Claims I. A method of controlling a group of grinding machines operating in parallel, consisting in stabilizing the total capacity by distributing the load on each working unit in proportion to the sum of specified performance, characterized in that, in order to ensure evenness of the units and reduce energy costs, they measure productivity and the power consumption of each unit, periodically calculate the variable values of the relative specific energy consumption of the aggregate s and if necessary to reduce total load reduces productivity per unit in proportion to its value relative specific energy, and if necessary increase the total productivity increase load per unit in proportion to the reciprocal of its relative specific energy.

2. A method according to claim 1, characterized in that, in order to promptly replace worn out working bodies in the grinding unit, the variable value of the relative specific energy consumption of the units is compared with the maximum allowable, and in case of exceeding, the unit is turned off.
