    • The connection simultaneously evaluating the load development of the kiln is designed for the regulation of the burning process in the cement rotary kiln. The connection consists of the evaluation block of the limit values, whose signal input is connected via an analogue-to-digital converter to the reader of the drive energy input. The output of the signals of the limit values is connected to the module of a graphical representation and the control input is connected to the output of the block of a control logic, to which the time storing unit of the rotation and the time storing unit of the extreme are also connected via their control inputs, from which the time storing unit of the rotation has its input of its time signal connected to the master clock generator and its output is connected to the first input to the arithmetic unit, while the time storing unit of the extreme has its input of the time signal connected to the master clock generator via the phase gate, and its output is connected to the second input of the arithmetic unit, whose control output is connected to the block of the control logic and the output is connected via the phase storage to the module of the graphical representation, whose control input is connected to the block of the control logic. The input of the block of the control logic is connected to the sensor of the rotation of the rotary kiln, while the phase gate is equipped with the blocking input, which is connected to the output of the signal of the extreme value of the block of the evaluation of limit values.
