The control system of mix material feeding is intended for batching of coal and calcareous stone in the gas (limekiln) oven.

After receipt of the command "Start" by the block №1 (coal) the batching cycle of the mix material begins.

The block №1 (coal) produces powering-up command of the relay RP1 and loads coal into the weight hopper according to the task, then the signal from the relay RP1 is taken off. After batching of the first component the block №1 (coal) shapes the unloading signal, thus the relay RP2 is powered up. The contacts of the relay RP2 shape the signal "Start" for the block №2 (stone).

Having received the signal "Start" the block №2 (stone) checks presence of the signal from the limit switch of the skip position, and if the skip is in the batching position, powers up the relay RP3, thereby simultaneously stone batching in the skip (contacts KЗ.2) and coal unloading in the skip (contacts KЗ.1) begins, the contacts КЗ.3 imitate operation of the limit switch of the unloading mechanism of the component №1 (coal). After termination of batching of charge mixtures in the skip hoist the signal from the relay RP3 is taken off. The contacts KЗ.3 shape the signal of the termination of unloading of the component №1 (coal), thus the block №1 accumulates and stores the common and shift total by the first component (coal).

The block №2 (stone) shapes the signal "Unloading", powers up the relay RP4 and waits for the termination of the unloading process of the skip hoist, controlling the signal of the limit switch of the skip position. At returning of the skip hoist after unloading in the home position the block №2 (stone) accumulates and stores the common and shift total of the batched mix material (coal + stone). For receiving of weight of the batched stone it is necessary from the instrument readings №2 subtract the instrument readings №1.

If in the block №1 (coal) the capacity is set, the block waits for the termination of pause between the repeating of the batching cycle, and begins the new batching cycle.
