Industrial grade calcium hydroxide production
The power consumption of using the HCQ digestion system to produce industrial grade calcium hydroxide is outstanding among many equipment and similar production line equipment. The electricity consumption for the production of calcium hydroxide is 18-23 kWh/t. (depending on the difference in the available calcium oxide content)
Selection of raw materials for calcium hydroxide production
Metallurgical lime is not recommended for further processing. The production of deep-processed lime such as calcium hydroxide and calcium ash powder must meet the deep-processing standards.
Before starting the machine, check the normal maintenance of the motor pulley belt, reducer lubricating oil, etc.
Feeding, the feeding at startup starts from the minimum amount of 30-50% of the designed capacity. After adding water, start adding water 1-2 minutes after adding the material, and the ratio of starting to add water is from low to high. Increase the water from 20% to around 48%. Select the appropriate water ratio according to the lime condition.
The maximum feeding amount is the appropriate amount to fill the digestion screw shaft with the dissolved ash.
The digester no-load stream is similar to the load stream and there is little change. When the load current is greater than 20% to 30% of the no-load current, the entire system should be inspected.
Be sure to follow the principle of stopping water first and then stopping the material, and gradually reduce the amount of water added half an hour before the shutdown, and reduce the output to less than half of the normal production in the digester after the shutdown.
