Description
PREPARING MILK OF LIME
The DSL milk of lime production plants represent the ideal engineering solution for the industrial preparation of fluid mixtures and suspensions based on water and hydrated lime also known as slaked lime or calcium hydroxide Ca(OH)2 or calcium carbonate CaCo3, with operating concentrations ranging from 3% to 15%. Milk of lime is a fundamental chemical compound utilized in multiple strategic sectors, among which building and construction, agriculture, the chemical industry, the environmental sector, and the food industry stand out. The most common and widespread industrial uses include, in particular, the neutralization of pollutants contained in liquid effluents during wastewater treatment processes, the improvement and correction of acidic soils, the preparation of agricultural mixtures, desalination processes, purification within the production cycle of specific foods, and the cooling of diamond tools used in rock cutting.
LIME STORAGE AND DISSOLUTION
The plant consists of one or more silos for storing hydrated lime and a DLS dissolver with an internal agitator, into which water and lime are fed. According to the estimated consumption and the characteristics of the installation site either traditional vertical monolithic, telescopic, modular panel silos or EUROSILO horizontal silos with low environmental impact can be chosen. The dissolver is equipped with a paddle or marine propeller agitator, which ensures homogeneous dution of lime in water and prevents lump formation. It is supplied with inspection hatches, overflow outlet, dust vent with filtering system, and lifting hooks. The entire plant operates fully autonomously according to the parameters established and levels set in the management software, strictly adhering to the weight percentages and chemical concentrations required by the downstream industrial process.
VOLUMETRIC DOSING AND ELECTRONIC WEIGHING
The plant can operate either in batch mode or continuously, and the system can be managed by timed volumetric control using level sensors, or by gravimetric electronic weighing with load cells operating by weight reduction.The electronic weighing system ensures high dosing accuracy, uniform mixing, and consistent results, detecting and correcting potential issues such as bridging inside the silos that may prevent lime discharge. The system also allows for monitoring and recording the total consumption of lime and water, providing complete process control.
