Lime in Pulp and Paper Mills. Lime is used in several applications within pulp mills. . This lime is mixed with water, forming slaked lime. The sodium carbonate returning from the pulping process is than added to the mixture to form caustic soda, whereby the process is started all over again.
Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill slakers are generally used where: the capacity required is too large for other types of slakers.
Slaking is the reaction that occurs when solid lime, or calcium oxide is added to water, creating calcium hydroxide. What is causticizing? Causticizing is a reaction in which sodium carbonate in green liquor reacts with calcium hydroxide from the slaker to form sodium hydroxide and calcium carbonate.
The superior paste-type slaking technology consistently produces a higher strength and more reactive lime slurry resulting in more efficient and more economical use of the quicklime. Systems are factory assembled and tested for quick and easy installation, and include options for lime feed and grit removal.
A horizontal ball mill can be used as in a lime slaking circuit just as well as a vertimill. Some operations apply the raw quicklime directly to the ore on the belt moving toward further crushing or grinding. In this application, it is necessary only to have a suitable lime storage tank with a live bin bottom and a means for metering the lime from the tank to the ore.

Many high-consumption lime industries use Sodimate quicklime slakers as opposed to using powdered hydrated lime or ready-mixed lime slurry. Our slakers are able to absorb the exothermic reaction of calcium oxide and water, and efficiently separate lime grit from the highly concentrated calcium hydroxide resulting from the slaking operation.
