The patented Stirred Vertical Ball Mill Lime Slaker is a continuous mill that processes quicklime into hydrated lime. Hydrated lime is used extensively in agriculture, construction, and other industries. UP CLS Attritors are unique in that they eliminate grit separation and disposal problems by slaking the lime as well as grinding the inert grit.

Ball mill slakers are made to order in quicklime slaking capacities up to 50,000 kg /hr. As with conventional detention slakers, horizontal ball mills operate at water to lime ratios (in the slaking compartment) between 3.5:1 to 6.0:1. The water to lime ratio in the mill is adjusted automatically to maintain a constant slaking Get Price

Both quicklime and hydrated lime can be converted into slurry through specialized equipment systems. Quicklime is reacted with water in a device called a "Slaker" through a process called "slaking".Slaking is an exothermic process meaning that heat is produced as the quicklime reacts with water and this heat must be managed by carefully controlling …

Granulation fitness improves significantly with use of pre-heated water. BI and GI of sinter feed mix increases by 9.7% and 5.3% with use of pre-heated water at 90 °C. Reduced surface tension of water and slaking rate of lime are considered to be the most important factors governing the granulation fitness. 2.

Slaking can be achieved in a variety of slaking reactors including ball mill slakers, detention slakers, and stirred tank slakers (Oates, 1998). 5. ... For a continuous production process, the slaking temperature is primarily controlled by the lime-to-water feed ratio of the slaker (typically at mass ratio of 1:8 to 1:4) and the reactivity of ...

The ratio of hydroxide to CaO is 74 ÷ 56 = 1.32. This means that 1 Kg of CaO and 0.32 Kg of water will produce 1.32 Kg of Ca(OH)2, this is the minimum water required for chemical reaction, so calcium hydroxide contains 75.7% CaO and 24.3% H2O.

and rapid changes in lime concentration when required. Compact Size The 2:1 slaking ratio and short retention time allows for a smaller slaking compartment without bulky insulation or any need for a water jacket. The A-758 lime slaker takes about 20% less floor space than other designs. KEY BENEFITS Saves water, heat and power

Void Space Ratio. Lime should fill the entire void space between the sand. Excess lime pushes the particles apart and weakens the mortar. To little lime will leave voids and weaken the mortar. A test to determine the void space in sand is fill a clear 100 mL beaker with dry sand. Measure 100 mL of high proof grain alcohol.

Factors Affecting Lime Slaking The lime slaking process and product quality depend on three primary factors: quicklime properties, water properties, and water to lime ratio. In most applications, water to lime ratio is the single most important factor in lime slaking; as this ratio is decreased, product quality increases.

A ball mill slaker is a subset of the class of slakers commonly called a detention (or 'retention') slaker. Detention slakers are slakers that operate on either a batch or continuous basis with a water to lime ratio such that the contents of the machine remain a liquid slurry (<28% concentration) rather than forming a paste.
