Best Hongxing Rock Crushing Equipments
Research on lime slaking has been done on a restricted basis in current years. Most of this investigation has been done under auspices of the National Lime Association. The data presented in this paper builds upon the research performed by other people and the author’s years of hands-on knowledge in lime slaking.
Lime Slaking Process
Because rock is actually a naturally occurring mineral its chemical composition and physical characteristics differ not simply from location to region but within veins of rock in the very same area. This variation in raw material outcomes in variation of quality of the finish item, which is calcium hydroxide.
The use of lime in its a variety of types has been steadily on the rise with no end in website. At this time lime will be the most significant chemical utilized all through the globe for pollution control. It really is, as a result, imperative that information of handling and processing lime be well understood by all people that use this chemical.
LIME MANUFACTURING AND LIME SLAKING PROCESS
Rock or calcium carbonate (CaCO3) exists as a natural stone all through the globe. Rock in its all-natural form is very slow reacting; thus, it has a limited use. The most important use of pulverized rock is in agriculture in a finely ground and dry form or in flue gas desulphurization in slurry form. The use of lime in carbonate form is beyond the scope of this paper. We’ll concentrate on lime as calcium oxide and calcium hydroxide.
In most pollution control applications lime is utilised as calcium hydroxide. To manufacture calcium hydroxide the rock calcium carbonate must be converted to calcium oxide and also the calcium oxide then converted to calcium hydroxide.
THE equipment Applied FOR THE SLAKING PROCESS
It is not the intent of this paper to evaluate the slaking equipment described below. The intent is usually to show the varieties of equipment obtainable for slaking procedure. You will find essentially four varieties of lime slakers obtainable on the market. They may be:
A. Slurry Detention Slakers
B. Paste Slakers
C. ball mill Slakers
D. Batch Slakers
A slaker must mix the appropriate quantity of speedy lime (CaO) and water, hydrate the quicklime, and separate the impurities and grit from resultant calcium hydroxide slurry.
