Chemical Machine

Operation :
It operates on the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to get the required size reduction. Material fed in the hopper goes down to the processing chamber where it moves to the periphery and passes through the screen radially and tangentially. Finally the processed material gets collected in the container kept below the processing chamber. Output and quality of the final product depends on three main factors :

• Shape of beaters (knife/impact edges)
• Speed
• Screen

Features:

• Reliable performance
• Rugged design
• Optimum work ability

Lime manufacturing and lime slaking process:

• Limestone or calcium carbonate (CaCO3) exists as a natural stone throughout the world. Limestone in its natural form is very slow reacting therefore, it has a limited use
• The most significant use of pulverized limestone 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 will concentrate on lime as calcium oxide and calcium hydroxide
• In most pollution control applications lime is used as calcium hydroxide
• To manufacture calcium hydroxide the limestone calcium carbonate must be converted to calcium oxide and the calcium oxide then converted to calcium hydroxide
