            Vertical Lime Kiln

            DETAILS

            Process Description
            The manufacturing of Quick Lime consists of following steps: - 
            1 Pre-treatment
            2 Pre-heating
            3 Calcination
            4 Heat recovery
            5 Cooling & Storage
            In Pre treatment section, lime stone is screened to remove undersize & washed in rotary screen by using water to remove impurities like dust, dirt, mud etc. These impurities are separated out in a settler and clear water is reused for washing.
            The washed Lime Kiln is then charged to the vertical lime kiln from top through the winch arrangement. In this zone, lime stone is preheated up to a certain temperature by using heat from hot exhaust gases (CO2) of lime kiln.
            Lime stone is then entered in to a calcining / reaction zone of lime kiln. Here, the temperature is controlled near about 1100-1200°C by burning the fuel (Natural gas/fuel oil) & combustion air mixture in a controlled ratio. The total air requirement is fulfilled by two stage air feeding system, primary air for fuel burning in burner and secondary air for recirculation inside chamber.
            To gain a better efficiency of lime kiln, the re-circulation air is preheated up to a certain temperature in a heat recovery system. Here secondary air is heated up by the heat of hot air, obtained during cooling of burnt/quick lime from lime kiln bottom. The cooled quick lime obtained from lime kiln is then transferred to storage area.

             Major Plant Equipment and Machinery

            Vertical shaft lime kiln and charging device

             

            Vibrating Screen

            It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry, smelting and so on.

            Vibrating Screen Features and Benefits:

             

            It features long flowing line, many screening specifications, strong violent vibration force, high screening efficiency, small vibrating noises, firm and durable construction, convenient maintenance and safe operation

             

            Vibrating Screen Operating Principle

            It adjusts the amplitude by tube-shaped violent vibration screen of eccentricshaft and eccentric blocks. The body moves like a circle, in order to make the materials screened.
