METHOD OF OBTAINING LIME RU2677724C1 PatentGuru

Limestone is moved in the burning zone at a speed of 400–800 mm/min. In the process of moving vibrating conveyor give oscillatory motion with an amplitude of 2–4 mm and a vibration frequency of 1,000–1,500 1/min. Heating and burning of limestone is carried out by a combined coolant: a catalytic heat generator and an infrared radiation source.

Extraction of natural stone MeGran Marble Limestone

When processing the surface of the stone by shearing, the texture is obtained: a rock type, which is characterized by a natural stone break, forming knolls and depressions on the surface without marks of the machining tool of the barber; Thus, they process granite, syenite, diorite, labradorite, quartzite, gabbro, sandstone, basalt, limestone ...

Lime kiln Wikipedia

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 C (1544 F), but is generally considered to occur at 900 C(1655 F) (at which temperature the partial pressure of CO 2 is 1 ...

PROCESS DESCRIPTION

In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000). The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)). The components of a contactor include a contact tank, limestone bed, inlet line, outlet line, overflow line, access lid (for …
