Selecting the Proper Lime Kiln Technology. Lime is a key industrial mineral used as a chemical additive by many industries. The industrial facilities that utilize Lime in various forms are metal ore processing, metallurgy, steel, paper, pharmaceuticals, sulfur removal, and water treatment.

Rotary cement kilns are fired with a wide array of fuels including pulverised coal, pulverised (or shredded) noncoal solid fuels such as wastes, fuel oil, natural gas, .

Pulverized coal burner is the key equipment of calcination system in metallurgical, chemical, cement, quicklime rotary kiln, its performance and operation relate to product quality, capacity, energy consumption, environment and so on. Our company design pulverized coal burner is according to different kiln type, different feature of pulverized coal and different technical conditions, with typical .

the rotary kiln to reducing conditions, which increases the tendency for deposit formations in the rotary kiln material inlet end, kiln riser duct and lower cyclone stages. Clinker quality may also be affected by minor compounds from the fuel ashes or from unburned carbon leaving the rotary kiln with the clinker.

On average – tonnes of coal are consumed in the kiln per kilogram of clinker cement production. As such coal storage during cement manufacturing is an important component to consider in hazard analysis. Among the various causes of coal fires, spontaneous combustion during storage results in a large number of losses.
