Brief introduction about rotary kiln 

Rotary kiln, also called cement rotary kiln and lime rotary kiln, belongs to the class of building material equipment. 

Rotary kiln can be divided into cement rotary kiln, calcinating rotary kiln and circumgyrate kiln according to different processing materials. 

Rotary kiln equipment is mainly used for calcining cement clinker, with dry process production and wet process production two kinds. 

Calcinating rotary kiln is mainly used to roast lean iron ore magnetization, chromium and nickel iron for metallurgical industry, to calcining alumina bauxite ore for refractory plant, to calcine clinker and aluminum hydroxide for aluminum manufacturer, to roast chromium ore mineral powder for chemical plants, etc. 

Circumgyrate kiln is used to roast active lime and calcined dolomite for roasting plant and ferroalloy plant. 

The calcination technology of rotary kiln has low energy consumption, stable performance and high yield; after going through processes of dehydration, decarburization, whitening, etc., its product can be used in papermaking industry, coating industry, etc.   

Brief introduction to lime rotary kiln 

Lime kiln, also known as lime rotary kiln or lime pit, belongs to rotary kiln; it is main equipment to calcine active lime, composed of cylinder body, support device, bearing device with hydraulic gear wheel, transmission device, lubrication device and sealing device, with simple structure, reliable operation and convenient automatic control. 

Performance characteristics of horizontal lime kiln 

The horizontal kiln has advanced structure; it adopts reliable combined-type 

scales seal on both ends of the machine, so that the air leakage coefficient is less than 10%; kiln lining uses composite refractory, reducing radiation heat loss; in addition, horizontal lime kiln makes full use of waste heat, which can preheat secondary air into the kiln to 700 ℃ or above, saving energy greatly.
 

Working principle of limestone rotary kiln 

Pulverized coal produces heat in the furnace, then the heat is conducted to materials through gas or radiation; at the same time, kiln body keeps turning according to the design of slope and speed, and raw materials also periodically roll forward in the stove so that they can be sent to discharging end from feeding end. 

Hongxing company is always committed to the improvement of limestone rotary kiln. We will try our best to make progress in the performance of lime rotary kiln!
