Rotary Kiln, rotary calciner, rotary furnace, rotary Lime Kiln,, Handan metallurgical engineering & Research Co. Ltd (MER) currently is the TOP professional company majoring in design, equipment fabrication, installation, production, training, and commissioning in China. So far, the company has undertaken around 100sets of rotary kiln of Active Lime (dolomite calcinations).,, MER energy saving revolving kiln of Active Lime (dolomite calcinations) production line is the most uniform calcinations technology and equipment for Active Lime (dolomite calcinations), adopting advanced vertical preheater, rotary kiln and vertical cooler technology. It can reduce energy consumption, raise production capacity, reduce costs, and achieve good results in emission reduction and energy saving. The raw material particle size is 15~45mm, the product activity is 420ml. The fuel can be gas and solid, or mixing. The products specifications include 150t/d, 200t/d, 300t/d, 400t/d, 500t/d, 600t/d, 700t/d, 800t/d, 900t/d, 1000t/d and 1200t/d.,, MER vertical pre-heater has high heat exchange efficiency. After the pre-decomposition, the material will be returned to rotary kiln to be further calcination. The system makes full use of the residual heat of flue gas. The Adjustable technology of conveying pipe is firstly originated in China. It enlarges the particle size range of material.,, The refractory lining of MER rotary kiln adopts new-type multiple energy saving brick which is an exclusive technology and developed independently. Contrast with the traditional refractory material, the multiple energy saving brick can reduce the temperature of kiln surface, and prolong service life of rotary kiln. Adopting advanced average cooling air technology, MER vertical cooler achieves high efficiency in heat-exchanger and uniform cooling. After being heat transferred, the secondary air is directly forced into the rotary kiln to be reused., We are the manufacturer of lime kiln, we can provide high quality rotary kiln such as limestone rotary kiln.
Peripheral Burner Vertical lime kiln, shaft kiln, vertical kiln, vertical lime, vertical shaft kiln
MER high efficiency and energy saving gas burned single shaft kiln, its body structure adopts advanced scientific design of ANSYS software stress analysis. The patent structure has a stable strength of masonry structure, compact structure, reasonable stress, reliable operation, less wear and tear. The kiln lifetime is more than 10 years for one-time. The kiln covers small area, flexible arrangement.We are the best Pfr Kiln suppliers in China.
MER Has a strong ability for supplying a complete set of kiln equipment, and owns independent intellectual property rights of new energy-efficient gas burned single shaft series products. The capacity includes: 80 t/d, 100 t/d, 200 t/d, 250 t/d, 300 t/d.
The raw material size is 40~80mm, the product activity is~320ml. The fuel is gas.
We are the manufacturer of lime kiln, we can provide high quality Shaft kiln such as annular shaft kiln, cement kiln, industrial kiln, limestone kiln.
Annular Shaft Kiln originated in the sixty's of last century, Germany, formerly known as Beckenbach Annular furnace charge zone lime Vertical kiln, is a kind of lime vertical kiln, with two shafts, inner shaft and outer shaft. The raw material is calcined between the inner and outer shaft space.We are the best Pfr Kiln suppliers in China.
Annular Shaft Kiln technological process
Annular Shaft Kiln inner structure from top to bottom is pre-heating zone, upper counter-follow calcining zone, lower parallel-follow calcining zone, and cooling / discharge zone. Raw material is screened firstly, then transferred to the top of the kiln by the hoisting hopper, and then feed into the kiln body by the rotary distributor evenly. Preheated raw material moves into the upper calcining zone along the annular furnace chargespace in where the raw material is effective in decarburization. The almost-finished lime in the upper calcining zone moves into the lower calcining zone for effective homogeneous, then moves down to the cooling zone, finally drops into the lime silo under the kiln by lime pusher platform. The finished lime transferred to the storage by the belt conveyer.
