The vertical preheater is a vertical preheating device that preheat calcined material, its developed on the basis of import and absorb advance technology from abroad and combine with dolomite and limestone calcination features, with characteristics such as rational structure, high rate of heat exchange, high level of automatic. It main used to preheat raw material with poor thermal stability, such as limestone, dolomite and so on. The vertical preheater is used with rotary kiln, make the high temperature air from kiln tail fully utilize, play a role in saving energy and reducing consumption, itâ??s a energy saving and environment - friendly product.
Our products advantages:
1. Push head and main parts of body is made of heat resistance steel, so it can work in 1000~1100high temperature, and have long operation life.
2.Refractory bricks liner with good design and sealing, to insure the material is preheated equally and reach to preheating temperature.
3. Recycle the heat energy in waste air that discharge from kiln tail effective, increase utilization ratio of fuel, at the same time, itâ??s benefit to dedust;
4. The vertical preheater is used in calcination system, the length of rotary kiln will be shorten, to reduce the heat loss on the surface of rotary kiln and floor space;
5.With good combined revenues, the capacity will be increased 30%, thermal efficiency will be increased 40% after use vertical preheater.

Calcined Bauxite: Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application. We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices. Applications of Calcined Bauxite: Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%. Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement. Minimum Order Quantity : 1 Containers
Magnesia Bricks Description Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application. Magnesia Bricks Features: It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature. Magnesia Bricks Application Basic open-hearth furnace for steelmaking Electric furnace bottom and wall Permanent lining of oxygen converter Non-ferrous metal metallurgy furnace Hyperthermia tunnel kiln Lining of rotary cement kiln Heating furnace bottom and wall Regenerative chamber of glass furnace Magnesia Bricks Properties High Refractoriness Good alkaline slag erosion resistance High apparent initial softening temperature Good thermal conductivity High thermal expansion Magnesia Bricks Manufacturing Process Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.
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.

Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
