china coal gangue rotary kiln manufacturers, suppliers, factory - best price coal gangue rotary kiln made in china - z-land heavy industry

china coal gangue rotary kiln manufacturers, suppliers, factory - best price coal gangue rotary kiln made in china - z-land heavy industry

Scope of application:mainly used in metallurgy, chemical industry, building materials and other fields for calcining materials. Materials: coal gangue, coal kaolin, activated lime, cement, bauxite, hematite,etc.

Coal gangue, also known as coal series kaolin, is an associated mineral of coal and a unique precious resource in China. Although it is available abroad, it has a thin ore bed and no mining value.Coal-based calcined kaolin is praised by the paper and coatings market for its high whiteness and high hiding power, and occupies an important position in the market.At the same time, with the shrinkage of domestic washed soil resources, coal-based calcined soil is increasingly favored by customers.

Coal gangue rotary kiln is a special equipment for calcining coal gangue. The coal gangue calcined by the rotary kiln has its high purity and high calcination whiteness. It is widely used in paper making and coating, especially coated paper and coating The added value of the product is relatively high.Soft kaolin and sandy kaolin are mainly used in paper coating and ceramic industries.

The coal gangue rotary kiln operates under heavy load and alternating speed at high temperature, and the level of its accessory equipment maintenance and thermal system control is related to the efficiency of the rotary kiln operation.The main points of the maintenance of the transmission device are the lubrication of the equipment, the running state, the dynamic detection and the meshing accuracy of the large and small gears; the installation accuracy of the supporting device determines whether the rotary kiln can operate reliably. The layout of the supporting wheel, the upward and downward pressure and time of the hydraulic stop wheel, the force of the supporting wheel, the gap between the wheel belt and the backing plate.The quality of the sealing device directly affects the thermal engineering system and operating cost of the rotary kiln.Strengthening the daily maintenance data sorting and analysis of kaolin rotary kiln is conducive to equipment management.

In the process of coal gangue rotary kiln, raw meal powder is fed into the kiln tube body from the lower discharge tube at the upper end of the kiln tail tube body. Due to the inclination and slow rotation of the kiln tube body, the material is rolled in the circumferential direction In the compound movement of moving from high temperature to low end along the axial direction, the raw meal is decomposed and fired in the kiln through firing and other processes. After firing the cement clinker, it is discharged from the bottom end of the kiln barrel and enters the cooling machine.Fuel is injected from the kiln head and burned in the kiln. The heat generated heats the raw meal to make the raw meal calcined into clinker. The hot air formed during the exchange of materials with the kiln feed end enters the kiln system. From the chimney into the atmosphere.

The calcination process system and process calcinator, which are determined by the classification of coal series clay, soft and hard soil can realize the fast decomposition, slow redox and drying use of heat source. The composite calcination kiln developed by our company is a kind of new advanced process equipment, which is according to kaolin clay calcination process.

The composite kaolin calcination kiln is mainly composed of three parts. Drying part: dynamic pre-decomposition kiln and rotary decomposition-reduction kiln, use the exhaust of decomposition-reduction kiln as the heat source of dynamic pre-decomposition kiln and drying equipment to realize energy utilization, and it can calcinate ordinary soil, double-90 kaolin clay and cable-level kaolin clay.

Adopt internal combustion rotary kiln, the hot air generated by taking gas and oil as heat source enters into the kiln, and calcine the kaolin clay after drying and pre-decomposition in weir kiln, and then the exhaust is discharged through the dryer of pre-decomposition.

AIMRs Refractory Grade Fireclay (Calcined Kaolin) is considered one of the lowest cost refractory clays in the middle east which makes it the favorite grade for Alumina refractories manufacturers in Europe.

The Alumina content Al2O3in our Refractory Kaolin reaches levels up to 41% after it passes through rotary kiln (calcination process) which makes it the perfect binder chamotte for refractories industry production with the lowest Alumina unit cost in the whole region.

AIMR supplies the optimizedchamottefor refractories industry which have a high control of chemical properties; providing our partners a rich Al2O3bulk kaolin or sieved ready-to-use China Clay which refractories manufacturers can rely on

AIMR committed and dedicated technicians, mining and production engineers are engaged in each step of the extracting and developing of our raw Egyptian kaolin from its early beginnings, till it reaches our customers warehouses whether in its bulk status, packed in jumbo bags, calcined or sieved on a pre-requested mesh (micron) size, in a time frame and quality standards which AIMR always insure to fulfill its customers satisfaction.

Our raw kaolin for the refractories applications comes directly from our mines located in the top region for refractory clays in Aswan, Egypt. Our production of kaolin open-pit mines exceeds 70,000 tons. The raw kaolin is then transported to our facility in Alexandria for the calcination process.

Using extremely high temperatures reaching 1400 C in 92m long rotary kiln to remove some unwanted elements and to alter the properties of minerals, the calcination of kaolin generally increases hardness and alters the electrical properties of the material. The process also leaves the Kaolin anhydrous (without water).

Depending on your countrys regulations and restrictions, we can come up with a solution and packaging option to deliver your clay safely and efficiently with the most convenient way to your refractories production process.
