Calcined Kaolin

REFRACTORY KAOLIN

AIMR is the largest exporter of Fireclay in Egypt and considered one of the top refractory kaolin suppliers to the European market.

AIMR’s 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 Al₂O₃ in 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 optimized chamotte for refractories industry which have a high control of chemical properties; providing our partners a rich Al2O3 bulk 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.

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).
