High Purity Alumina Ceramic Tiles | Wear Resistant Tiles | CUMI

CUMI is a subsidiary of Carborundum Universal Limited, India (CUMI) – one of the companies comprising the multi-billion dollar Murugappa Group. CUMI (Australia) services the Australasian region with a range of wear-resistant alumina ceramic products which include standard tiles, grinding media, pre-engineered liners and complete fabricated and lined process equipment. Ceramic Grinding media, as the name suggests, is used for particle size reduction by facilitating interaction between the media and the material in a closed space. CUMITUFF-90 (90% alumina) products are used for wear resistant applications. CUMITUFF alumina grinding media has a high hardness which ensures prolonged resistance to chipping and cracking. CUMI manufactures high alumina ceramic tiles as well as pipe sections of various diameters for installation at site and more specifically for lining of fabricated pipes, bends and fittings for pneumatic conveying applications specially for conveying of pulverized coal in thermal power plants.CUMI offers ceramic wear protection solutions for coal-based thermal power stations. Our expertise is in manufacturing and supplying pre-engineered wear resistant tiles and ready to fit pre-fabricated lined equipment.

To provide to the varying needs of our customers we ensure the exact specifications and highest quality standards for our ceramic powder. This is made possible by the state of the art ceramic material preparation plant in our facility.

The process starts by checking the alumina and other additives for correct chemical composition and subsequently storing them in different silos connecting to a continuous ball mill. All the tank, silo and ball mill input-output are controlled by SKADA to eliminate the manual errors in the process.

The alumina and additives are sent to a continuous ball mill as per the required formulation and milling operation is performed to get uniformly fine material. The material is then sent to agitator tanks for mixing the binders into the ceramic powder uniformly. After the agitator there is a quality check for the viscosity and particle size characterization. From the agitators this material in the form of a slurry goes to spray dryer.

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This rapid drying ensures that the produced powder is uniformly sized and is of free flowing nature to give compaction during molding. After the powder is cooled in a cooling chamber it is sieved in a shifter mesh to separate all the different sizes present in the powder.

Before sending the ceramic powder for molding our quality and R&D team ensures that the powder will give the desired shrinkage after firing by performing a slug characterization.

Dry pressing is a manufacturing process used for compaction of powders. The powder is sent into feeder box directly from CMP section with no contamination. The amount of powder is CNC controlled & hence accurate. Mould depth is ensured using cams and CNC program for perfect shape and size. These are controlled using hydraulic systems.

Subsequently, the pressure is applied by the top ram which is in relative movement to the feeder box and depth of mould. Facilities up to 250 tonnes capacity are available for pressing at our plant. Next process is ejection of the tile which is controlled by cams, sensors or CNC program and in accordance with the position of ram and feeder box. Ejection of tile is achieved by the robotic arm. Tiles up to 100mm thickness and 220mm length can be moulded with the facility. Tiles are fired only after required quality tests are conducted.
