Overview

DEMECH manufactures a wide range of high alumina ceramic liners such as tiles, special shapes and pipe sections which have high alumina content and wear protection properties. These liners are bonded on to steel surfaces and are extremely effective for prevention of wear and tear due to high particle velocity, impingement, abrasion and impact. They are extensively used for lining of equipment prone to severe wear in core sector industries such as cement, steel, power.

Demech manufactures ceramic tiles in the form of weldable and pastable 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 pulverised coal in thermal power plants

Alumina powder after ball milling and spray drying are pressed and sintered at high temperature. This sintered product consists of dense alumina with hardness of approximately 9 Mohs and can withstand temperature up to 10000C.
