After selective quarrying the rock is melted at a temperature of around 1500 degree C and cast into molds or spun into cylinders. The castings so produced are then subjected to heat treatment cycles in special kilns to produce re-crystallized basalt. The product thus produced inherits inertness of parent materials. Its microcrystalline, non-porous texture being denser and more homogenous than raw basalt, it acquires exceptionally high abrasion resistance.

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.

Slow moving chains in these conveyors influence the material to move gently through a closed duct in a horizontal or even in steeply inclined profiles. These can handle virtually any type of bulk material in an environmentally safe way due to its dust-tight and spill proof, totally enclosed construction. These conveyors are heavy duty and of rugged construction.

CHROMAX wear plate by DEMECH is a composite plate, manufactured by a unique process in which a uniform layer of highly wear resistant carbides is deposited on a carbon steel base. Very hard carbides are suspended in a tough wear resistant matrix. It is the concentration & uniform distribution of carbide structure that gives CHROMAX Wear Plate its unique wear resistant & life prolonging characteristics.

CHROMCAST is an excellent combination of abrasion resistance capability of Chromium- Molybdenum white iron with ductility, toughness and weldability of mild steel. The white cast iron conforming to ASTM A 532 Class II, is a hard material having very high hardness and wear resistance.

DEMECH has been supplying Submerged Scraper Conveyors (SSC) since early 1990 and has recently entered into technical collaboration with Hitachi Power Europe, GmbH, Duisburg, Germany to manufacture SSC of large size which are required for the bigger boilers.

DEMECH Mixer Conveyors find applications in many industries. This equipment is the perfect solution for pollution control as it effectively blends dust - recovered from ESP, Mechanical collectors, bag houses, Silos etc.- with various liquids, thus allowing transport but effectively controlling the particulate matter escaping into the air.

Screw conveyors are used to convey the material continuously with the help of a rotating helical screw blade (known as flights) by shear and tumbling effect inside a U shaped trough or a round tube. They are generally used for handling fines of coal, crushed material, powders, cement, chemicals etc.

DEMECH supplies Bucket Elevators for vertically transporting various free-flowing bulk materials from dust to material having particles up to 30 mm.

DEMECH provides a complete range of Rotary Airlocks suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to precision feeders for dilute phase and continuous dense phase pneumatic conveying systems.

Double Cone / Flap valves are used for controlled feeding as well as achieving air lock sealing. These valves consist of two independent Cone / Flap valves mounted one upon other with their opening and closing alternated and synchronized to ensure that only one valve opens at a time.

DEMECH Slide Gate Valves are designed to provide a quick acting isolation valve unit that can be installed into a bulk handling flow path to stop material flow.

Diverter Gate Valve is used for selecting one out of two outlet ports. The flow through these valves is essentially a gravity flow and the position of the diverter flap decides which of the two outlet ports will be active.

Demech has entered into technical collaboration with Hitachi Power Europe GmbH (HPE), Duisburg, Germany; to manufacture Gravimetric Coal Feeders. This gives Demech the unique advantage to supply Gravimetric Coal Feeders using the proven and reliable designs of Hitachi Power Europe GmbH.

Volumetric Coal Feeder is a special variant of Chain Conveyors. Backed by many years of experience in manufacturing of Chain conveyors, DEMECH has also executed number of orders for Volumetric Coal Feeders for prestigious clients.

DEMECH provides variety of systems to handle Bottom Ash or Bed Ash generated by the solid fuel fired boilers. The system has to be selected based on many factors like type of boiler, size of boiler, amount of Bottom ash generated, method of final handling etc. Factors like availability of other resources like water, land etc. also need to be considered while selecting the system. DEMECH can supply following systems

DEMECH Hyjector is designed for the best efficiency and long life. The Nozzle &Ventury throat is designed to suit the application. The slurry can be pumped to a discharge pressure of 30 meters. The main advantage of this equipment is it can operate when the suction is inadequate and chances of air being sucked is high where a normal pump can never operate.

DEMECH Feeder Ejector can be directly mounted below hopper without any feed elbow. DEMECH feeder ejectors are highly efficient and can create ash slurry of concentration up to 35% to 40% resulting in low water consumption. Assembly is made in four major parts. Discharging angle 450 and 700 are available to suit layout. The water pressure required is about 4 kg/cm². They are available with two capacity ratings and sizes i.e. 30 TPH & 60 TPH and 6"×4"×8" & 8"×4"×8" respectively.

The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible. In such conditions ash is required to be dumped in ash pond / ash pits which are usually far away from the plant area. The most efficient method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes.
