A screw conveyor is a material handling equipment to convey the material for shorter distance by shear and tumbling effect. Constructional feature comprises of staionary housing of U or circular trough with a rotating screw shaft with a Helix shaped flight mounted on it. Flight normally will have hard facing on the leading side on the periphery of helix. Shaft is generally supported at end on bearing to take up radial and thrust load.
Drag Chain conveyor is a material handling equipment to convey the material for medium amd shorter distance by dragging the material with the help of chain link assembly. The constructional feature comprises of conveyor in three segments. They are drive end casing segment, Tension end casing segment and intermediate casing segment.
Wet Scrapper also know as submerged scrapper conveyor largely used in sponge iron plant and power plant to collect the dust at elevated temperature. Construction is more or less identical to chain conveyor filled with water, however differs in tail end and drive end. Both the ends are at inclined position normally restricted to 30 degree inclination. Wet scrapper will always have double strand construction with low linear speed as theses are usually used for highly abrasive material at elevated temperature ( upto 900 Degree Centigrade ). In sponge iron plants of capacity 200 TPD and below the dust will be passed through dust cooling tower and then dust settling chamber. Wet Scrapper are installed below this DCT and DSC. Where as in power plant below the boiler to collect the unburnt ash, the wet scrapper/SCC are installed.
It is a type of mixer which also conveys the material - combining both functions of mixing and conveying in a single machine.Homogeneous mixtures of multiple granular/ powdery materials & liquids are possible. Replaceable paddles or wear resistant paddles can be provided for special applications. Various capacity ranges are available in M.S. and S.S. construction.
DEMECH is the leading manufacturers of coal feeders. Coal feeders are used in coal fired Boiler for
(1) Feeding coal lumps to pulverizing fuel mill and
(2) Crushed Coal of size -6mm from storage bunker to Boiler furnace.
Each bunker has a coal feeder to feed & remove the mills and discharges the raw coal to the mills, where it is pulverized before being blown into the furnaces. The feeder discharge rate modulates in accordance with the demand signal from the boiler control system.
Bucket elevator is a material handling equipment required to convey the material in vertical direction. Basically are employed convey the fine powder to lump size particle. Normally size varies from 500 micron to 30 mm. Conveying buckets are mounted either on belt or chain as per material character. Conveyor speed is selected based on the type of discharge. Drive platform is provided at the top near drive end casing. For maintenance purpose an inspection window is provided at the boot section of bucket elevator.
This is a combination of chain conveyor and Elevator. The shape of conveyor resembles a swan neck and can lift materials up to 90 degree inclination. Requires minimum supporting structure. U flights are used for En-masse conveying of material. Material moves in any direction – horizontal, vertical, inclined at any angle and minimizes transfer points. It is designed to suit one or more feed discharge points. Operation is dustless and explosion hazards are minimized.
CAST BASALT is produced by melting basalt rock and then shaped into tiles or cylinders. The special heat treatment process forms a fine crystalline structure that gives CAST BASALT its outstanding qualities to resist sliding abrasion. CAST BASALT is used to enhance the life of various process equipments in power plants, steel and cement plants.
DEMECH brand high Alumina ceramic is a product from high purity, fine grain aluminum oxide (Al2O3). Sintered dense Aluminium possesses a high consistency, hardness , temperature & Corrosion resistance. It is harder than all other except diamond.
These are used to withstand heavy erosion and corrosion in power plants and pneumatic handling systems. The necessary forming of shape is done in its green phase. The products are then sintered in a kiln at extremely high temperature. The resulting alumina ceramic products are dense, durable and wear resistant; outlasting other Wear Rresistant Products. many a times. Because of its superior mechanical and thermal characteristics; Alumina ceramic material widely used all over the industry..
As the mainstay of our business, DEMECH is providing to customers with all possible solutions of Wear Resistance Material in a wide variety.
Chromcast is designed to protect your equipment from high impact and high abrasion & to cut equipment downtime by quickly replacing worn parts.
CHROMAX Plate is manufactured by a unique process developed indigenously by which a heavy layer of highly wear resistant carbide is deposited on to a mild steel base. Very hard carbides are suspended in a tough wear resistant matrix. It is the concentration of the carbide structure that gives CHROMAX Plate its unique wear characteristics.
This is continuous Ash Extraction system for Bottom Ash. Submerged Scrapper Chain Conveyors are specifically designed for handling high temperature bottom ash which is quenched and dewatered continuously.
Demech feeder ejectors are high efficient and create high concentration upto 40% with low water consumption. Air inlet valve regulates constant vacuum inside body.
Demech wetting head directly can be mounted below hopper without any feed elbow. Body is made of a combination of multiple nozzles.
Demech Wetting heads are high efficient and create high concentration upto 55 to 60% with low water consumption. Air inlet valve regulates constant vacuum inside body.
Replaceable multi-jet nozzles are fixed on nozzle plate which facilitates operator easy maintenance. Discharge bend is also optimal to promote flow and reduce the water getting in trenches.
The valves are installed to remove air from pipe line and avoid water hammering. The valves are used for allowing air inside the pipe for draining or after the pumps shut down due to vacuum.
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 convey systems.
# Note: Customized sizes can be supplied in fabricated construction as per customer requirement
Demech Divertor valves are designed to direct product flow outlets of storage bins, silo conveyors, gravity flow chutes and other discharge points handling powders , granules, grains and other bulk solids. These valves are available deflector or divertor types, with three-positional control on diverter if required to split the flow.
In Any Process Industry, where corrosive and abrasive material are handles, the life of the plant shortens considerably due to wear. This wear may be due to the high abrasuve and corrosive nature of the materials, Direction of flow, friction, Climatic conditions etc. This gradually reduces the life of the equipment leading to
The interruptions of downtime occur due to abrasion, wear or corrosion can now be overcome by using cast basalt lining. Demech indigenously manufactures Cast Basalt liners in the form of Cylinders and TIles.
Ash extraction valve is used in Vacuum conveying system which is state between hopper and conveying line. Ash extraction valve is metal seated. Seat and disc is made from special alloy steel which gives better life than SS. During the operation gate operated by Pneumatic actuator and gate is away from the path of material, this feature helps to increase life of the valve & gives better performance than the slide plate of valve.
Demech SDV is used for material cut off below hopper for dry powder / granular material.
Air inflatable seat, sealing the valve in closed position. Thus during valve operation there is no direct friction between seat and dome which ensures longer life.
