We offer the best product range of Ash Slurry Disposal System.

Paddle Mixer

Mixer conveyor is known in the industry by various names such as Paddle mixer, Ash Mixer, Pug Mill, Unloader etc. 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 Conveyor System

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. The periphery of leading side of the helix is provided with hard face welding for handling abrasive material.

Ash Slurry Disposal System

Flow quantity of Slurry and pressure required are the basic parameters required for designing the system. However, these two parameters in turn depend on many other conditions like rate of ash to be disposed, pipeline distance, pipeline profile, density of slurry, viscosity of slurry etc. Moreover ash is highly abrasive and pipeline wear also needs to be considered. A critical aspect of system is selection of slurry velocity in the pipeline which should be low to minimize abrasion but high enough to avoid settling of Ash in the pipeline.Slurry with low or medium concentration (usually 45% to 50% by weight) can be pumped using centrifugal slurry pumps. The viscosity of slurry does not have much effect for such conditions while calculating pressure requirement, but as the slurry concentration increases the viscosity effect has a dominant effect for calculating pressure requirement. Generally ash slurry pumping beyond 65% in not feasible, as high concentration slurry requires extremely high pressure which increases exponentially as per the concentration. Such high pressures can be developed using piston diaphragm pumps. These pumps can develop very high pressures but are very costly and have a very high maintenance cost. The high pressures result in higher power consumption though the water requirement is lower in this system.

Ash Handling Systems

Fly Ash is the major constituent of the ash generated from Pulverized and Fluidized bed Coalfired boilers. The Fly ash gets collected at various points, with most of it in ESP hoppers. One of the methods for handling Fly Ash is Wet system in which the ash is mixed with water to form slurry which is pumped to slurry pit.

Slide Gate Valve

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. DEMECH Slide gate valves are simple and compact in design, robust in structure, excellent in technology and are easy to install. Slide gate valves are designed to shut off product flow from outlets of storage bins, silos, conveyors, and other discharge points handling dry bulk materials.

Drag Chain Conveyor

DEMECH have been one of the pioneers in India to manufacture and supply En-Masse & Drag Chain Conveyors. 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
