Submerged Scrapper Conveyor (Demech 0.03 M/s 400 Bhn)

With immense experience of this domain, we are instrumental in exporting, supplying and manufacturing of Submerged Scrapper Conveyor (Demech 0.03 m/s 400 BHN) in Bhosari, Maharashtra, India.
SSC is a double strand chain conveyor for handling high temperature materials, which drops in the water which the conveyor is filled with. The chain strands are submerged in water and moves at very low linear speed of about 0.03 m/s and scraps out the material from the water.
There can be two variants in SSC depending on top or bottom chain action as the material conveying member. In the first one where the top chain conveys the material, has the return inactive chain outside the water filled chamber. The other variant where the bottom chain does the conveying activity has both the chain paths submerged in water.
The surface over which the chain scraps off the material is lined with hard material like Cast Basalt tiles or plates of 400 BHN hardness. The chains are either forged round link chains or drop forged machined chains.
A major part of SSC is the cooling water system. The water is maintained at a constant level in the conveyor chamber which is also used to air lock the furnace internals against atmospheric pressure by dipping the inlet in this water. The quantity of flow of cooling water to the conveyor is calculated based on the temperatures and flow rate of the material. The excess water is allowed to overflow from the conveyor through simple trap separator or a parallel plate separator. The overflowing water can be re-used after cooling it or drained off as per customer's requirement.

Application :
Handling Bottom Ash of coal fired boilers or any solid fuel fired boiler. The Economizer Ash and Coal Mill rejects if dumped in the SSC used for Bottom Ash will also be then removed.
To handle hot Kiln Dust of Direct Reduced Iron (DRI) plants.

Features:
DEMECH designs and supplies tailor made custom designed to suit customer's requirement of material handling rates and layouts.
Cast basalt lining to suit requirement is possible as it is an in-house item.
Long term collaboration agreement with Hitachi Power Europe GmbH ensures knowledge of best design engineering and new developments taking place to give better systems.
