Demech Gcf-1026 1000 Mm Gravimetric Feeders

We are dedicatedly engaged in exporting, supplying and manufacturing of Demech GCF-1026 1000 Mm Gravimetric Feeders in Bhosari, Maharashtra, India. The three standard models manufactured by demech have the following basic specifications. However, using the same design platform, Demech can develop coal feeder with variations as per the requirement of customers.

Features:
Gravimetric Coal Feeder manufactured by Demech is essentially a belt conveyor which measures the amount of coal, in terms of weight, being conveyed / fed to the pulveriser.
The feed rate is computed from load cell signal and belt speed signal collected from the load cells strategically mounted below the belt and the Hollow shaft sensor mounted on the tail pulley of the belt conveyor in the weigh controller.
The control and instrumentation features are achieved by combination of weigh controller, VFD and PLC-HMI housed in local & remote control panel.
The most prominent feature of Demech feeders is the load cell mounting arrangement which is bottom supported, pivot mounted cantilever frame. This arrangement makes it possible to use only one load cell for accurate load measurement unlike the side suspended two load cell arrangement.
This arrangement provides rigidity, easy alignment, protection against vibration & impact and has no effect of lateral forces due to the belt motion.
This also makes it possible to have low tension on the belt thereby increasing the life of the belt. Due to low belt tension, the feeder does not have the weigh down roller and the tail end roller also act as tensioning roller with external tensioning arrangement.
The belt has a unique continuous side wall with no cuts or opening which virtually eliminates coal spillage and does not allow any seepage of water to underside of belt.
The skirt liners cover the side walls from inside with their gap so adjusted to avoid any lodging of bigger coal particles between them.
The crowned drive pulley helps in centering the belt with addition of bottom V-guide further protects against belt slippage.
The motors are direct shaft mounted eliminating alignment activity.
