There are two types of load cell weigh hoppers – a single hopper or a double dump hopper.
Single weigh hopper – Fitted with either a variable pitch screw or a chain and flight conveyor.
The load cells are located onto the hopper body and steelwork supporting frame, a defined amount of material may be fed into the hopper, then discharged as a batch via the discharger when required, in to the system.
Double dump weigh hopper – Comprises of two hoppers one above the other. The top hopper accepts the material and registers its weight and is fitted with a ‘bomb door’ to allow the material to fall into the under hopper. Once the material has left the top hopper the bomb doors close and the material may be fed in to the top hopper, while the original batch of material in the bottom hopper is being discharged in to the system.
Weighing and Control
The weighing system uses load cells that are linked via transducers and amplifier to the PLC in the control panel. This allows the PLC to control several different pre-determined weights accurately, to form the batch required for the up-line processing system.
The size of the hoppers are dependent on the batch size and the physical site space available.
Levelling screws may be used at the top of the top hopper. This enables the materials with a poor angle of repose to be spread evenly across the hopper.
Drum dryers are normally used within process systems and depending on the materials, can be
manufactured from carbon steels or a combination of carbon and stainless steel. The drying medium is dry steam and uses a recirculation system that efficiently and cost effectively removes moisture. The dryers may be used in most industries, including biomass. For materials that are very high in moisture content, a belt or screw press may be used prior to the drum dryer to help make the running more cost effective.
