    Dynamic Weighing - JesBuffer

    JesBuffer

    Jesma has developed a dosing feeder system for regulation and dosing of an even flow of very light materials (density from 20 kg/m3) like straw, paper, different types of carved fibres, alternative fuels, mineral wool fibres etc.

    The weighing system consists of a dosing feeder with a pre-bin and a weigh feedertype JesBelt A.The weigh feeder receives the material from the pre-bin (buffer), which by means of an adjustable drum secures that the material flow to the weigh feeder is executed with a fixed layer thickness.The level in the buffer is held constant via speed regulation of the feeding device.The buffer is able to handle a variation of a volume up to 1 m3 and at the same time maintaining a constant layer thickness on the weigh feeder.

  • Loss in Weight
    System

    Dynamic Weighing - JesBelt A

    Loss in Weight System

    The Jesma loss-in-weight feeder is a fully electronic weighing system, which is specially designed for continuous dosing of additives with a high dynamic accuracy incl. the critical stage of re-filling the weighing bin.

    The functional principle for a LIW system is through repeated static weighing of the product bin to determine and regulate the mass flow.The product bin is slowly emptied, and the relation between the loss in weight and the speed of the discharge system gives the amount signal, which controls the dosing speed to the required value.

    To achieve highest possible dynamic accuracy, the discharge system is mounted with a 2-channel incremental encoder with high signal rate which continuously monitors the speed of the discharge and signals the actual speed to the Jesma weigh controller.Through careful considerations regarding product characteristics, all Jesma loss in weight feeders are designed for highest possible dynamic accuracy, market leading operational reliability and user friendliness.

    Dynamic Weighing - JesLoader

    JesLoader

    The new unique development in truck loading scales.

    Jesma JesLoader is designed for loading a pre-set amount of bulk material into a truck from multiple silos. The JesLoader is mounted on rails so it can be moved from one silo to another, loading the required amount of material from each. The JesLoader eliminates the need for mounting a scale below each silo or the need for repeated trips to a bridge scale after the filling from each silo.

      The functionality of the Jesloader:
    • After the truck has been positioned correctly, the driver enters the order no. into the control system. This can be a part of the overall control system or an IT8000E receipt handling solution from Jesma. Note: the overall control is not part of Jesma’s delivery.
    • The JesLoader will position itself correctly below the pre-programmed silo by navigating via an incremental encoder (Tacho counter)
    • When the Jesloader is positioned under the silo, the correct amount of product is released into the scale as ordered through the receipt handing system.
    • After completed filling, the JesLoader is guided into the correct position above the truck inlet by means of a remote-control unit. The product will be released into the truck by accept from the operator.
