Weigh hoppers can be used for weighing aggregates as a separate unit or in combination with a moving weighing belt.
A weigh hopper is suspended from load cells and can be installed above the mixer, a skip hoist or a belt conveyor that transports aggregates to the mixer.
The hoist bucket itself can also function as a weigh hopper. The hoist bucket moves into a weighing unit where it rests on two load cells making it possible to use the hoist bucket as a weighing unit or for weight checks.
This is a very compact unit equipped with adjustable parallel hinges between the fixed and movable parts. The hinges make it possible to continuously adjust the angle of the weighing unit between 60° and 75°. The weighing unit can be used where it is not possible to install a weighing belt with high sides. In such locations, the weighing unit combined with a movable weighing belt can weigh out aggregates.
The weighing unit can be used in plants that use batching by volume. Here, the weighing unit can be used for weight checks of each charge. Combined with a Mixo control system, the unit can also be used to calibrate the volumetric batching units.
