DOSING TECHNOLOGY FOR GRANULATE
Our loss-in-weight feeders are suitable for pellets, fibres, grinded materials, micro-pellets or polymer-powders. Our volumetric feeders MONO, LOGO, SOLO und GOLO can be converted into our gravimetric feeders MODUS, ECONO, RATIO and GOLIA by linking the feeder to a platform scale. The output of the feeder is determined by the choice of the gear, discharge pipe and screw.

DOSING TECHNOLOGY FOR FLUIDS
Our loss-in-weight feeders are suitable for fluids, for example oils, softener, silanes, water, waxes, silicones and glycerines. The feeders are designed for outputs of 0,1 - 1000kg/h, viscosity of 0 - 100000mPas, pressure up to 200bar and heat up to 160°C. The feeders are available as mobile units. Depending of the use, a diaphragm, gear, hose or piston pump is used.
WEIGHING TECHNOLOGY
By linking a platform scale, volumetric gravimetric dosing devices are created. All of our platform scales have an identical height. We offer two different measurement techniques, the PESA string technique and the strain gauge technique (DMS). Depending on your capacity requirements, the feeder will be linked to a SCHOLZ BASIC 300, SCHOLZ BASIC 400, SCHOLZ BASIC 600 or SCHOLZ BASIC 800.
PESA-STRING-TECHNOLOGY
The tension of a vibrating string is influenced by the load weight on the platform scale, which changes the vibration frequency. The weight is determined from the change in the oscillation frequency. The technology is used for gravimetric feeders with SCHOLZ BASIC300, SCHOLZ BASIC400 and SCHOLZ BASIC600.
DMS-TECHNOLOGY
The measuring principle is based on the change in electrical resistance when suitable materials are stretched and compressed. The load on the platform scale thus causes a voltage change by which the weight is determined. The technology is used for batch applications as well as gravimetric applications with SCHOLZ BASIC700.
GRAVIMETRIC EQUIPMENT
We offer accessories for gravimetric dosing devices. The folding and step bellows as well as the pipe caps, filter bags and hose clamps are particularly easy to maintain as they can be easily replaced.
