Feeding & dosing
Powder dosing
Powder dosing combines weighing with screw or vibratory feed. Closed runs and PLC recipes keep rates repeatable – including stainless steel for food, pharma and chemicals.

Operating principle
A scale drives a screw or vibrating trough to set-point. The run stays closed so dust and moisture do not spoil the result. PLC recipes switch product, target and start ramps. Stainless versions meet hygiene needs ahead of bag, pail or big-bag packing.
Where this machine is used
Food, pharma, chemicals, construction chemicals and fertiliser – as dosing ahead of bag, pail or big-bag packing.

Frequently asked sizing questions
How does industrial powder dosing work?
Powder is discharged from a storage vessel in a controlled manner and fed to a process stage. Depending on the material, this can use a screw or vibrating trough. Weighing and control equipment compare actual and target values and adjust the feed to the selected operating mode.
Screw feeder or vibratory feeder?
Selection depends on bulk density, particle shape, flowability, bridging, segregation tendency, product sensitivity, cleaning and the downstream process. Both principles therefore need assessment using actual product and operating data.
Which process data do we need?
Please provide material, bulk density, particle size, moisture, flow behaviour, dose per unit of time or batch, required repeatability, operating time and temperature. The request should also cover the storage vessel, downstream equipment, materials of construction, cleaning, dust control and automation.
When is additional testing required?
Poor-flowing, sticky, very dusty, hygroscopic or segregation-prone products may require discharge aids, different geometry or trials with original material. A specific dosing accuracy can only be assessed after the product, dosing range, measurement principle and operating conditions have been defined.
