The principle of feeding volumetrically starts with keeping the screw full. The effectiveness and accuracy are strongly dependent on a constant and homogeneous filling of the dosing screw.
This method provides consistent, repeatable metering with linear control with materials that are considered “good” powders. A good powder has a consistent bulk density, and manageable characteristics.
Volumetric feeding falls short of capacity requirements when a material has a varying bulk density. Material that can vary widely in bulk density within a batch will struggle to meet dosing requirements with a Volumetric feeder.
Choosing the right feeder for your application is important to the cost and quality of the output of your facility. The basics are outlined here, speaking with a bulk material handling expert form our company to design the optimal system for your application is important to achieving quantifiable savings in the long-run.
The HETHON Feeder 30 was developed specifically for the dosing of small quantities. Particularly for laboratory applications and in pilot plants simulating production processes, this series has excellently proved its added value.
• The dosing of powders in small containers of lab- equipment at
• The dosing of poly-electrolytes in water purification plans
• Adding defoamers or other additives in the extrusion process in the plastic
• Adding flavoring, odeur and coloring substances in the food industry.
The HETHON Feeder 30 is equipped with a powerful three-phase motor for driving the screw and the massaging paddles. The frame is made of 304 (and optionally 316) Inox.
The flexible hopper is easily detachable, without the use of tools. Also the extension hopper can be removed quickly by loosening a single bolt. As such, the device can be cleaned quickly and easily.
The HETHON Feeder 30 has a hopper content of approximately 1 litre, which can be increased by use of a 7 litre extension hopper. The HETHON Feeder 30 is available with or without control. It can easily be applied to your existing installation, for example in a carrousel with formula or as a stand-alone.

The HETHON Feeders 40 up to and including 70 are available with 1 of 2 motors. The optional second propulsion makes it possible to have the paddles and screw moving independently. This way the paddles keep the material in motion whilst the screw only rotates slowly.
The flexible hopper is easily detachable. Also a possible extension hopper can be removed quickly. Therefore the device is very easy to clean.
The HETHON Feeders 40, 50, 60 and 70 are easy to expand with the accessories and complementary products which can be found here. Using an extension hopper the capacity can be increased by up to 250 litres.

Hethon supplies control boxes for volumetric and gravimetric dosing. Our standard control boxes for volumetric dosing are equipped with a touchscreen to operate your Feeder. Standard software allows us to operate our single or duo motored machines on a start/stop, time basis or pause/pulse operation. The control box is fitted in a stainless steel Rittal case.
Both the cabinet for single and duo motor Feeders have the same dimensions. This conscious choice was made so that a customer who later wants to upgrade his single-engine Feeder to a twin-engine does not receive unnecessary extra costs in the form of a completely new control box. New components can be placed in the current control box because this has already been taken into account in the construction and size selection.
All our control boxes are standard prepared for:
A customer does not have to incur unnecessary costs if they want to upgrade the system (afterwards). Simply purchase a level sensor later, place it and connect it in the cabinet without building an expensive control box, adjusting software.
Custom made is possible:
Models are available in ATEX!
