Which feeder for which application

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.

HETHON in a nutshell

HETHON was founded in 1973 and was specialized in pumps and total solutions for the graphic industry. In 1988 Hethon developed a first dosing device for dry products: the HETHON Feeder.

Think of the accurate dosing of plain flour, bakery flour, salt, sugar, but also pigments, spices, milk powders, lactose or plastic granules, wood flour, scrap, toner: in other words, too many to mention.

Dosing machines already existed for all of these products, but Hethon specialised in substances that are difficult to dose and can bridge or degradade. mainly intended for the processing of difficult to dose powders that can 'bridge' or segregate. In 2000 the production was partly accommodated in Slovakia.

Production

Brenda Kesteloo, the founder's daughter, took over the company in 2008 in Hengelo. In 2013, the company moved to a much larger building in Doetinchem this time.

In 2017 Brenda Kesteloo, the founders doughter, took over the company in Slowakia. Production and stock moved again and became centered mainly in the Netherlands, she found it desirable that HETHON’s own products were produced in-house.

Developing

Eventually, a number of new machines were developed for filling the HETHON Feeders, including: Big-Bag emptying, sack emptying or Bag-dump stations, screw conveyors, and vacuum conveyors: the VacuFeed. Even today, custom made powder handling components are still being developed and produced. We are still working on more perfect dosing components and related items as weging scales, control boxes, level sensors etc.

Representatives

Beside own their own brand "HETHON" (dry material handling equipment), HETHON also represents several pump, rotating joint and valve companies. All high quality products like our own products.

Simply said, HETHON has two elements: "wet" and "dry". Pumps, rotating couplings, and related items are of high quality. In 2014 HETHON became a distributor of YTS-pump engineering. She also a distribute ARO, YTS, Fürgut,Nakakin, Haag + Zeissler Rototech and GRI
