Belt weighfeeders

Typical conveyor belts are designed to carry material and usually do not meet the requirements of precision weighing. By analysing their faults, we have created special constructions of belt feeders, so that the measurement accuracy is the highest in the long-term use.

We care about proper selection of belt, scraper, gravity tension and belt guide system. Depending on the type of material, hopper baskets are selected (also for materials subject to aeration). Support elements are made with the highest precision and remain protected against unfavourable external conditions. The control systems and drives used in the belt feeder can work in a very large operating range (min / max up to 1/20) and depending on the demand they enable dosing in batch mode or continuous mode, but it can also only be used to measure flowing material.

Our offer includes three basic types of belt feeders with capacities from 20kg / h to 1500t / h. For customers from the food industry, we especially recommend the DTU feeder, which due to its high hygiene and minimum dimensions meets the high demands placed on devices in this industry. DTC is an advanced and universal solution, designed especially for heavy materials that have to be fed with high accuracy. For customers with lower requirements and interested in the economic version of the feeder we have prepared a DTL model.

The DTU belt feeder is a unique solution in our offer. Due to its high precision, it finds a particular application in feeding delicate products or in low and medium bulk density. In particular, thanks to the hygienic construction, which allows for an extremely easy cleaning, and the manufacture of fully certified materials and stainless steel is suitable for the food industry. Its uniqueness lies in compact dimensions and very high accuracy. The built-in scale, depending on the control system, allows dosing in batch mode (batch) or continuous mode, it can also only be used to measure flowing material. The feeder can be both in the open and closed version - in a dust-tight housing.

  • measurement error <0.5% (in selected cases <0.25%)

Waga DTL


The DTL belt feeder is an economical solution to the problem of feeding loose materials. The device can be supplied in many variants, with different widths of belt width and wheelbase. The offer also includes weight variants for work in the food industry, made of stainless steel using certified materials. The DTL feederr can be supplied in a dust-free housing. The main purpose is products in the form of powders or granules.

  • rigid construction made of painted carbon steel (on request also made of stainless steel)
  • flow from 0.5 to 50t/h
  • belt width from 300 to 1400mm
  • wheelbase from 1500 to 7500mm
  • maximum measurement error of ± 0.5..1% of the given dose (depending on the type of material)
  • belts made of PVC or polyurethane, also with side skirts
  • drive shafts with a diameter of 190 mm or Ø240 mm, rubberized
  • internal scraper
  • external scraper
  • feeding bulk materials in the range of 10-100% of the nominal flow value
  • various chute constructions adapted to the characteristics of bulk material, also for materials that are easily aerated and flowing
  • Penko or Siemens control system allows you to handle both a single dosing line and create a mixing mode according to the prescribed recipes.

The DTC feeder is the most versatile solution for feeding bulk materials with medium and high bulk density. The device has been designed to work in the most difficult conditions, in particular in heavy industry. High quality workmanship and durable materials allow for long-term and trouble-free operation, while ensuring the required accuracy of dosing. The feeder is made in terms of customer requirements, with different overall dimensions. Various variants of charging baskets allow for proper work on theoretically difficult to feed materials - strong abrasive, aerating, flowing or pounding. An additional mechanism counteracting the belt's deviation will reduce the risk of its damage, and the constant weight guaranteed by the gravity take-up will significantly extend its life and increase the accuracy of the measurement.

  • rigid construction made of painted carbon steel (on request also made of stainless steel)
  • nominal flow from 1 to 1500t/h
  • belt width from 650 to 1400mm
  • wheelbase from 1500 to 7500mm
  • maximum measurement error of ± 0.5% of the given dose
  • the option of installing a legal-for-trade conveyor weighing machine (OIML class 1)
  • belts made of SBR or PVC rubber, also with side skirts
  • additional belt gravity take-up system
  • belt skew counteract system
  • drive shafts with a diameter of Ø190mm or Ø240mm
  • internal and external scraper
  • feeding bulk materials in the range of 10-100% of the nominal value
  • various chute constructions adapted to the characteristics of bulk material, also for materials that are easily aerated and flowing
  • possibility of using hard wearing materials to protect elements particularly exposed to abrasion

Control systems


Flex 2100

Flex 2100 with DBLT software

For belt feeders, we offer the Flex 2100 (or Flex) controller, which is equipped with a touch screen with process visualization, special software created by us in Polish and extensive communication capabilities (RS232 / 422, Ethernet, Profibus, Canbus). The driver enables, among others control of belt slip, reading from sensors - speed and weight, selection of gravimetric and volumetric mode, control of material feeding speed by means of so-called prefeeder (device fixing the layer of material on the scale) and a preview of 3 dosing counters. The software can also be modified to control the remaining elements on the production line.

How does it work

Dozowniki taśmowe - Zasada działania

The belt feeder is a conveyor whose structure has been designed primarily to measure the flow of bulk material. This means that not only does it have a built-in belt scale, but all of its elements are made extremely precisely. For proper operation, the control system needs signals: belt speed and material mass on a precisely defined belt segment. It is then about continuous dosing, with the regulation of material flow. Dosing can be done in two ways: by feeding a fixed layer of material at an adjustable speed, where the material layer is formed by the outlet of the hopper - the so-called a layer or by means of adjustable material feeding on a weighing conveyor through a preceding device, the so-called Pre-Feeder. In the basic application, the material can be fed with the speed set by the operator, but after activating the PID control option, the weighing controller gains the ability to determine the speed of the belt or feeding device to the desired flow.


The belt feeders consist of a belt conveyor with a built-in scale together with the control electronics. The high quality of materials used to build our feeders makes them suitable for use even in the most challenging conditions, where expectations for failure-free operation are greatest. Each of our feeders has a strictly defined length of the weighbridge. Thanks to this, the weighing controller collects information about the weight of material only from a particular section of the belt, and there is no need to weigh the entire feeder, which significantly increases the accuracy of the measurement. Also, the modern designs of weight feeders that we offer consist of several systems that help you maintain, improve efficiency and extend its life. The use of pulses with a large number of pulses allows the speed to be read even at low rates and the feeder reacts quickly to changing feed, changes in the physicochemical properties of the material or a temporary lack of it. The belt guiding systems and gravity tension guarantee longer work without the need for correction in the tension and minimize weight errors associated with changes in the characteristics of transmission belts under the influence of the environment or wear. Depending on the requirements for flow, material or type of industry, we select the type of feeder, width, and length of the belt and the type of hopper. For applications with increased production cleanliness, we recommend dustproof covers or cases.
