Volumetric feeder provides low cost and easy option in batch or continuous applications, especially when the bulk density of the fed material is consistent or when precise feed accuracy is not so important for the quality of end product. Frequently volumetric feeder is used in gain-in-weight batch application since higher accuracy can be achieved. When process requirement is more demanding, volumtric feeder with gravimetric scale and loss-in-weight control can be used.
Our volumetric feeder can provide reliable and stable performance. Single screw feeder is the best choice for free flowing materials, while twin screw feeder is the the best solution for difficult-handled materials. We have a full range of volumetic feeders with a number of models and different-sized hoppers to meet your specified requirements.
Twin-screw volumetric feeder is applied to provide accurate volumetric feeding for poor flowing powder, fiber and flake materials.
All parts which contact fed material are made of stainless steel. It is easy to disassembled for cleaning or changing parts. The special bowl-shaped hopper makes material flow from all directions into the screw evenly. It can also avoids material build-up and make feeding more accurate.
Two types of hopper, symmetrical or asymmetrical, can be chosen.
The standard construction material of hopper is SS304. SS316 and SS316L are optional to be used.
For poor flowing materials which tends towards bridging, a vertical agitator is optional to add.
For different environments, different construction materials of screw can be used. The screw materials can be SS304, SS316L, copper, carbon steel and Hartz alloy.

Applications
When the bulk density of the fed material is not consistent, or when the precise feeding accuracy is critical to the end product quality, the loss-in-weight feeder needs to be used. The loss-in-weight feeder can be used in batch or continuous situations. Frequently it is applied in continuous processing, such as extrusion. During extrusion process, multiple ingredients` ratio needs to be controlled precisely.
Characteristics
Our loss-in-weight feeder can provide high precise, reliable and consistent feeding performance. Single screw loss-in-weight feeder
Is the best choice for free flowing materials, while twin screw loss-in-weight feeder provides the best solution for difficult-handled materials. The loss-in-weight feeders are available with a full range of models and different sizes of hopper. It can satisfy the feed range of 0.5-1000L/hr.
Load Cell and Gravimetric Control System
High precise technology is adopted in gravimetric feeder. Our weighing module provides slipt second and milligram range performance. It is designed to be used in harsh industrial environment. Equipped with the first class soft ware, our loss-in-weight feeder can provides consistent, precise, reliable and repeatable results. The gravimetric controller and operation interface allows for individual unit and recipe control. Each feeder has its own control board. The control board and the operation interface is connected by industrial protocol.
The online controller can combine the motor driver with the feeder controller together. HMI provides extreme flexibility for recipe storage and memory. Up to 8 feeders can be working together simutaneously and be connected to DSC system of the main processing machine.
Single Screw Loss-in-weight Feeder
Our single screw loss-in-weight feeder can provides high precise,high valued feeding for pellet, granule, free flowing powder and other bulk materials. The feed rate is 0.5-1000L/hr. The accuracy can reach ¡¡¡ì¡¨¨0.2%.
According to the characteristics of different fed materials, the single screw loss-in-weight is available with a wide range of interchangeable screws.

Application
Liquid loss-in-weight feeder is designed to provide gravimetric feeding of
liquid materials.It is most frequently applied in continuous processes,such as
feeding a compounding extruder where difficult flowing liquids must be
metered at precise feed rates. These liquids are often waxy or viscous and
must be heated to flow properly.
Characteristics
¡ï consists of a storage tank mounted on a high accuracy scale designed for
industrial applications.
¡ï The liquid is metered by a pump positioned off the scale so that only the
liquid and its container are weighed.
¡ïIf the temperature of the liquid to be fed must be maintained at a constant
level, a strip heater or transfer heater using oil or water may be employed.
¡ï When using a strip heater, temperature is controlled by a thermostat and a
safety thermostat. An insulating jacket is placed over the strip heater. The
connecting line is also heated and thermally insulated.
¡ï When using heat transfer, the tank is double-walled and filled with oil or
water.
¡ï The sophisticated load cell provides split-second, high precision weighing
in the milligram range and is specially designed for harsh industrial
environments.
¡ï Liquid feeders are easily integrated with gravimetric bulk solids feeders.
The gravimetric controller and operation interface allow for individual unit
and recipe control. Each feeder has its own control board. Connection
between control boards and operation interface is supported by industrial
protocol.

Single screw volumetric feeder is applied for pellet, granule and free flowing powder to provide volumetric feeding.
A series of interchangeable screws are available for our single screw feeder to meet the requirements of different materials being fed. The feeder is placed on the painted steel plate. All the feeder parts which contact fed material are made of stainless steel. The volumetric feeder can be disassembled easily for cleaning or changing parts. There are two types of hopper shape: symmetrical and asymmetrical. The hopper design can allow material from all directions to flow evenly to the screw, which can avoid material build-up and make feeding more accurate.
The most suitable screw type is determined by the characteristics of fed materials. Therefore, please provide detailed information about your material when inquiring.

Characteristics:
1. Nice Appearance. Compared with traditional feeders, many improvements have been made in our appearance of our feeders.
2. Small Volume. Since it is small, it can be moved to a new place easily, especially when production process is changed or when production technology is improved.
3. Low Noise. Our feeders make almost no noise.
4. Convenient Cleaning and Easy Maintenance.
5. Extremely High Stability. In order to ensure precise feeding in a long run, self-detecting function is included in our feeders, which can detect mechanical wearing and the effect on feeders when frequency fluctuates, then make real-time correction accordingly. Therefore, feeding precision won`t be affected when a mechanical part is replaced or when it is being used for a long time.
6. Friendly HMI. Easy operating touch screen system. Input to the system is more humanized. An operator can master all the operations in only a few hours.
7. Wide Range. Without replace a new mechanical part, a wide range flow rate can be set. In this way, a new manufacturing technique can be shifted to quickly.
8. Excellent Control System. According to customer`s requirement, a control system can control multi-feeders while the feeding accuracy will never be affected.
9. Screw Options. Depending on the fed materials characteristics, interchangeable screws in different shape and materials can be chosen.
