FAQ
1. What is a loss-in-weight screw feeder?
A loss-in-weight screw feeder is a device used to control the flow of materials in the plastic/chemical industry. It consists of a screw that rotates at a controlled speed, and a weighing system that measures the amount of material being dispensed. The feeder is designed to operate continuously and to maintain a constant flow rate of material.
2. What kind of materials can be used with the feeder?
The feeder is suitable for use with a range of materials, including powders, granules, flakes, and liquids. However, it is important to select the appropriate feeder design and configuration to ensure that the specific material being fed can be handled effectively.
3. What is the precision error of dosing with the feeder?
The precision error of dosing with the feeder is typically less than 0.3-0.5%. This means that the feeder can deliver highly accurate and consistent dosing of materials.
4. What is the weighing resolution of the feeder?
The weighing resolution of the feeder is typically 1 per 4 million. This high level of accuracy ensures that even small amounts of material can be dispensed precisely.
5. What kind of control unit does the feeder use?
The feeder uses a microprocessor control unit, which allows for precise control of the feeding process. It also enables the feeder to be integrated with other systems and equipment in the production line.
6. What communication interfaces are available with the feeder?
The feeder is designed to be compatible with multiple industrial fieldbuses, so it can easily be integrated into different types of production environments.
7. What kind of driven element does the feeder use?
The feeder uses a servo drive, which provides accurate and efficient control of the screw speed and feeding rate. This technology enables the feeder to operate reliably and smoothly, even at high speeds.
8. What materials is the feeder made of?
The feeder is typically constructed from high-quality materials such as stainless steel and aluminum, which are durable and resistant to corrosion.
9. What is the power consumption of the feeder?
The power consumption of the feeder ranges from 0.2kW to 1.8kW, depending on the specific model and configuration. Customized power supplies are also available if required.
