Twin screw volumetric feeder

Twin screw volumetric feeder

Twin screw volumetric feederIt is a device used for controlling and measuring material flow, widely used in industries such as chemical, pharmaceutical, food processing, plastic processing, and building materials.

1、 Working principle of twin-screw volumetric feeder

The working principle of the twin-screw volumetric feeder is based on the volumetric measurement of materials. It usually consists of a hopper, a measuring chamber, and a discharge port. The material enters the measuring chamber from the hopper, and the volume of the measuring chamber is fixed. By controlling the residence time of the material in the measuring chamber, the flow rate of the material can be accurately controlled. When the material in the measuring room reaches the set volume, the discharge port opens and the material is transported to the next production process.

Twin screw volumetric feeders are widely used for various materials, including providing volumetric feeding solutions for powder, fiber, and sheet materials with poor flowability.

2、 Main components of twin-screw volumetric feeder

1. Hopper: used to store materials to be fed.

2. Measurement room: a fixed volume container used for measuring materials.

3. Discharge outlet: a channel that controls the outflow of materials.

4. Drive devices: such as motors and reducers, used to drive spiral blades or belts, etc.

5. Control system: including sensors, controllers, and actuators, used to monitor and regulate material flow.

All components in contact with the material are made of stainless steel. This feeder is easy to clean and replace components. The spherical hopper design ensures that materials flow evenly from all directions into the screw, effectively preventing material accumulation. Horizontal mixing further improves the flow of materials towards the screw propulsion section, making feeding more precise. When feeding materials with poor fluidity and easy bridging, vertical mixing can also be considered.
