What is rotary airlock feeder?

A Rotary Airlock Feeder separates a pressure differential while allowing material to pass through it. Best way of thinking of how it works is imaging a revolving door in a building; it allows material to pass through, but maintains the pressure differential between the building and outside.

What is an airlock feeder?

Rotary Airlock Feeders are valves that prevent the loss of air while transferring dry bulk solids at a controlled rate of displacement. . Though not one-hundred percent airtight, they are precision built, therefore can meter the flow of materials with minimal loss of air.

How is rotary airlock capacity calculated?

To calculate the Rotary Airlock Valve Capacity, divide the rate of conveying by the product density, then divide the result by the valve efficiency, and finally divide that result by the rotor speed.

What are rotary valves used for?

(See blog article “What is a rotary valve?”) In industry, a rotary valve is used to regulate the flow of a product, usually to reduce the flow rate to a level more suitable to the process being undertaken.

How does a feeder seal work?

The seals work by squeezing around the shaft and maintaining a slim layer of lubricant between the lip and the shaft. Rotary Shaft Seals provide hydrodynamic action to aid the seal, creating a slight pump action. Depending on the applications, Rotary Shaft Seals avoid different types of contamination.

What is a star valve?

Rotary valves, also commonly called star valves, are therefore used at the beginning and at the end of pneumatic transports. They allow to bring the solid from a zone of low pressure to a zone of low pressure at the beginning of the line while helping to disengage the solid from the air flow a the end of the line.

What instruments use rotary valves?

Although the most common instrument to use Rotary Valves is the French Horn, Trumpets, Flugelhorns, Euphoniums, Tubas and other brass instruments are also made in rotary valve variations.

How does a rotary valve 2 stroke work?

An airlock-type rotary valve receives and dispenses material from two chambers with different pressure levels. They seal air flow between the valve’s inlet and outlet to maintain a consistent pressure differential, which promotes efficient material flow.
