Rotary valves (also known as airlocks, rotary feeders, or airlock feeders) are used to transition material from one pressurized point, such as a dust collector, to another unpressurized point, such as a drum or bin. Rotary valves help seal a pressurized system against loss of air and pressure. Rotary valves also ...
Even though a rotary airlock valve is a relatively simple device, you have to maintain it properly to ensure it performs dependably. ...
A Midwest based brake manufacturer had (2) 50 HP Central Vacuum Systems for the recovery of brake dust, operating at a 16” HG vacuum. They were using Rotary Airlock Valves on the material discharge. The Rotary Valves were leaking excessively, and were a constant maintenance issue. ...
After taking part in Meyer’s free consultation to determine the correct valve needed for the application, it was no surprise the energy company moved forward with replacing the double flapgate valves with Meyer’s HDX rotary airlock valves. ...
Overview A North American catalyst supplier was experiencing excess leakage from the dual 18" rotary airlock valve series in their dilute phase pneumatic conveyance system supporting a high temperature alumina application. ...
Preventing operating problems by maintaining your rotary airlock valve Even though a rotary airlock valve is a relatively simple device, you have to maintain it properly to ensure it performs dependably. ...
It is important to maintain tight clearances; this allows the airlock valve to effectively create a seal, while maintaining a flow of material between components with different pressure. ...
The featured image in the article shows two, Meyer Stainless HDX Rotary Airlock Valves above the cutters and below the gravity diverter. It states in the article “if material backs up, it will strain the cutter bearings, causing them to overheat and possibly fail. To ensure an even flow, a mechanical flow control valve [Meyer HDX] was ...
The CO2 is usually contained within the fermentation tank; however, the carbon dioxide could escape through the tank's airlock and valves. CO2 is heavier than air, so it can rest on the brewery floor where staff breathe it in. ...
Because the material continuing downstream ("carry-over") must be accumulated, and air vented from the system, the pneumatic line downstream of the scale valve is normally routed back toward the material source (such as a bulk bag unloader) into a filter receiver with a rotary airlock valve that reintroduces the material into the pneumatic line ...
Suspension Burning For Precalciner Kilns Traditional Feed Shelf method using Double Gate Airlock Valve to feed whole tires Suspension Burner method suspends whole tires in calciner or riser duct Figure 1 Challenges Precalciner kilns have observed limited results with the use of feed shelf firing primarily due to excessive sulfur ...
