Rotary union - Wikipedia

A rotary union is a union that allows for rotation of the united parts. It is thus a device that provides a seal between a stationary supply passage (such as pipe or tubing) and a rotating part (such as a drum, cylinder, or spindle) to permit the flow of a fluid into and/or out of the rotating part.Fluids typically used with rotary joints and rotating unions include various heat transfer media ...

Cement Kilns: Firing systems

In rotary kilns, irrespective of the fuel used, the most obvious common feature of the firing system is ... The air-stream finally passed into the centrifugal fan chamber and was blown out into the kiln firing pipe. The mill would handle coal up to 18 mm in size. Type "A" Atritors also had a set of pre-crusher swing hammers before the "first effect" hammers, also on the same shaft, to allow ...

A Practical Guide to Rotary Valves

• A Rotary Valve does not create product flow; it can only pass such product that can fall into it and out of it under gravity. • All Rotary Valves leak air (or gas) when the system is operating (regardless of whether there is a pressure differential or not) and this can affect product flow and system performance, especially where the gas pressure below the valve is the greater. • The ...

Introduction to Pneumatic Conveying of Solids

Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics. Why use pneumatic conveying to move bulk solids? With the appropriate choice ...

Understanding the role of rotary valves and venturi ...

A Rotary valve is a compact mechanical device used for continuously charging bulk powders or granules under gravity flow. It is considered the simplest of machines because it only has one moving part and a multi-vane rotor revolving in close contact in the housing. Other parts include an inlet on top and an outlet at the bottom as seen in the image below.

Durham Mining Museum - The Elements of Coal Mining

A pipe, in the upper end of which this valve is placed, passes from the working barrel into the water, and is known as the suction or snore pipe. The upward movement of the bucket creates a partial vacuum in the space below, into which the water rises until ultimately it passes through the receiving valve and into the working barrel. On the down stroke of the bucket the receiving valve closes ...
