Flanges types

Installation of propeller-type mixers varies greatly, depending on the specific application. Top-entering mixers utilize either a clamp- or flange-type mounting. It is important that the mixer be installed so the propeller or paddle placement is at a point within the tank, vessel, or piping that assures proper mixing. Vendor recommendations found in O M manuals should be followed to ensure proper operation of the mixer.

In these extruders, six or more evenly spaced planetary screws revolve around the circumference of the central or so-called sun screw. The planetary screws intermesh with the sun screw and the barrel. The planetary barrel section has helical grooves corresponding to the helical flights on the planetary screws. This section is usually a separate barrel with a flange-type connection to the feed barrel section. 

Design of railway wheels were indeed challenging as they ran on rails. In the beginning of nineteenth century, rack-type tracks were developed on which a toothed wheel moved. However, it was difficult to use toothed wheels on rails. It took considerable efforts and experiments in the design of wheels for rails to realize that smooth rails in contact with the wheel rim could give sufficient friction to run the trains. Two types of wheel-rail combinations were initially used—flanged type...
