Jet centrifugal concentrator
Spiral Concentrator Introduction
Spiral concentrators are a form of gravity separation technology. In a spiral concentrator, water and gravity force particles to move down and out of the concentrate chute. As particles settle through the spiral concentrator, they collect in separate layers and ar......

Heat Engines
A heat engine is a device that takes in heat energy, converts some of it to mechanical energy, and discards the remainder as waste heat. The simplest heat engine consists of a frictionless piston in a cylinder with a movable piston rod. If this cylinder is maintained at a higher temp......

Introduction
Trains and railroads have a long history and an important role in transportation. Nowadays, railway network is an indispensible part of people’s life. From wheeled carts to modern Railcars, trains have been a reliable means of transportation for many years. However, new technologies......
air bearing
Air bearing
An air bearing (also known as an aerostatic bearing or a pneumatic bearing) is a bearing in which a forces between two surfaces are supported by air pressure. In other words, it is a surface effect bearing. The air bearing provides a smooth, low friction and consistent movement on the......
Positioning of parts on axes
Positioning Components of an Axis
An axis is a device used to rotate an object around its center of mass or a point on the axis of rotation. Axes can be used for a variety of purposes in a mechanical system, including support for other components, allowing for the addition of force or torque to t......
The structure and performance characteristics of five types of bearings
Introduction
Bearings have been around for centuries, but in the modern world, their importance is perhaps even greater than it was at the time of their invention. Low friction and high precision bearings are the driving force behind machine tools, industrial robots and precise instruments, which......
hydrodynamic bearings
Liquid Film bearings now play an important role in the more efficient design of many machines and processes. From the early concept of the hydrodynamic bearing the development of liquid film bearing has been steady over the course of many decades.
Today, liquid film bearings are a fundamental ele......
Do roller bearings need oiling?
Roller bearings require lubrication
Roller bearings are found in many applications, such as automotive engines, construction machines, air pumps, bicycles, skateboards, and many other items. Roller bearings are made up of two pieces: an outer race, which is the outer part of the bearing, and an i......
