How to Bond Stainless Steel - Permabond
Stainless steel or "inox steel" is a steel alloy containing chromium. It does not corrode, rust or stain like normal steel. It normally is quite easy to bond and does not require much in the way of surface preparation, however, mirror-finish stainless steel can have a very low surface energy and prove difficult to bond.

Ball Valve - an overview | ScienceDirect Topics
The ball valve is an inexpensive alternative to other valves. Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low flow situations.
Uses of Graphite - Refractories, Batteries, Steel Making ...
The separation process from graphite, however, requires more technological development. Refractories . Before 1900, the use started with the graphite crucible to carry molten metal but now it is a small part of refractories. The carbon-magnesite brick became important in the mid-1980s, and the alumina-graphite form became a little later.
Ball Mills - Mineral Processing & Metallurgy
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Ball mills are commonly used for crushing and grinding the materials into an extremely fine form. The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.
Cement mill - Wikipedia
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Types of Industrial Valves - Applications, Advantages, and ...
3. Ball Valves. As the name suggests, ball valves are valves that use a ball to control the flow of substances from one opening to the next. These valves work by allowing the hole to be open, blocked, or open partially to regulate the flow of gas/liquid. Ball valves are the ideal choice for using with gases as they are able to offer better sealing.
