In metallurgy, a ladle is a barrel or vessel used for transporting and pouring molten metal. Ladles are commonly used in foundries and range in size from small, hand-held containers resembling kitchen ladles and holding 20 kg (44 lb) to large ladles weighing up to 300 tons (295 l

Ladles can be of "lip pour" design, "teapot spout" design, "lip shaft design" or "bottom pour" design:• For lip pour designs, the ladle is tilted and the molten metal is poured from the ladle like water from a pitcher.• Teapot spout design, like a teapot, draws liquid from the bo

A stacker is a large machine used for bulk material handling. Its function is to stack bulk materials such as limestone, ore, coal and grain on the stack. A recycling machine can be used to recycle materials.Gold mining dredgers in Alaska have a stacker which is a fixed part of the dredger. It trans

Bucket wheel reclaimers use "bucket wheels" to remove material from the piles they recycle. A scraper reclaimer uses a series of scrapers on a chain to reclaim material.There are many types of reclaimer structures, including portal and bridge. Reclaimers are named according to their type, eg "bridge

Induction heating is the process of heating a conductive material (i.e. metal or semiconductor) by electromagnetic induction, by transferring heat through an induction coil, within which an electromagnetic field is generated to heat and possibly melt steel, copper, brass, graphite, gold, silver, alu

CookingIn induction cooking, induction coils inside the cooktop heat the iron base of the cookware through magnetic induction. Using an induction hob is safe, efficient (the hob itself does not heat) and speed. Non-ferrous metal pots such as copper bottom pots and aluminum pots are generally not sui

A clothes dryer, also known as a tumble dryer or simply a dryer, is a powered household appliance that is used to remove moisture from clothing, bedding, and other textiles, usually after being washed in a washing machine.Many clothes dryers consist of a rotating drum called a "tumbler" through whic

Spin dryersThese centrifuges simply spin the drum much faster than a typical washing machine to extract more water from the load. They can remove more moisture in two minutes than a heated tumble dryer can in twenty minutes, saving a lot of time and energy. While spinning alone doesn't completely dr

Air separation plants separate atmospheric air into its main components, usually nitrogen and oxygen, and sometimes argon and other rare and inert gases.The most common method of air separation is fractional distillation. Cryogenic Air Separation Units (ASUs) are used to supply nitrogen or oxygen an

Pressure swing adsorption separates oxygen or nitrogen from air without liquefaction. The process operates at ambient temperature; the zeolite (molecular sponge) is exposed to high-pressure air, which then releases the air and releases an adsorbed film of the desired gas. Compressors are greatly red
