A calcining furnace (or a calcination furnace) is a special type of heat treating furnace that evaporates moisture from industrial products. You can also use a calcination furnace for chemical decomposition of metal ores. Traditional calcining furnaces are continuous pusher calcining furnaces, plate type conveyor calcining furnaces or rotary retort type calcining furnaces. Modern calcining furnaces include a mesh belt furnace or a fluidized bed furnace.

You can use industrial calcining furnaces for heat treating ceramic products of porcelain, titantes, steatites, alumina and glass. You can also use an industrial calcination furnace for heat treating metals and alloys. Other applications of calcining furnaces include refining of ferrous and non-ferrous ores.

Some important parameters you must consider before purchasing a calcining furnace are:

1. Temperature range for the calcining furnace
2. Required capacity of the calcining furnace
3. Production requirement: batch wise or continuous
4. Material and dimensions of the components

Action Steps
The best contacts and resources to help you get it done

Buy a furnace from a reputable calcining machinery manufacturer

Once you know your requirements, evaluate different products available with calcining furnace manufacturers.

I recommend: Procedyne Corp., a reputable furnace supplier, supplies calcining furnaces. You can also buy a mesh belt furnace at Prestige Thermal Equipment, another reliable calcining furnace supplier. If you need an electrically fired calcining furnace, look at the different furnaces offered by CM Furnaces.

Buy a calcining furnace from distributors or retailers

You can compare different calcination furnaces based on their features and prices at a distributor or retailer's website.

I recommend: You can check out different furnaces available at S & S Furnace Sales, a reputable furnace distributor. You can also locate calcining furnace suppliers on ThomasNet.

Buy a used calcination furnace

As a furnace is an expensive investment, you can opt for a used calcination furnace for a cost-effective solution. Before buying a used furnace, make sure you opt for a good quality product with a warranty.

I recommend: Machinery & Equipment Company, a used equipment dealer, supplies calcining machinery to the metal processing industries for operations such as smelting, centering and incineration. You can buy a used calcining furnace at Used-Line.com. Thermal Product Solutions is another furnace supplier that offers used furnaces, including calcining furnaces.

Buy a specialty or customized calcining furnace

If the standard industrial calcining furnaces available in the market do not meet your requirements, then opt for customized calcining furnaces.

I recommend: Thermcraft is a reputable furnace manufacturer that provides a rotary tube calciner furnace. In addition to a broad array of standard heating equipment, Pyradia offers customized products, including calcining furnaces. Carbolite offers custom designed calcining furnaces for laboratory and industrial applications.
