DZTSeries rotary drumcalcinationmachine

Equipment Overview:

In many production industries such as building materials, metallurgy, chemical engineering, and environmental protection, rotary kiln equipment is widely used for physical or chemical heat treatment of solid materials. This type of equipment is called rotary calcination kiln. Mainly used for magnetization roasting of poor iron ore in metallurgical industry steel plants; Oxidation roasting of chromium and nickel iron ores; Refractory plant roasting high alumina vanadium ore and aluminum plant roasting clinker, aluminum hydroxide; Chemical plants roast minerals and chemical products such as zinc oxide, chromite sand, and chromite powder. Lime kiln (i.e. activated lime kiln) is used for roasting activated lime and lightly burned dolomite used in steel plants and ferroalloy plants. Our company producesDZTThe external heating rotary calcination furnace is an improved version of the conventional external heating rotary dryer, with an operating temperature of300℃～1100℃, it has the advantages of simple operation, easy maintenance, long service life, low energy consumption, and wide applicability. Widely used in the calcination of products in industries such as metallurgy, building materials, chemicals, feed, and mining, and can also be used for product drying.

Working Principle:

The material is transported to the feed chute at the kiln head and enters the rotary drum through the chute, where it effectively contacts the drum wall and undergoes heat transfer and exchange. The material is first dehydrated and dried, and then heated to a certain decomposition temperature before starting to undergo calcination and decomposition. The decomposed gas is discharged by the decomposition gas induced draft fan, and the product moves forward through the slow rotation of the drum and the special form of cutting plate inside the drum, and is discharged from the kiln tail. The decomposed gas contains a small amount of product dust that is captured by a pulse bag filter and discharged from the bottom star shaped discharge machine, while the captured water vapor is discharged into the atmosphere by a induced draft fan.

Equipment features:

1The product has a wide range of adaptability, especially for products that require decomposition reactions or dehydration at high temperatures;

2Simple structure and easy operation;

3High operational flexibility, with a certain range of fluctuations in operating parameters, which will not affect product quality;

4Product quality can be controlled by adjusting temperature, feed rate, and cylinder speed;

5Equipment cleaning is easy.
