Experts from Hongxing Machinery analyze on the optimization rotary kiln in the process of calcining materials. Rotary kiln is widely used to calcine massive, granular or powder to solid material. Rotary kiln provide the reacting space and condition for raw materials, rotary kiln is suitable for non-ferrous metals metallurgy process, such as used for aluminum hydroxide calcination, lead and zinc or zinc leaching residue processing, etc.Kiln calcine system is with much equipment, and weight is big, therefore, steel consumption per unit product is bigger, and the investment is higher.The cement kiln is mainly used to calcine cement clinker; In the process of non-ferrous and ferrous metallurgy, such as iron, aluminium, copper, zinc, stannum, nickel, wolfram, chromium, etc., the rotary kiln can be used to sinter and roast ore, concentrate, intermedium, etc.; The lime kiln is mainly used to calcine limestones.The ownership of all the information including the photos and product specifications belongs to Great Wall Heavy Industry, If reproduced, please indicate the original source and the statement of the enterprise, any infringement may lead to the civil,administrative or criminal responsibility.Rotary kiln is the host equipment in cement calcination plant, cement production line capacity are based on rotary kiln performance, and the rotary kiln working condition has close relationship with refractory materials. Production process stability and masonry construction quality also affect the service life of rotary kiln refractory and the rotary kiln normal operation. Rotary kiln lining refractory has the functions of protection rotary kiln shell, reduce kiln shell heat loss, stable thermal system and improve calcining kiln capacity etc.Refractory has different functions in different rotary kiln section and refractory has the following features; refractory not melt at high temperature for a long time and keep stable strength, refractory does not cracks and peel off under variable temperature and kiln stop for maintenance. http://www.sell-ballmill.com/pro/rotary-kiln.htmlhttp://www.hxjqmining.com/pro/cemen_rotary_kiln.html
