    Product Description

    Metallurgical Rotary kiln is one of the products of Rotary kiln, which is mainly used in metallurgy. In addition, we specifically listed the application of metallurgical Rotary kiln, which is mainly used for magnetization roasting of lean iron ore in metallurgical steel plants; Chromium and nickel iron ore oxidation roasting; Refractory plant roasting Gaoye gold mine and aluminum plant roasting clinker, Aluminium hydroxide; The roasting of metallurgical materials such as chromium ore sand and chromium ore powder in chemical plants has a good effect. Common types of metallurgical Rotary kiln include: lithium Rotary kiln, iron Rotary kiln, aluminum Rotary kiln, metal/oxidation Rotary kiln. Lithium ore Rotary kiln is divided into Lithium carbonate Rotary kiln, Spodumene/lepidolite Rotary kiln, lithium battery material Rotary kiln, Lithium iron phosphate Rotary kiln Iron ore Rotary kiln is divided into Hematite Rotary kiln, Limonite Rotary kiln, Ilmenite magnetization roasting Rotary kiln, iron oxide Rotary kiln, lean iron ore oxidation roasting Rotary kiln Aluminum ore Rotary kiln is divided into: aluminum slag Rotary kiln, aluminum oxide Rotary kiln, aluminum ash Rotary kiln, Aluminium hydroxide Rotary kiln, Calcium aluminates Rotary kiln Metal/oxidation Rotary kiln: zinc oxide/secondary zinc oxide Rotary kiln, magnesium oxide/secondary magnesium oxide Rotary kiln, copper ore roasting/reduction/arsenic removal Rotary kiln, gold ore arsenic removal calcination kiln, laterite nickel ore roasting and reduction Rotary kiln, chrome ore and chrome ore powder roasting Rotary kiln, reduced titanium Rotary kiln, other metal calcination/oxidation roasting/desulfurization and arsenic removal Rotary kiln


    Feature

    The axial movement of the cylinder is controllable    
     The kiln shell is made of high-quality killed steel plate welded and rolled. The shell is supported on the support device of the 2-7 gear sliding bearing through wheels, and there are mechanical or hydraulic blocking wheels on one or several of the support devices. Customers can flexibly control the axial movement of the shell.


    The transmission device rotates the cylinder at the required speed through a gear ring located in the middle of the cylinder. The main drive adopts a frequency conversion motor, which is convenient for smooth adjustment of the speed of the Rotary kiln body. The motor power of the auxiliary transmission system is 15-75kw, ensuring smooth operation during kiln operation.


    Easy installation and maintenance  
    Larger kilns are equipped with auxiliary transmission devices that rotate the cylinder at a very low speed, meeting the needs of installation and maintenance.


    Good sealing performance    
    To prevent cold air from entering and smoke and dust from overflowing the cylinder, reliable sealing devices are installed at the inlet (tail) and outlet (head) ends of the cylinder for the kiln tail and kiln head.


    Working principle



    Raw ore is directly fed into the Rotary kiln tail from the storage silo via electronic belt metering scale, belt conveyor, stabilizing silo and air lock valve. Only stabilizing silo is set at the kiln tail to reduce investment. The ore is heated in the first row of the Rotary kiln, and the raw ore moves in reverse with the hot gas flow in the kiln. After the raw ore is heated to the reduction temperature in the heating area, it enters the reduction area. The temperature of the flame center in the reduction zone is controlled at about 1000 ℃, and the temperature of the hot atmosphere in the reduction zone is controlled at about 700 ℃ to react with the reduction gas and reduce to Magnetite. Afterwards, it enters the cooling zone and meets the incoming gas. The gas is preheated, and the ore is cooled before being discharged from the kiln. After being cooled by a continuous bucket conveyor, it is then stored in a storage tank for selection.
