Most mineral processing kiln production lines are often used in one kind of processing equipment, the dressing process, a rotary kiln roasting magnetic iron grade ore, the ore is changed to the original weak magnetic ferromagnetic facilitate magnetic separation. According to the use of rotary kiln, several problems caused by the rotary kiln in the beneficiation production line are summarized.
First, pitting and peeling off. The belt is often supported by the roller, and the contact between the roller and the belt is to generate a large Hertzian stress. This stress is a local high stress, and the wheel will generate fatigue under the long-term action of the pulsating stress. Pitting corrosion, after the pitting is enlarged, will cause large-scale peeling. For example, the peeling area of ​​Xiangfan Xinsanli Cement Co., Ltd. is as large as 360×1200mm2.
Then peel off and crush. The material of the wheel belt is generally carbon cast steel or 35SiMn, 42CrMnSi and other materials. Due to the defects of casting, the axial hardness of the wheel belt is uneven and the structure is inconsistent. Under high load, the structure of the wheel material is loose, and the place with low hardness has crushing, curling and compression. In addition, due to casting defects, subcutaneous voids, large areas of looseness, blisters, etc., can also cause spalling and indentation.
Finally broken. The radial or axial fracture of the wheel belt is completely broken in the radial direction, the inner arc changes, the field is difficult to repair, the axial crack is not completely cracked, and the method can be repaired.
Flame heater is a kind of equipment that uses the heat energy generated by the combustion of flame to heat. It usually consists of a fuel supply system, an ignition system, a combustion chamber, a Heat Exchanger and an emission system. The fuel supply system usually uses liquefied gas, natural gas or diesel as the fuel, the ignition system is used to ignite the fuel, the combustion chamber is where the fuel is burned, the heat exchanger is used to transfer the heat generated by the combustion to the heated object, and the emission system is used to discharge the exhaust gas produced by the combustion. Flame heater is widely used in industrial production, construction sites, wild camping and other occasions, has the advantages of fast heating, high efficiency, easy operation and so on.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects.
