The application of rotary kiln in ore beneficiation plant: During the ore dressing process, there are often some weak magnetized rockraw materials which are not easy to be separated with the magnetic separation. Then using the rotary kiln to calcine such materials toincrease the magnetism, the materials are conducive to further magnetic separation. For this reason it can also be mineral rotary kiln and ore rotary kiln. But do you know How to Test Run for Lime Rotary Kiln Well?
After lime rotary kiln equipment installation, check whether equipment of various technical indicators are up to par, confirmed by the relevant department qualified rear can debug and test run.Before the commissioning of cement rotary kiln and affiliated facilities to conduct a comprehensive inspection: (1) ensure that all fastener tighten and firm, clean up the lime pit outside, all up and down the basis of sundry, especially between belting leather and tug between gear, etc.; (2) check the lubrication of cold whether there is leakage, the valve is flexible and reliable hydraulic system, filling the oil in place, oil pressure, oil temperature, flow rate meets the design requirements; (3) check all instrument, indicator and motor direction of rotation, and conform to the relevant drawings and regulations; (4) check the transmission device, can not have shock, vibration, abnormal noise, large and small gear meshing to normal, work smoothly,(5) check if belting leather and tug to keep normal contact, contact length not less than 70%, move, the breakthrough on kiln cylinder shall be carried out smoothly; (6) to check whether there is loose phenomenon, various device sealing device and partial phenomenon whether there is friction.
The specifications whether meet the requirements, such as equipment debugging, debugging when debugging was carried out on the main motor, at the same time open cooling and lubricating system, finally driven by main motor drive system of lime rotary kiln working 8 hours, confirm that all the equipment operating normally have no problem.

Ore feeding mahcine is also known as grizzly feeder, shaker feeder or vibration feeder, and also can be called mineral feeding machine in the mining operation. It is a kind of dosing device, generally used for quantitatively and evenly feeding granular or powdered materials to other devices and also is widely used in beneficiation process used.
Vibrating feeder is composed of feeder groove, exciter, spring bearing, gear etc. the vibration source of the groove feeding vibration is exciter, exciter is composed of two eccentric shaft and gear. the motor through the triangle to drive the active axis. The up gear of the active axis drives the passive-axis with rotating, active and passive axis reverse rotation at the same time, make the body vibrate and continuous flow of materials, to achieve the purpose of conveying materials.
The mineral feeding machine produced by Henan Hongxing Mining Machinery Co., Ltd. can be classified into the structure of steel plate and grid section, and the mineral feeding machine with the structure of steel plate can be used in the sand and gravel production line in order to feed the material into the crushing machine wholly and stably; the ore feeding machine with the structure of grid section can be used for coarse screening, which has become one invincible mining machine in the crushing and screening equipment with one advantage of the reasonable arrangement.
The ore feeding machine is installed on the bottom of the ore bin outlet, the ore fall onto the leakage board at the chute bottom, the bottom of the leakage board is fixed on the idler, and through the eccentric institutions to connect the leakage board and the reducer together, and then through the coupling lined the motor. During the operation the motor drive the reducer through the coupling, and through the eccentric dish and the leaking plate, which is at the bottom of the frame also between the idlers, to move in reciprocating linear way, and achieve the feed uniformly.

Ore Rotary kiln in operation process, over time the parts will be wear and tear, thus reduce reliability during equipment operation, and even affect the production of rotary kiln, therefore must borrow overhaul chance to recover. According to the maintenance work load, overhaul, repair, and minor repairs.The use of factory according to the operation and maintenance of rotary kiln for large, medium and minor repair plan. Focus on small repair and obtained. Repair work of lime pit can be stopped when lime rotary kiln lining replacement, only allow overhaul drive at the end of the bricklaying.
But should also in the short term (e.g., 8 to 12 hours) done quickly. For overhaul requires a long time, when all the spare parts need to change the kiln, check and adjust the whole device (for example: change the kiln shell section; replace the big gear ring, belting leather, roller, kiln head of lime pit, sealing parts, etc.), but must pay attention to, in front of the plan to stop kiln, all need to change the spare parts and special tools shall be complete in order to reduce maintenance time.Roller tile ball wear: Ore Rotary kiln in the process of running, the bowl the ball wear caused by the bearing fracture, problem, traditional methods cannot be effectively repair site, replace the new spare parts need high cost, not only need to wait long downtime and spare parts, will cause great losses to the enterprise.
2211 f polymer metal repair material has strong adhesion, excellent comprehensive properties such as compressive strength, the beautiful ka wah - f the blue 2211 f metal repair material, can avoid machining field fast repair tile ball wear.No repair welding thermal stress effect, repair the thickness is not restricted, and the product of metal materials do not have rolled back, to absorb the impact of vibration equipment, and can make the matching surface contact, 100% avoided again the possibility of wear and tear.
