In recent years, many experts have studied the motion state of the materials in the ore milling equipment. The ore milling equipment is one of the most common machines used in mining machinery. As a result, the study on the motion state of the materials in ore milling equipment has great significance. The experts of Mining Machinery think that the motion state of the materials in the rotary is related to the size and the rotating speed of the ore milling equipment. We can get the critical speed of revolution of the materials in each state status under different test conditions through the calculation of the criterion number. In order to reduce the power consumption of the materials in the kiln body, we must choose the critical point in certain rank.
In the engineering practice, back fall and tumble with low speed of the materials in the ore milling equipment often appear under different operating conditions of ore milling equipment. The other state modes have higher requirements on the rotating speed of the ore milling equipment, which may endanger the operational safety of the ore milling equipment drive for the large-scale industrial ore milling equipment. In addition, the power consumption to drive the ore milling equipment is large. Therefore, for the industrial ore milling equipment in the actual operation, the centrifugal movements are not used. Since the tumble movement can better make the materials fully contact with the air in free space and improve the gas-solid reaction efficiency, the tumble is the best motion state for the materials in the ore milling equipment. In addition, the operation of the tumble movement is stable as the ore milling equipment, which can reduce the energy consumption of the ore milling equipment. So far, almost all the test studies and the model studies about the materials in the ore milling equipment are carried out based on the tumble bed.
The study on the motion state of the materials in ore milling equipment is very important for the better practical use of the ore milling equipment. Only we have a better understanding about the ore milling equipment can we use it to create more profits for us.
With the development of our industry, the implementation of environmental policy as well as the improvement of human living environment, fly ash, which produced by the thermal power plant has also become an important raw material for the cement industry and building materials industry, and its processing field and utilization of fly as hare greatly expanded.

At some cement factories, construction waste crusher bearing is likely to be burned, which belongs to major accident. The main reasons for it are foreign materials entering into bearing or the poor lubrication system. In some cases, it can lead to damage to hollow shaft neck of bearing. Once burning occurred, it needs over ten hours or even a couple of days to repair. In order to solve construction waste crusher bearing lubrication and management problems, people keep on researching sealing modes, installation technology and lubrication measures to guarantee bearing running in good condition. Here, we take 02.2mx6.5m construction waste crusher as an example, talk about the oil lubrication of bearing.
Generally, cement plants often choose dynamic pressure lubricating method, which is major I will discuss in this article. At first, we should choose proper lubricating oil as well as additives, so that improve milling machine lubricating condition. The work features of construction waste crusher bearing are large overload and linear velocity, suffering from impact and vibrating; the size of bearing bush and hollow shaft is also big, the improvement of shape, size, accuracy and smooth degree are effected by manufacturing conditions. Therefore, main bearings do not guarantee total liquid lubrication, but in boundary lubrication conditions. Excellent boundary lubrication (depending on the performance and strength of boundary film) can significantly reduce the coefficient of friction, reduce bearing wear. So, according to temperature, linear velocity of hollow shaft, and main bearing overload, we can make a favorable choice to lubricating oil type. In south China, as for this type construction waste crusher, we can choose N220 and 0320 industrial gear oil in winter and summer respectively. On the other hand, due to discharging port temperature is higher than that of feeding mouth, we might take it into consideration that high viscosity oil can be chosen as lubricating oil for bearing at the end of discharging port.
Secondly, depending on regular use period, we should add or replace lubricating oil at regular time and proper amount. Besides, lubrication oil management and waste oil recycling is also an important work.
Thirdly, we should establish a perfect construction waste crusher check system. construction waste crusher worker shall check main bearing temperature, oil quality and oil amount regularly. Especially when it comes to abnormal oil temperature, the worker is suggested increase check frequency. He should report in no second once found machine abnormal.
To a large extend, construction waste crusher malfunction is caused by no proper lubricating of main bearing. As cement machine develops to the direction of large scale and automatic, it is necessary to make out a thoughtful predictive maintenance plan.
At present, the construction waste crushers in China annual discharge about 0.4 billion to 0.5 billion tons, taking account one third of industrial waste. Among them, metal construction waste crushers take 25%, metallurgical slag takes 26%, chemical slag takes 4%, coal fly ash and coal slag take 35%. Metal recycling and processing will no doubt use construction waste crusher and other matching equipment. construction waste crushers process makes use of gravity and magnetic concentration production, so as to recover iron ore from ore slag. As for different metals recycling from tailings, we have to use spiral tank, shaking table and construction waste crusher matching with different ore dressing process. For the time being, the advanced equipment such as disk construction waste crusher for weak magnetic field, drum construction waste crusher with big drum diameter for medium magnetic field and high gradient construction waste crusher have been applied to metal concentration process.
construction waste crusher is a new type of high efficiency magnetic separation equipment which produced by Zenith mining machinery company. The whole magnetic system made up of high performance rare earth Neodymium Iron Boron materials and high quality ferrite materials. A cleverly open magnetic circuit design makes the highest magnetic induction in tube sheet selection field be up to 0.8T, which is 3-5 times of the conventional magnetic machine. The magnetic force in magnetic selection field can achieve strong electromagnetic construction waste crusher level.
In the process of iron concentrate powder production, concentration factories will spend 5 to 7 tons water when producing 1 ton ore. If calculated according to 6,000 tons ore production a day, the daily water consumption is about 3,500 tons. In order to save water to maximize, mining and processing plant produced construction waste crusher. This kind of construction waste crusher makes discharged tailings precipitate in the thickener and thick pool successively. The clarified water can be sent to workshop by high pressure water pump and used once again. It achieves wastewater zero discharge in the production.
construction waste crusher saves water without secondary pollution. In the operation, the machine spends less power than other magnetic selecting machine. And it doesn’t need exciting current consumption. construction waste crusher is high treatment capacity as the open magnetic circuit design. It has no clogging problem when runs. As the magnetic system is protected by roller drum from directly contacting with materials, the equipment is low running cost. Besides, it adopts dynamic magnetic system, the magnetic materials are sliding on drum surface, which is good for drum cleaning. Moreover, drum doesn’t attach materials, which is good for improving fine ore grade.
