Jaw crushing plant can be used as the primary crusher to themedium size crushing of various ores and large-size materials, withthe anti-crushing pressure of less than 320Mpa. And the crusher can bedivided into two kinds such as coarse and fine crushing. And this series of crusher have complete specifications with the feedingparticle size of 125mm-750mm, which have become the primary crushing equipment. And the jaw crusher machine can be used in the field of mining, metallurgy, building material, highway, railway, water conservancy and chemical, etc.
Before purchasing and using jaw crushing plant, customers should recognize the common knowledge aobut it:
1. Common Parts:
Temperature of eccentric shaft should not exceeding 60 degrees when in work,and the motor 55 degrees. Always check the size of the discharge , if substandard adjust immediately. Bearing temperature can not be too high, if it is too high,stop to check the reason immediately.
Before add the material into jaw crusher and normal start it, jaw crusher should idle for a period of time so as to avoid the machine has some problem just in case,and it is difficult to check it with materials; Before stop the jaw crusher,you should first stop the feeding, and only when the material in crushing cavity are excluded, can we turn off the power, thus do not easily lead to the blockage of crushing cavity.
According to the place of use, temperature and other conditions to determine the lubricating,for example: If there is possible for dry oil solidification in winter you can add 20:6 (by weight) of the automobile oil along the oil, and according to the running situation, fill oil every 1 - 2 days ,as well change a lubricating oil per quarter; timely lubricate the friction surface, such as contact area of the elbow plate and the foot pad should added grease before start the crushing machine.

Rotary kiln, as an important industrial machine, plays important role in various fields. In building materials industry, rotary kiln can be used to calcinate cement clinker as well as clay, limestone and slag dryer; in the production of refractory materials, using rotating kiln to calcinate raw materials could make its dimension stable and strengthen its intensity, and then processing-shaping.
The daily operation and maintenance of rotary equipment can increase rotary kiln life, reduce maintenance costs.
1. Maintenance should work closely with the circumgyrate kiln operation, strengthen contacts. Inspection in the inspection and handling of attention to safety , and some of the projects should operate to stop the kiln.
2. Constant attention horizontal kiln shell temperature calcining kiln cylinder temperature zones can be distinguished recorder infrared scanner is its maximum surface temperature should not exceed 400 ?;
3. The device, supporting device drivers, and a gear wheel systems must often ( every hour ) check and timely handling of noise , vibration and heat and other anomalies found;
4. Notification to activate the auxiliary drive once a week, but do not take the clutch to ensure that it runs smoothly, when the main power supply is interrupted suddenly;
5. Note that if the flow of cooling water flow, wheel tank bottom surface height, you can adjust the water level regulator if highly inappropriate.
6. Check the lubrication point lubrication is normal, should be strictly in accordance with the lubrication system, and check the oil is sufficient;
7. Determine the gap and wear condition, according to the wheel with the relative displacement between the plate and the wheel;
8. Problems found during inspections should be handled in a timely manner and according to the nature of the problem;
9. Note clinker rotary kiln cylinder situation of jumping up and down regularly (jumped up and down once per class);
10. Under the roller cover, check the bearing temperatures and lubrication per hour.

Cement rotary kiln is one essential machine in the cement production process, which also is the heart of the cement production line. Cement rotary kiln can be briefly called cement kiln or circumgyrate cement kiln, which is mainly used for the cement raw material burning. In the cement making procedure, the cement raw material is calcined, mixed and smashed to clinker in the cement rotary kiln. Then the clinker will be grinded and then mixed with some batching to make into cement. So, the key point for controlling the quality of cement should happened on cement rotary kiln. But almost every producer may face the problem that the ring formation and leakage of material may happen to cement rotary kiln. Here Henan Hongxing Mining Machinery Co., Ltd. will give out an analysis of ring formation and leakage for cement rotary kiln.
The main reasons that may cause the rotary kiln ring formation consist: when the contain of sio2 in the ore mesh is higher than Fe2O3, low melting point silicate will be produced, that is so called ring formation; Too high water contain in the coal ash may cause the ring formation because of the incomplete combustion; The incorrect operation caused the temperature of rotary kiln a little high; Check and repair the rotary kiln before cooled down.
Solving measures for the ring formation of rotary kiln: The most easy method to deal with the ring formation is all by artificial. The workers should clean that with instrument in particular time. The ring formation can also be cleaned by calcined, when processed in alternating cool and hot, the ring formation may fall down automatically. When the ring formation of the circumgyrate cement kiln is solved,the sealing problem is obviously solved.If the sealing of the kiln is guaranteed, the leakage of material is also solved at the same time.
Increase the ore ash grade to reduce the sio2 contain in the material; Never feed the material to the rotary kiln until the coal ash is dried; Control the temperature of the rotary kiln strictly and set up the procedure of record and check for the temperature; Check and repair the rotary kiln when it is cooled down.
