The hammer quarry crusher is suitable for crushing all kinds of medium hardness and brittle materials. It is used for coal, cement, gypsum, alum, brick, tile, limestone, etc. the material is not more than 300 MPa.
Hammer quarry crusher work principle: the main working parts of hammer quarry crusher with a hammer (also called hammer) of the rotor. The rotor is composed of the main shaft, the disc, the pin shaft and the hammer. Motor drives the rotor in the crushing cavity high speed rotation. Material from the upper feed into the machine, the impact of the high speed movement of the hammer, impact, shear, grinding and crushing. In the lower part of the rotor, with sieve plate, crushing material less than sieve size fractions discharged through the sieve plate, greater than the mesh size of the coarse grained material resistance in sieve plate continue to be a hammer blow and shear, the sieve plate is discharged out of the machine.
Failure and removal of hammer type quarry crusher:
1, Bearing Overheating
Reason: lack of grease; too much grease; lubricating grease deterioration; bearing damage.
Rule out method: filling amount of grease; bearing grease should be the space volume of 50%; cleaning the bearings; replacement of grease; replacement of bearings.
2, the grain size of the material
The reason: hammer wear too large; sieve faults.
Method: to replace the hammer; replacement of screen strip.
3, the yield decreased
Reason: the screen bar is blocked; the feed is not uniform.
Rule out method: stop, clean the plug in the screen, adjust the charging mechanism.
4, elastic coupling produces percussion sound
Reason: pin shaft loose; elastic ring wear;
Rule out method: stop and tighten the pin shaft nut replacement.
5, the machine generates a percussion sound
The reason: the non crushing matter into the inside of the machine; lining plate fasteners loose, hammer impact on the lining board; breaking hammer or other parts.
Troubleshooting: parking, cleaning up the broken cavity; check the fastening of the lining plate and the gap between the hammer and screen; replace the broken parts.
6, machine vibration
Reasons: replacing hammer or for cone head wear of the rotor static balance undesirable; broken hammer, rotor imbalance; pin shaft bending, broken; triangular disk or disk Park crack; anchor bolt loosening.
Troubleshooting: unloading under the hammer, according to the weight hammer, equal to the total weight of the total weight of each branch on the hammer shaft hammer and hammer shaft hammer, namely static equilibrium is achieved; replacing the hammer head; the replacement of a pin shaft; welding repair or replacement; fastening bolt.

China's mining machinery industry is developed from the introduction, digestion and absorption, some enterprises have made some progress in training the capability of independent innovation and achieved a breakthrough, but from the view of the industry as a whole, we still need to significantly improve the ability of independent innovation.
Since China's accessed to the WTO, the sustained and rapid development of China's economy continues to attract many foreign businessmen to join, these foreign investments bring great opportunities for CHINA, but also to bring our national enterprises crisis, especially for machinery manufacturing. The competition has become more intense. Under strong abroad pressure of capital and technical strength, domestic mining machinery enterprises take the innovation awareness. Many of our products claims completely independent innovation, however accessories or the core technology never get rid of the pattern set by foreigners, facing foreign challenge with this quarry crusher equipment is tantamount to suicide.
Zenith makes independent innovation as premise, while it does not abandon the foreign advanced technology; the enterprise R D and produce a variety of equipment: crawler mobile crushing plant, tire type mobile crushing plant, efficient cone crusher machine, VSI sand making machine, VSI5X impact crusher(new sand), VW high-grade stone shaping machine (new sand), CS series, LM vertical mill, MTW European trapezoidal mill, MTM trapezium mill, which adopts the international advanced level of technology and combine with self-developed technology; the finished complete equipment maintains international standards, meeting the actual needs of customers in China market.
Mobile crushing and screening equipment has high performance, high reliability and attractive appearance, it reaches the international level, widely used in road and bridge construction, urban construction, metallurgy, energy, and other sectors.

Based on sand with good performance, structure plus mobile is to make the whole device, a menace. Equipment for quarry crusher can not subject to environmental constraints, to reach any sand demand site, on the site adaptability, convenient, safe and reliable. 

The integration of the entire unit is compact and reasonable, small occupation area, enhance the flexibility of site stationed; the field can be the first line of material crushing, eliminating the middle link of material from the scene to crushing, greatly reduce the transportation cost of material. 

Mobile sand production line of production, closely combining the industry demand by sand, sand making equipment with high performance, can simultaneously on the hard and super hard abrasive material crushing and finely homework, with coarse crushing and fine crushing and screening system this system sand production line, can be stand-alone group work independently, can also be flexible system configuration unit combined operation. 

Mobile sand production line of including mobile jaw crusher, mobile crusher, mobile cone crusher, Raymond mill etc.. Based on many years of production experience, can provide customized personalized mobile production line for the customer, make the sand mining operations can adapt to a variety of field flow in the wild, become the excellent performance of mine off-road equipment.

In recent years, the development speed of Chengdu very quickly, coupled with a strong historical and cultural heritage, is the city's tourism industry to obtain the considerable development, Chengdu sand making machine in the construction industry and constantly got affirmation and application. Originally, in the mineral processing production line of the traditional, sand making machine is not commonly used, thus the question is: the material quality is very low production line, more impurities in the finished material, cause as aggregate material adhesion is not strong, as the coating material is thin and greasy.After gradual development, people found that the sand making machine is a good solution to the problem.

Chengdu is an important gateway to the southwest city, along with the development of tourism, the Chengdu construction industry and related equipment industry has achieved rapid development. The application of all kinds of Chengdu quarry crusher are, because the requirement of service in tourism building decorative material is relatively high. All used for building exterior marble, granite, pebbles, Ishi, terrazzo, hardness, color congruent beautiful and durable stone, broken equipment in processing into the required grain type, often contain a lot of dirt, impurities and powder, if not promptly cleared out, it will lead to the exterior stone can not very good adhesion in the building, or the color is not clear, graded not reasonable etc.
In the decoration of the building materials industry, sand making machine really find direction. Various sizes of ore in the crushing or sand, simple screening, with Zenith specially developed Chengdu portable crusher on the market of decorative building materials quality rapid promotion. Has had an enormous effect, stems from the sand washing device with low cost and excellent performance. Consider the internal member sand making machine is easy to wear, and water pollution problems, Zenith uses the structural layout of good and effective sealing design, avoid bearing damaged by soaking, sand and pollutants. In consideration of washing, dehydration, grade three function, makes the improvement to the equipment engineer, ultimately make the device has simple and reasonable structure, low water consumption, low noise. More importantly, cleaning powerful so that a large number of providing high quality decorative building materials become possible.
