The properties of rocks have effects on quarry crusher

We should know the nature of rocks before using the quarry crusher. Only understand the properties, can we choose suitable quarry crusher, and avoid using unsuitable crushers.Structure, density, humidity, hardness, strength, flexibility, plasticity, brittle, heterogeneity, anisotropy, porosity, ruggedness, drill-ability, etc, everyone is closely related with the crushing effect.

Rock crushing method, in specifically, is the method to drill various sizes and shades of holes in different performance rock stratum by a variety of mining machines. According to the crushing principle, it can be pided into impact, cutting and impact-cutting three categories. Each category has its own application range. They all have unique features and the same crushing theory. The drill which directly crushes the rock requires reasonable structure and size, as well as suitable pressure, rotate speed and torque. The drill bit must be match with the nature of rocks.

quarry crusher is suitable for crushing rocks such as granite, basalt, river gravel, limestone, andesite, rhyolitic rocks, diorite, diabase, sandstone, etc., which can widely applied to crush mid hardness and large-scale rocks and ores in mining, smelting, building material, highway, railway, water conservancy chemical and other industries.

Abnormal vibration and solutions of quarry crusher

Quarry crusher is new type high efficient crusher equipment, and its welcomed by customers due to its inexpensive price and excellent performance. But quarry crusher has problems of vibration in running. Vibration is inevitable, and any quarry crusher machine will be affected by motor, but vibration with light degree is normal, but too severe vibration will have damage on the machine, so shutdown and check the machine if it is in too severe vibration.

Vibrations can occur because various reasons, and there are several cases that may cause vibrations, such as imbalances, too large material block and so on. Faced with imbalances, the user needs to adjust the rotor. For too large material block, check the feeding size, and ensure that the material meets the size requirements. Underlying incorrect process can also cause abnormal vibration, check and reinforce the anchor bolts can solve this kind of problem. Same degree of wear and tear also causes abnormal vibration, which means the hammer head needs to be replaced.

Raymond mill is a kind of ore milling equipment material by grinding energy. The rotor of mill does high-speed revolution driven by a motor, material will be crushed by hammers after entering the crushing cavity, then be lifted to certain height and fell down for breaking again, and this process is repeated until materials being crushed into required size.

Variable frequency control grinding mill Is a general trend

Over the years, many factories commonly used grinding mill to grind ceramic raw materials, it generally adopts a simple industrial frequency control which is of longer grinding cycle, lower grinding efficiency, big power consumption per unit of product and big starting current, so it is bound to give the manufacturer a lot of unnecessary trouble and a serious waste of resources. With the development of society economic and expansion of production scale, the disadvantages of industrial frequency control ball mill has exposed and seriously impeded to the development of various industrial enterprises–That encourages people to develop a new machine of smooth starting, high grinding efficiency, large yield, and low energy consumption–variable frequency control ball mill.

Ceramic ball is mainly composed by gear, cylinder device, charging device, discharging device and electrical control devices.Improved equipment must have sufficient starting torque to meet the requirements of load volume, keep the motor smoothly running in the frequency operation state and ensure the motor has constant power characteristics.

Using frequency control system transform the raymond mill driving system to meet the normal low speed operation, ensure the normal process control to extend the service life of the mill and reduce maintenance.Improved equipment should achieve self-switching among automatic control founction, manual / power frequency and fault, and overcome swells caused by great inertia to guarantee the equipment normally operate.

The application of vertical mill in quartz powder processing

Quartz powder is also called silica powder. As a type of basic industrial raw material, high-quality quartz powder has wide application in glass, glass fiber, ceramics and refractory, metallurgy, construction, chemistry, casting, grinding material, electron and optical fiber industry.

It is a difficult process to process the quartz to high-quality quartz powder and the main equipment for grinding quartz in domestic market is vertical roller mill and rod mill. When Raymond mill is used, the output is about 1t/h, and the efficiency is low, the energy consumption is high and the production granularity cannot be easily controlled. In addition, the wear-resistant material that Raymond mill uses is high manganese steel which has weak magnetism, so that the mechanical iron cannot be easily removed. When using rod mill, the production indexes are no better than that of Raymond mill. With the increase of powder fineness, the iron content will also increase. How to greatly improve the grinding production capacity of quartz powder and reduce the iron content in it at the same time becomes a technical problem that must solved for the large scale production of quartz powders.

Crushing and grinding plant in angola

Angola is located in one of the top five threatened hotspots in the world with the Congolean forest which is located in the country as being endangered due to poor mining practices. Therefore Angola mining is becoming more and more severely in demanding and application. As a professional manufacturer of stone crushing plant, Oriental has always been putting increasingly demand to herself and has invented more and more crushing and griniding plants with high quality and better service which can meet clients need.

The government hopes to resume Angola mining in the southwest for crystalline quartz and ornamental marble. It has been estimated that 5,000 cubic meters of marble could be extracted annually over twenty years. To meet the demands of Angola mining, Oriental has developed more and more senior crushers and mills. Oriental has sent more techinical engineers and installation engineers for Angola mining. Besides, Oriental has already established several excellent sample customers for Angola mining. If you want to start mining in Angola and need lots of aggregate processing plant, we can offer you.

Angola was historically a major producer of diamonds, iron ore, gold and copper before independence. However, the ensuing civil war disrupted its infrastructure, significantly slowed the pace of exploitation of Angola metals and minerals base. Following the end of the 27-year conflict in 2002, the Angolan mining industry, along with economy, has grown rapidly. Angola is globally the fifth largest producer of diamonds in value, supplying 7-9% of world diamond output. As we can see that Angola is rich in diamonds and iron ore. In addition to diamonds and iron ore, Angola is also rich in several other mineral resources that had not been fully exploited by the late 1980s. These Angola minerals include manganese, copper, gold, phosphates, granite, marble, uranium, quartz, lead, zinc, wolfram, tin, fluorite, sulfur, feldspar, kaolin, mica, asphalt, gypsum, and talc.

Why are compound crushers competitive on the market?

The compound crusher is a type of high efficient fine crushing machine with the multi-functions of hammering, impacting and grinding. It is one of the most competitive machines on the market for mining machinery.The compound crusher generally works like this: materials enter the practical crusher cavity from the feeding port and then impact the high speed spinning crusher case; after the impacting process, the materials then get squeezed and crushed; then they are impacted to the inner wall of the main case and meet the hammer of the crusher; during the falling process, the materials are hit for several times and finally become the powder materials which will be ejected from the discharging port.

Our compound crusher has good reputation among customers because of its many advantages of high yield, high reduction ratio, little abrasion, low energy consumption, good leak proofing, reliable operation and simple maintenance steps.

The maintenance of ultra fine mill is in proportion to its duration

In the structure of ultrafine mill, the wear of grinding roller is very serious, but because of its working principle, the serious wear of this part will make the machine loose efficient grinding function, so we must pay attention to the dynamic wear of the grinding roller, while in the operation of the grinding machine, the wear is inevitable. But we also need to control the wear as much as possible, and the necessary maintenance of the machine also has to be done.

During the maintenance of ultrafine grinding mill, keep the equipment clean is very important, it is better to keep it in clean state, no dust, no oil and no oil spill on a daily basis. If dust is found in the production of the lubricating parts, it must be timely cleared. If dust and debris enter into the lubricating parts, it will make the equipment wear double without lubrication. The dust itself is in a minimum volume, so if the dust enters into the lubricating parts, the service life of dolomite and limestone mill will be short. Finally, we need to remind everybody is that the regular replacement of lubricating oil is also very important; we can replace the oil according to the running time of the machine, or replace the lubricating oil half a year. In some parts, it not only needs the periodic replacement of the lubricant, but also needs to regularly use the gasoline to clean the filter. However, the operator should pay attention to the tip that they must wait until the machine is completely dry after cleaning gasoline for continue to use, otherwise easy to cause production accident.

The improper maintenance of ultra fine grinding mill will make the working efficiency of the machine greatly reduce, or it may even make short-term scrap of the mill, as well as the increase of its power consumption. The increase of human labor will make the operating costs exponentially increase of investors, and they will be in the passive situation of management for a long-term period. Therefore, the correct method of maintenance is very important.
