At present portable jaw crusher , the majority of imitation, less developed, started earlier but do not develop fast, the product manufacturers alike. Although with the price advantage in the market sales volume occupies the advantage in technology, but the quality and the gap compared with foreign advanced level: the impact crusher wearing parts life in general than the foreign advanced products is low.
There is a gap between the impact crusher with large foreign impact crusher . The 3, 4 paragraph impact crusher to 2 stage impact crusher direction, and close to the impact crusher and impact crusher .
In order to narrow the gap between the impact crusher technical level, should take the following measures: because the impact crusher is used in bad conditions, therefore is the key, and the service life of wearing parts so, machining process to the introduction of special material, can not stay in high chromium cast iron, the conventional high rock steel levels, such as hard alloy inlay, composite casting, ceramics etc..

Due to the local quartz stone high grade, the market demand, stimulated a large number of quartz stone through the processing of wealthy private investors According to the relevant departments, only Fengyang County, there are more than 480 quartz sand processing enterprises, which will drive the development of ultrafine mill.
Quartz stone is an important industrial mineral raw materials, the mill after the final grinding can reach 20 mesh, 40 mesh, 80 mesh, 120 mesh, 325 mesh, 1000 mesh, or even higher fineness, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical, plastics, rubber, abrasive and other industrial production. In view of the rapid development of the application of vertical roller mill in recent years, the production of quartz sand has attracted the attention of the society and has become the industry which has been favored by investors in recent years.
Quartz stone processing production process in the crusher, sand making machine, quartz stone milling equipment selection is essential, high-quality crushing equipment, safe operation practices, stable working conditions, not only can improve the quality of quartz sand finished product grade, But also to a greater extent to ensure that the production process of clean and environmentally friendly, with long-term economic and social benefits. If the use of poor quality of the indigenous model of production, can only bring more production processes and the late production of insecurity.

The 'fail-to-commissioning' of the pulverizer means that the stainless steel bearing of the boiler pulverizer maintains a stable state at a high temperature of over 60 ° C and does not cause a bearing due to the rapid temperature of the bearing temperature and the outlet oil temperature Where the vibration intensifies and then melt, there is the operation of the mill in the 'tile' phenomenon. So customers want to choose a 'trial delivery of the tile,' the ore milling equipment, ore milling equipment manufacturers in the production of the machine put all the factors into the scope of consideration.
In addition, the fineness of pulverized coal grinding is also related to the quality of power plant combustion. Therefore, the choice of ore milling equipment manufacturers should also take full account of word of mouth and industry production problems. Pulverized coal in the grinding machine to complete the work of grinding, the machine will be hot air blown into the boiler for full combustion, and coal combustion in the boiler will produce hot flue gas, these hot flue gas will flow around the boiler around the heat, And then follow-up separation of coal ash. Thermal power plant with medium-speed pulverizer for pulverized coal pulverized coal powder fineness and grinding efficiency has a very good protection, the fineness of the coal so much easier to burn in the boiler, can improve the use of coal Rate, reduce the possibility of environmental pollution.

Coal is the main power plant in the domestic power generation base material, medium-speed ore milling equipment grinding briquettes crushing, effectively improve the thermal power plant's coal-fired efficiency. In the ore milling equipment classification, according to the coal parts of high and low speed, put the power plant boiler mill into three different types, medium-speed mill which will become a thermal power plant to choose a more.
Thermal power plant pulverizer is an important guarantee for the full combustion of pulverized coal in power generation. The common type of ore milling equipment is divided into flat type grinding, bowl grinding, E type grinding and roller grinding, Boiler pulverizer due to small footprint and lightweight structure and low energy consumption, get more widely used.
The working principle of the ore milling equipment is that the raw coal in the coal bucket should be sent to the pulverizer and then pulverized into the pulverizer, and then the pulverized coal is blown into the exhaust fan by the hot air and then into the furnace Internal combustion. In the speed of ore milling equipment selection speed is generally 40 ~ 300r / min or so, the working principle is relatively suitable for grinding the nature of soft coal material.

Ore milling equipment in accordance with the high and low speed of coal parts, put the power plant boiler mill into three high school low three different working speed of the type of small ore milling equipment which will become a thermal power plant more choice. Small coal pulverizer is a key equipment for the preparation of coal-water slurry in large-scale thermal power plant. The coal-fired ore milling equipment can crush the briquettes and improve the coal-fired efficiency of large-scale thermal power plants.
Power plant medium speed pulverizer is an important guarantee for the full combustion of pulverized coal in power generation, so the small ore milling equipment is particularly critical in the process of crushing briquettes. General coal-water slurry preparation method is divided into dry and wet, dry wet method is the biggest difference in the process of kneading pulverized coal water quality and proportion.
Coal-water slurry mill operation process is the production line of workers will be placed in the coal into the coal bucket, the equipment will be coal in the coal through the conveyor belt into the coal slurry pulverizer for the first round of the impact of broken, And then through the separator to meet the requirements of the pulverized coal into a specific component and high concentration of grinding for chemical action, and finally the completion of the chemical effect of the pulverized coal sent into the separator slurry coal slurry.

Because of the excellent performance of the machine can be processed with hardness less than 6.5 humidity below 6%, a variety of minerals, such as barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, bentonite, kaolin, cement, phosphate rock etc..
The fineness of the material can be adjusted between 325-2000 meshes. In the ordinary ultra-fine iron ore grinding and grinding production line, the configuration of a high-performance ultrafine mill can be a multiplier effect.
Our country mill manufacture profession market is very broad, including chemical industry, mine, construction, water conservancy, metallurgy, coal mine, glass and so on each profession. In China, the most important areas of application are cement industry, paving and mining. The grinding machines used in these two industries account for about 30% of the industry. In the crusher industry as a whole to improve the situation, ultra-fine crusher has also been a good optimization and upgrading, on the one hand better energy-saving, improve grinding efficiency. On the other hand, the discharge fineness is more accurate, more uniform and finer.

As everyone knows, there are many different powerful crushing machinery manufacturers on the construction waste crusher market, at present the crusher form very much, according to the main force of the crushed material can be divided roughly for extrusion, impact type, shear type crushing machine, extrusion type crusher mainly include jaw crusher, crusher, cone crusher, smooth or the groove type of tooth surface of roll crusher and so on, how to choose in the all kinds of equipment in a suitable for your own is very important.
The first point is very important for coal crushing is used frequently in construction wate crusher, coal operators can reduce the scope of the choice suits own construction wate crusher. How can ability in numerous hammer stone crushing and choose the most suitable for their own machine producers? We must first consider the quality of the equipment, followed by construction waste crusher price and the corresponding after-sales service.
