PF Impact Crusher

Impact Crusher is a common crushing equipment, many manufacturers are in the making. Impact Crusher crushing cavity number can be divided by two cavities and three cavities, according to the number of rollers can be divided into two kinds of single rotor and double rotor. Currently single rotor impact crusher is widely recognized crushing equipment.

The Future Direction Of Impact Crusher

Crusher though often used, but mostly for the production of building stone (because of greater demand of stone), but also some soft rock. Advantages crusher is good grain type, capable of producing high-quality stone, flakiness content is extremely low. Limitations of the use of impact crusher, hard rock crushing loss when large, use is not wide enough.

With the development of manufacturing technology, some of the hydraulic clearance systems, rare lubrication system, electromechanical control system has also been introduced to us crusher equipment industry, which shows that the crusher towards green energy, easy to maintain direction, plus resistance grinding material is also increasingly progress, creating a future expansion of the crusher range of potential applications.

At present, foreign investment in such equipment for a large, and our impact crusher is still some way to go, it is currently in the preliminary mechatronics equipment, more companies just introduced a hydraulic cover-clearance, rare lubrication easy to imitate part, and for the truly mechatronic put little value on the intelligent control there is a certain gap with developed countries. But if China's crushing equipment to achieve this level, it will take a high-end line, there can be a low price now.countries. But if China's crushing equipment to achieve this level, it will take a high-end line, there can be a low price now.

Focus on the future development of the crusher is controlled electromechanical integration, such control might be possible to be more precise, the benefits we derive more than just convenient operation, lower labor costs, higher productivity is important that each node energy control You can be aware of.

The Usage Of Impact Crusher

Natural resource depletion and limit gravel mining in the background, will become the main mechanism gravel material construction engineering field, but as part of the mechanism sand production in the needle, too much powder content, grain shape gradation unreasonable noise, dust pollution and high energy consumption and other issues, to some extent, restricted the mechanism to promote the application of gravel, machinery and equipment manufacturers therefore it is necessary to provide users with more energy-efficient crushing equipment, and promote the healthy development of the construction industry.

The device is up to 350 MPa compressive strength, it is particularly suitable for equipment manufactured stone pavement, it has been widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry, etc., for limestone, feldspar, calcite , barite, fluorite, rare earth, kaolin, coke, coal, gypsum and other materials ore crushing operations.

For a long time, coal is China's industrial development one of the main energy in China's primary energy consumption accounts for more than 70%. At present, China's proven coal reserves of 114.5 billion tons, accounting for more than 90% of the fossil fuels. It is known that plants in the death, until the accumulation of coal into the process, in addition to the formation of coal, with the addition of other components, will form other coal juxtaposition of resources. For example, coal-bearing rock series in a large number of coal occurrence genetically related metal and non-metallic minerals such as bauxite, refractory clay, siderite, hematite, pyrite, manganese, phosphate and the like. Again, the occurrence of a large number of combustible organic minerals, such as oil shale, stone and coal. Accompanied by a large number of coal resources exploitation, domestic coal total reserves dropped continuously, these genetically related with coal combustible organic mineral resources should be taken seriously, you can gradually make up for the problems caused by coal reduction.

A Case Study of oil shale. Oil shale is an important associated mineral coal refers to form of industrial significance of oil in shallow rock pyrolysis, including shale, marl, carbonate rocks and other debris. Oil shale is formed in a certain depth of the water environment, rich in terrestrial higher plant debris, and rich underwater flora and plankton as low diagenetic substances. The coal is usually terrestrial higher plants as diagenetic material, so the oil shale into oil capacity is often greater than the capacity of coal to oil. Portrait horizon, the oil shale is usually located above the coal seam. Chunks of oil shale crushing, screening, to a great oven; heating in the absence of air conditions, so that the organic matter decomposition of oil and gas; oil and gas re-entering a cooling device is cooled condensed into an oily liquid, which is shale oil. Shale oil can be used as fuel for power generation, heating and transportation.

From mined oil shale to be used as fuel oil shale crusher needs to participate. European version of the back-breaking is broken specialist GM crushing plant to build the latest generation of international top quality. Compared with ordinary back-breaking, back-breaking increase in the European version of the open-top and the hydraulic adjustment device, reducing downtime and repair time; the rotor design, exclusively developed rugged heavy-duty rotor, achieve higher moment of inertia, in favor of increase crushing capacity; the whole cast steel housings, and the rack fit perfectly, greatly enhancing the radial strength of the bearing housing; a unique wave-like back plate and plate hammer curved design, making performance to the next level .

Wear Reason Of Impact Crusher Parts

Impact crusher is the common crushing machine. The wear parts are the most important parts for crushing the materials. But they are also the most serious to be worn. If we know the wear reasons of impact crusher parts, we can reduce or avoid the wear. So today, I will make a detailed introduction about the wear reasons. Hope it will help you.

The hammer is the key part for impact crusher. It is related with the service life of impact crusher. So what about the wear reasons of the hammer? First, the material is improper. The wear resistance of the hammer is related with the hardness and toughness of materials. It needs the hardness and toughness to cooperate with each other. At present, the high manganese steel is the commonly used materials for the hammer. If the hammer grinding surface has not been enough stress, it must have not the high wear resistance.

Second, the actual working conditions will affect the hammer wear. If the hammer is not formed effective work in the hardened layer, hardness properties of the hammer is not up to the required standard normal work. So the hammer is not wear-resisting, life is greatly lower than life expectancy during design. Third, hammer directly contact with the materials. In the crushing operation, only a few materials can block into the combat zone. While most of the materials, especially the bulk materials, only the end of the strike zone, thus causing material and the hammer head sliding friction. And back bonding powder on the board will make the friction is more serious, which caused the rapid wear.

In addition, the operation is also important for the hammer service life. If the crushing material is too big, and excess the specified size, it will wear the hammer and the impact plate. Except for the hammer, the impact plate is also another vital crushing part. The influence factors of hammer are also the same with the impact crusher. So in the production, we should pay attention to the above factors. They all are the wear reasons of impact crusher wearing parts.
