Longzhong explain daily maintenance and operation forcustomers. Beforecrusher (impact crusher) run, must conduct a comprehensive inspection. During the inspection, themain switch must pull down circuit. Inspection items are as follows: all thefitting must be tight, cannot have loose phenomenon; Ore crushing cavity cannothave, and any other items; Check the width of the row ore mouth; Check andprocess equipment interlocks between up and down. In addition, also check theamount of oil in the tank and the oil temperature. Cold season when the oiltemperature is too low, heater heating should be used. Check lubricationequipment, oil pump motor interlocks and crusher motor is normal.

After check that preparation of qualified, closes the circuit switch,can according to the following procedure:

First start the lubricating oil pump motor, and checking andadjusting oil pressure. The oil pressure should be in o.08- o. 15 Mpa range.Check filter switch drive too is correct. According to the flow indicator andpressure gauge and so on, and check all lubrication system work. When the oilreaches all lubricating points, according to the provisions of signal drive,start the crusher. Crusher idling 3-5min machine up tospeed, then switch to the mining machine crusher crushing work.

Crusher broken into normal after work, the operator must abide by andpay attention to the following matters:

Check the operation condition of crusher, there should beno abnormal internal quite a blow. If there is any abnormal sound and all theabnormal situations, should be dealt with immediately. Special circumstancesshould immediately stop operation. Feed particle size no greater than the feedmouth of o. eight times, ore bog groove and the crushing cone bottom should notbe ore block, will otherwise ore crushing cone is raised, slag entered into theeccentric shaft sleeve, cause an accident. In pump operation, often check alloil flow indicator, oil temperature and oil pressure on the number ofinstructions.

Crusher parking is the correct order:

First stop the feed crusher, wait for after all ore crushing cavitydrainage, can stop the crusher, and then stop the conveyor.

With the sustainable development of China's economy, inindustrial coal pulverizing, gypsum powder processing industry occupies a largeproportion. Gypsum powderis one of the five big gel material, occupies an important position in nationaleconomy, is widely used in construction, building materials, industrial moldsand art model, chemical industry and agriculture, food processing and medicalhairdressing, and many other application areas, is a kind of importantindustrial raw materials.

Gypsum powder production line process can be summarized as: gypsumore vibrating feeder, jaw crusher, bucket elevator, mill raw materialwarehouse, storage of finished goods. The grinding process is particularlycritical. Luoyang Longzhong Raymond mill is in thedomestic and foreign similar products of advanced structure, and on the basisof the Raymond mill industry update design improvements, especially suitablefor gypsum powder production. The device than ordinary mill with high efficiency, low powerconsumption, cover an area of an area small, one-time investment is small.For high pressure suspension mill , the roller under theaction of centrifugal force, rolling on the grinding ring tightly, so when thegrinding roller and grinding ring and to a certain thickness does not affectthe finished product yield and fineness.

Luoyang Longzhong,moreover, after a long period of research and innovation, the mill will beconstantly updated, there are many successful launch LSM Ultra-fine mill,Raymond mill, ball mill, powder mill not only finished product granularityadjusted within the range 802500 mesh, more can satisfy all currently on themarket for gypsum powder fineness requirements, customer satisfaction isassured of gypsum powder processing equipment.

Green mining equipment is the direction of the futuredevelopment of mining machinery, including high efficiency, energy saving, highquality crushing, screening, transportation equipment become manufacturer ofmining machinery research and development production priority.

General miningmachinery equipment (such as impact crusher, jawcrusher, wet coal crusher and hammer crusher) normal life for 20 ~ 30 years, large amounts of overterm service of complete sets of equipment will also be gradually entered astage of scrap. According to the traditional mining machinery design andmanufacturing philosophy, after the mining equipment scrap, will become a pileof scrap iron and trash, the recycling of scrap products, metal parts mainlyadopts recycled smelting method, the product is a "from cradle tograve". The process of recycling and remanufacturing utilization rate isvery low, and waste mining machinery products and pollution is serious, ifwaste mine mechanical and electrical products is not renewable resourceseffectively in time, will become society especially mine pollution.

Mining machinery (sand extraction system) is a large pollutionresource. Facing the increasingly serious resource and environmentalconstraints, closely surrounding the 4R in whole life cycle of product designand management is to reduce energy consumption, pollution, an important meansof implementing sustainable development strategy. Enhance the structuralsafety, reduce the quality, reducing energy consumption, improves the purpose ofthe performance major mining machinery products online monitoring direction inthe future.

In future development, Luoyang Longzhong heavy industry will developthe new type of high efficiency and energy saving, environmental protection andresource recycling technology and equipment, development of new energy, miningmachinery, promote the competitiveness of the enterprise products are recognizedby the market!

We produced sand making equipment including sandextraction system, sand maker, screw sand washing machine, wheel sand washing machineand artificial sand production line etc,.

 Crusher can be linked with many industries,such as, the development of steel industry, mining, construction, etc. Crusherand sand making machine has a long history of development and after a longpractice, jaw crusher
, verticalshaft impact crusher
, cone crusher
, impact and soon are produced conforming with the long-term practice.

 Machinery industry was still in down times,1980 s, when economic development was in a relatively stable state and wascatching up with China’s steady economic development. In general, thedevelopment of mechanical industry is cyclical, which is generally not morethan ten years. This development cycle is constant, and also won't be changed.Because every industry has its own stage of development cycle. Crusherindustry's development is closely related to the economic chain.

China's economic developmenthas begun gradually a momentum of rapid development since the 80s. No matter inwhat industry, including China's railway construction, highway construction,real estate development, mining, and water conservancy industry are in rapiddevelopment. At the same time, the development of the industry has led to aneconomic industrial chain, for example, a highway need to use the cement,gravel, sand, etc., which makes the mining, sand and gravel industry usher apeak. With the rapid development of the mining and sand production，the crushing machinery industry’s development gradually enters thepeak. And the development of the industry hastens the development of steelindustry again. From all of these examples, we can see the development of everyindustry is closely related to the industrial chain.
