Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad slag tunneling equipment, small water conservancy construction of diesel can be used to control the tire Pa mining machine, which has a hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions. Dunhua City, Ishikawa small reservoir of Urban Diversion Project has been designed according to the requirements of building contents are completed tunnel construction machinery, and in November 20, 1998 passed the final acceptance of the final acceptance committee concluded:. "Small shihe Urban Diversion Reservoir Engineering advanced technology, reasonable, qualified construction quality units, each part of the project acceptance of order, through nearly two years of operation and winter tests, engineering anomalies did not happen, good quality, water efficiency significantly. "diversion project built for the city to solve a great thing, but also improve our design level. Gongyi Xin Hua Cinder machine willing helping hand!巩义鑫 China Machinery Mining Knowledge Forum COLLECTION: spatial characteristics of the ore body means the ore body in three-dimensional space has features, such as ore body shape, occurrence, width, thickness, depth of burial and so on. These factors inherent in ore deposits in ways largely determine the development and utilization. Depth of burial is decided Deposits opencast or underground mining. In general the cost of open-pit mining is lower than underground mining. But this is not always the case, It depends on the specific conditions of occurrence deposits. Deposits although some shallow due to a large amount of stripping rock, its cost is not economical than underground mining, have mined using underground. Of course, some deposits in buried deep underground mining would only Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad, the choice of small water conservancy construction diesel-powered control tire Pa mining machine, which has a hydraulic walking, collecting tunnel excavation loading, belt conveyors, clear bottom, and other functions. Gongyi City Xinhua Machinery Factory is specialized in producing slag machine manufacturers tunnel, you are welcome to inquire. (3) hydraulic valve plate is easily one of the important components of the noise caused. Valve plate in use due to surface wear or unloading tank sludge deposited in open place, will make unloading tank shorter unloading position changes, resulting in trapped oil phenomenon, sparking higher noise. In the normal repair process, after grinding repaired valve plate will be shorter unloading groove consequences, then it is appropriate if not slender, will also have a greater noise. During assembly, the valve plate unloading large tank must be installed in the pump high-pressure chamber, and its angular direction of rotation of the cylinder to be relative, otherwise it will bring more noise system.
