Tucked away in the northeastern section of Beijing just outside the Fourth Ring Road stands what was once the pinnacle of Chinese industry. The scale of China's manufacturing capacity and its domestic market for machinery are remaking the industry's international landscape. China's dynamism presents opportunities for foreign machinery makers as an export and investment destination, as well as an up-and-coming source of capital. ore milling equipment is the machines directly used for the mineral mining and ore milling equipment, including ore milling equipment and mineral processing machinery. Broadly speaking, exploration machinery also belongs to ore milling equipment category. In addition, many other equipment like cranes, conveyors, fans and drainage machinery are also applied in mining operations. Mining machines are the equipment used for the exploitation of valuable minerals including digging machinery for the mining of metal ores and non-metallic minerals, coal ore milling equipment for the mining of coal, oil drilling machinery for the exploitation of oil, etc. The first wind moving wafer shearer was designed by a British engineer named Walker, and was successfully manufactured in about 1868. ore milling equipment is the process of choosing valuable minerals from the collected raw materials according to their differences in the physical properties, physicochemical properties and chemical properties. The machinery that implemented this choosing process is called ore milling equipment machinery. ore milling equipment machinery can be divided into crushing, grinding, ore milling equipment, sorting and dehydration machines. The commonly used crushing machines are jaw crushers, gyratory crushers, cone crushers, roll crushers and ore milling equipments and so on. Drum mill is one of the commonly used grinding machines including rod mill, ball mill, pebble mill, etc. Hydraulic and mechanical grading machines are widely used in wet classification work.
