Mining is the extraction of valuable geological materials from the surface ofthe earth or from underground.At its core, the demand for mining machinery and related parts is derived fromthe demand for "mine-able" natural resources. For thousands of years, minedmaterials have been shaped, processed, and used by both houshold and industries. To meet this demand, mining machinery and mining equipment are established and produced. In China,Henan Hongxing Mining Machinery Co., Ltd. is the famous company which manufactures series of mining machines. Henan Hongxing Mining Machinery Co., Ltd. is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing.The leading products in our company include: ball mill, sand-maker, jaw crusher, hammer crusher, vertical compound crusher, vibrating screen, sand maker, magnetic separator, SF flotation machine, belt conveyor, bucket elevator, spiral classifier, granulating disc, final screen, lift mixer, table concentrator, centrifugal ore separator, high-efficiency concentrator, disc feeder, pendulum type feeder and hydraulic cyclone. Moreover, we can provide program design, process flow design, standard and non-standard design for clients.In order to promote the competitive strength, our company have introduced the advanced technology from America, Germany, Japan and Australia, which established the international advanced production line, first-class modern testing base as well as research centers of sand maker, mill and mine-selecting equipment.micro powder grinding mill: http://www.china-hxjq.com/n287.html compound cone crusher: http://www.china-hxjq.com/n262.html With three-dimensional structure and land-saving ，the Raymond mill features steady and reliable transmission with screen-passing rate of 99% .The technical advantages of the Raymond Mill developed by Henan Hongxing Mining equipment Co., Ltd., the Raymond Mill with large, middle, small type energy-saving have adopted the modern design... And the Raymond Mill also have some relative names ,such as new energy-saving Raymond Mill, pendulum Raymond Mill equipment, super thin suspension grinder ,etc. And this kind of Raymond Mill can be applied to the powder manufacturing with high-pressure and closed circuit in the field of small mines,chemicals, building materials, metallurgy, etc. And the Raymond Mill has found its extensive application to crush the non-flammable and explosive materials with the Mohs of lower than 7degree and moisture of below 6% and so on. This kind of Raymond mill adopts the advanced structure and are developed on the basis of large-size Raymond mill with the advantages of high-efficiency ,low energy-consumption, small cover area, and low investment cost. And the wind classifying stream process in the circular working process of wind machine-grinding shell-and the inner circular of the wind machine. So the powder dust is little than the high-speed with the characteristics of clean peration environment and no pollution environment.
