The crushing operation is often divided into coarse crushing, medium crushing, and fine crushing according to the particle size of the feeding and discharging materials. The commonly used sand and gravel equipment includes jaw crushers, impact crushers, composite crushers, single stage hammer crushers, vertical crushers, rotary crushers, cone crushers, roller crushers, double roller crushers, two in one crushers, and one-time forming crushers.

Mining machinery is the mechanical equipment used for direct mining of useful minerals and preparation work, including: mining machinery for metallic and non-metallic ores; Coal mining machinery used for coal mining; Petroleum drilling and production machinery used for oil extraction. The first pneumatic disc shearer was designed by British engineer Walker and was successfully manufactured around 1868. In the 1880s, hundreds of oil wells in the United States were successfully drilled using steam powered impact drills. In 1907, a rotary drill was used to drill oil and natural gas wells, and since 1937, it has been used for open-pit mining drilling. With the advancement of technology, new types of hydraulic fracturing technology are gradually being introduced to the market. Hydraulic fracturing, also known as hydraulic fracturing, is a new technology for non explosive fragmentation of rock masses, rock blocks, and concrete structures. It is an engineering equipment that uses high-pressure water to fill a tubular sealed elastic expansion device inserted into a borehole, and the enormous expansion force generated by pressure energy to separate or disintegrate rock blocks from the rock mass.

① Rock drill: used to drill holes with a diameter of 20-100 millimeters and a depth of less than 20 meters in rocks of medium to hard or above. According to their different power, they can be divided into pneumatic, internal combustion, hydraulic, and electric rock drills, with pneumatic rock drills being the most widely used. ② Open pit drilling rig: According to the different working mechanisms for crushing ore and rock, it is divided into steel rope impact drilling rig, down-hole drilling rig, rotary drilling rig, and rotary drilling rig. Steel rope impact drills have gradually been replaced by other drills due to their low efficiency. ③ Underground drilling rig: When drilling underground blast holes with a diameter less than 150mm, in addition to using a rock drill, small diameter down-the-hole drills with a diameter of 80-150mm can also be used.
