1 Drilling machine: used to drill holes with a diameter of 20-100 mm and a depth of less than 20 meters in rocks above medium hard. According to its power can be divided into wind, internal combustion, hydraulic and electric rock drills, of which the pneumatic rock drill is the most widely used. 2 Surface drilling rigs: According to the working mechanism of the broken ore rock, it can be divided into steel rope impact rigs, downhole drilling rigs, roller rigs and rotary drilling rigs. Because of its low efficiency, steel rope impact rigs have gradually been replaced by other rigs. DTH drilling rig drives the pneumatic impactor and the drill bit together to rotate with the drill pipe. The piston impact drill bit of the pneumatic impactor is used to crush ore rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80-250 mm. The roller rig uses the rolling action of a roller cone bit to crush ore rock and is suitable for drilling 150-440 mm diameter holes in hard rock. It has the advantages of high efficiency and low labor intensity, and is used in large and medium-sized open-pit metal mines. Widely used. DTH (or cone) drilling rigs consist of impactor (or drill bit), slewing gear, lifting mechanism, pressurizing device, traveling mechanism, slagging system, drill frame and drill pipe. Rotary rigs are only suitable for drilling softer rock and coal. 3 Downhole rigs: When drilling boreholes with an aperture of less than 150 mm, 80-150 mm small-diameter submerged-hole drills can be used in addition to rock drills. When drill holes with a diameter of less than 70 mm are drilled in coal or soft rock, electric drills or pneumatic drills are generally used to drive the drill rods with a motor (or air motor), and the drilled rock (coal) passes through the drill pipe. The spiral groove discharges.
Anping Xinzheng Metal Wire Mesh Co. Ltd is able to
design and produce all kinds of metal basket products (Also named wire mesh
container, storage basket, or wire mesh cage). Those wire baskets products with

wire mesh, weaving mesh, perforated mesh and other metal mesh are been bending,
argon arc welding, spot welding and make it into various crafts. Using the
micro resistance welding and seamless butt welding technology, make the product
have no prominent spot, welding break, no flash, no loss, safe use. Grid design is beneficial to the penetration of water or
steam, and ensures the cleaning and sterilization effect. The surface of wire
mesh cage can be polished, soaked, plastic sprayed, according to customer needs
to make a variety of color crafts.
Product advantages: Disinfection basket and metal
baskets have smooth surface, no rust, corrosion resistance, non-toxic, sanitary
and environmental protection; A plurality of wire mesh containers can be
stacked and placed, and save a lot of space.
