According to the data of global sandstone aggregate, artificial sand has unlimited development space and broad investment prospects, which can bring huge benefits to investors.
Castings are produced by pouring liquid metal into a mold cavity. For a casting to be successful, the mold cavity must retain its shape until the metal has cooled and fully solidified. Pure sand breaks apart easily, but molding sand contains bonding material that increases its ability to resist heat and hold shape.

McLanahan crushing equipment accepts feeds of large material and reduces the material to the desired product size. Because each crusher type has a limited reduction capability, sometimes several stages of crushing are needed to achieve the desired final product size. Primary crushers are important for kicking off production and initial product sizing for further processing. They receive the material directly from the blasting, drilling or dredging process. Secondary and tertiary crushers are utilized for additional refinement of the material.
Motor drives belt and belt pulley, makes moving jaw up and down through eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. During this process, the material is crushed and ground, thus the crushing will be done. When the moving jaw is down, the angle between lining plate and moving jaw becomes small, the moving jaw plate will leave the fixed jaw plate on account of the effect of pulling bar and spring, and then the crushed material will be discharged from the lower opening of the crushing room. With the motor continuously rotating and the material periodically crushed and discharged by the crusher, the mass production can be realized.
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate. When the mined gravel is fed into the washplant. It is classified by particle size using various stationary or vibrating screens. Classifying gravels provides for more efficient gold recovery, reduced water consumption, and facilitation of mine site rehabilitation, and is practiced by most operators. The oversize material, usually larger than two inches, slides out of the washplant into a pile where it can be moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluicebox where the gold and heavy black sands are concentrated. Tailings are gravel, sand, and other materials accumulated at the end of the sluicebox. Tailings are routinely moved away from the sluicebox by a loader or bulldozer.
Quartz sand is made by crushing quartz sotnes into sand with sand making machine. In this quartz sand making plant, our quartz rock crusher machine ,the jaw crusher is used as primary crushing equipment, impact crusher is used for fine crushing, then sand making machine is used for making sand and stone shapping. Quartz Vibratory Screen is used as screening machine to screen out the suitable sand.
The hammer crusher machine completes the crushing material operation by the impact energy. During the operation of hammer crusher machine, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The high-speed rotary hammer impacts, shears and tear the material, all the materials are broken. At the same time, the gravity of the material itself make the material from the high-speed rotating hammer head rushes toward the baffle and the screen strip in the frame body. The material larger than the size of the mesh hole is retained on the sieve plate, they are struck and ground by the hammer until it is broken to the required discharge particle size. Finally, the materials discharged through the sieve plate.

K Mobile Crushers own 7 series and 72 machine models, and fully covers various production demands for coarse crushing, intermediate fine crushing, fine crushing, shaping, screening and sand washing. Customer can choose independent operation and combination operation like three-combination, and four-combination, etc.; compared with the other mobile crushers and screens in domestic and foreign markets, this series has more machine types and wider coverage.
Primary Lokotrack plant feeds the material to the lifting conveyor of Lokotrack LT330D, which transports the material to the screen. The oversize material is taken to the cone crusher and the screened material is divided to the product conveyors. After the material is crushed, the revolutionary centrifugal lifting conveyor returns it back to the screen in closed circuit.
With their large feed openings, heavy duty aprons and rugged rotors, the 1313 series crushers are designed to handle big feed sizes and high capacity crushing.
Rotary dyer is mainly used for drying materials with certain humidity in ore dressing, building materials, metallurgy, chemical industry, printing and other industries.
