Aggregate system is designed to improve the concrete mixture ratio at all aspects, so as to improve the quality of construction works and make them move on smoothly. High quality concrete has very rigid standards for gravels both in grain type and size. Currently, the crushing equipments mainly include jaw crusher, impact crusher, cone crusher, and hammer crusher. Which one can produce the best aggregate? Here we analyze the advantages of hydraulic cone crusher from productivity, grain type and the degree of automation.
Hydraulic cone crusher is 20% higher than impact crusher on the aspect of productivity. The most obvious feature for hydraulic cone crusher is the high grading proportion of aggregate. It combines speed and stoke crushing principle, while impact crusher is just based on the high speed rotor. Thus, the final products have a high proportion of coarse material, and 0-5mm is relatively smaller, greatly improving the proportion of qualified aggregate.
Speaking of the grain type, hydraulic cone crusher can effectively adjust the space between the chamber and materials based on the laminated crushing principle, crushing the material selectively. Reasonable designed output size, greatly improve the proportion of fine aggregate and the grain type of final products. Flakiness material only makes up a small proportion, utilizing rate improved.
As for the automation, controlling on the equipments is widely promoted with the development of mining technology. To make the maintenance easier, the designers adopt an innovative setting on the discharging port which can adjust automatically, and overload protection is added. The purpose of doing so is to prevent the material swallowed caused by the sudden shutdown. The crusher discharges automatically when it is closed down, solving the problem of artificial nesting.
Vertical Roller Mill are advanced mill equipment adopting top grinding technology applied widely in grinding non-flammable and non-explosive materials.
VSI5X crusher (the latest vertical shaft impact crusher improved from VSI crusher) is necessary crushing equipment used in manufactured sand production line.
PF impact crusher used for mining crushing with low price features a unique combination of heavy rotor design, wear material and crushing chamber.
Mobile crushers are loaded on their own crawler tracks or towed by truck horse when transported over longer distances to a new location.
Magnetic separation machine can be applied for wet dressing of ores with the size less than 3mm.
