Compression-style crushers are typically used with more abrasive and harder materials such as granite and come in either cone crusher or jaw crusher varieties.These types of machines reduce materials by squeezing them until they break.Many times, impact crushers simply do not have enough power to crush these types of materials.If the initial compression crushing does not reduce the materials to the consistency necessary for the clients needs, an impact crusher may be used as a secondary crushing method.
In the concentrator, the hardness of the ore is 8 ~ 10, the grinding power index is 14 ~ 15 kwh/t, the moisture content is 3%, and the loose density is 1.69t/m 3, density 2.7tm3.The rock crushing system is mainly equipped with a vibrating feeder, 16 sets of conveyor belts, and 6 sets of heavy-duty double-deck vibrating screens (pre-screening, heavy screening), 17 single-layer vibrating screens (check and screen, single screen), 4 medium crushing simons cone crushers and 8 fine crushing simons cone crushers.
Phosphorus (p) lower than 200 ppm (phosphorus is the ep or extreme pressure additive required in many crushers).When this phosphorus level decreases it indicates that the oil no longer has the load-bearing characteristics needed to protect your crusher bearings.Verify you are sourcing an ep gear oil with your oil supplier.Silica levels above 150 ppm indicate a potential dirt entry source, verify the breathers are good and that all tank seals are intact.Water should be 0 ppm so higher levels may indicate condensation issues maybe a result of breather issues or reservoir or crusher seals might be permitting that water entry.Be sure to sample each bearing location so that you can identify the potential source of the contamination whether it be organic or external.
Experience from hp development and thousands of customer applications around the world have played an integral part in metso innovations, including the mx multi-action range.To date, hp maintains its position as the market leader in cone crushers as a crusher that simply delivers.Similarly, to its symons and omnicone predecessors, this crusher has a proven track record in the aggregate and mining industries.Simply put, the hp series cone crushers continue to fast track the industry standard with new technology and features, proven performance and reliable output.Thirty years young and still going strong.
Transformation of closed raw mill can still achieve a higher yield in the raw material into the mill when the water up to 3.5%, a 2.2 * 7m transformation of the cost of raw mill at the end of a few thousand dollars can, mill transformation time is generally not more than 24 hours, the same conditions, to step down production can be increased by about 20 to 80 percent.Second, the crushing jaw crusher modification technologies.
Hammer stone crusher is the main working parts with a hammer (also known as hammer) of the rotor.Rotor from the spindle, disk, composed of pin and hammer.Cavity in the broken rotor motor driven high-speed rotation.Material from the upper mouth to feed into the machine, by the high velocity hammer blow, impact, shear, abrasive and grinding.The lower part of the rotor, with sieve plate, crushing the material in grain size smaller than mesh size sieve discharged through the larger than coarse mesh size in the sieve retention continue to be a hammer blow on and grinding, and finally through the sieve plate from the plane.
