limestone crusher machine: Introduction: limestone crusher machine are used in both primary and secondary crushing applications of aggregate, and in recycle crushing of reinforced concrete, asphalt and other construction and debris. Working Principle: When the Impact Crusher works, the motor drives the rotor rotate of the Impact Crusher with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers affect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being re-crushed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet of the Impact Crusher. Characteristics: Excellent cubic final products Special structure Non-key connection High chrome hammer Durability in long time simplicity in operation Easy adjustment, high reduction ration Good performance and high reliability Technical Parameter: Models Rotor size (mm)Feed opening (mm)Max. feed size (mm)Capacity (t/h)Power (kW)Weight (t)PF1007Φ1000×700400×73030015-30375.54PF1010Φ1000×1050400×108035050-805515PF1210Φ1250×1050400×108035070-1309515.25PF1214Φ1250×1400400×143035090-18013219PF1315Φ1320×1500860×1520500120-25020024PF1320Φ1320×2000860×2030500160-35026027 Note: This series crusher fits in the hard stone crushing, and the 90% of the output materials size ≤ 40mm
