Jaw Crusher Sizes and Power Ratings. Size is specified in terms of the gape and width, typically listed as gape x width. Largest jaw crusher is 1600 x 2514 mm with motor ratings of 250-300 kW. Metso crushers C200 series are 1600 x 2514 mm with motors rated at 400 kW.
The primary operating costs of a crusher are parts and labour for maintenance, which can vary approximately twice as much as the power for the motor. Gyratory crushers generally cost less than 1500 per hour to run, while Jaw crushers cost less than 200, including electricity Infomine, 2008.
Mar 04, 2006 The sum of resistances tractive pull. The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5 Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.
Jul 15, 2019 The quality of the rewind has a big impact on operating cost. A poorly rewound motor may lose up to 3 in efficiency. A 100 HP motor may use several hundred dollars more in electricity each year due to this drop in efficiency, compared to its original efficiency. The operating cost may be even more compared to a new high efficiency motor ...
