SANDVIK JAW CRUSHER SERIES

The Sandvik jaw crusher above is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.

Jaw crushers are made with jaw widths varying from about 100 mm to 200 mm and the running speed is about 240 rpm, the smaller machines running at higher speeds. The speed of operation should not be so high that a large quantity of fines is produced as a result of material being repeatedly crushed because it cannot escape sufficiently quickly.

For a 50-Hz system, the formula would be: 50 x 60 x 2 = 6,000 no-load rpm ÷ number of poles. Using this formula, you can see that a four-pole motor operating on the bench under no-load conditions runs at 1,800 rpm (7,200 ÷ 4 poles). Note that when an ac motor is loaded, the spinning magnetic field in the stator does not change speed.

Tips for maintaining efficiency in crushing circuits

Jaw crushers. A jaw crusher is a compression-type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The setting or the space between those two pieces of steel controls the discharge size. The tighter the setting, the smaller the output size and the lower the throughput capacity.

How to Calculate the RPM of a Motor

For a 60 Hz system with four poles, the calculations to determine RPM would be: (Hz x 60 x 2) / number of poles = no-load RPM. (60 x 60 x 2) / 4. 7,200 / 4 = 1,800 RPM. The amount of slip varies slightly based on the motor’s design. A reasonable full-load speed for a 60 Hz, four-pole motor would be 1,725 RPM.
