Yes, you are right.
Single toggle crushers are cheaper as they contain less parts and usually crush faster due to higher speed & stroke. Jaw wear is usually concentrated over the bottom 1-2 feet of the fixed jaw.
jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
