The Enormous Distinction of the Different Jaw Crushers

Such crusher adopts crank double linkage mechanism; moving jaw undertakes large reaction force, but its eccentric shaft and connecting rod only undertakes small uneven force, so the industry makes it into more mainframe and mid-sized machine to break hard material. In addition, when this crusher working, the trajectory of each point is an arc at the center of mandrel, arc radius is equal to the distance of the point to the axis; the upper end arc is small, the lower end of the arc is large, crushing efficiency is low, its crushing ratio is generally 3-6 times of simple trajectory, so it is called swing jaw crusher.
The jaw crusher can be divided into simple pendulum jaw crusher and compound pendulum jaw crusher. In order to drive the jaw crusher well, it is necessary to better understand it. Now, let’s briefly introduce the difference between two jaw crushers.
Working principle of compound pendulum jaw crusher: The jaw upper end of the compound pendulum jaw crusher hanging in the eccentric shaft directly, as the crank linkage rod is driven directly by the eccentric shaft eccentric, the lower end of the movable jaw hinge attaches to the thrust and supported on the rear wall of the rack. When the eccentric shaft is rotated, the trajectory of each point on the movable jaw is equal to the eccentricity by the suspension point of the circumferential line (the radius), gradually becomes oval downward. This mechanical action on the point of the jaw trajectory is more complex, so called complex pendulum jaw crusher.
Working principle of simple pendulum jaw crusher: moving jaw hangs in mandrel, can be used to swing around. When the eccentric shaft rotates, the rod does reciprocating up and down movements, which drives two thrust plate do reciprocating motion, thus promoting the moving jaw to do around reciprocating and achieve breaking and unloading. It is characterized by a smaller moving jaw vertical displacement, less excessive broken phenomenon, smaller wear a; simple and compact structure, small force of eccentric shaft transmission parts.As the professional manufacturer of complete sets of mining machinery, such as sand washing plant, cement making plant, Henan Hongxing is always doing the best in products and service.
