Xingaonai - Model PEV Series -Jaw Crusher
The PEV series jaw crusher is a new-generation crushing equipment developed through comprehensive optimization of motion parameters, structural design, and adjustment mechanisms based on traditional jaw crushers. It is suitable for primary and secondary crushing of various soft, medium, and hard ores with a compressive strength of up to 280 MPa, and is widely used in mining and related industries.
PEV系列颚式破碎机具有产量高、能耗低、结构坚固、操作维护简便等优点，符合环境影响评价标准，是各种岩石物料粗破碎的理想选择。
Strong and stable structure
The side wall and front and rear walls are separated, and the welding frame is replaced by bolting. It is a detachable and non-welding structure.
Large crushing ratio
The optimization of the motion parameters can ensure that the stone can start crushing at the upper part of the crushing chamber, so that the stroke at the lower part is larger, and the crushing ratio is improved. The strong power and reasonable equipment speed ensure that the equipment can crush hard materials. Stability and high efficiency Operation.
Rational design
Symmetrical "V" shaped crushing cavity, large toggle angle, large stroke, reasonable speed, so that the feed particle size is larger, the output is higher, the particle size is more uniform, the wear of the jaw plate is lower, and the shock-absorbing installation design; the movable jaw guard plate design ; Oversized bearing design.
Durable
The detachable structure is more convenient for transportation and installation, and the damaged main parts can be replaced directly, which will greatly improve the life of the equipment and save more cost for customers.
The crushing method of the jaw crusher is a curved extrusion type, and its working principle is to simulate the jaw movement of animals. When working, the motor drives the belt and pulley through the eccentric shaft to move the movable jaw up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, so that the movable jaw is pushed close to the fixed jaw, and the materials are crushed many times through the extrusion, friction and grinding between the two jaws. When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the pull rod and the spring, and the crushed material is discharged freely through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the motor, the movable jaw periodically crushes and discharges materials to achieve mass production.
