Jaw Crusher Machine

The jaw crusher machine is widely applied in the primary crushing of large rocks and stones. It can be used in cement plants, quarries, stone materials plants, coal processing plants, highway construction, road and bridge aggregates, concrete mixing plants, steel mills, water conservancy projects, construction waste recycling, and other industries. A jaw crusher is the earliest crushing equipment that had been invented and is the most sturdy crusher for sale.

In an AAC block plant, a jaw crusher is used for crushing lime to smaller sizes. The lime will be ground into lime powders in ball mills. Then it can be mixed with other raw materials for making the slurry.

Highlights of CNBM jaw crusher machine

Wide range of capacities

The capacity of the jaw crusher is 50-1275t/h. The feeding size is 425-1050mm.

Easy operation & maintenance

The discharge port adopts a hydraulic design which is convenient for adjusting. The dual-chock discharge opening system is simpler, safer, and faster than the old-fashioned adjustments. It will only take a few minutes to finish the adjustment of the outlet. This system is especially effective when the system needs to be cleaned due to a power outage that causes the system to shut down with the load.

The jaw crusher host is easy to install, easy to overhaul, and has high strength. The shock-absorbing device and the limit block absorb the shock energy and allow the crusher to move slightly vertically and longitudinally, thereby reducing the impact on the foundation.

Reasonable structure & stable operation

A modular, non-welded frame structure is adopted. The two rolled steel side panels are firmly bolted together through precision-machined pins and high-quality cast steel frames, making the equipment more durable. In addition, the mobile jaw assembly of the jaw crusher is made of high-quality steel castings and rotates through two large cast steel or cast iron flywheels.

The grease-filled labyrinth seal protection structure of the jaw crusher prevents the lubricating grease of the bearing from being polluted.

An automatic lubricating system ensures the stable operation of moving parts such as bearings.

The jaw plate locking mechanism enables the jaw plate to be installed in place quickly, accurately, and firmly.

High-quality wear parts & a long lifespan

Key parts of the jaw crusher machine are imported from an internationally famous brand.

The thickness of the jaw plate is optimized and high wear-resistant manganese steel alloy material greatly prolongs the life of the wear parts.

CNBM jaw crushers can adapt to the crushing requirements of different materials by replacing different types of jaw plates. The movable jaw is the same as the fixed jaw liner, which can be used interchangeably.

Working principle of jaw crusher machine

The jaw crusher structure mainly includes a frame, working mechanism, transmission mechanism, adjusting device, tensioning device, safety device, and lubrication system.

jaw crusher working principle

When the jaw crusher is working, the motor drives the belt and the pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw closer to the fixed jaw. The crushed material is crushed by multiple forces such as extrusion, rubbing, and grinding. When the movable jaw moves down, the angle between the toggle plate and the movable jaw becomes smaller, and the distance between the movable jaw plate and the fixed jaw plate increases under the action of the pull rod and spring, and the crushed material is discharged from the discharge port of the crushing chamber. With the continuous operation of the eccentric shaft, the movable jaw reciprocates periodically, and the materials entering the crushing cavity are continuously crushed and discharged, realizing continuous production.
