Jaw Crusher

What is Jaw Crusher?

Crushers play a fundamental part in the stone crushing process, among which Jaw Crusher is mostly used. Jaw crusher is the firstborn crushing machine that processes materials by adopting the principle of mutual extrusion between jaw plates. With simple structure, reliable performance, and easy maintenance, the jaw crusher machine is widely used in the first process to crush all kinds of rocks with less than 320MPa compressive strength into medium particle size for one time.

Fote jaw crusher is always used with cone crusher, impact crusher and sand maker to constitute the sandstone production line. Jaw crusher can be divided into PE series and PEX series, of which the PE jaw crusher is used for coarse crushing, and PEX jaw crusher for medium and fine crushing.

Applications of Jaw Crusher

Jaw crusher is mainly used to reduce the size of various materials. Coarse crushing, medium crushing and fine crushing are all available, the first two of which are the major functions. Jaw crusher can be applied to crush more than 200 kinds of hard and soft ore or stones with less than 300MPa compressive strength. The applied materials are commonly like pebble, calcite, granite, quartz, concrete, dolomite, bluestone, iron ore, limestone, coal gangue, construction waste, ferrosilicon, basalt, sandstone, cement clinker, etc. It is mainly used for the medium and fine crushing of hard ores and rocks in metallurgy industry, mine industry, chemical industry, cement industry, construction industry, refractory materials industry and ceramic industry and other sectors.

Working Principle of Jaw Crusher Machine

When a jaw crusher works, the motor starts the belt wheel to drive the centrifugal shaft to rotate. The movable jaw blade suspension shaft gets to and away the fixed shaft periodically, which causes a press, rubbing and grinding, etc. to the raw materials. Crushed stone falls down gradually and are discharged out of the jaw crusher when the particle size meets the requirements.

Structure and Advantages of Fote Jaw Crusher Machine

Jaw crusher is made of the frame, the eccentric shaft, a big belt pulley, the flywheel, a side guard plate, toggle plate, toggle plate backseat, clearance adjusting screw, a reset spring, a fixed jaw plate and a movable jaw plate, in which the toggle plate also plays the role of insurance.

• Stable and reliable performance with high strength. The bearing block is structured as an integral CS, which ensures the complete co-work with the crusher frame. Meanwhile, finite -element analyzing assures a high strength of jaw crusher.
• Advanced technology and wearable parts. The movable jaw blade is made of high-strength and wearable steel and driven by two large CS wheels. Besides, the heavy ccentric shaft is processed by forging stock.
• Simple operation and a safe working environment. The crushing cavity is symmetrically V-shaped; thus, the actual feeding port width is consistent with the nominal feeding port width. The outlet is more easily adjusted.
• High efficiency and energy-saving. The deep cavity gives fully crushing to the materials and improves the crushing ratio as well as the even particle shape.

When Should I Select Jaw Crusher?

Usually, jaw crusher is used as the primary and medium crushing machine for its large crushing capacity and crushing ratio. With the working principle of a simple pendulum and complex pendulum, jaw crusher has the discharge size of 10-350mm, which is suitable for the feeding port of most of the fine crushing machine. Therefore, if you need a machine for the primary crushing, a jaw crusher is the better choice. When it comes to the differences in jaw crusher V.S. impact crusher, here are mainly three points. 

First, as mentioned, the jaw crusher is used for coarse crushing and medium crushing, while the impact crusher is more often used as the fine crusher machine. Second, the jaw crusher works with simple pendulum and the complex pendulum by the fixed jaw and the movable jaw. As for the impact crusher, it works with rotating pendulum. Third, when mentioning the working mean, we always say that jaw crusher always works with regularly short interval while the impact crusher with no interval. Sometimes, impact crusher can be replaced with cone crusher. But jaw crusher plays a more irreplaceable part in crushing plants.

Classic Case of Fote Jaw Crusher

For its big crushing ratio and even particle shape, Fote jaw crushers have received global appraise and exported to more than 200 countries including South Africa, India, Philippine, Malaysia, America, Germany, Pakistan, etc. Here is one of Fote crushing solutions in Philippine with jaw crusher used in pebble crushing line. In this crushing plant, jaw crusher is used with a capacity of 120 TPH, feeding size of 500mm and discharging size of 3/4 ". This customer found our web on Google and left an online message with project details. Fote engineer contacted him through the email and WhatsApp. Then this Philippine customer got four solutions with different series of crushing machines in 24 hours after replying. Compared with different parts of other companies, he selected this plant. In 2017, this plant was installed and started operation. Up to now, the entire line has worked well with a low failure rate and got praised by our customer.
