JC Series Jaw Crusher

Working Principle:

The processed materials in the jaw crusher are crushed between two hard surfaces. The movement of the moveable surface is the load of the jaw crusher. The effect of crushing is realised by the movement of the moving jaw with the fixed jaw and side lining plate in the broken cavity. The material block (i.e. rock or ore) is clamped, squeezed and broken between the moving jaw and the fixed jaw.

The quality and quantity of the processed materials depend on the interaction between the jaw crusher and the materials. The geometric shape of the broken cavity.The dynamic characteristics of the crusher and the nature of the treated material are the most important influencing factors.

The power from the driving motor is transmitted from the triangular transmission belt to one of the flywheels installed at the end of the eccentric shaft. The rotation of the eccentric axis and the movement of the elbow plate cause the moving jaw to produce an elliptical trajectory. When the distance between the two jaw plates narrows, the material entering the crushing cavity is squeezed and broken. When the moving jaw moves in the direction of leaving the fixed jaw, the material falls and discharges the crushing cavity.

Product Instructions for Use:

1. Check that the CSS of the jaw crusher (tight edge discharge ore) is not less than the recommended value.
2. Start the crusher and make it run under no-load for 2 hours, and check it as follows at the same time:
   1. Has the safety cover been installed in place?
   2. Is the rotary direction of the flywheel of the crusher correct?
   3. Whether there is abnormal noise.
   4. Whether the bearing is overheated.

3. Correct the errors found during this period. After making sure that everything is normal, carefully send the materials into the crusher, and send the materials.When entering, it should be evenly distributed along the width of the feed port of the crusher. The feeding block should not be greater than the feeding port shown in the figure.

Product Maintenance:

1.In order to ensure the best performance of the jaw crusher, the feeding must be uniform. It is not allowed to enter large pieces of materials that exceed the size of the feeding port marked.

2.In the first month or 160 operating hours, check every day whether there is old grease sealed from the bearing maze.The circle is extruded. If not, grease the bearing will be filled with grease. Check the bearing temperature regularly. Check the tightening of all threaded joints.

3.Overloading the crusher should be avoided. The causes of overload are:

– Abnormal wear of the jaw plate (concave or “sled shape”).

– The excessive wear of the jaw plate or the bow shape of the jaw plate.

– The set value of the discharge port is too small.

– There are too many fine materials in the feed.

Application scenario:

JC series jaw crusher is a heavy-load, large-capacity and high-stability coarse crushing equipment, which is widely used in mines, sand and stone, infrastructure, solid waste recycling and other scenarios. It is the core first crushing equipment of large and medium-sized crushing production lines.

1. Mine ore crushing

It is suitable for coarse crushing of granite, basalt, river pebbles, iron ore, gold ore, copper ore and other hard ores. The fuselage has high strength and strong impact resistance, and can be continuously overloaded for 24 hours, adapting to the high-capacity production needs of large-scale open-air mines and beneficiation plants.

2. Production of sand and stone aggregates

It is widely used in commercial sand and stone yards and aggregate processing factories, supporting cone breakers and vibrating screens to form a complete production line. The finished product has a uniform particle shape and a stable production capacity, which is suitable for high-speed, water conservancy, municipal, concrete mixing station and other high-standard engineering aggregate production.

3. Construction waste solid waste regeneration

It can crush waste concrete, bricks, steel slag and crushed stone waste, and process solid waste into recycled aggregates. It is suitable for site recycling, resource reuse, environmental protection and adapts to flexible construction scenarios.

4. Crushing of building materials and industrial raw materials

It is used in cement, chemical industry, refractory materials and slag processing industries. Limestone, gypsum and ore block materials are pretreated. The equipment is stable and the failure rate is low, and it is suitable for long-term industrial continuous production.

5. Overseas large-scale projects and whole-line support

Adapt to overseas large-scale quarry, engineering general contractor and agent complete set of projects. With Mn13Cr2 and Mn18Cr2 high wear-resistant accessories, the wear-resistant service life is longer. Conventional accessories are always in stock and can be supplied for a long time. It supports non-standard customisation to meet the needs of overseas whole-line procurement and long-term operation and maintenance.

FAQ：

Q: Which materials are suitable for JC series jaw crushers?

A: JC series jaw crushers are mainly used in the coarse crushing stage of various high-hardness and medium-hardness ores, especially suitable for the initial crushing of large materials. Common materials include granite, basalt, river pebbles, iron ore and quartzite, etc. In the production of mines and sand and stone aggregates, this equipment can stably process high-strength materials and provide suitable feed particle size for subsequent medium crushing and fine crushing processes.

Q: What kind of production line configuration is suitable for JC series jaw crusher?

A: JC series jaw crusher is usually used as the coarse crushing equipment of the whole crushing and screening production line, which is located in the first part of the production process. In practical applications, it is usually combined with cone crushers or counter-impact crushers, sand-making machines and vibrating screens to form a complete sand and stone aggregate production system. According to different output needs, small and medium-sized or large-scale mine production lines can be formed to achieve continuous and stable production.

Q: How to choose the model of JC series jaw crusher?

A: The choice of JC series jaw crusher model mainly depends on the material hardness, feed size and yield demand. Small and medium-sized sand and stone production lines can choose medium-capacity models, while large-scale mining projects are recommended to choose high-yield specifications. For granite, basalt and other high-hardness materials, higher-specification equipment should be given priority to ensure stable crushing capacity and operation efficiency.

Q: How to transport the JC series jaw crusher?

A: Before the equipment leaves the factory, standard reinforced packaging is adopted, container or bulk transportation is selected according to different sizes, and anti-rust and anti-collision treatment is provided. We can assist in sea transportation and customs clearance to ensure that the equipment is safely delivered to the project site.

Q: Do you support agency cooperation and long-term supply?

A: We support global agency, distribution and long-term cooperation models, and can provide factory prices, technical support and a stable supply system. Provide product information and market support for partners to facilitate local marketing.

Q: Do you provide long-term supply of consumable parts?

A: We supply JC series jaw crusher consumable parts for a long time, including jaw plate, side guard plate, elbow plate, etc., which are made of high-manganese steel or alloy materials, with good wear resistance, and support long-term spare parts supply.
