C6X Jaw Crusher boasts more reasonable moment of inertia and greater crushing strokes through optimization of the equipment structure, crushing cavity and movable jaw's motion trail and speed. It is able to achieve higher crushing efficiency at the same power consumption and thus offer customers a larger rate of return on investment.
In order to ensure stable and efficient production during crushing hard materials, C6X Jaw Crusher is equipped with such core rotating components as high-quality casting movable jaw body, large-eccentric heavy-duty forged eccentric shaft, cast flywheel with a high moment of inertia and high-strength integrated cast steel bearing box, as well as strong power with reasonable speed configurations.
High-quality raw materials and reliable design can provide sufficient equipment strength and remarkable durability of C6X Jaw Crusher during super-hard material crushing and thus reduce the maintenance costs.
The C6X Jaw Crusher adopts centralized grease lubrication. Manual or automatic grease lubrication system can be configured as needed, which can reduce the difficulty in maintenance and simultaneously guarantee cleanness and neatness at the work site.
The C6X Jaw Crusher uses a double-wedge regulating discharge port with the mechanical or hydraulic regulation available as needed, so it can be regulated more simply and efficiently than the traditional underboarding discharge ports.
There are tens of lines of numerical controlling machine tools. Operations such as steel plates' cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.
SAINTWAH, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.
Firstly, the motor drives belt and pulley to make the movable jaw move back and forth, up and down around the eccentric shaft. When the movable jaw pushes the movable jaw plate towards the fixed jaw plate, materials get crushed. When movable jaw and plate move backwards under the action of the eccentric shaft and spring, the materials crushed before would be discharged from the port under the jaw plate. As the motor works continuously, the movable jaw can crush or discharge materials periodically, so that volume production can be achieved.
The jaw crusher is a large crusher installed and receives no-load testing in the manufacturer's workshop. However it is disassembled into components for transport. When receiving the product, the user shall check carefully the components with the packing list to identify and remove problems that could be caused during transport.
1. To avoid violent vibration caused in operation, this crusher shall be installed on reinforced concrete foundation. The weight of the foundation shall be roughly 8 to 10 times that of this crusher. The depth of the foundation shall be greater than that of the frozen land at local. The positions of anchor bolts for the crusher and motor as well as other dimensions can be found from the foundation drawing. Nonetheless, the foundation drawing may not be used as construction drawing. For these anchor bolts, holes shall be made in the foundation. Grouting in these holes shall be performed after anchor bolt placement. The elevation and size of the discharge chute shall be determined on site according to the discharge process.
2. After the grout hardens, tightening the nuts to anchor bolts. While doing so, measure the levelness of this crusher with a leveling gauge. Along the width of front wall of the framework, the levelness deviation shall be controlled to be less than 2mm. Framework levelness inspection is particularly important to prevent possible skewness of charge port which could cause charge from only one side and bring damage to the crusher because of uneven load.
3. When installing the motor, check the distance between it and the crusher, and whether its pulley corresponds to the crusher pulley so that all the V-belts run effectively in coordination.
4. The size of discharge port shall be adjusted according to granularity of materials and capacity of the crusher. Release the tension spring, adjust the discharge port size, and then tighten the tension spring to prevent the elbow plate detachment. For details, refer to the Component Adjustment Section.
1. To ensure normal operation and extend service life of the crusher, regular lubrication shall be performed.
2. Grease in the bearing block shall be replaced every 3 to 6 months. Before adding grease, clean carefully raceways of roller bearing by using clean gasoline or kerosene, with the drain hole at the bottom of bearing clock open. Add grease to 50% to 70% of the bearing block capacity.
3. Grease used for this crusher shall be selected according to altitude and climate. Generally, calcium base, sodium base, or calcium- sodium base grease may be used. And thick grease may be diluted with light oil.
4. Between the toggle plate and toggle plate pad, it is enough to apply proper amount of grease during assembly and inspection.
5. For reliable and quick application of grease to lubrication points, the lubrication mechanism is utilized (there are four lubrication points in this crusher, i.e. the four bearings). For lubrication time, refer to the drawing.
1. Movable jaw does not rotate while flywheel is rotating
2. Crushing plate shakes and makes collision noise
3. Thrust plate support makes collision noise or other abnormal noise
4. Flywheel comes loose
5. Increased granularity of crushed products
6. Crushing cavity blockage, resulting in current of main motor exceeds normal operation current
7. Excessively high bearing temperature
Preparation before foundation concrete placement
1. Set markings for placement thickness control, for example, horizontal standard piles or elevation piles. Printing horizontal standard lines on the wall of building or on the slope of groove or ditch, or nailing wood pegs of elevation there may also be used as alternative.
2. If groundwater level is higher than foundation ditch bottom, drain water or lower groundwater level so that no water appears in the foundation ditch.
3. Before concrete placement, relevant departments shall be organized to check for nonconformities of foundation ditch, including excessive deviations of axis and elevations, unacceptable geological conditions, and unnecessary holes, grooves or shafts. These nonconformities must be removed before concrete placement.
4. Check whether the slopes of foundation ditch and pipe duct are stable. Remove loose soil and accumulated water if any from the foundation ditch bottom.
If the crushing production line is ready for operation, you should pay attention to five points below:
1. With the main motor turned on, watch the ampere meter on the control cabinet. After the peak value lasting 30 to 40 seconds, the current shall drop to normal operation value.
2. Current during normal operation may not be greater than the specified value for a long period.
3. With the crusher in normal operation, turn on the feeding machine. Adjust the belt of feeding machine to change feeding rate adaptive to material size and crusher operation. Generally material stack height in the crushing cavity shall exceed two-thirds of the crushing cavity height, and material diameter had better not exceed 50%-60% of the charge port width. In this case, the crusher can reach maximum output. Excessive material size can cause blockage affecting production.
4. Prevent strictly foreign metallic parts (for example, blade tooth, track plate, and drilling bit) from entering the crusher, which could cause damage to the crusher. If you find some foreign metallic parts in the crusher, immediately notify next station in the production line to take them out, to prevent them from further entering the second-stage crushing system resulting in accident.
5. In case of automatic tripping of electrical component, do not turn on the crushing equipment until the cause has been identified and removed.
1. The newly-purchased equipment of sand-making line generally requires a long running-in period before being put into normal operation. In order to meet the production schedule or reap more profits, most users have not paid due attention to the warnings of running-in period. Some of them even think that anyway the warranty period has not expired and it is the manufacturer's responsibility to repair damaged equipment. They have the production line operating under overload for a long time. Consequence is frequent occurrence of breakdown. However this cannot only shorten the service life of equipment but also cause production interruption due to damaged equipment. In this end, importance shall be attached to the correct use and maintenance of sand-making line during running-in period.
2. Problems at different severity levels could occur due to long time operation of sand-making line. How to solve minor problems? Inexperienced persons could be in a muddle, failing to find a way out and just worsening the situation. The key is to find and remove the cause. For the sand-making line, synchronization or coordination between equipment is of great importance, especially for the feeding and conveying equipment. Out-of-synchronization between equipment probably causes local even broad blockage, with production line efficiency seriously reducing and equipment damaging. The sand-making line manufactured in SAINTWAH Group is a highly-integrated production line consisting of ore-addressing equipment and other mining equipment. It has passed the tests performed by experts and users. It is popular for energy saving and simple operation. What is more important is that it doubles output compared with the previous sand-making line. It is suitable for handling both soft and very hard materials, and can also efficiently handle highly wet materials without blockage.

The granite is evenly fed by ZSW490*130 feeder into PEW1100 European hydraulic jaw crusher for coarse crushing and then gets into CSB240 cone crusher for secondary crushing.
Two production lines are installed together. Each production line configuration is as follows: ZSW490*130 vibration feeder (1 set), European hydraulic jaw crusher PEW1100 (1 set), CSB240 cone crusher (1 set), HPT300 multi-cylinder hydraulic cone crusher (12 sets), 3Y2460 circular vibrating screen (2 sets), 2Y2460 (1 set), VSI5X114593 sand-making machine (3 sets), 3Y2460 (3 sets).
The granite is evenly fed by ZSW490*130 feeder into PEW1100 European hydraulic jaw crusher for coarse crushing and then gets into CSB240 cone crusher for secondary crushing. Furthermore, the material after being crushed would get into 2Y2460 for screening where the unqualified material would be sent back for another crushing while the material less than 150mm gets into HPT300 for third stage crushing. When the material is less than 40mm, it would enter into VSI5X-1145 impact crusher for shaping. After this step, the customer can get finished products whose sizes are 0-5mm 5-10mm, 10-20mm respectively.
