Working Principle

Motor drives eccentric bushing to rotate via V-belts, pulley, shaft, pionion, gear.

Manile rotates with eccentric bushing, so manile goes near and far from the concave, and crush stone into smaller size.

Features Of The Symons Cone Crusher

1. High-performance: Combining optimal designing of chamber type with applying reasonable speed and stroke, to make this kind of machine does more work with the same dynamic cone diameter. Therefo, this machine is of high-performance and manufacturing capacity compared with other cone crusher of the same type.: Use Iminated crushing principle, to make more cubic shape materials and less needle-like materials.
2. Good products size composition: The crusher applys for laminated crushing principle to make cubic shapes of final products stand for larger proportion. Adicular and flake shape products decrease and size fraction much more well-proportioned.
3. Good stability: If there is metal or other non-broken material come to the chamber, metal going through protection device will release it and then reset automaticly. The protection device has fixed discharge opening returning point and the original discharge opening can returing back immediately after the metal goes through the crushing chamber.
4. Convenient Cleaning-up: If the crusher stops under loading condition, hydraulic cleaning system can clean up the crushing chamber quickly so that decrease the downtime.
5. High reliability.: Adopting main shaft with big diameter, heavy main frame and separate automatic Control System of thin oil lubrication system, so that it guarantees robustness and reliable operation of the crusher.
6. Easy maintenance and operation: All parts can be disassembled from top and the upper side, so that fixed cone and dynamic cone can be disassembled easily. Under high shock and vibration environment, bronze Bearing can keep excellent bearing capacity and it is much more economic and easy for maintenance.
7. Low production costs: Due for big capacity, high reliability and easy maintenance, the production costs has been recuded greatly.
8. Widespread use: The speciality of CS Series High-efficiency Spring Cone Crusher is maximizing the performance to apply to all kinds of crushing process: from special coarse crushing to fine crushing; from fixed crushing plant to mobile crushing plant. CS Series High-efficiency Spring Cone Crusher has different types of crushing chamber for choosing according to crushing process.

The Lubricating System

Since the friction surface receives much pressure, lubrication is very important to the crusher. The crusher is centrally lubricated with watery oil.

Oil route

There are two routes for the oil to enter the machine,

• one is through the oil hole at the bottom of the crusher, then to the hollow eccentric shaft surface, bowl-shaped bearing and the big and small gears through 3 separate ways.
• The other is through the hole in the transmission shaft support, then to the transmission bearing. The return route is a spill hole at the bottom of the small bevel gear and another spill hole in the dust-proof cover.

Adjustment and locking of hydraulic system

• Start thin oil station before start the main unit, if the lubrication system is ok, start the main unit, then start the vibrating feeder if the machine running normal without load. Stop feeding before stop crusher, ores in crushing chamber is exhausted totally, stop the main unit, and stop the thin oil station at last.
• Before start the thin oil station, open relative oil valve and switch, adjust the pressure adjust device, keep the pressure between 0.04-0.1MPa, the oil temperature should be in 30-40°C, if the temperature is too low, start the resistance heater first.
• Please refer to the electricity control cabinet instruction for all electric switch function. And put them in proper position before start the main unit.

Problem and solution

Trouble	Cause	Troubleshooting
1. Oil flow indicator shows no flow. Oil pump is running, but oil pressure is less than 0.04 MPa.	1. Low oil temperature; 2. Oil path switch not started properly; 3. Oil pump malfunction.	1. Heat the oil; 2. Check the oil path switch; 3. Overhaul or replace the oil pump.
2. Excessive pressure difference between the inlet and outlet of the filter.	Clog in the filter.	Clean the filter when the pressure difference exceeds 0.05 MPa.
3. Oil pressure and oil temperature increase.	Oil pipe or oil path blockage.	Stop the machine, locate the blockage, and remove it.
4. Oil temperature exceeds 60°C, but oil pressure does not increase.	Problem in rolling friction parts.	Stop the machine and check the ball tile, bushing, and thrust mat. Identify the cause and resolve it.
5. Oil level decreases.	1. Leakage at the machine bottom end cap; 2. Leakage at the transmission shaft flange; 3. Blockage in the bowl bearing base or oil return passage.	1. & 2. Stop the machine, tighten bolts or replace the mat; 3. Stop the machine, check and clean the oil path and passage, adjust oil level, and resolve the issue.
6. Water enters the oil; oil level increases.	1. Water pressure higher than oil pressure in the cooler; 2. Water leakage in the cooler; 3. Excessive water in the water seal; 4. Blockage in the water return pipe.	1. Adjust water pressure to be lower than oil pressure; 2. Check for leaking parts; 3. Adjust water amount; 4. Clean the water return pipe and oil tank; replace with new oil.
7. Oil in water seal; oil temperature does not increase.	Oil passage blockage.	Clean the oil tank and oil return pipe.
8. Crusher vibrates strongly; cone rotates too fast.	1. Lack of oil or dust in oil between main unit and bushing; 2. Damaged bowl tile; 3. Insufficient gap in cone bushing.	Stop the machine, identify the cause, and take appropriate action.
9. Frequent vibration during machine operation.	1. Insufficient spring pressure; 2. Feeding of fine and sticky material; 3. Uneven or excessive feeding.	1. Tighten the spring nut or replace the spring; 2. & 3. Adjust feeding appropriately.
10. Crushing chamber moves upward with strong noise, then returns to normal.	Uncrushed material entering the crushing chamber, which may cause main shaft breakage.	Remove iron objects before feeding; use a metal detector.
