A brief introduction of Symons cone crusher

Symons cone crusher is also known as compound cone crusher. It is developed and improved by introducing and absorbing the foreign technology to meet customer’s needs, and also a modern high-performance cone crusher with high swing frequency, optimized cavity and reasonable stroke on the principle of laminating crushing and more-breaking and less-grinding concept design. It is mainly exported to Zimbabwe, Pakistan, India, Tanzania and other Africa and Asia regions. Compared with the traditional spring cone crusher, Symons cone crusher has the features of reliable structure, high productive efficiency, easy maintenance and cheap prices, etc.

Working principle and parts applications

Working principle

When Symons cone crusher works, the motor drives the eccentric sleeve rotating through the V-belt, the large pulley, the transmission shaft, the bevel gear, and the large bevel gear. The conical shaft core rotates and moves by the driving of the eccentric sleeve, causing the surface of the broken wall to be close or leave the surface of the rolling wall, therefore, the material is continuously crushed by the crushing and bending in the annular crushing cavity composed of the fixed cone and the moving cone. After multiple extrusion impacts and bending, the material is crushed to the required particle size and discharged through the lower portion.

Parts and their applications

Main parts Practical applications
Frame Keep the machine in place and protect it to reduce the abrasion.
Spring Increase and reset the discharge port.
Transmission device Transfer power to drive system so that mobilize cone plate to crush materials
Adjustment ring Adjust the size of the crusher discharge port by raising or lowering the fixed cone.
Concave, mantle Squeeze each other to crush material
Hydraulic system Overload protection.
Eccentric sleeve assembly Consisting of eccentric sleeve, eccentric shaft sleeve, pinion, counter weight and its shield, rotating eccentric sleeve can get different eccentric distances, optimize products’ curve and improve productivity.

How to use and maintain Symons cone crusher

The maintenance and application

  • 1. Lubrication oil station should be turned on and make sure that the system has been already lubricated and then turn on main engine. After crusher idling normally, switch on feeding machine. The crusher should stop feeding before stopping, and the mine should be all crushed and discharged, and then the circular vibrating and screening locomotive can be stopped, and finally closing the oil pump of the lubrication oil station.
  • 2. Before turning on pump of lubrication oil station, open the oil and water valve and turn on pressure gauge lubrication oil station. Adjust the pressure regulator so that the oil supply pressure is within the range of 0.08 to 0.2 MPa, and the oil temperature should be within the range of 30℃to 45℃. If the oil temperature is too low, turn the resistance heater to heat the oil.
  • 3. For the function of each electrical switch, please refer to the circuit description, and all the switches should be kept in the appropriate place.

Potential faults and elimination methods

Potential faults Main reasons Elimination methods
There is no oil flow indicated in oil flow indicator. The oil pump works but oil pressure is lower than 0.08 MPa. 1.Low oil temperature 1. Heat the oil
2.The switch of oil system is out of position. 2. Check the oil switch
3.The pump is not working well. 3. Repair or replace the oil pump
The crusher vibrates strongly and the movable cone rotates very quickly 1.There is lacking of oil between main shaft and sleeve or there is dust in oil. Stop to check and find out the cause for symptomatic elimination
2.The movable cone is sunk due to broken socket liner or manufacture failures
3.Insufficient gap of cone sleeve
The crushing cavity produces a strong knocking sound while lifting up, and then works normally. When the non-crushed material (over-iron phenomenon) falls into the crushing cavity, the main shaft is broken and the machine is damaged. Strengthen iron removal work and adopt automatic iron removal devices such as metal detectors
Produce audible cracks when crushing or idling 1.Movable cone or fixed cone liner loose 1.Fasten bolts and recast alloy
2.Screw or earring is damaged 2.Remove the adjustment ring, change the screws and earrings
3. Crushing cone or fixed cone liner is not round and generates impact 3. Check the roundness of the liner during installation and machining if necessary
Crusher with load suddenly stopped 1.The oil temperature rises, the oil level and oil pressure are too low, causing the relay works. 1.Check oil temperature, level, pressure and the chain reactions to find out the cause and eliminate it
2.Oil pump or other equipment that has a chain reaction with the crusher has failed 2. Open the electrical switch, remove the ore in the crushing chamber; when the power recover, and then start according to the regulations.
3.There is a large non-crushed material entering the crushing chamber to get stuck in the crusher 3. Open the clearing system to make the stuck non-crushed materials fall

How to detect hydraulic system

The hydraulic system is one of the important devices for the Symons cone crusher. When faults occur, the crusher often appears abnormal phenomenon in advance. Crusher should be checked and maintained regularly. Finding and removing small fault has great significance in the prevention of major fault.

  • 1. Before working, the hydraulic cone crusher system should be carefully checked whether the fasteners and pipe joints are loose or not, and whether the pipes are deformed or damaged.
  • 2. Hydraulic pump should be full of oil before first working so that to prevent idling destroying hydraulic pump.
  • 3. When the hydraulic pump works, it can be operated continuously (especially in cold areas) to see if the operation is flexible. The crusher starts working after confirming that the operation is normal and there is no abnormal noise.
  • 4. The pressure of distribution valve in hydraulic system can be changed by crusher if the value is more or less than specified value.
  • 5. After the hydraulic cone crusher system working stably, we should pay attention to the oil temperature, pressure, sound, etc., and also pay attention to the observation of hydraulic cylinders and motors, reversing valves, relief valves and other components, as well as the working condition of the crusher and oil leakage and vibration of the entire system.

Features and advantages of Symons cone crusher

  • 1.Each type of Symons cone crusher has a various crushing cavity, so the user can choose crushers with different crushing cavity for better meeting their different needs.
  • 2.Symons cone crusher has advantages of large crushing ratio, high efficiency, high capacity, low operation cost, easy to adjust, economic and other characteristics. Due to the better materials selection and structure design, it has a longer service life, and crushed product has more uniform size.
  • 3.Seal grease can avoid the shortcomings and defects of easy plugging of water supply and drainage system.
  • 4.Spring insurance system is overload protection device, which can protect the crusher when there is foreign substance in crushing cavity.
