introduction
To understand the difference between single cylinder and multi-cylinder cone crusher, we must first look at the working principle of cone crusher. Cone crusher in the process of work, the motor through the transmission device to drive the eccentric sleeve rotation, the moving cone in the eccentric shaft sleeve forced to do rotation swing, the moving cone near the static cone section is a crushing chamber, the material by the moving cone and static cone multiple extrusion and impact and broken. When the moving cone leaves the section, the material that has been broken to the required particle size falls under its own gravity and is discharged from the bottom of the cone.
01 Structure
Single cylinder hydraulic cone break is mainly divided into six parts:
1. Lower frame assembly: lower frame, lower frame protection plate, lower frame lining plate, eccentric sleeve bushing, sealing bucket.
2. Hydraulic cylinder assembly: middle friction disc, lower friction disc, hydraulic cylinder block, cylinder liner, cylinder bottom, displacement sensor.
3. Drive shaft assembly: grooved wheel, drive shaft, bearing, drive shaft bracket, small bevel gear.
4. Eccentric sleeve assembly: counterweight ring, eccentric sleeve, large bevel gear, main shaft bushing.
5. Moving cone assembly: main shaft, moving cone body, rolling mortar wall.
6. Upper frame assembly: upper frame, rolling wall, pad cap, shelf body protection plate.
Multi-cylinder hydraulic cone breakage mainly includes six parts:
1. Lower frame: frame, spindle, guide pin.
2. Eccentric sleeve: eccentric sleeve, balance ring, large bevel gear.
3. Transmission part: drive shaft, small bevel gear, shaft sleeve.
4. Support sleeve: support sleeve, locking cylinder, locking nut.
5. Adjust the ring: adjust the ring and roll the mortar wall.
6. Moving cone: broken wall, cone head, spherical tile.
02 Comparison of discharge port adjustment devices
Single cylinder: During normal operation, the main shaft cylinder is injected or discharged by the oil pump, so that the main shaft is moved up or down (the main shaft is floating up and down), and the size of the discharge port is adjusted.
Multi-cylinder: Through the hydraulic push hand or hydraulic motor, adjust the adjustment cap, fixed cone spiral rotation up and down to achieve the adjustment effect.
03 Comparison of overload protection
Single cylinder: when the iron is over, the hydraulic oil is injected into the accumulator, and the main shaft falls; After passing the iron, the accumulator will press the oil back and the crusher will run normally. Hydraulic pump is also used when cleaning the cavity.
Multi-cylinder: When overloaded, the hydraulic safety system realizes safety, the discharge port increases, and the foreign matter is discharged from the crushing chamber. Under the hydraulic system, the discharge port automatically resets and the machine works normally.
04 Lubrication system comparison
Single cylinder: two inlet oil injection all the way from the lower end of the spindle into; The other way enters from the end of the drive shaft, and the last two ways of oil discharge from the same oil outlet.
Multi-cylinder: After one oil hole enters the machine from the lower part of the machine, after reaching the middle of the spindle, it is divided into three branches: the inner and outer surface of the eccentric sleeve, the middle oil hole of the spindle reaches the ball bearing, and lubricates the large and small bevel gear through the hole; The other is fed through a hole in the drive shaft frame to lubricate the drive bearing.
05 Comparison of crushing force components
Single cylinder: The hydraulic cone break is similar to the spring cone break, the spindle is combined with the moving cone, and the bowl is carried at the same time. The spindle and the moving cone are used as the base support, and the frame is subjected to tensile stress.
Multi-cylinder: hydraulic cone broken spindle is short, directly supported by the frame, providing a high bearing capacity, eccentric sleeve directly drives the moving cone to provide the crusher. The frame is subjected to reduced tensile stress. The multi-cylinder cone machine has advantages in frame construction.
06 Crushing + production
Compared with the single cylinder hydraulic cone breaking, the breaking effect is better, and the passing capacity is large. The multi-cylinder hydraulic cone breaking under the discharge port of fine material content is high, fine crushing effect is better, laminating crushing effect is good.
When crushing soft ore and weathered ore, the advantages of single cylinder hydraulic cone breakage are prominent, and when crushing medium hard and high hard ore, the performance of multi-cylinder hydraulic cone breakage is more outstanding.
Under the same specifications, multiple cylinders can produce more qualified products, in general, the harder the hardness, the greater the difference between the two.
07 Use and Maintenance comparison
Single cylinder: simple structure, reliable performance, one hydraulic cylinder, low failure rate, low production cost). Multi-cylinder: the top or side can be disassembled, fast and convenient maintenance, no need to disassemble the mounting frame, fastening bolts.
Through the above introduction, we understand that single cylinder and multi-cylinder cone crusher are high-performance crushers, and the different structure makes them have their advantages and disadvantages.
Compared with single cylinder, multi-cylinder is more dominant in structural performance, maintenance, crushing efficiency, etc., and the price of multi-cylinder hydraulic cone breakage will be high.
