Main advantages and bad sides about cone crusher

Cone crusher is used for crushing of ores and rocks, the advantages are: reliable structure, high efficiency, easy-to-adjust and economical. The safety spring system is the overload protection device, which makes foreign material goes through the machine without bring any hurt to it. The sealing modes are oil and water, which segregate the stone powder and lubricting system. The crushing chamber is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.

When select the coarse crushing equipment in the crushing design, should consider the ore character,and the finished products size requirements, benefication plant scale,etc. We suggest that when crush the hard stones and long shape of stones,only need two ore three sets of jaw crushers to meet the requirements, and one cone crusher can replace, so you should select the cone crusher firstly. Specially for the clinoform terrain, this design is more favorable. When crush the wet and the sticky ores, or in the medium sized,small-sized benefication plant, jaw crusher is suitable.

Cone crusher(compare with the jaw crusher) main advantages:

1. Crushing cavity is largedepth, work successive, high productive capacity, low electric consumption .Compare the same width inlet of the jaw crusher, the production capacity is higher twice than the jaw crusher, the electric consumption of every ton of ores is lower 1.5-2 times than the jaw crusher.

2. Stably working,light vibration,equipment base weight is smaller. The cone crusher base weight is the body weight ‘s 2-3 times. the jaw crusher ‘s base weight is 5-10 times than the machine body weight.

3. Cone crusher can feed ores fully, large cone crusher can feed raw ores directly, no need to add hopper or feeding machine.But jaw crusher can’t feed fully with the inlets,jaw crusher require feeding materials evenly, and will build hopper and vibrating feeder, when the ore size larger than 400mm, need to install heavey duty of feeder.

4. Cone crusher is easy to start, jaw crusher need the auxiliary equipment to start the flywheel rotating(except the stage jaw crusher start)

5. Cone crusher will produce less sheet shape of products than the jaw crusher.

But cone crusher also has the disadvantages(compare with the jaw crusher):

1. The gyratory machine body is higher, higher than the jaw crusher twice or three times, the builing workshop cost is larger.

2. The cone crusher weight is large, the weight is larger 1.7-2 times than the same feeding sizeof jaw crusher, so the equipment cost is large.

3. Cone crusher is not suitable to the wet and sticky ores.

4. Complex of installation and maintainance.
