subject: About The Main Advantages Of Gyratory Crusher [print this page] The advantages of gyratory crusher (compare with jaw crusher):
1. Crushing cavity depth, work successive, high productive capacity, the unit consumption is low. Compare with the same give mine mouth width jaw crusher, the productive capacity of gyratory crusher is more than twice as it, and the current drain per ton of gyratory crusher is Low 0.5-1.2 times than jaw crusher.
2. Work smoothly, vibration is lighter, machines based weight is smaller. The based weight of gyratory crusher is usually 2-3 times of the machine weight, but the based weight of jaw crusher is usually 5-10 times of the machine weight.
3. Can be packed with gives the ore, the large gyratory crusher can directly into the original ore without additional ore nodes and gives the ore machine. But jaw crusher can't full requirements for ore and require the ore gives evenly, so it needs to another mine set ore nodes (or give ore funnel) and gives the ore machine. When the ore block degrees than 400 mm, it needs to install expensive heavy plate gives the ore machine.
4. Gyratory crusher is easy to start, unlike jaw crusher before starting the auxiliary tool rotation needs heavy flywheel (subsection startup jaw crusher exception).
5. Gyratory crusher products flake products is less than jaw crusher.
The disadvantage of gyratory crusher (compare with jaw crusher):
1. Gyratory crusher airframe is higher than the jaw crusher 2-3 times generally, so the construction cost is bigger.
2. It doesnt suitable for broke damp and viscous ore.
3. Installation, maintenance is more complex, and overhaul isnt convenient.
In the design of coarse crushing equipment, it also considers the nature of the ore, the product's request, the mill particle size and equipment conditions items. General situation is: when processing sheets and strip shape hard ores, even need more than two jaw crusher can meet the production requirement, but can be used a gyratory crusher replace, it should give priority to gyratory crusher. Especially crushing plant configuration in slope topography, the solution is more favorable. When broken damp and viscous ore, or production smaller medium and small mill, it appropriate chooses jaw crusher. As for pit, it is usually under broken with jaw crusher. It must be pointed out that when choose the equipment, it should do technical and economic scheme comparison, and choose preferentially.
