A gyratory crusher is an ore crushing machine that uses a gyrating cone to crush ore. The cone is powered by a motor, which rotates the cone around a central axis. The axis of the cone can be either horizontal or vertical, and the cone can be either inverted or not. Inverted cones are used for crushing hard rock, while non-inverted cones are used for soft rock.
The main advantage of using a gyratory crusher over a jaw crusher is that the gyratory crusher does not require as much force to crush the ore. This is because the jaw crusher relies on gravity to crush the ore, while the gyratory crusher uses centrifugal force. Additionally, the gyratory crusher is able to operate at a higher speed than the jaw crusher, which means it can crush more ore in a given period of time.
A jaw crusher is typically used as the primary crushing machine in a quarry or ore processing plant. It uses compressive force to break rocks or ores into smaller pieces. A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head, both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate, the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.
What are the disadvantages of using a gyratory crusher over a jaw crusher? First, the gyratory crusher requires a higher initial investment than a jaw crusher. Second, the gyratory crusher has a higher operating cost than a jaw crusher. Third, the gyratory crusher produces more dust than a jaw crusher.
There are several reasons why a gyratory crusher would be selected over a jaw crusher in mine or ore processing plants:
1. Higher capacity. A gyratory crusher can handle higher capacities than a jaw crusher. This is due to the fact that there is a larger Eccentricity (distance between the two crushing surfaces) and a longer stroke at the bottom of the cone. The greater distance allows for coarser material to be crushed as well as increased throughput.
2. Decreased downtime. A gyratory crusher has a shorter downtime than a jaw crusher because of its higher productivity and reliability.
3. Easy maintenance. A gyratory crusher is easier to maintain than a jaw crusher because it has fewer parts and its simple mechanism is less prone to breakdowns and malfunctions.
4. Cost-effective. A gyratory crusher is more cost-effective than a jaw crusher because it requires less investment in terms of infrastructure and equipment.
Rotary crusher has many advantages and disadvantages compared with jaw crusher. Therefore, it is necessary to select appropriate crushing equipment according to its actual needs to maximize its benefits.If you are interested in our equipment, you are welcome to consult, and we look forward to your arrival.
