High performance: through the optimization design of cavity and the combination of reasonable speed and stroke, this machine can do the most work under the same moving cone diameter. Therefore, compared with the same type of spring cone crusher, it has higher performance and production capacity.
Good particle size composition: by adopting laminated crushing principle, the proportion of cubes in the products is obviously increased, the needle-like pebbles are reduced, and the grain size is more uniform.
3, good stability: when a piece of iron and other non-broken material into the machine, the iron protection device will automatically release it, and then automatically reset. The overcast protection has a fixed outlet return point, and the impurity iron can quickly recover the original discharge port after passing through the crushing chamber.
4, convenient cleaning: if the spring cone crusher stops under load, the hydraulic cleaning system can clean the broken cavity quickly, greatly reducing the downtime.
5, high reliability: adopt the automatic control system of large diameter spindle, heavy duty main frame and independent thin oil lubrication system, ensure the equipment durable and reliable operation.
6, easy to maintain and easy to operate: all components can be removed from the upper or side, so fixed cone and moving cone assembly can be easily removed. Bronze sliding bearings can maintain excellent bearing capacity in high impact vibration crushing environment, and are more economical and easier to maintain than rolling bearings.
7, low production cost: due to large production capacity, high reliability, easy maintenance, greatly reduced production costs.
9, split lubrication: multi-point control independent thin oil lubrication system, can ensure the dual protection of the lubrication of the bearing, as well as the automatic safety protection of the whole machine.
