Granite sand making machine:
Granite sand making machine (cone crusher) is widely used in metallurgical industry, building materials industry, road building industry, chemical industry and silicate industry. Granite sand making machine is used for medium and fine crushing hardness f ≤ 5-16 all kinds of ores and rocks. Crusher structure consists of the frame body, adjusting device, adjusting sleeve, crushing cone, transmission and other major parts and eccentric and electrical, lubrication and other auxiliary components. PY series granite sand making machine divided into coarse crushing, secondary crushing and fine crushing granite sand making machine. The series crusher is suitable for crushing medium hardness above ores and rocks. Types of crushing chamber can be decided by ore usage, the standard type used in pieces; medium suitable for medium crushing; short head type is suitable for fine crushing. According to the different needs of users to buy.

Granite sand making machine working principle:
When granite sand making machine works, rotation of the motor through the pulley or coupling, drive shaft and the eccentric sleeve conical portion moving force for rotation about a fixed lower pendulum movement, so that the crushing cone crushing wall sometimes close and sometimes leave the solid mounted on the adjusting sleeve is rolled white wall surface, so that the ore in the crushing cavity constantly under attack, pressing and bending role to achieve ore crushing.

When foreign matter not be broken through the crushing chamber or some resson, occur overload, the spring safety system achieve insurance, port of discharge increases, the foreign body is discharged from the crushing cavity, such as foreign body stuck in the discharging ore port,can be used cavity clearing system, so that the drain mine continues increases, discharging mine mouth automatically reset, the machine back to work. This series crusher can be divided into coarse crushing,medium crushing and fine crushing. 

Granite sand making machine features:
1. high crushing force, high efficiency, high handling capacity, low operation cost, easy adjustment and economic characteristics.
2, due to parts selection and structural design is reasonable. Therefore, long life, and broken product size uniform, reducing the load cycle.
3, granite sand making machine adopts grease sealing. Water supply and drainage system to avoid the shortcomings and easy to plug the defect of mixture of water and oil.
4, spring safety system is the overload protection device allowing foreign substance or ironthrough the crushing chamber without damage to the crusher.
5, granite sand making machine is divided into standard type and short head type, in general, standard large feed size, nesting coarse granularity, short head type cone crusher steep feed size less conducive production of fine grade material. Therefore, standard type generally used for coarse, medium broken, short head type is used, the crushing.
6, in the medium and large-sized crusher, using a hydraulic clean cavity system reduces downtime and specifications of each crusher cavity so that the user can choose according to the different needs of different cavity to better adapt to user needs.

Granite sand making machine is used in metallurgy, construction, road building, chemical and silicate industry for crushing raw material, can crush medium and above medium hardness ores and rocks. Granite sand making machine has large crushing ratio, high efficiency, low energy consumption, uniform particle size, suitable for a variety of pieces and crushing ores, rocks.
