75mm inlet size low price spring cone crusher crushing machine from manufacture

This kind of spring cone crusher is widely used in metallurgy, road building, mining, silicate and chemical industry, you can select suitable type according to different need of users.

Detailed introduction

Cone crusher is a kind of crushing machine commonly used in mining, metallurgical industry, construction, road construction and chemical industry. Cone crusher can be used to crush hard and medium hard minerals, rocks, iron ores, limestone, copper ores, quartz, granite, sandstones, etc.
This crushing equipment has compact structure and high productivity, the size of the discharge opening can be adjusted by propelling cylinder, this machine adopts grease seal to avoid mixing of water and oil.

Working Principle

1. When cone crusher is working, motor drives the eccentric sleeve to rotate. The eccentric sleeve drives the transmission shaft and cone part to make swing movement. When they swing to the extent that the surface of the crushing wall is close to the roll mortar wall, the rocks and ores are pressed and crushed.

2. Joint between supporting sleeve and frame is compressed by spring. When metal block and other materials that can no be crushed fall into the crusher, spring will be out of sharp and discharge the objects.

3. When the materials that can not be crushed pass through the crushing chamber or the machine overloads, the spring safety system makes the cone discharging hole become larger. When objects are discharged from crushing chamber, discharging hole will automatically reset. Cone crusher resumes normal operations.

4. The surface of crushing chamber is covered with wear-resisting high manganese steel lining plate. Size of discharging hole can be adjusted hydraulically or manually.
