Do you know cone crusher?

Cone crusher is a kind of crushing machine suitable for raw materials in metallurgy, การก่อสร้าง, การก่อสร้างถนน, chemical and silicate industries. According to different crushing principles and different product particle sizes, it is divided into many models. Crusher is widely used in many departments such as mining, การถลุง, วัสดุก่อสร้าง, ทางหลวง, ทางรถไฟ, water conservancy and chemical industry. เครื่องบดกรวย has large crushing ratio, ประสิทธิภาพสูง, การใช้พลังงานต่ำ, ขนาดอนุภาคผลิตภัณฑ์เครื่องแบบ, เหมาะสำหรับการบดขยี้แร่และหินที่หลากหลายและละเอียด. The models are mainly divided into SMG series, spring type and HPC series.

Do you know how does a cone crusher work?

The crushing process is completed between the fixed cone and the gyratory moving cone.

When the cone crusher is working, the horizontal axis of the crusher is driven by the motor through the V-belt and the pulley. The horizontal axis drives the eccentric sleeve to rotate through the large and small gears. The cone shaft of the crusher generates eccentricity and performs a pendulum motion under the action of the eccentric sleeve, so that the surface of the crushing wall is sometimes close to the surface of the fixed cone and sometimes away from the surface of the fixed cone, so that the stone is constantly squeezed, broken and impacted in the crushing chamber and crushed.

The motor performs a pendulum motion around a fixed point under the force of the eccentric sleeve through the pulley or coupling, the cone crusher drive shaft and the cone part. This makes the crushing wall of the crushing cone sometimes approach and sometimes leave the surface of the mortar wall fixed on the adjustment sleeve, so that the material is constantly impacted, squeezed and bent in the crushing chamber to achieve crushing.

The crushed material is discharged from the discharge port at the bottom of the crusher under the action of its own weight. The upper cavity of the cone crusher is supported on the spherical bearing at the upper end of the fixed main shaft, and its lower cavity is sleeved on the outside of the eccentric sleeve, and its movement is directly driven by the eccentric sleeve.

When the eccentric sleeve rotates around the main shaft, the moving cone not only rotates with the eccentric sleeve around the center line of the machine, but also rotates around its own axis. The moving cone performs a spatial pendulum motion around the center of its spherical support. The axis of the moving cone intersects with the center line of the main shaft at a fixed point, นั่นคือ, the center point of the spherical surface, and the angle between them is the precession angle.

When the crusher is running, the axis of the moving cone moves in a conical surface relative to the center line of the machine, and the top of the cone is the center of the spherical support, which remains stationary during the movement of the moving cone. ดังนั้น, the movement of the moving cone can be regarded as the rotation of a rigid body around a fixed point, นั่นคือ, the movement of the moving cone is composed of two kinds of rotational motion: precession motion or entrainment motion (the moving cone rotates around the center line of the machine) and rotation motion or relative motion (the moving cone rotates around its own axis).

When the cone crusher is running without load, the rotation of the moving cone is determined by the friction torque of the spherical bearing on the moving cone and the friction torque of the eccentric sleeve on the moving cone. The moving cone rotates in the direction of the larger torque.

ภายใต้สถานการณ์ปกติ, the moving cone rotates along the rotation direction of the eccentric sleeve, and the rotation speed is determined by the difference between the two torques.

The cone crusher controls the rotation of the moving cone between the spherical bearing and the lower bushing of the moving cone. Under load operation, the friction torque of the stone on the cone surface of the moving cone far exceeds the friction torque generated by the eccentric sleeve on the moving cone.
