There are many ways to break stones, and they are used for different purposes.The main methods are extrusion crushing, impact crushing, splitting method, grinding and peeling method, etc. In rock crushing, extrusion crushing and impact crushing are mainly used for rough crushing, fine crushing, and sand-making processing of stones; let’s introduce it in detail next.
What are the ways in which stones are broken?
1. Extrusion crushing : The material mainly achieves the crushing effect through the slowly increasing pressure between the two working surfaces.
2. Splitting and crushing: This type of equipment is mainly used to squeeze the ore with a sharp edge and a sheet with a sharp edge, and the ore will be broken by splitting in the direction of the pressure line.
3. Breaking and crushing: Large pieces of ore are bent and broken into small pieces.
4. Grinding and crushing: There is relative movement between the ore and the moving working surface and it is subjected to a certain amount of pressure and shear. When the shear stress reaches a certain level, the ore will be crushed.
5. Impact crushing : The material is broken by a greater impact force.This crushing method is highly efficient, with a large crushing ratio and relatively little energy consumption.
Common methods of stone crushing
There are two commonly used crushing methods of mining equipment on the market: extrusion crushing and impact crushing.1.Extrusion crushing is mainly carried out by jaw crushers and cone crushers, while impact crushing is completed by impact crushers and impact crushers.Next, these four crushers will be introduced in detail:
Jaw crusher is mainly composed of frame body components, jaw plate mounting components, moving jaw components, wheel components, adjustment device components, transmission tensioning components, foot mounting components, feed hopper (optional) and protective cover (optional) and other parts.Usually driven by a motor as the source of power, the motor inputs power to the pulley through the SPC belt, and the pulley drives the eccentric shaft to rotate to drive the moving jaw body to swing back and forth up and down.When the moving jaw plate moves close to the fixed jaw plate, the volume of the crushing chamber decreases, and the material in the crushing chamber is squeezed or broken. When the moving jaw plate moves away from the fixed jaw plate, the volume of the crushing chamber becomes larger, and the small pieces of material that are broken in the crushing chamber are discharged from the discharge port for continuous circular movement to achieve crushing operations.
Cone crusher is a high-performance crusher designed to absorb modern technology and combine the properties of Chinese metal materials. The cone breaking cone rotates under the action of an eccentric sleeve, driving the crushing wall to squeeze and rub the material between the mortar wall and the mortar wall. According to the lamination theory, the material is subjected to forces in multiple directions, broken according to its own texture and polished to form stable stone particles, which fall from the gap between the crushing wall and the pendulum that meets the discharge requirements, and the rest of the material continues to be broken until it meets the requirements.
Impact crusher is a kind of crushing machinery that uses impact energy to crush materials.When working, the motor drives the rotor to rotate at high speed. When the material enters the zone of action of the plate hammer, it is broken by the high-speed impact of the plate hammer. The broken material is thrown in the tangent direction to the counterattack plate mounted above the rotor and broken again, and then bounced back from the counterattack plate to the zone of action of the plate hammer and broken again.This process is repeated until the material is broken to the desired particle size and discharged from the discharge port.Adjusting the gap between the counterattack frame and the rotor can achieve the purpose of changing the material particle size and material shape.
Vertical shaft impact crusher absorbs many years of R&D experience and technical concepts, adopts a brand new four-port impeller design structure and a special sealing structure to prevent oil leakage from the bearing cylinder and other processes, the motor drives the bearing cylinder to drive part of the spindle for high-speed rotation, and the rotor rotates at high speed with the spindle. The material entering the impeller is accelerated by the impeller and sprayed into the crushing chamber. The material formed in the crushing chamber collides with each other and grinds, converting the kinetic energy obtained after the material is accelerated into the energy required for crushing or shaping the material. The material that circulates multiple times in the crushing chamber is under the action of the surrounding gas eddy current. After multiple crushing and shaping, the continuous crushing and shaping of the material is realized, and the required finished material is discharged from the lower part of the body. This crushing method is “Stone hitting stone”. This mode is mainly used for the shaping and crushing of stone materials. In addition, this equipment is also equipped with “Stone hitting iron” crushing method, which is different from stone hitting stone. After the material is ejected from the rotor, it collides with the counterattack block installed in the crushing chamber, which accelerates the material to obtain energy and converts it into the energy required for collision and crushing with the counterattack block. After the impact, the material is discharged directly from the lower part of the body, which cannot be achieved in the crushing chamber. Multiple cycles of crushing, this crushing method is mainly suitable for crushing-based (for the purpose of providing a large crushing ratio) workplaces.
