Jaw crusher, impact crusher and cone crusher are three commonly used crushers, which have different characteristics and scope of application in crushing production.This article will introduce the differences between these three crushers and how to choose a suitable crusher.
What is the difference between jaw crusher, impact crusher and cone crusher?
Structure and working principle
(1) Jaw crusher: The jaw crusher consists of fixed jaw plate, movable jaw plate, eccentric shaft, bearing and other main components.Mainly through the relative movement of the movable jaw plate and the fixed jaw plate, the material entering the crushing chamber is clamped, and then by means of the rotation of the eccentric shaft, the movable jaw plate is moved to break the material into the desired particle size.
(2) Counterattack crusher: The counterattack crusher is mainly composed of counterattack plate, counterattack hammer, fixed plate hammer, adjustment plate, chassis and other parts.After the material enters the crushing chamber, the counterattack plate and the counterattack hammer crush the material at high speed, and then the broken material is discharged through the adjustment plate.
(3) Cone crusher: Cone crusher is mainly composed of fixed cone sleeves, movable cone heads, eccentric shafts, bowl-shaped bearings and other parts.After the material enters the crushing chamber, the material is broken into the required particle size by the rotational movement of the cone head and the friction of the inner lining plate fixing the cone sleeve.
Crushing method
(1) Jaw crusher: it adopts extrusion and bending crushing methods, which are suitable for crushing materials with high compressive strength.
(2) Impact crusher: adopts high-speed impact crushing method, which is suitable for crushing materials with small compressive strength.
(3) Cone crusher: Adopts compression crushing method, which is suitable for crushing materials with high compressive strength.
Scope of application
(1) Jaw crusher: It is widely used in material crushing in construction, mining, chemical industry, road and other industries.
(2) Impact crusher: it is suitable for crushing materials in construction, mining, chemical industry, roads and other industries, especially for crushing harder materials such as limestone and granite.
(3) Cone crusher: It is widely used in crushing materials in construction, mining, chemical industry, roads and other industries, especially for crushing abrasive, cement, metal mines and other harder materials.
In crushing production, how should I choose a suitable crusher?
- Material characteristics: According to the hardness, compressive strength, humidity, particle size and other characteristics of the material, choose a suitable crusher.
- Production capacity: According to production needs, select the corresponding crusher to ensure production efficiency.
- Particle size requirements: According to the final particle size requirements of the material, choose a suitable crusher.
- Crushing method: According to the crushing method of the material, select the corresponding crusher.
- Equipment reliability: choose equipment with high reliability to reduce failure rates and maintenance costs.
- Economic benefits: Consider equipment investment, operating costs, maintenance costs and other factors comprehensively, and choose a crusher with high economic benefits.
Jaw crushers, impact crushers and cone crushers each have their own characteristics and scope of use. When choosing, they should be evaluated and selected in accordance with the actual situation.
