In the primary crushing, it is very important to choose the right crusher. Here are several types of crushers and their characteristics recommended for primary crushing:
Features of primary crushing equipment - jaw crusher
• Jaw crusher, also known as a lower jaw crusher or jaw crusher, is one of the most common crushers.
• It crushes materials into particles of different sizes through the relative movement of the movable jaw and the static jaw.
• Jaw crusher has the characteristics of a simple structure, stable operation and convenient maintenance.
• Large crushing ratio and uniform product particle size.
Suitable for small and medium-sized crushing occasions, especially when handling large pieces of material.
•Advantages of primary crushing equipment - jaw crusher:
• Strong crushing capacity and can handle larger materials.
• Simple structure, easy to operate and maintain.
Disadvantages of primary crushing equipment - jaw crusher:
• Relatively low production capacity and low crushing efficiency.
• Easily affected by material hardness.
Primary Crushing Equipment - Cone Crusher Features:
Cone crusher is suitable for materials with higher hardness, such as limestone, granite, etc. It has the characteristics of high production capacity, stable operation, and easy maintenance.
The finished product has uniform particle size, suitable for medium and fine particle crushing.
• Primary Crushing Equipment - Cone Crusher Advantages:
• High crushing efficiency, suitable for high hardness materials.
• Precise particle size control of finished products.
• Primary Crushing Equipment - Cone Crusher Disadvantages:
• Cannot crush materials with high water content.
• Susceptible to steel ball wear.
Primary Crushing Equipment - Hammer Crusher Features:
• Combines two-stage crushing into one, can handle materials with lower hardness
• Simple structure and low cost.
• Primary Crushing Equipment - Hammer Crusher Advantages:
• Easy to operate and maintain.
• High crushing ratio.
Primary Crushing Equipment - Hammer Crusher Disadvantages:
• Hard materials are prone to wear and clogging.
• The hammer head needs to be replaced frequently.
• Summary and recommendation:
For the initial crushing, the jaw crusher is the first choice because of its simple structure, stable operation, easy maintenance, and strong ability to handle large materials. It is suitable for small and medium-sized crushing occasions and is widely used in industries such as gold mining, construction, and highways. Although cone crushers and heavy hammer crushers also have their own advantages, in the initial crushing stage, the jaw crusher is more recommended because of its superior comprehensive performance.
