How to choose secondary crushing equipment?
Introduction
Crushing equipment has a crucial role in the configuration of stone crusher plant. The reasonable equipment configuration is related to the investment, production, product quality of the whole production line.
For secondary crushing equipment, symons cone crusher and impact crusher are both commonly used equipment, so what is the difference and how to choose between the two equipment? This article analyzes the difference between symons cone crusher and impact crusher from 8 aspects.
1. Different structures
Both the symons cone crusher and impact crusher are for secondary crushing, it is easy to distinguish from the crushing principle and appearance.
2. Different working principle
The impact crusher adopts the principle of impact crushing, where the material is crushed by repeated impacts between the hammer bars and the impact plates.
The cone crusher adopts a combination of crushing, shearing and grinding, and the mantle constantly moves toward the bowl liner, squeezing the material in the crushing chamber to crush them.
3. Different applications
Both Symons cone crusher and impact crusher can be used as secondary crushing equipment, but they are for different hardness of the materials.
Symons cone crusher is mainly used to crush hard materials, such as granite, basalt, tuff, river pebbles, etc., while impact crusher is used to crush soft and medium hardness materials also brittle materials, such as limestone.
4. Different discharge size
The two types of crushers crush materials with different discharge sizes. Generally speaking, the short head cavity symons cone crusher crushes finer material than the impact crusher.
In the actual production process, the symons cone crusher is more used in the mineral processing process, while the impact crusher is more used in the building materials and construction projects.
5. Different granularity of finished products
The impact crusher has good granularity, less angularity in the finished product and more powder; the symons cone crusher has more needle-like granularity in the finished product.
6. Different process capacity
Compared with impact crushers, symons cone crushers have low energy consumption, high production capacity and stable operation, so cone crushers are commonly used in large scale and high production lines.
7. Different investment
The price of symons cone crusher is more expensive than impact crusher, but its wearing parts have longer life, avoiding the trouble of replacing wear parts frequently, and in the long run, symons cone crusher is more cost-effective than impact crusher.
Impact crusher has lower initial purchase cost but higher maintenance cost later; while symons cone crusher has higher initial cost but lower maintenance cost later.
8. Different degree of environmental protection
The noise and dust of the impact crusher is higher, while the symons cone crusher is relatively small and more environmental friendly.
In summary, impact crushers and symons cone crushers have their own advantages and disadvantages.
In actual production, we need to make a reasonable selection according to the nature of the material, feed and discharge size, process capacity, investment cost, maintenance, operation stability, etc.
