In the production line of aggregate, it is particularly important for the selection of crushing equipment, which is closely related to the level of production efficiency. There are many types of crushing equipment with uneven quality on the market. So, how to choose the right crushing equipment? It needs to understand in-deeply the characteristics of crushed materials and the classification of crushing equipment.
When choosing crushing equipment, it should fully consider the type and hardness of crushed materials, the granularity of incoming and outgoing materials, the output, and the construction site.
Material type and hardness
Different types of materials with different hardness. Therefore, when choosing crushing equipment, it is the primary consideration for the type and hardness of materials.
The hardness of the material is divided into several grades indicates the degree of softness and hardness of the material. It is more difficult to crush for the higher the grade of a harder material. Therefore, it has higher requirements for crushing equipment.
The commonly used Platts hardness rock classification method is to classify rocks according to the firmness coefficient. Such as:
1. Very solid rock f=15~20 (solid granite, limestone, quartz stone, etc.).
2. Hard rock f=8~10 (such as not sturdy granite, firm sandstone, etc.).
3. Medium solid rock f=4~6 (such as ordinary sandstone, iron ore, etc.).
4. Unstable rock f=0.8~3 (such as loess, only 0.3).
Feed and output size
The feeding and discharging granularity determines the model and crushing level of the crushing equipment. In the actual production process, it is usually need secondary crushing or multistage crushing, for the large feed particle size with small discharge particle. On the contrary, if the particle size of the crushed material is small, it only need primary crushing. Common crushing equipment includes jaw crusher, impact crusher, cone crusher, hammer crusher, etc. Customers can choose suitable crushing equipment according to the input and output size of materials and the recommendation of professional engineers.
Capacity
The capacity of materials also plays an important role in the selection of crushing equipment. Usually, the higher the capacity requirements, the larger the size of the crushing equipment selected. For customers themselves, high-quality and high-efficiency aggregate production lines can bring higher benefits. The capacity of crushing equipment on the market varies in size, ranging from tens of tons per hour to hundreds of thousands of tons. Therefore, customers need to reasonably select models and configure the entire aggregate production line according to their actual needs.
Construction site
The actual situation of the construction site directly affects the choice of crushing equipment. Such as the size of the construction site, the specific placement of the crushing equipment, etc., these should be designed according to the customer's choice and specific needs. The design of the entire aggregate production line is different, and the crushing equipment selected is also different.
Customers site in Anhui Province: 150 t/h mobile crushing plant site
Customers site in Sichuan Province: 800 t/h stationary crushing plant site
In summary, the selection of crushing equipment for aggregate production lines is related to the type and hardness of materials, particle size of feed and output materials, capacity and construction site. Therefore, when choosing crushing equipment, it is necessary to understand more professional knowledge, analyze the specific situation in an all-round way, and select a reasonable model, so as to improve production efficiency and obtain more benefits.
