In the sand aggregate production line, the jaw crusher (jaw break) and the cone crusher (cone break) have significant advantages in energy consumption compared to the hammer crusher (hammer break), mainly reflected in the following aspects:
1. Energy consumption characteristics of jaw crusher
The energy consumption of jaw breakage is relatively low, especially in the coarse crushing stage. According to the national standard (GB/T 25700-2010), the energy consumption index of jaw break ranges from 0.60-2.36 kW·h/m³. Its simple structure, reliable operation, low unit energy consumption, suitable for dealing with various hardness of materials, especially in the medium hardness of materials crushing performance.
2. Energy consumption characteristics of cone crusher
The energy consumption index of cone breakage is also low, and the crushing efficiency is high. According to the relevant standard (GB/T 26965-2011), the energy consumption index of the cone break ranges from 0.55 to 1.75 kW·h/t. It adopts the laminated crushing principle, which can effectively reduce energy consumption, and the finished product has good grain shape and low needle flake content, which is suitable for medium and fine crushing high hardness materials, such as granite, basalt and so on.
3. Energy consumption characteristics of hammer crusher
The energy consumption of hammering is relatively high, especially when dealing with high-hardness materials. According to the national standard (GB/T 33934-2017), the energy consumption index of hammer breakage ranges from 1.10-1.70 kW·h/t. Its crushing ratio is large, but the product grain shape is poor, the amount of fine powder is more, and the wearing parts wear quickly, resulting in an increase in equipment operating costs and energy consumption.
4. Comparison of comprehensive energy consumption
Broken jaw: low energy consumption, suitable for coarse crushing, unit energy consumption in 0.60-2.36kW ·h/m³.
Cone breaking: low energy consumption, high crushing efficiency, unit energy consumption in 0.55-1.75 kW·h/t.
Hammer: high energy consumption, unit energy consumption of 1.10-1.70kW ·h/t, and wear parts fast, high maintenance costs.
Step 5 Summarize
In the sand aggregate production line, jaw breakage and cone breakage have lower energy consumption and higher crushing efficiency than hammer breakage. The jaw break is suitable for coarse crushing, the cone break is suitable for medium and fine crushing, and both perform well in the treatment of high hardness materials, while the hammer break is more suitable for the treatment of medium hardness materials. Therefore, reasonable selection of crushing equipment according to material characteristics and production needs can effectively reduce energy consumption and improve production efficiency.
