Toothed roll crusher (especially double-toothed roll crusher) in the field of coal crushing performance is excellent, the comprehensive effect is remarkable, the following is its core advantages and practical application of the analysis of the effect:
1. Crushing efficiency and particle size control
High-efficiency Crushing and Uniform Discharge:
The double-toothed roll crusher applies extrusion, shearing and splitting force to coal through two relatively rotating rolls. With a crushing ratio of up to 5-8, and is able to crush large pieces of raw coal (e.g., 300-600mm) to the target size (e.g., 10-50mm) in one go. The roller spacing can be adjusted hydraulically or mechanically (accuracy ±0.1mm), which achieves the error of discharged particle size ≤3%,. Effectively reduces the phenomenon of over-crushing, and ensures the uniformity of finished coal size.
Dual function of screening and crushing:
Toothed roll structure also plays the role of screening, and materials meeting the requirements of particle size can be directly leaked from the roll gap. Avoiding repeated crushing and further reducing the rate of over-crushing (reducing the amount of coal sludge produced by 40%).
2. Energy consumption and cost-effectiveness
Significant energy saving:
Cleaving and crushing principle has the lowest energy consumption. The unit energy consumption is only 0.8-1.2kWh/t, which is 20%-30% less than the traditional hammer crusher. For example, the energy consumption of a coal mine is reduced by 35% after transformation, and the annual electricity cost is saved about 3 million yuan.
Low maintenance cost:
modular tooth sleeve design supports quick replacement of wear parts (e.g. tooth plate), reducing downtime. Wear-resistant alloy roll face (e.g. chrome-molybdenum alloy) life is 2-3 times longer than ordinary materials, reducing annual maintenance cost by 40%.
3. Material adaptability and environmental performance
High adaptability:
Gangue-containing coal: it can handle raw coal with gangue content ≤30%. And exclude hard impurities through differential rotation and automatic discharge function.
>Wet and sticky coal: anti-sticking roller technology and sealing design effectively solve the blockage problem of high moisture (humidity ≤10%) and sticky coal.
Environmental protection and low noise:
fully sealed structure with dust removal interface, dust emission <10mg/m³. Operating noise ≤85dB (traditional equipment often exceeds 90dB), in line with green production standards.
Double-tooth roller crusher in the coal crushing effect is remarkable: particle size precision control, low energy consumption, adapt to the gangue wet coal, environmental protection and durability, especially suitable for large-scale coal mines or coal processing plants. If you need to deal with high gangue or very hard coal, you can customise the wear-resistant tooth shape (such as flat teeth); the pursuit of automation can be equipped with intelligent control system. The comprehensive performance is better than jaw crusher, hammer crusher and other equipment, which is the ideal choice to improve the efficiency and economic benefits of coal crushing.
