Case Report2- Carbon Black Powdering from Waste Tires in the United States
In July 2024, one of our American customers started construction. At present, the infrastructure has been basically completed and the trial-running is ready for early November. This is a waste tire cracking and carbon black extraction project served by our company, and the finished product is used for drying and granulation. The customer requires an annual output of about 10,000 tons, and the finished product particle size is D99 400-600 mesh. The mill equipped by our company is MW1080 micro powder mill. There are no difficulties in the project process. It is mainly based on the special pipeline design and layout according to the customer's on-site conditions. The customer is very satisfied and looks forward to the trial-running.
Waste tire pyrolysis to recover carbon black
Waste tires are first cleaned, then sliced or crushed, and then magnetically separated to separate waste steel wire. The remaining materials are sent to the pyrolysis furnace after drying and preheating. Under the protection of inert gases such as water vapor or nitrogen, thermal decomposition reactions are carried out. Due to the differences in the target substances, the processes are also different.
The MW series ring roller micro powder mill, also known as the medium-speed micro powder mill and ring roller mill, is a processing equipment specially developed for the production of ultrafine powder and micro powder by Liming Heavy Industry based on nearly 40 years of mill R&D and manufacturing experience, modern powder grinding technology, and the development trend and demand of the mill market at home and abroad after many investigations, research and tests.
1. Safe and reliable operation
There are no rolling bearings and screws in the grinding chamber, which avoids the problem of bearing wear and screw loosening and damage to the equipment.
2. Advanced and stable transmission
The reducer transmission device is adopted, which is more stable and efficient than the traditional belt drive.
3. Accurate particle size control
Adopting new high-efficiency cage powder selector, frequency conversion control, convenient particle size adjustment, precise cutting particle size, the final fineness of the finished product can reach D97≤5um at one time.
4. Low wear and excellent quality
High-quality wear-resistant parts, adopting material layer grinding mechanism, small wear, effectively reducing pollution during material processing, and ensuring the quality of the finished product.
5. Low power consumption and more energy-saving
Low-stress multi-roller material layer grinding, reasonably optimized roller grinding curve and online instant powder selection determine the low power consumption of equipment grinding and more energy-saving.
6. Clean and environmentally friendly
The equipment adopts high-efficiency pulse dust collector, equipped with silencer and silencer room, which reduces dust and noise pollution and meets the latest national environmental protection standards.
