Calcium carbonate is one kind of widely used basic material. Daswell has much experience and projects, with full solution from crushing, to medium size grinding to ultra fine grinding, for different application such as filling compound, paint, ink, paper and so on.
In the last years, Daswell has finished the top class big scale calcium carbonate in China and other countries such as Egypt.Daswell provide the full range solution from crushing, grinding and coating for calcium carbonate.
For crushing ,we supply the professional crushing plant specially for calcium carbonate which will be used then for ball mill plant. Our crusher is going to crush the material to 4mm-5mm, to make sure the better working condition of the ball mill grinding mill then.
We can provide the crushing solution from 20 to 200ton/hour.
By the flow of ultra-fine ball mill＋ultra-fine classifier＋integration of automatic control, we have supplied different capacity ball mill plant of calcium carbonate ultra-fine powder with from 10,000 ton/year to 200,000 ton/year of 3.5-23µm product, to different customers, with the most advanced technology, best quality and performance. You can check the flow chart drawing to learn the working principle. With the primary classifier, you can get 3.5-23µm product.
And if you need produce 2-3µm product, you can choose secondary or third time classifier.
1. Perfect match by the high efficiency grinding and primary or secondary classifier
2. High percentage of fine powder, more specific surface area, round and evenly distributed product shape
3. You can get product size with 3.5-23µm with our design
4. Big productivity to 200,000 ton/year for single plant
5. Very stable working system, with automatic control, very low maintenance cost
The new type coating machine with classifier, is the most advanced coating solution for calcium carbonate now in China.
1. The coating machine and classifier work as a closed recycling system like the ball mill system, at the same time, the coating machine could grind the bigger size which coming back from the classifier to make the coating rate much better
2. Big productivity with low power consumption, closed working system to keep the heat energy inside the system recycling to save power
3. With less stearic acid consumption, to get better result, the coating rate could reach 99%
4. All closed working system, no dust flying out to protect the environment
5. The core rotating wheel material coming from Germany (the line speed could reach 115m/s), with very high quality and wear-resisting
