In June 2016, a customer in Yixing cooperated with us on the milling equipment in the ceramic plate plant. We completed the delivery within a month and completed the installation work in 15 days. Because of our mature grinding technology and efficiency of rapid installation, the customers cooperated with us again in September for the flour milling process in the second ceramic plate plant.
Ceramic milling process can be divided into two kinds: wet and dry. At present, the wet method is commonly used.
1) Wet Production plant:
The equipment is a ball mill and a dryer. The main process is to transport ceramic raw materials to the ball mill, and then add 30~40% of water to grind it into mud, then dry it in the drying tower to make a powder of 7% water content. The drying time is long, the drying is slow and the output is low.
2) Dry Production Plant:
The equipment is a vertical mill (or a T mill) and a granulator. The main process is to grind the ceramic raw materials directly with the mill, then use the dry granulator to do the humidifying granulation, and then use the fluidized bed for drying to control the moisture content of the powder at 7%, and then enter the grinding process.The drying time is short, the drying is quick, and the output is high.
Compared to wet method, the benefits of dry method are: the energy consumption of thermal energy is saved more than 80%, the electricity consumption is saved more than 35%, the emission is reduced more than 80%, the water reducer, ballstone and other additives are also saved. In addition, wet method is gradually eliminated under the pressure of environmental protection. So the plant we designed for the customers uses the dry production process.
1) Dry milling process replaces two largest energy consumption links in wet milling process, “Ball abrasive slurry” and “spray granulation”. It has obvious advantages of energy saving and emission reduction, and is the inevitable direction of ceramic industry's healthy development in the future.
2) We fully respect the principle of maximizing the interests of customers, so we use MTW European trapezium mill instead of vertical mill to reduce customer’s investment costs and have good economic returns.
3) Due to the large amount of silicon in the raw material, the equipment has a high degree of wear. As for the characteristics of the material, we make a special treatment when we manufacture the equipment.
4) Due to the lack of customer’s experience in mill operations, as long as the mill operation has problems, our staff will be rushed to the customer's site as soon as possible to help customers solve problems. The efficient and fast after-sales service is an important reason for us to win the second cooperation with customers.
