Limestone grinder is designed by our own engineers and technical workers, basing on industrial mill research of many years and adopting world-leading-powder processing technology. Our machine adopts many advantages from numbers of mill all over the world, such as trapezium’s working surface, flexible connection, roll linked pressure boost, etc. Limestone grinder has overcome the traditional mill’s defect completely in application, capacity, fineness, energy consumption, service life, etc. And it is the ideal substitute of the traditional mill, such as raymond mill, high pressure suspension mill, ball mill, etc. 3-22t/h capacity limestone grinder best feature: 1. The mining processing grinder is featured by vertical structure, small floor area, and strong system. It is an independent production system from the primary process of raw materials to powder making and packaging. 2. The screening rate is up to 99% compared to other mills. 3. The transmission of the machine adopts confined gear box and pulley which guarantees stable transmission and reliable operation. 4. The key parts are all made of high-quality casting and section bars with exquisite craftwork which guarantees the duration of the whole equipment. 5. The electrical system uses centralized control with advanced and reasonable selection and high automatization. 3-22t/h capacity limestone grinder parameters: Name Mtm100 Mtm130 Mtm160 Ring roll number(pcs) 4 5 6 Major diameter of roller(mm) F310x170 F410x210 F440x270 Inner diameter of roller(mm) F950x170 F1280x210 F1600x270 Revolving speed(rmin) 130 103 82 Max feed size(mm)
