Pre-Grinding Mill Features：
1. The granularity of feedstock allowed is large (D≤100mm)
2. The granularity of discharged product is small (D D95≤0.9mm). Discharging efficiency is high.
3. It saves more than 25% of electricity.
4. The process flow is easy. The pre-grinding mill occupies little space and saves on civil engineering investment.
5. The resistant part has a long service life.
6. The pre-grinding mill features simple structure, reliable performance, low management, and operating and maintenance costs.
Pre-Grinding Mill Application：
The pre-grinding mill is used for grinding various nonmetal mine materials.It is the ideal choice for technological updating or production line establishing in cement factories, mines, power plants, etc. The pre-grinding mill can be used for crushing loose iron stone, sand stone, gypsum, blast furnace slag, gangue, lump coal, etc.
