ISO9001:2008 Pre-Grinding Mill Introduction
Our company integrates the technology concerning pre-grinding mill at home and abroad and improves the main technical specifications to successfully design and manufacture the YM series of pre-grinding mill. 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. It has the features of high crushing ratio, low energy consumption, smooth operation, simple structure, convenient maintenance etc. The hammerhead uses a hinge structure making it convenient for replacement. Both the hammerhead and scaleboard are manufactured with highly wear-resistant alloy and feature high strength, high corrosion resistance and long service life.

ISO9001:2008 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.
