φ 5.8 × 8.7m wet overflow type ball mill for mining (edge drive)

Introduction

Pengfei group has developed large-scale autogenous mill, semi autogenous mill, overflow mill and air swept mill by increasing cooperation with scientific research institutions for many years. Widely used in metallurgy, mining, cement, power and other industries. "Pengfei" brand ball mill takes full account of the operating conditions of users, improves the internal conditions of the mill continuously according to the partition plate and discharge grate plate, provides new liner plate as required, adjusts the mill speed, optimizes the gear design and bearing pad lubrication parameters, increases the stability and service life of the mill, and improves the grinding efficiency.
