Energy-saving ball mill

Production capacity:0.65-615t/h
Feeding size:≤ 25mm
Output size:0.075-0.4
Energy saving ball mill  is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

Introduction

Energy-saving ball mill consist of feeding part, discharging part, rotary part, transmission part (reducer, small gear, motors, electrical control) and other major parts. Hollow shaft is steel castings, and the liner is detachable. Rotary gear is processed by casting hobbing. The cylinder is lined wear-resistant liner plate with good resistance to wear. This machine works stably.

Work Principle:
The main part of energy-saving ball mill is cylinder with small diameter and large length rotating slowly by the transmission device. The material is fed from the cylinder inlet and grinded by the impact of steel ball and ore and self-grinding. Due to the continuously feeding material, the pressure pushes material to the outlet and the grinded material is discharged from the cylinder outlet. In wet grinding, material is taken out; in dry grinding, the material is taken out by air. The grid installed in the outlet of mill is relied for forced discharge. Low pulp surface in cylinder reduces the ore over-grinding, and prevent the steel ball out. Under the same production conditions, production capacity of grid mill is larger than overflow mill’s. Both ends of the cylinder body adopt rolling bearing instead of the sliding bearing, which is more energy-saving.

Advantages:Inquiry > >

  1.Hollow shaft adopts steel casting, and inner plate can be changeable. It is easy to maintain.
  2.Big gear adopts casted rolling teeth, and inside the drum it has wearable liner and good abrasion performance.
  3.Spring energy-saving ball mill operates stably, save consumption, and has high efficiency.
