Grid Type Ball Mill

Grid Type Ball Mill

【Introduction】:
A traditional ball mill with discharging grid
【Diameter】:
900mm~4500mm
【Improvement】:
Wet type grid ball mill is lined with Xinhai wear-resistant rubber sheet with excellent wear resistance, long service life and convenient maintenance

【Advantages】

Jack-up device, easy maintenance;

The hydrostatic and hydrodynamic bearings ensure the smooth operation;

Low speed transmission is easy for starting and maintenance;

The oil-mist lubrication device guarantees reliable performance of bearings;

The gas clutch adopts the flexible start-up model

【Product Structure】

The main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow.

【Successful case】

wet-grid-ball-mill

In the iron ore dressing plant in Yunnan, ore hardness, the ore has a high hardness, and the client requires small grinding particle size. In order to avoid over crushing, the client selected Xinhai wet grid type ball mill in grinding process. The grinding medium are steel ball and ore itself, the grinding efficiency is high, it also adopts the hydrostatic and hydrodynamic bearings, which ensures the smooth operation and easy to grinding. At the same time, the oil-mist lubrication device guarantees reliable performance of bearings, improving the production efficiency. The mineral syrup liquid is low, and discharge timely, which reduce energy consumption and achieve the best results.
