Typical characteristics of grate ball mill

2025.06.17

1. The forced discharge structure design is different from the overflow ball mill, and the grate plate device constitutes its most significant feature. The structure consists of several fan-shaped perforated plates, and the graded discharge of the grinding products is achieved by adjusting the aperture (usually controlled at 8-20mm). This design enables the equipment to maintain a slurry filling rate of about 20-30%, effectively avoiding over-grinding, and is particularly suitable for coarse gri...

0918 Gold Mine Ball Mill Parameters and Application Introduction

2025.06.16

1. Core parameter configuration of 0918 gold mine ball mill The 0918 ball mill has a barrel diameter of 900mm and a length of 1800mm. It uses JM series manganese steel liners and is equipped with a 45kW explosion-proof motor as standard. The speed is set to 76% of the critical speed (about 28r/min). In terms of loading capacity, the steel ball filling rate is 35%-40%, the processing capacity is 0.8-2t/h (depending on the hardness of the ore), the feed particle size is ≤25mm, and the discharg...

What are the differences between dry magnetic separator and wet magnetic separator?

2025.06.13

Technical comparison between dry magnetic separator and wet magnetic separator 1. Sorting medium and working principle Dry magnetic separator uses air as the sorting medium and directly acts on dry minerals through a high-intensity magnetic field. Its core advantage is that it does not require water, which is particularly suitable for arid areas or water-sensitive material processing. Typical equipment such as permanent magnetic drum dry separators can have a magnetic field strength of...
