MQY ball mill has the characteristics of improving grinding efficiency and reducing energy consumption at the same time

The letter “Y” in the MQY ball mill represents the overflow type, so it refers to the overflow type ball mill.MQY ball mill is widely used in building materials, mineral processing and other industries. It is particularly suitable for fine grinding operations. It is generally used for two-stage grinding in two-stage grinding operations, and can grind ore particle size to -325 mesh or even finer.So what types of MQY ball mills are there?What is the application field and product structure?This article will take you to understand this ball mill.

1. MQY ball mill type

We can divide the types of MQY ball mills into ordinary overflow ball mills and energy-saving overflow ball mills.

Ordinary overflow ball mill

Overflow type ball mill products have fine particle size, generally less than 0.2mm, which is more suitable for concentrate re-grinding operations, and is commonly used for two-stage grinding with fine fineness.The ore discharge is caused by the slurry itself being higher than the lower edge of the hollow journal bushing and overflowing.

For example, the wet overflow ball mill MQY 0918 produced by XKJ GROUP has a production capacity of 0.17-170t/h.The cylinder of the ball mill is welded with steel plates with a thickness of 15-36mm, and flanges made of cast steel are welded at both ends of the cylinder, and the end caps and flanges are connected together with bolts.There are 1-2 individual holes in the cylinder body for maintenance and replacement of the liner.The advantages and characteristics are jacking device, which is easy to overhaul; static and dynamic bearings, which operate smoothly and reliably; slow transmission, which is easy to overhaul and start; oil mist lubrication device, which ensures reliable lubrication of large and small gears; flexible start of gas clutch.

Energy-saving overflow ball mill

Compared with ordinary ball mills, the energy consumption of this energy-saving overflow ball mill can be reduced by about 30% and the motor power consumption can be reduced by 15-25%.

For example, the energy-saving ball mill produced by XKJ GROUP can reduce the motor power by 20-35%, save about 95% of cooling water, and save more than 35% of the overall energy of the entire equipment; the starting current is low, the starting time is short, the starting is flexible, and the normal working current is reduced by 20%-30%; make full use of the surplus motor capacity and improve the liner structure, which can increase production by 5%-7%; change the plain bearing to a rolling bearing, which has a large carrying capacity, but the life of the plain bearing is increased by more than 5%.

XKJ GROUP also has wet energy-saving overflow ball mills based on this, such as MQYg 1224.The energy-saving effect is even more significant, reducing energy consumption by about 20-30%.In the naming of the model, only “g” is added to the type to indicate that it is an energy-saving type.

2. The application field of MQY ball mill

In the mineral processing industry, MQY ball mills grind various ores to fully separate the useful minerals in the ores from gangue minerals and improve the mineral processing efficiency.For example, in the mineral processing of gold mines, large pieces of gold ore are first broken into smaller particles by crushing equipment, and then ground into fineness that meets the requirements by a ball mill to prepare for subsequent sorting operations.In the metallurgical industry, MQY ball mills can grind ore into a fine powder to facilitate the subsequent smelting process.
