The working principle and seven advantages of energy-saving ball mill for mineral processing

In today's mineral processing plants, energy-saving ball mills for mineral processing can often be seen.Whether it is a metal ore or a non-metallic ore, as long as the useful mineral is in a fine-grained embedded state, it must be ground into a finer particle size in order to separate the useful mineral from the gangue mineral. Crushing equipment alone cannot meet this particle size requirement. The energy-saving ball mill for mineral processing undertakes the grinding operation after crushing, so that the material reaches the expected fineness.So, what is its working principle and what are its significant advantages?

Working principle of energy-saving ball mill for mineral processing

The mineral processing energy-saving ball mill is mainly composed of a cylinder, an end cap, a bearing, and a transmission unit.Its working principle is that when the material enters the mill cylinder through the feeding hollow shaft, the stepped liner or corrugated liner in the warehouse is equipped with steel balls of different specifications.The cylinder rotates under the drive of the motor, generating centrifugal force, which brings the steel ball to a certain height and then falls, causing a heavy blow and grinding effect on the material.After the material reaches the expected fineness in the cylinder, the powder is finally discharged through the discharge grate, thereby completing the entire grinding operation.

For example, an energy-saving ball mill for mineral processing with a hourly output of 100 tons has a diameter of about 2.4m-3.2m.During the work process, the material is repeatedly hit and ground by steel balls of different specifications in the cylinder body, and gradually ground into a powder.This kind of ball mill can adapt to the grinding of various non-flammable and explosive metal or non-metallic materials, especially when grinding gold, iron, copper, feldspar and other materials.

Mineral processing energy-saving ball mill has significant advantages

1. Reduce energy consumption

Mineral processing energy-saving ball mills usually use large double-row spherical roller bearings instead of traditional plain bearings, which greatly reduces friction.Moreover, the starting current of the mineral processing energy-saving ball mill is low, the starting time is short, and the starting is flexible.The normal working current is reduced by 20%-30%. Compared with ordinary ball mills, the power of the original motor is greatly reduced and the installed capacity is reduced, thus achieving the purpose of power saving.After using an energy-saving ball mill in a selected enterprise, the monthly electricity consumption is reduced by thousands of degrees compared to the use of ordinary ball mills, and the annual energy consumption cost is reduced by millions of yuan, greatly reducing production costs.

2. Improve efficiency

The energy-saving ball mill for mineral processing makes full use of the surplus motor capacity and improves the liner structure, which can increase production by 5%-7%.Changing plain bearings to rolling bearings not only has a large carrying capacity and long service life, but also can increase the life of plain bearings by more than 5.

3. Reduce maintenance rate

The energy-saving ball mill for mineral processing adopts glycerin lubrication series to reduce the power of the dilute oil station facilities and the motor, and reduce the fuel saving by 80%-90%.At the same time, the amount of maintenance of the main bearing is reduced, the sanitary environment is improved, and there is no oily pollution.The normal service life of the main bearing is 8-13 years, which greatly reduces maintenance costs and downtime compared to ordinary ball mills.

4. Fully grind the material

The new type of mineral processing energy-saving ball mill adds a drive device on the side, this design allows the horizontal cylinder to rotate more smoothly.In the process of non-stop rolling, the minerals in the cylinder and the abrasive body can fully contact and collide, so as to achieve fuller grinding and make the grinding particle size more uniform.

5. High degree of automation

The improved new type of ball mill will carry out the process flow in stages, adding a small spiral, which can pre-grade coarse-grained stone into the ball mill, and automatically complete the coarse-grained stone anti-sand and cyclone work, ensuring the normal operation of the ball mill system, greatly reducing the difficulty and workload of manual anti-sand operation.In addition, according to the specifications of the material, relevant parameters can be entered through the control panel, so as to automatically control the rotation speed and time of the drum, to achieve automated and high-efficiency ultrafine grinding, reduce labor intensity, and ensure product quality.

6. Strong processing power

The new type of energy-saving ball mill for mineral processing has added a forced ore discharge device at the discharge end and increased the ore discharge port, which has greatly increased the ore discharge volume and significantly improved the production capacity.Compared with traditional ball mills, the processing capacity is increased by 40%.

7. Easy to install

The small mineral processing ball mill with a diameter of less than 2.1 meters is designed as an overall frame, which greatly facilitates civil construction and equipment installation.The whole machine is installed and debugged before leaving the factory. After the equipment arrives at the site, it can be easily installed and put into grinding production as soon as possible.

In short, energy-saving ball mills for mineral processing play an important role in the grinding operations of mineral processing plants. They have the advantages of low energy consumption, high degree of automation, and strong processing capacity. They are often used in mineral processing plants today.
