Ball mill grinder is the key equipment for grinding materials after crushing and screening. A certain number of grinding balls are loaded into the ball mill cylinder as the grinding medium.
It is widely used in mineral processing, building materials, chemical industry and other industries. It can be divided into dry grinding and wet grinding. According to the different ways of ore discharge, it can be divided into grate type and overflow type.
Ball Mill Grinder Working principle
The materials enter the first chamber of the ball mill through the feeding hollow spiral and uniformly. There are stepped liners or corrugated liners in the chamber, which are filled with steel balls in various sizes. The cylinder rotation generates centrifugal force to bring the steel balls to a certain height and then fall down, causing heavy impact and grinding on the materials. After the materials reach the rough size after grinding in the first chamber, they enter the second chamber through a single-layer partition board. The second chamber is lined with a flat liner, and steel balls are inside to further grinding. The powder is discharged through the discharge grate to complete the grinding operation.
Ball Mill Grinder Structure
The ball mill content feeding device, discharge device, cylinder, transmission device (motor, reducer, control system, pinion), girth gear, etc.
ball mill Grinding media
There are several kinds of ball mill grinding media: Forged steel ball, High alumina ball, cylpeb. Forged steel ball is the most common type grinding media, and high alumina ball is widely used for free-iron-pollution powder grinding.
Ball mill liner
Most popular liner for ball mill is the high manganese liner. For ceramic industry, the high manganese liner will take iron pollution to the material, thus the alumina liner is an ideal choice. In mining field, rubber liner is used to avoid acid-base liquid corrosion to the liner.

SMAT Ball Mill advantages
With 33 years of experience in ball mill manufacturing, SMAT always provide you cost efficient but high performance ball mill grinding solutions.
1. Advanced Ball Mill Technology
For example, the ball mill rotate speed designing is very important for ball mill running. In the following figures, Figure b is ideal speed, the grinding media mixed with material can be lifted to a certain height then fall down, this will give biggest grinding strength.
If the speed too low, it’s just like Figure a, the grinding media mixed with material fall down before they are lifted, thus the grinding strength will be very low, which lead to low grinding capacity.
While, if the speed very high, it will be like figure c, grinding media mixed with material will rotate along with the ball mill cylinder. No grinding during the ball mill running.
2.Powerful Manufacturing Ability And Facility.
Qualified ball mill processing is inseparable from perfect processing capabilities and the required processing equipment. We have complete processing equipment, such as Automatically cutting Machine, Rolling Machine, Automatic Arc-submerging Welder, Edge Planer, Gear Milling Machine, Heavy Numerical Control Double – Column Vertical Lathe, etc.
3.Proper Project Designing
The SMAT design team will design and select a suitable ball mill according to the specific requirements of your project. For example, as we all know, in the case of the same length, the larger the diameter of the ball mill, the greater the processing capacity. In the case of the same diameter, the larger the length, the finer the output.
Choosing the right size ball mill according to the project requirements plays a vital role in the success or failure of a project.
4.Reliable After-sales Service
All SMAT users naturally enjoy a minimum one-year equipment warranty on all equipment. During the warranty period, SMAT will respond to your related complaints or other requirements within 24 hours.
No matter which country or region you are in the world, SMAT engineers will arrive at the site according to your needs to guide you in installation and commissioning, and assist in training your operators.
5. Fast Delivery
For common model, like Ф900×1800, Ф1500×4500, Ф1830×7000 and other models, we always have machine in stock, so that we could deliver immediately to client for urgent project requirements.
Q:What is the main difference of wet ball mill from dry ball mill?
The wet ball mill is similar to the dry ball mill, but there are differences. The wet ball mill needs to add an appropriate amount of water or absolute ethanol during the grinding process, which means that there are certain requirements for the concentration of grinding. The amount of water is determined by the nature of the material. Qualified materials are discharged out of the cylinder through the discharge part, and unqualified materials are returned to the wet ball mill again for re-grinding.
Q:How to choose suitable ball mill?
We have engineer team specially for project solution designing, they will calculate based on your project requirement, such as the hourly capacity, input and output size, etc.
Please contact us for free project designing.
