Steel slag and aluminum slag ball mill is a grinding equipment specially used for processing steel slag, aluminum slag, and other metallurgical waste slag. Steel slag can be used to prepare mineral admixture, road base material, etc. Aluminum slag is widely used to produce alumina, chemicals, recycled metal aluminum, etc. Steel slag and aluminum slag ball mill grind steel slag and aluminum slag into fine powder through grinding process, which is used to produce building materials, concrete additives, or other high-value-added materials.

Steel slag and aluminum slag ball mills adopt optimized transmission systems and liner designs to improve grinding efficiency and reduce energy consumption at the same time. It is capable of processing metallurgical slag of various hardnesses, including steel slag, aluminum slag, electric furnace slag, and so on. The steel slag and aluminum slag ball mill is well closed during operation, reducing dust spillage, and can be matched with dust removal equipment to realize green production. It can adjust the fineness of powder according to the need, usually ranging from 80-325 mesh or even higher. Steel slag and aluminum slag ball mill cylinders and liners adopt wear-resistant materials, which are suitable for long-term grinding of steel slag, aluminum slag, and other high-hardness materials. Comprehensively speaking, steel slag and aluminum slag ball mills have the features of high efficiency and energy saving, strong applicability, superior environmental protection performance, adjustable finished product particle size, strong wear resistance, and so on.

Steel and Aluminum Slag Ball Mill

Steel and aluminum slag ball mill is commonly used in

Building materials industry: production of mineral admixture, used in cement and concrete.

Metallurgical industry: to recover useful metals (such as aluminum, and iron).

Environmental protection industry: steel slag, aluminum slag resource utilization, reduce solid waste emissions.

Steel Slag and Aluminum Slag Ball Mill Discharge

Factors affect the discharge quality of steel slag and aluminum slag ball mill

The particle size of the material to be ground: The particle size of the material to be ground directly affects the output and quality of the ball mill. Small particle size, mill output, high quality, low power consumption; large particle size, mill output, low quality, high power consumption.

Grindability of the material: The grind-ability of the material refers to the degree of difficulty of the material to be ground, usually with the crushing power index Wi (kwh/t) to indicate. The smaller the value is, the easier the material is to grind, and the opposite is difficult to grind.

The moisture of the material to be ground: For the dry grinding method, the moisture of the material to be ground has a great influence on the output and quality of the mill. Excessive moisture will lead to full grinding or paste grinding, reducing grinding efficiency, and thus affecting the mill output.

The temperature of the material to be ground: The high temperature of the material to be ground will affect the grinding efficiency, lead to the sticky ball phenomenon, reduce the grinding efficiency, and also affect the long-term safe operation of the mill.

Requirement of fineness of the material to be milled: The higher the requirement of fineness of the material to be milled, the lower the output. Choosing the right fineness of the product is an important factor in improving the output and quality of the mill.

Grinding process flow: The closed circuit process is 15-20% higher than the open circuit process. Choosing the proper powder selection efficiency and circulating load rate is an important factor in improving the mill output.

Powder selecting efficiency: The efficiency of the powder selector has a significant impact on the output of the mill. The higher the efficiency of the powder selector, the higher the grinding efficiency of the mill.

Circulating load rate: The circulating load rate refers to the ratio of the powder return volume of the powder selector to the finished product volume. Appropriately increasing the cyclic loading rate can improve the milling efficiency, but too high a cyclic loading rate will reduce the milling efficiency.

Steel and Aluminum Slag Ball Mill

Steel & Aluminum Slag Ball Mill Grinding Fast Discharge

Steel and aluminum slag ball mills in use for a period of time, often encounter some small faults, these small faults need to be timely and symptomatic solutions, to prevent the production of steel and aluminum slag ball mills paralyzed. For example, sometimes the discharge of the ball mill will become too fast, which needs to be dealt with in time. The following will introduce the reasons and solutions for the ball mill discharge too fast.

Reasons for the fast discharging of ball mill

Ball mill grinding media is too fine: Ball mill grinding media is too fine will lead to material discharging speed being too fast, because the grinding media is too fine will increase the surface area of the material, thus reducing the fluidity of the material.

Ball mill speed is too high: Ball mill speed is too high will also lead to the material discharging speed being too fast, because the high speed will lead to the rolling speed of the material in the mill being too fast, thus affecting the fluidity of the material.

Insufficient filling amount of grinding media: Insufficient filling amount of grinding media is also one of the reasons that lead to fast discharging speed of the ball mill because the insufficient filling amount of grinding media will lead to fast-rolling speed of materials in the mill, thus affecting the fluidity of materials. 

How to solve ball mill discharging fast?

Adjust the particle size of grinding media: Adjusting the particle size of grinding media can reduce the surface area of the material, thus improving the fluidity of the material and slowing down the material discharge speed.

Adjust the speed of the ball mill: Adjusting the speed of the ball mill can make the rolling speed of the material in the mill slow down, thus affecting the fluidity of the material, sand lowering the material discharge rate.

Increase the filling amount of grinding media: Increasing the filling amount of grinding media can make the rolling speed of the material in the mill slow down, thus affecting the fluidity of the material and slowing down the material discharging speed.

Regular cleaning of the ball mill: Regular cleaning of the ball mill can remove the residue of the grinding media and materials, thus improving the fluidity of the material and slowing down the material discharge rate.
