Aluminum ash ball mill picture
Working principle of aluminum ash ball mill
The material is uniformly fed into the first compartment of the mill through the feeding device and the hollow shaft screw. The compartment is equipped with stepped or corrugated lining plates and contains steel balls of different specifications. The rotation of the cylinder generates centrifugal force, which brings the steel balls to a certain height and then drops them, causing heavy impact and grinding on the material. After the material reaches rough grinding in the first warehouse, it enters the second warehouse through a single-layer partition plate. The warehouse is lined with a flat lining plate and contains steel balls for further grinding of the material. The powdered material is discharged through the discharge grate to complete the grinding operation.

Advantages of aluminum ash ball mill
1. Energy saving
Traditional ball mills use bearing shells as the main bearings.
2. Increase production
The inner diameter of the feeding port of the old-fashioned ball mill is 150mm, with a single spiral and natural feeding. Due to the light density of aluminum ash and large fluctuations in raw material particle size, the equipment is operating at half load. The Jinyang aluminum ash ball mill has increased the inner diameter of the feed inlet from a diameter of 900 to a diameter of 210mm, and from a diameter of 1200 to a diameter of 300. The double helix is used for forced feeding, and the proportion of steel balls is scientifically adjusted to increase the speed, thus achieving the goal of increasing production. The diameter of the 900 ball mill has been increased from 0.3-0.5T/hour to 0.6-1T/hour. The diameter of the 1200 ball mill has been increased from 0.5-1t/hour to 1.5-2.2t/hour.
3. Small dust
The dedicated outlet is equipped with a dust collection hood, greatly reducing dust.
4. Less investment
Installing a cylindrical screen with tapping function at the outlet of the ball mill saves one linear vibrating screen compared to traditional methods, which can save about 10000 investment and reduce operating costs.
5. Good spindle performance and high processing capacity
The main bearing adopts a large-diameter double row self-aligning rod bearing, replacing the original sliding bearing, reducing friction, lowering energy consumption, and making the mill easy to start.
The end cover structure of the ordinary grinder is retained, with a large-diameter inlet and outlet and a large processing capacity.
6. Simple structure and smooth operation
The feeders are divided into two types: joint feeders and drum feeders, with a simple structure and separate installation.
There is no inertial impact, the equipment runs smoothly, and the downtime and maintenance time of the mill are reduced, improving efficiency.
7. Reduce the workload of workers
Cooperating with automatic cleaning is beneficial for cleaning residues inside the mill. The feeder is equipped with a clearing device.

Several methods for reducing the noise control of aluminum ash ball mill
1. Reduce working hours and labor processes, while operators should also take protective measures such as earplugs, noise proof cotton, helmets, etc.
2. Reasonably arrange or adjust the installation layout, replace all the guardrails on one side of the aluminum ash ball mill with movable soundproof screens. This not only absorbs the noise of the aluminum ash ball mill, but also plays a role in sound insulation. This not only absorbs the noise of the ball mill, but also provides sound insulation to protect maintenance personnel. In addition, the duty room can be converted into a soundproof room and soundproof panels can be installed around it.
3. Strengthen the maintenance and management of aluminum ash equipment. When the aluminum ash sorting machine operates with faults due to long-term disrepair, the noise will increase. Therefore, it is necessary to do a good job in the daily maintenance and repair of the aluminum ash ball mill.

Aluminum ash treatment process
It can be divided into hot ash treatment process and cold ash treatment process, mainly used for the recycling and utilization of metals in non-ferrous metal smelting waste such as aluminum ash, aluminum slag, lead ash, and lead slag.
Hot ash treatment process
1. Processing less than 1 ton per day, suitable for processing near the furnace and surrounding workshops without special requirements;
2. Processing 1-5 tons of aluminum ash per day, with average dust removal effect. Aluminum ash can be centrally processed near the furnace or in a nearby workshop;
3. Daily processing of 5-40 tons of aluminum ash, forklift transportation of ash, fully enclosed, with a cold ash mixing system, rapid cooling mechanism for rapid cooling, screening, and then returning to the furnace. This method of processing is relatively clean and thorough, with a residual aluminum content of 2% -5%. It is equipped with bag dust removal and does not include dust removal, making it suitable for centralized processing in large aluminum plants.
Cold ash treatment process
Currently, in China, cold ash is generally melted using a mill, vibrating screen, crucible, and repeated twisting and screening to obtain residual aluminum content of around 2% -5%. However, there are many employees, harsh environment, serious pollution, impact on corporate image, and violation of national policies.
Our solution is assembly line operation, crushing screening ball milling screening furnace return. The entire system is closed and equipped with a dust hood. The daily processing capacity is about 330 tons, and it can also be connected with hot ash treatment to improve efficiency.
The processed aluminum particles can be directly used for smelting. Aluminum ash can be used as a raw material for the production of aluminum chloride series water purification agents, enabling the full utilization of waste aluminum through recycling. Alternatively, treated aluminum ash can be used as a joint material instead of ice refined stone as a raw material for aluminum electrolysis.
