Brief introduction of the application of ball mill pre-crushing technology in ball mill


Ball mill pre-grinding technology is an efficient method designed to reduce the particle size of the material before it enters the ball mill, aiming to achieve energy savings and increased production. This technique involves using equipment with higher energy efficiency than the ball mill itself, such as a primary crusher or a high-efficiency grinding system, to ensure that the material entering the mill is reduced to 5mm or smaller. By doing so, the ball mill can operate more efficiently, increasing its output by over 30% while reducing power consumption by 15% to 20%. Additionally, the final product's particle distribution becomes more uniform and suitable for further processing.

So, how can this pre-grinding technology be effectively implemented? According to experts in gold mine ball mill systems, here are some key steps:

1. Use a vibrating screen or rotary screen to classify the crushed material and establish a closed-circuit process. Qualified material is sent directly to the grinding system, while oversized particles are re-crushed for better consistency.

2. After the feed size is reduced, the average ball diameter in the first grinding chamber should also be adjusted downward. This may involve shortening the length of the first chamber and adjusting the position of the diaphragm plates to optimize grinding performance.

3. Increase the air velocity inside the ball mill to improve ventilation. Better airflow helps in removing fine particles more effectively, which enhances overall grinding efficiency.

4. Ensure that auxiliary equipment in the closed-circuit system has sufficient capacity to handle the material flow. This helps lower the system’s circulating load and improves the efficiency of the classification process.

Floor Profiles

PU Floor Profiles are widely used to decorate at the foot base of the wall.

Without PU Floor Profiles, the transition from floor to wall looks unfinished and bare and allows walls to be easily damaged. Skirting boards are more than just decoration. It protects the wall, hides cracks and sometimes also covers expansion areas for parquet floors. You can choose the skirting board that matches the architecture of the room with your own style and size of the room. You can paint it(Floor Skirting,Skirting Boards,Aluminum Floor Profiles,Floor Trim Profiles,Baseboard Moulding,wall baseboard) to achieve the perfect color with other decorations.
