Allwin’s Wet Grinding Solution – Low Maintenance and Better LFP Batteries

Lithium Iron Phosphate(LiFePO4 or LFP) is a cathode material used in a specific type of Lithium battery. Batteries made with LFP are known for longer battery life, safety, and high energy density. Consequently, Lithium Iron Phosphate batteries are dominating the battery industry, especially in the case of EVs. LFP manufacturers are seeking to participate in this growth to gain a global reach.

Modern wet grinding technology and equipment are transforming the battery industry with intelligent solutions and higher operational efficiency. Here are some precise points to understand the significant impact of wet grinding and bead mills in manufacturing Lithium Iron Phosphate batteries:

• Optimized performance to reduce maintenance frequency and cost
• Produce homogenized LFP slurry for better-performing products
• Prevent agglomeration to ensure consistency
• Boost battery production capacity with precisely manufactured Horizontal bead mills
• Enhanced electrochemical performance with uniform particle size

Challenges Faced with Traditional Bead Mills

Manufacturing LFP batteries on an industrial scale demands consistent operation, low maintenance, and high precision. Traditional bead mills fall short in several critical areas:

• Clogged screens interrupt production
  • Traditional mills frequently clog, especially when using finer 0.3mm media. This causes repeated shutdowns and cleaning cycles, severely disrupting production schedules.
• Imprecise Screen and Mechanical Seals
  • Mechanical seal issues and imprecise screen design led to bead leakage. Consequently, valuable time and resources were wasted due to increased downtime.
• High Energy Consumption, Lower Output
  • Insufficient technology and a labor-intensive approach in traditional bead mills resulted in low output and an increased energy consumption.
• Frequent Maintenance, Increased production cost
  • Traditional mills frequently broke down and required cleaning every two weeks, resulting in unnecessary expense.

Allwin HzPlus: A Modern Solution for Nano-Scale Grinding

Allwin’s Hz Plus nano bead mill series is designed to overcome the key pain points in LFP battery manufacturing – clogging, leakage, energy loss, and unstable production performance with nano grinding. Here’s how our wet grinding equipment enhances performance across the battery industry:

1. Prevent screen clogging with Dynamic Separation System

HZ Plus Super-Fine Nano Bead Mill’s disc-and-rod composite structure enables smooth flow – even with 0.3mm zirconia beads – delivering up to 180 days of continuous operation without screen cleaning.

2. Precisely Designed Wet Bead Mills to Prevent Bead Leakage

Precisely engineered screen rings eliminate bead leakage in wet bead mills, reducing

downtime and removing the need for a secondary separation device.

3. Enhance Efficiency with Nano Wet Grinding

Special elongated chambers in our nano wet grinding equipment offer you better control over particle size, leading to a nanoscale particle reduction.

4. Mechanical Seal with Patented Technology

Allwin’s HzPlus series is equipped with two patented seals and offers reliable operation for approximately 1,600 kinds of solvents.

5. Wet Grinding with Minimal Heat Generation

Our wet grinding equipment offers optimized energy conversion, hence generating minimal heat. Consequently, it prevents damage to the heat-sensitive ingredients.

Let us give you a clear and price comparison between Allwin’s modern grinding solutions and traditional bead mills.

A Proven 12x Improvement in Productivity and Work Stability

At Allwin, we back our claims with proven improvements and a well-documented increase in productivity and efficiency. One of our customers was using an alcohol-based wet grinding process with a traditional pin-type bead mill to manufacture lithium iron phosphate batteries. To achieve uniform dispersion and a finer particle size, they used 0.6 mm zirconia beads. However, the inaccurate grinding system led to blockage and clogging, for which they had to clean the screen ring every 15 days. Consequently, it negatively affected their production schedule and increased their maintenance cost.

However, they were able to turn their situation around with our HZPLUS bead mill. The precise manufacturing equipment enabled them to use even finer grinding media, 0.3mm. It provided them with better control over the particle size in their Lithium Iron Phosphate slurry. Additionally, they were able to cut down their maintenance costs. Because of finer grinding media and precise machinery, their maintenance was reduced to once every 180 days. Thus, they were able to manufacture continuously, fulfilling the promised schedules.
