Leading a New Era in Lead Paste Preparation: Unveiling the Secrets of High-Performance Lead-Acid Batteries and Paste Machines
At the heart of lead-acid battery manufacturing, the quality of lead paste directly determines the battery's initial capacity, deep cycle life, and ultimate performance. CO-NELE, deeply engaged in the field of battery production equipment, has dedicated itself to developing a series of high-end paste machines, dedicated to providing you with a comprehensive solution for uniform, stable, and efficient lead paste preparation, laying a solid foundation for manufacturing superior-quality batteries.

What is a paste machine? Why is it so critical in battery manufacturing?

A paste machine is a key front-end equipment in lead-acid battery production. Its primary task is to mix lead powder, sulfuric acid, pure water, and various additives in precise proportions. Through a series of complex physical and chemical reactions, it creates a paste-like substance—lead paste—with a specific density, viscosity, and thixotropy.

Lead paste quality is crucial:

Consistency: This affects the uniformity of the battery pack voltage.

Porosity: This determines the battery's capacity and high-current discharge performance.

Adhesion: This is crucial for the smooth coating process and plate strength. A quality paste mixing machine is the first guarantee for producing high-quality lead-acid batteries.

Core Technical Advantages of Our Paste Mixers
1. Excellent Mixing Uniformity
A unique dual-shaft or multi-blade mixing system design generates intense shear, convection, and diffusion. This ensures that lead powder, acid, and additives are uniformly mixed at the molecular level within a short period of time, completely eliminating dry powder agglomeration and uneven acid distribution, ensuring highly consistent physical and chemical properties for each batch of lead paste.

2. Intelligent Temperature Control System
The lead paste mixing process is an exothermic reaction, making temperature control crucial. Our equipment is equipped with precise cooling jackets/coils and temperature sensors. The PLC automatically adjusts the cooling water flow to strictly control the paste mixing process temperature within the required range (e.g., ≤65°C), effectively preventing lead paste burns and ensuring optimal oxidation and crystal structure.

3. Fully Automated PLC Control
Integrated with an advanced PLC and touchscreen human-machine interface, multiple pre-set optimized process recipes are available. With a single click, the system automatically completes the entire process of feeding, dry mixing, acid addition, wet mixing, cooling, and paste dispensing. Key parameters such as temperature, speed, current, and time are displayed in real time, and production data can be recorded and traced, significantly reducing human error and improving product repeatability.

4. Robust, Durable, and Energy-Efficient

Sturdy Construction: The pot and paddles are constructed of high-strength stainless steel or special alloy steel, offering wear and corrosion resistance and a long service life.

Efficient Drive: Utilizing a renowned brand reduction motor and transmission, the system delivers powerful power, smooth operation, and low energy consumption.

Sealing Design: Excellent sealing prevents dust escape and impurities from entering, ensuring a clean and safe working environment.

5. Flexible Customization

We offer a variety of specifications and models (e.g., 50 kg/batch to 1000 kg/batch) and can customize designs and packages to meet your specific process requirements (e.g., automotive batteries, energy storage batteries, traction batteries, etc.). These systems include automatic metering systems and lead paste delivery systems, allowing for easy integration into modern automated production lines.
