Core Features

Tailored to the exclusive processing needs of lithium battery materials

Unlike ordinary crushing equipment, the Lithium Battery Material Pulverizer fully considers the special characteristics of lithium battery materials in its structural design and material selection. In response to the high hardness of positive electrode materials and the easy oxidation characteristics of negative electrode materials, it adopts a fully sealed inert gas protection structure and is matched with customized wear-resistant and anti-corrosion lining plates, effectively avoiding oxidation of materials in contact with air and preventing materials from causing wear to the equipment. Compared with the universal building materials chemical ultrafine crusher, this product pays more attention to "low impurity introduction", and the parts in contact with the material are made of food grade stainless steel or ceramic materials to ensure the purity of the crushed material and meet the strict standards of lithium battery production.

In addition, the Lithium Battery Material Pulverizer inherits the core advantages of high efficiency and energy saving in building materials and chemical ultrafine crushers. It adopts the "impact+grinding" composite crushing principle, combined with high-frequency grading impellers, to accurately crush materials to 500-3000 mesh, with a particle size uniformity error of ≤ 3%. It can significantly improve the specific surface area and electrochemical performance of lithium battery materials, and help upgrade the performance of battery products. The device also has intelligent temperature control function, which can effectively control the temperature rise generated during the crushing process, avoiding high temperature damage to the performance of lithium battery materials.

Operation Steps

✱Material pretreatment: Remove metal impurities and large hard blocks (particle size ≤ 5cm) from the raw materials, control the moisture content ≤ 3%, and prepare inert protective gas in advance for easily oxidizable materials;

✱Equipment debugging: Start the Lithium Battery Material Pulverizer, set parameters such as particle size, speed, and inert gas flow rate through the touch screen, run the machine empty for 5 minutes, and check if the sound, temperature, and sealing performance of the equipment are normal;

✱Feeding operation: Open the inert gas circulation system (if necessary), evenly and continuously feed, avoid excessive feeding causing blockage, and monitor the crushing status in real time through the observation window;

✱Finished product collection: After being crushed and screened by a grading impeller, the material is transported through a closed pipeline to an inert gas protected storage tank for regular sampling and testing of particle size and purity;

✱Shutdown cleaning: Turn off the power and inert gas system, wait for the equipment to completely stop running, and use inert gas to blow away residual materials inside the equipment to avoid oxidation and agglomeration of residual materials.

Precautions for using Lithium Battery Material Pulverizer

1.It is strictly prohibited to introduce hard impurities such as metal and stones to avoid damaging the blade assembly and lining plate, which may affect the purity of the materials;

2.When handling easily oxidizable materials, it is necessary to ensure good equipment sealing and sufficient inert gas to avoid material oxidation and combustion;

3.During equipment operation, operators must wear protective equipment such as dust masks and gloves, and are prohibited from opening equipment access doors;

4.Regularly (every 40 hours of work) check the lubricating oil level, tool wear, and aging degree of seals, and promptly replenish or replace them;

5.The equipment should be installed in a flat, dry, and ventilated workshop, away from sources of fire and flammable and explosive materials, properly grounded, and regularly inspected for circuit safety;

6.Unlike the use of building materials chemical ultrafine crushers, the Lithium Battery Material Pulverizer needs to thoroughly clean the interior of the equipment after processing a material to avoid cross contamination of different materials.

FAQ

Q1: How to avoid oxidation when processing the negative electrode material of Material Pulverizer?

A: The equipment is equipped with a fully sealed chamber and an inert gas circulation system, which can continuously introduce nitrogen or argon gas to replace the air inside the chamber, so that the oxygen content in the chamber is ≤ 1%, and the oxidation of the negative electrode material is avoided from the root; At the same time, the parts of the equipment that come into contact with the material are made of low friction coefficient materials, reducing the temperature rise generated during the crushing process and further ensuring the stability of material performance.

Q2: What is the core difference between this equipment and ordinary building materials chemical ultrafine crushers?

A: The core difference lies in the design of "anti-oxidation" and "low impurity": ordinary building materials and chemical ultrafine crushers focus on wear resistance and multi material adaptation, while Lithium Battery Material Pulverizer adds an inert gas protection system, and the parts in contact with materials are made of high-purity, low shedding materials, strictly controlling the introduction of impurities; At the same time, the temperature control structure has been optimized to avoid the impact of high temperature on the performance of lithium battery materials, which is more in line with the special processing needs of the lithium battery industry.

Q3: Does it support customizing equipment based on the characteristics of my materials?

A: Fully supported. The physical and chemical properties of different lithium battery materials vary greatly (such as hardness, oxidation, moisture content, etc.). We can customize exclusive crushing knife sets, lining plate materials, inert gas system parameters, and equipment production capacity based on the material samples provided by customers. At the same time, we draw on the multi material adaptation experience of building materials chemical ultrafine powder crushers to ensure the adaptability and crushing effect of the equipment.

Q4: Is there any guarantee for the installation and after-sales service of the equipment?

A: The whole machine is guaranteed for 1 year (excluding vulnerable parts), and technical response will be provided within 24 hours after equipment failure.

Q5: Which model is more suitable for small and medium-sized lithium battery material enterprises to choose?

A: It is recommended to choose a medium-sized Material Pulverizer with a production capacity of 100-200kg, a motor power of 37-55kw, low energy consumption, small footprint, and moderate price, which can fully meet the pilot and mass production needs of small and medium-sized enterprises; If the output increases in the later stage, it can be upgraded to a large-scale model without the need to replace the supporting inert gas protection, dust removal, and storage equipment, reducing the cost of secondary investment. At the same time, this model is compatible with various lithium battery material processing, with higher cost-effectiveness.
