Processing various types of waste lithium batteries, ternary, iron lithium, cylindrical, soft packaging, etc

The degree of automation is fully automatic (PLC control), reducing manual intervention and improving safety

Detailed explanation of process flow

one ️⃣  Preprocessing stage

Safe discharge: Release residual energy from the battery by soaking it in salt water or using a dedicated discharge machine to prevent short circuits and fires

Feeding and conveying: The chain plate conveyor sends the battery into the primary shredder

two ️⃣  Crushing stage

First level shredding: The dual axis crusher shreds the battery into 2-3cm strips

Secondary crushing: Hammer crusher further crushes to 5-8mm particles

Third level crushing: The turbine mill refines the material to 3-5mm, achieving separation of metal and powder

three ️⃣  Sorting stage (core stage)

Magnetic Separation: Separating Ferromagnetic Substances

Gravity sorting: using negative pressure and a "Z" type separator to separate the shell (recovery rate ≥ 98%)

Airflow sorting: Separate copper (heavy), aluminum (medium), and diaphragm (light) based on density differences

Screening: Drum screen separates positive and negative electrode powders according to particle size (mesh size 100-120)

four ️⃣  Environmental Protection Treatment System

Third level dust removal: cyclone dust removal → pulse dust removal → activated carbon adsorption to ensure dust meets standards

Waste gas treatment: spray tower+catalytic combustion, VOCs removal rate>99.5%

Wastewater recycling: achieving "zero wastewater discharge" and meeting environmental protection requirements

Comparison of technical routes

At present, there are three main technical routes for 500kg/h lithium battery recycling machines on the market:

Technical roadmap, principles, advantages, disadvantages, applicable scenarios

The physical crushing method, which involves pure mechanical crushing and sorting, has a low investment (3-8 million yuan) and low energy consumption. It is only suitable for small batteries and has a high risk of handling power batteries. It is also suitable for recycling small batteries such as mobile phones and power banks

Low temperature pyrolysis method with 200-300 ℃ anaerobic environment pyrolysis+sorting has high safety, high processing efficiency, 30% high profit of power batteries, high investment (10-30 million yuan), high energy consumption, power battery recycling, and pursuit of high purity

The combination of wet and dry physical crushing, pyrolysis, and wet purification has the highest recovery rate (≥ 99%), high product purity, complex process, and highest investment. It requires high-end recycling of wastewater treatment and pursues battery grade raw materials

Note: 500kg/h equipment often adopts a combination of physical and pyrolysis processes, balancing efficiency and safety

Investment return analysis

economic performance:

Investment scale: Approximately 5-8 million yuan for 500kg/h standard equipment (physical method); Thermal decomposition type costs about 10-15 million yuan

Operating costs:

Electricity: Approximately 185-361kWh/hour (depending on configuration)

Manual: 3-5 people/shift (can be reduced to 1-2 people in fully automatic mode)

Replacement of vulnerable parts: approximately 50000 to 100000 yuan per year

Recycling income:

Each ton of waste lithium batteries can recycle about 150kg of copper (worth about 120000 yuan/ton)

70kg aluminum (valued at approximately 14000 yuan/ton)

200kg black powder (containing lithium, cobalt, etc., valued at approximately 30000 to 80000 yuan/ton)

The comprehensive recycling value of waste batteries is about 160000 to 220000 yuan/ton

Return cycle: about 18 months for pyrolysis method; Physical methods take approximately 12-15 months (depending on the source of raw materials and market prices)

Environmental benefits:

Reduce heavy metal pollution and protect groundwater resources

Reduce dependence on primary minerals and realize the value of "urban mines"

Reduce CO ₂ emissions and contribute to carbon neutrality goals

Key points and precautions for purchasing

one ️⃣  Clearly handle requirements

Confirm the main types of batteries being processed (ternary, lithium iron, consumer or power batteries)

Assess future business expansion space, considering device compatibility and scalability

two ️⃣  Technical route selection

Handling power batteries: prioritize pyrolysis or wet dry combination for higher safety and recovery rate

Dealing with small batteries: Physical methods offer higher cost-effectiveness

Pursuing high purity: choosing a comprehensive process with wet purification

three ️⃣  Comparison of key indicators

Recovery rate: Black powder ≥ 96%, copper and aluminum ≥ 97% are high-quality standards

Energy consumption: should be less than 200kWh/ton of waste batteries, the lower the better

Environmental indicators: Dust<20mg/m ³, VOCs removal rate>99.5%

Stability: Evaluate the continuous operation time and failure rate of the equipment

four ️⃣  after-sales service

Installation, debugging, and training services

Warranty period (usually 1 year) and maintenance response time

Supply of vulnerable parts and technical upgrade support

Policy support and industry prospects

Policy environment:

The "Industry Standard Conditions for Comprehensive Utilization of Waste Power Batteries in New Energy Vehicles" issued by the Ministry of Industry and Information Technology clearly require recycling enterprises to have professional processing equipment

The environmental protection department stipulates that those engaged in lithium battery recycling must obtain a hazardous waste management license and a record of renewable resource recycling operations

Multiple regions have introduced subsidy policies to support the development of the lithium battery recycling industry

Market prospects:

It is expected that the global lithium battery recycling and processing capacity will exceed 1.8 million tons by 2025, with a market size of 3.5 billion US dollars

The Chinese market accounts for over 55% and has become a global core

500kg/h equipment has become the preferred choice for small and medium-sized recycling enterprises due to its moderate production capacity and investment scale

Reminder: Environmental impact assessment, safety assessment, and hazardous waste permit application must be completed before investment to ensure compliant operation

summary

The 500 kg/h lithium battery recycling machine is currently the ideal choice for small and medium-sized lithium battery recycling enterprises, which can meet the recycling needs of a certain scale while maintaining moderate investment and operating costs. When selecting, the appropriate technical route should be chosen based on the type of material being processed, budget, and long-term planning, with priority given to the equipment's recovery rate, energy consumption, and environmental indicators. With the rapid development of the new energy industry, the lithium battery recycling market has broad prospects, and 500kg/h equipment will become an important equipment for the development of "urban mines".
