Working Process of Battery Recycling Rotary Kiln

The complete system of battery recycling rotary kiln consists of a feeding device, kiln body, discharging device, heating device, control unit, etc. The heating device heats the surrounding environment of the materials in the kiln to gradually increase the temperature. When the temperature measured by the thermocouple reaches the requirement, the temperature will not continue to rise, and the material can be discharged after the reaction time reaches the specified value, and the whole process is safe and efficient.


1.    The feeding system is usually equipped with a screw feeder or vacuum feeder for quantitative conveying.

2.    The heating kiln generally includes a pre-heating zone and a high-temperature heating zone. There are multiple temperature zones in the pre-heating zone and the high-temperature heating zone, where the temperature of each temperature zone can be set separately, and the temperature of each zone of the equipment

 is required by the process.

3.    According to different material characteristics, Hywell machinery's engineers will design whether the rotary kiln body needs an angle according to the material characteristics. Because our company's rotary kiln has a horizontal kiln body and an inclined kiln body.

4.    The heating way of the battery materials rotary kiln have electrical heating or burn gas /oil heater. if the machine heater install electrical heater, the resistance wire is arranged at the bottom of the kiln body to indirectly heat the material.

5.    The cooler is usually a drum cooler, the material passes through the inside of the cylinder, and the outside is sprayed with water to indirectly cool the material to meet the discharge temperature requirements.

Battery Recycling Rotary Kiln Application

The Battery Recycling Rotary Kiln is used for the recycling and calcination of lithium battery materials, positive electrode materials, and negative electrode materials.

Lithium battery recycling rotary kiln can also be called the waste lithium battery calciner, which is suitable for recycling and sintering power lithium batteries, lithium iron phosphate batteries, ternary lithium, and other lithium batteries.

As an experienced rotary kiln manufacturer, Hywell Machinery has outstanding technology for top production. The lithium battery recycling rotary kiln designed and produced is suitable for a wide range of powder calcination and sintering processes. As an electric heating rotary kiln, the lithium battery recovery rotary calciner has precise atmospheric adjustment inside the rotary shell. The inclination angle and rotation speed of the waste battery rotary calciner can be adjusted, the cylinder has good heat transfer and short cycle time, and the production capacity is also higher.


Advantages of Battery Recycling Rotary Kiln

Compared with gas-fired rotary kiln and oil-fired rotary kiln, electric power used by electric rotary kilns is the cleanest energy source. Electric energy can be easily connected to the factory and supplied to the electric heating rotary kiln along with the power supply line.

The advantages in the production process of the electric rotary kiln are also obvious.

•      High thermal efficiency, no smoke, no ash, and slag to take away obvious heat.

•      It is easy to automatically control the conditions, the kiln temperature control accuracy is high, and it is suitable for the narrow pre-firing temperature process.

•      In addition, the electric rotary kiln does not need to build fuel storage and transportation station, which simplifies the work of fuel procurement, transportation, and safety management. During the production process, the corrosion of the kiln body due to SO2 gas and environmental pollution problems can be avoided. Therefore, the electric heating rotary kiln is more economical than the gas fuel rotary kiln and the oil fuel rotary kiln.

Battery Recycling Rotary Kiln for Recycling Precious Metals

600 Degree Recycling Rotary Kiln High-Temperature Pyrolysis Lithium Battery for recycling precious metals. Lithium battery pyrolysis recovery technology is mainly to extract precious metals from decommissioned power lithium batteries for recycling, and Hywell Machinery mainly provides the core pyrolysis rotary kiln process and technology.

The waste lithium battery enters the kiln. After a high temperature of 600 degrees, the easily cracked components in the lithium battery are cracked off, and the remaining precious metals are recycled for reuse.

It is understood that China’s annual decommissioning of lithium batteries can reach about 500,000 tons. The rotary kiln of Hywell Machinery can process 1-2 tons per hour, and the annual max processing capacity is about 15,000 tons. To process the 500,000 tons of waste lithium batteries, dozens of such production lines are needed. The market scale should not be underestimated. In recent years, various national ministries and commissions have also gradually standardized and improved the recycling market for waste lithium batteries from the shallower to the deeper, from weak to strong at the policy level. Seeing this business opportunity, Hywell machinery has been cultivating lithium battery-related industries since 2014 and has basically opened up all technical links from lithium battery production to recycling.

This rotary kiln can achieve "atmosphere calcination", that is, it can control the oxygen content in the kiln. "The gases after high-temperature pyrolysis are mostly flammable and explosive gases, which have the risk of explosion." we can control the oxygen content in the kiln to keep it in a low-oxygen environment and ensure safe production. The performance is greatly improved.” This technology has a very good application prospect in the industry.

Recycling Solution with Rotary Kiln Thermolysis

Rotary Calciners are a highly effective and cost-efficient means for high-temperature processing of various granular products and powders. The unit is specially designed to provide for controlled and uniform process conditions.

Material is fed into a rotating cylinder that is externally heated according to process-related time versus temperature criteria. As the cylinder rotates, the material is gently tumbled as it flows from the feed end of the cylinder to the discharge end. The action promotes uniform exposure of the product to a defined environment. Various processes employ reaction gases in direct contact with the product to propagate a given reaction or cover gases to protect the product.

Proper selection of the calciner cylinder material is critical and is determined by process temperature, process compatibility, and physical size considerations.

Hywell Machinery rotary calciners are provided with automatic temperature, pressure, and electrical controls with furnaces featuring multiple gas, oil, or dual fuel burners, or electrical heating elements arranged in zones. Available in sizes ranging from 50-3000mm diameter with lengths from 5 to over 20m.


Battery Recycling Rotary Kiln Advantages

Compared to conventional tunnel kiln or mesh belt-style equipment.

• Maximum Product Uniformity – the material bed is constantly being turned over, and all of it is exposed uniformly to its required environment.

• Greater Yields – all of the material is processed, and none is overheated or underheated.

• Reduced Process Time Factor – due to uniform exposure and dynamics of the products, process time requirements are drastically reduced.

• Capital Costs – with reduced process time requirements, the equipment is smaller and therefore less costly.

• Operating Costs – the material is continuously conveyed eliminating the ongoing replacement costs of holding containers and automation devices.
