Case Study- SANY

The pigging system (product recovery system) implemented by Hyperfore has led to a significant increase in profitability for China SANY in the production of lithium battery slurry. This improvement is primarily due to the system’s ability to enhance yield, reduce waste, increase efficiency, and promote environmental protection.


Hyperfore has installed two sets of automatic pigging systems specifically designed for the lithium battery industry in two coating machines in SANY’s workshop. These two coating machines are identical in appearance and located on opposite sides of the workshop. The mixed solution of powder and water, known as slurry, is stored in a large mixing tank. At the outlet of the mixing tank, there is a rotor pump that pumps the slurry to the pipelines and then to the two small storage tanks at the head and tail ends of the coating machines. Our automatic pigging system is installed between the head and tail ends of the machine, collecting residual slurry from the pipelines and returning it to the storage tank at the head end. This allows the slurry in these two storage tanks to be used as aluminum-based coating for the coating machine. After installation, our pigging system has been working well, reducing waste of lithium battery slurry, improving production efficiency, and achieving customer goals.

Project Introduction

Sany Group is a leading manufacturer of lithium battery slurry, and they have a branch that specializes in this product. The slurry needs to be transferred from the tail end to the head end of the coating machine, which are two different positions in their plant. However, after the transfer, a lot of slurry remains in the pipeline, and it cannot be delivered to the storage tank due to its sticky nature. As a result, it has to be washed away as waste. To address this issue, Sany Group is looking for a way to recover the left slurry. Our customer, who has never used a pigging system before, is worried about the pigging system price. Meanwhile ,they don’t know how to choose pigging system. They have two pipelines that need to be recovered, the slurry viscosity of around 8000CPS, and the pipeline length of 100m, and a diameter of DN65. We assure them that our pigging system can handle this viscosity without any issues. They also express concerns about the reduced cross-sectional area of the pig due to its placement in the launching station. However, we explain that the pig only occupies a quarter of the cross-sectional area, so this should not be an issue. Since the lithium ion battery slurry is conveyed along the main pipeline, the destination tank is on the bypass line. Based on this information, we recommend our automatic pig stopper and piggable ball valve to our customer. One of the major functions of the pig stopper is to block the pig from moving while allowing the slurry to pass through. By combining the piggable ball valve, the product can be delivered to the designated storage tank. This system provides an efficient and cost-effective solution for recovering lithium battery slurry without wasting valuable product.

The project result

The pigging system has been successfully put into use and is running very well. The plant now runs the pigging system twice a day, which means that the frequency of lithium ion battery slurry recovery is about 60 times a month. By using our pigging systems, they are able to save 1.6 tons of product every day, which amounts to approximately 8000 yuan per day and 240,000 yuan per month. This translates to a significant return on investment for our customer in just a few months.Whenever the plant encounters operating problems, they turn to us for remote technical support. Our patient and professional guidance always makes them feel very pleased and satisfied. The customer also believes that our pigging system and the turnkey project have updated their production process and raised efficiency significantly.One of the key advantages of our pigging system is its ability to recover valuable product that would otherwise be wasted. By recovering around 8000 yuan per day, the customer is able to generate significant cost savings over time. In addition, the use of our pigging system has improved the efficiency of their production process, allowing them to achieve higher output levels with less waste and lower costs. Our team takes pride in providing excellent customer service and support. We understand that any operational issues can have a significant impact on a business, which is why we are committed to providing timely and effective solutions to ensure that our customers can continue to operate at maximum efficiency. We are confident that our pigging system and turnkey project will continue to provide value to Sany Group for many years to come.
