This PP battery box recycling machine is used to clean dirty rigid plastics such as pp plastic waste, HDPE/PP bottles, lumps and or other rigid plastics. This complete pp battery box recycling solution includes a heavy-duty shredder with overhead magnet, plastic crusher, sink-float separation tank, centrifugal dryer, thermal dryer, zig zag separator and a dual-bag filling station. The resulting high-quality plastic flakes produced can be used in manufacturing plastic products again.

The capacity of this recycling system ranges from 500 kg/hr to 2000 kg/hr.

Lead-acid battery box recycling cleaning does not need hot washing, PP battery box material is very heavy, sinking in the bottom of the water, lead-acid battery box has calcium carbonate, so pp battery shell cleaning line, have to use SS304 stainless steel washing because the material has sulfuric acid, corrosive very large.

Why do we need to recycle PP lead-acid batteries?

Environmental & Regulatory Pressure — Lead-acid batteries are one of the most widely recycled consumer products globally, yet improper disposal of spent batteries poses severe environmental risks. Sulfuric acid leakage and lead contamination can damage soil and water systems for decades. With tightening environmental regulations worldwide, compliant battery recycling is no longer optional—it’s a legal and social responsibility.
High-Value Material Recovery — A typical lead-acid battery contains 60–80% lead, 10–15% sulfuric acid, and 15–20% polypropylene (PP) plastic. Our recycling line effectively separates these three components: recovered lead is smelted for reuse, acid is neutralized and treated, and PP battery shells are crushed, washed, and pelletized into high-quality plastic flakes ready for remanufacturing.
Corrosion-Resistant Design — PP battery boxes contain calcium carbonate and residual sulfuric acid, making them highly corrosive. Unlike standard plastic recycling lines, our system uses SS304 stainless steel throughout the washing section to withstand chemical attack, ensuring equipment longevity and consistent output quality. No hot washing is required—cold-water friction cleaning safely removes acid residue.
Closed-Loop, Zero-Discharge Process — Our brine float-sink separation system recycles separation fluid internally through pipeline circulation. Brine is automatically replenished as needed, with zero brine discharge into the environment. This design eliminates wastewater treatment costs while meeting the strictest environmental compliance standards.
Scalable Output for Growing Demand — System capacity ranges from 500 kg/hr to 2,000 kg/hr, accommodating small recycling plants to large industrial operations. As electric vehicle and energy storage markets expand, the volume of end-of-life batteries is surging—positioning battery box recycling as a high-growth, high-margin business opportunity.

PP Battery box recycling crushing and washing process:

Waste PP battery box recycling crushing, washing, sorting, production process instructions.

(1) The PP battery box is sent into the slow storage bin by forklift, and after the storage bin, the material can be sent into the conveyor belt for quantitative feeding at a uniform speed.

(2) Irregular materials are removed from iron through the belt conveyor.

(3) After large crusher to crush the PP battery box into an ideal state.

(4) Into the loading washing machine for high-speed friction, in the process of material and material friction with each other in the external non-stop water rinsing (this link can remove the residual dilute acid on the surface of the material)

(5) and then by high-speed vertical friction dewatering machine will be completely removed from the surface residual liquid so that the material can be smoothly carried out in the next step of the brine sinking process.

(6) The sinking and the floating separation water tank is separated by the specific gravity of brine, and all the required plastics are floated.

(7) The brine is separated from the material by loading dewatering, and the separated brine is directly fed into the flotation separation tank through the pipeline for internal recycling, and all the brine is not discharged in this process, so there is no need to go through the rolling screen and filter tank.

(8) After desalination, the material enters the clear water rinsing and sinking water ABS through the bottom spiral to the dewatering machine for dewatering treatment.

(9) The floating water PP is fished out by the automatic spiral reclaimer. It is noted here that if the treatment is floating water PP then the floating water PP will automatically enter the dewatering machine through the spiral reclaimer. Thus, automatic conversion is achieved.

(10) Dewatering process is carried out.

(11) After dewatering, the floating PP or ABS will be dried.

(12) The blower feeding system will send the material to the next process.

(13) After the drying process, the material will enter the wind separator for film separation.

(14) The drying heating sheet ensures that the material moisture is not higher than 1%, and the material is sent to the storage bin through the wind feeding system.

(15) Storage bin for material caching.

(16) In this process, there will be no brine discharge, only the adjusted brine will be replenished into the brine-specific gravity separator from time to time by the brine automatic adjustment equipment.

(17) The PP plastic obtained can be passed through the plastic pelletizer machine and made into new plastic pellets again.
