PP Daily Necessities Propylene Glycol Cleaning and Recycling Line

Application:

The PP household waste polypropylene crushing washing recycling line is specifically designed for processing waste household items primarily made of PP, such as old trash cans, basins, stools, shelves, storage boxes, water ladles, children's toys, etc.The PP household waste washing recycling line is an automated system integrating hammer crushing, second crushing, metal sorting, washing, drying and air label separating and rubber/silicone separating, color separating. It can not only handle visible dust and dirt, but also effectively deal with tricky problems such as labels, glue, and small amounts of oil stains, ultimately producing high-quality PP recycled plastic sheets/granules.Hot-washed PP recycled material can easily reach or even exceed the "Grade 1" standard. Its appearance and processing performance are close to virgin material, making it suitable for injection molding of high-end daily necessities, appliance parts, and automotive parts. Its selling price is far higher than "Grade 2" or "Grade 3" material that has only undergone cold washing.

Process:

Manual sorting → Hammer crushing → Metal separator → Friction washing → Sink float washing → Second crushing → Friction washing → Hot washing → Friction washing-Sink float washing--Drying → Air separating → Silicone/rubber separating-Color separating

Features:

1.Interlocked control between each mechanical unit ensures excellent safety and stability, and a high degree of automation across the entire line.

2.Pre-treatment using a powerful hammer crusher, with its robust structure and powerful impact force, can easily process large, irregularly shaped daily into big size waste plastics without prior manual cutting, saving significant manpower. This creates favorable conditions for subsequent crushing and washing.

3.The crusher adopts a large rotary diameter and highly wear-resistant materials, increasing production capacity by 10-15% under comparable operating conditions, addressing capacity bottlenecks across the entire production line and improving crushing efficiency.

4.The vertical friction washer adopts a split design of bearings and seals, which solves easy bearing damage and easy blockage of the discharge port.

5.Hot washing is a core process for recycling PP polypropylene from daily necessities. It solves the stubborn problems that cold water washing and mechanical friction cannot address—adhesives and oil stains. It successfully transforms "low-value, difficult-to-handle" daily necessities waste into "high-purity, high-value" high-quality industrial recycled raw materials, which is key to achieving high-quality recycling.

6.The sink float separation tank features a sloped feed design, improving sink-float separation and washing performance. While the market typically requires two sink float separation tanks, only one tank is needed to separate submersible silicone rubber stoppers and clean the material, achieving the desired effect while reducing energy consumption and the cost of additional machine cost.

7.The Zigzag negative four-channel air separator accurately calculates wind force, air volume, and cross-sectional area to break up and separate the material four times, achieving the desired separation between bottle mouths and bottle bodies with a single machine.

8.With its high-precision and high-efficiency intelligent physical sorting method, it solves the problem of silicone rubber lint and sponge that cannot be solved by density sorting and manual sorting, thus fundamentally ensuring the purity and high quality of the final recycled PP material.
