H R Plastic Industries

A single-stage HDPE blue drum recycling granules plant is designed to process used HDPE drums into reusable granules using a streamlined process that eliminates the need for multiple extruders. This type of plant is cost-effective, requires less energy, and is suitable for medium-scale operations.

• Used HDPE blue drums are collected from industries, warehouses, and scrap dealers.

• Sorting is done to separate pure HDPE drums from contaminated or mixed plastics.

• Non-HDPE materials such as metal rings, caps, and labels are manually removed.

• The HDPE drums are fed into a shredder to break them into smaller flakes.

• The size of flakes (approx. 10–50mm) is adjusted depending on processing needs.

• The flakes go through a friction washer to remove dirt, oils, and labels.

• A hot water wash (optional) with caustic soda is used for chemical drum cleaning.

• The washed flakes are dried using a centrifugal dryer or a hot air dryer.

• The dried flakes are directly fed into a single-screw extruder (no need for agglomeration).

• The material is melted at 180-220°C, mixed, and pushed through a filter screen to remove impurities.

• The molten HDPE passes through a die head and is cooled using a water bath.

• The cooled strands are cut into granules using a pelletizer.

• The granules are screened for uniformity in size.

• The finished granules are packed in 50 kg or 1-ton bags for sale.
