Nylon salt mill line machine is one of the key equipments in recycling plastics, especially nylons (such as nylon packaging, bags and films). Its task is to crush, wash, dry and prepare waste nylons for granulation.

Let's explain its operation step by step:

🧩 The main components of the nylon salt mill line

grinding machine

Crushes waste nylons into smaller pieces.

It usually has durable steel blades.

It has a high speed and the pieces are crushed to about 1-2 cm.

Washing tub (hot or cold water pool), the crushed parts enter the water tank.

Contaminations such as dirt, glue, paint or printing materials are removed.

Sometimes detergents or hot water are used for better cleaning.

Centrifuge device (primary dryer)

Dehydrates washed nylon to a great extent by rapid spinning.

Air dryer (Dryer)

Through the flow of hot air and high pressure, the nylons are completely dried to be ready for the next step.

Conveyors (screw or conveyors)

They have the task of moving crushed material between sections, often made of stainless steel.

⚙️ How the line works

Loading waste nylon in the opening of the mill

shredding the nylon and transferring it to the washing tub

Complete washing to remove pollutants

Exit from the bath, initial centrifugation and drying

Collecting and sending dry nylon to extruder or granulation machine

✅ Benefits

Increasing the quality of production granules

Decreasing the amount of pollution and unpleasant smell of recycled materials

Reduced extruder depreciation due to cleaner materials

Possibility of reusing washing water (in advanced lines)

⚠️ Important points in operation

Precise adjustment of grinding speed to prevent heating of nylon

Regular replacement of blades to maintain shredding efficiency

Proper water filtration to prevent bathtub clogging

Using a drying system with optimal energy consumption
