Waste Pulper Rope Shredder in Pulper Rope Recycling
During paper production, pulper ropes (a.k.a. pulper braids, ragger wire) are a waste product. Half of the composition is metal or plastic wires because they are used to keep the waste paper in shape and in size. Whilst in the pulper, these contain a variety of contaminations such as plastics, metals, paper fibers, etc.

How to recycle pulper ropes becomes a problem. The pulper ropes have to be disposed of as efficiently as possible. The first step is to downsize the pulper braids(Pulper Rope Shredding). The following is a video of a Pulp Rope shredder machine that downsizes pulper braids, ropes, paper rejects, ragger wire from paper production.

How Pulper Rope Recycling Works
The stream materials are fed into an industrial shredder by crane or forklift. Manually placing the pulper ropes on conveyors also works.

The rest of the work is executed by our Pulp Rope shredder machine, which is fully automated. From detecting the workload to reverse rotate to prevent jamming, the shredding machine keeps the highest efficiency of your size reduction process.

Pulper Rope Shredder Design
Pulp braids(rejects) consist of different waste, and most of them is challenging to shred. It is similar to shredding twine ropes and hemp ropes.

Pulp ropes are rigid and solid often including metals. A one shaft shredder is a good option to handle such a task. A long rotor consistently breaks down pulp ropes into pieces. The special design of the rotor and the clearance between the shredder rotor and counter blade prevent jamming. Within seconds, a chunk of ropes is ready to relocate.

After single shaft shredder or pulper rope shredder, the hemp ropes and dynamic ropes got various applications. Comparing ropes made of plant fabrics, nylon ropes don’t break down easily. Recycling keeps them out of landfills and better, turn them into the carpet fiber, fleece, telephones, skateboards and dog toys to name a few.

A total of 30-35 % of the pulper ropes coming from the paper production process consists of steel wires. The rest of the material when dried is a great source of RDF after shredding and metal separation.

Pulper Rope Shredder Specific characteristics and challenges
When waste paper is recycled, reject pulper ropes are created. Whilst in the pulper, these absorb a mixture of very different contaminations such as plastics, metals, paper fibres, etc. Subsequent to this, the pulper ropes have to be disposed of as efficiently as possible.

The most effective form of reject disposal is to process them as substitute fuels.
Placing the pulper ropes directly into the hopper using handling equipment has proven particularly efficient.
Subsequently, the cutting unit in our shredder shreds the materials in the pulper ropes down to a defined fraction size.
It is then transported away directly with the aid of a conveyor belt.
An overbelt magnet (also known as a magnet separator) simultaneously sorts all metal parts from the material stream.
The fuel thus obtained has a high calorific value and is ideal for thermal utilisation in cement or power plants. In addition, it contains so little contaminated metal that it can be reintroduced into the raw material cycle.
