Palm Papers sets new standards for paper sorting in England.
The new fully automated paper sorting plant, built by Entsorgungstechnik BAVARIA, will be inaugurated in September 2019...
After an intensive period of preparation, Palm Paper is building a new paper sorting plant for the production of deinking recovered paper in King's Lynn, northeast of London, directly next to the existing paper mill. With this investment decision, Palm Paper is increasing its commitment in the UK.
The sorting plant is designed to recycle an annual volume of appox. 200.00 t waste paper that is collected close to households.
Palm decided to commission Entsorgungstechnik BAVARIA GmbH from Unterschleißheim near Munich for he planning and the construction of the sorting plant. The Munich-based company is considered to be the specialist for plant construction in this field for many years.
The primary objective of the installation is besides a consistently high final quality, guaranteeing optimum efficiency as well as a fully automated sorting process.
In order to define the optimum plant configuration for an efficient sorting plant, targeted at the input material, the Palm paper mill, headquartered in Aalen, Germany, in cooperation with Entsorgungstechnik BAVARIA GmbH, carried out tests with English waste paper on several paper sorting plants in advance.
The main issues were the composition of the input material, detection of impurities and automatic sorting out of foreign matters in order to generate from the input the highest possible proportion of white or deinkable paper in high purity.
It was a particular challenge to achieve a comparably good quality despite worse input material than it is usual in Germany.
The plant is equipped with the latest sorting technology. As in many other plants, there is a BAVARIA dosing bunker at the beginning of the recycling line. This bunker ensures an even and well separated material output for the further sorting operation. The more evenly the material flow is distributed on the conveyor belts, the better the sorting result on the subsequent sorting units.
In the field of coarse and fine screening, Palm relies on the BHS disc roll screens that have been tried and tested in paper sorting for years. Due to the sorting plants installed by Entsorgungstechnik BAVARIA throughout Europe for many years, the perfect screening configuration consisting of coarse and fine screens could be determined. Even at high throughput rates, these machines are very compact due to the screening technology used and guarantee excellent screening results.
The latest generation of near infrared machines of the Redwave series „2i“ ensures high quality. Using the combined visual and near infrared detection system, grey, brown and printed cardboard and non-paper materials can be detected and removed from the deinking stream by using compressed air.
Thanks to the new sensor technology, the new generation of these machines is able to offer more accurate and faster material identification.
The highlight of the sorting system is that it goes without the usual manual sorting.
In order to achieve these standards, BAVARIA has developed the MAX POS process optimization system together with the "Papiertechnischen Stiftung PTS“ (Paper Technology Foundation) and in cooperation with the near-infrared machine manufacturer Redwave.
This means that the quality is monitored and optimized during the entire sorting process by real-time monitoring.
Online monitoring collects real-time information about material data, sorting parameters and the current quality status. The information about changes in the material composition and the material flow on the conveyor itself provides an early warning.
Reliable data on material, plant, processes and influencing factors as well as the recording of statistics and trends support the operator in the operational process and offer greater reliability in the long term.
This leads to a sustainable increase in efficiency and highest quality of process outcome.
The plant is equipped with an ultra-modern dedusting system to prevent possible dust accumulation. Extraction points are provided at all hot spots. The transport air of the dedusting plant is cleaned in a clean air filter and returned to the sorting-halls with a cleanliness of 99. 8%. This dust reduction measure serves not only to increase the quality of work but also to prevent fire risks.
Online monitoring of the aggregate states, e. g. bearing temperature control, provides additional operational security.
In addition to the positive effect of preventive maintenance, this increases fire protection precautions.
In view of declining demand from China and efforts to improve the quality of recovered paper as a raw material, this plant offers Palm Paper special opportunities for sustainable recycling.
