Belt conveyor plays an essential role in paper waste collecting and handling. It collects and conveys the scrap from the printing machine and die-cutting machine directly to the baling room for further processing. If the path for scrap clearance is long or contains many curves, trim blower could be connected to convey the scrap to baling room through pipeline. Our waste paper belt conveyor is featured by compact structure, less floor space, high energy efficiency and low noise level, offering stable and reliable operation with the ability to integrate into an automatic scrap handling system.

This belt conveyor is mainly divided into three parts, i.e. drive system at front part, support structure at middle part and turning station at the tail part, as well as conveyor belt. In addition, the belt conveyor is equipped with tensioning mechanism and anti-deflection device to ensure a smooth and reliable operation.

The belt conveyor is installed next to the printing machine or die-cutting machine and transport paper wastes to a desired area where two types of waste handling equipment can be linked:

• Connect to trim blower: transport paper waste from belt conveyor to enter the trim blower;
• Connect to baler: transport paper waste from belt conveyor to enter baler;

Functions of trim blower include cutting waste paper into scrap, and providing transport power to convey scrap to the baling room through pipeline for further processing. It is usually equipped with a muffler and an air separator, so as to reduce noise and dust pollutions.
Features: high energy consumption, high noise and dust pollutions. (so that its usage should be minimized!)

With the shredder, corrugated cardboard whether flat or tubed can get crushed and shredded into scarp for further processes of the automatic baling press.

• Blades/teeth on the cutting shaft are made of special alloy steel with special technical processes, featuring high strength and good wear resistance;
• Low rotational speed of the cutting shaft, low energy consumption and noise pollution;
• Promotes quantity and total value of the recycled waste paper;
• Highly-automatic, labor-saving;
• Able for crushing and cutting both flat cardboard and cardboard tube.

The baling press is used to perform baling and recycling on waste paper, cardboards, etc. in a fully-automatic manner. This baling machine mainly consists of bale chamber, main hydraulic cylinder, energy saving hydraulic system, hopper, hydraulic cylinder for compressing bale, MITSUBISHI PLC control system, automatic tying mechanism, etc. Newly designed oil circuit allows for high working efficiency with low consumption. Automatic tying system wraps tie steel wires around the bale after the bale is completely compacted, which prevents it from becoming loose. Featuring high baling speed, it's a type of modern automatic waste recycling equipment.

To separate air and waste paper dust from their high-pressure mixture, two types of air separators can be employed: rotary material separator, and cyclone separator. Inlet of the air separator is usually attached to trim blower’s outlet. Normally, exhausted air from the rotary material separator still contains large quantity of paper dust, and is therefore required to be filtered by pulse jet baghouse dust collector before discharge, and filtered air particulate matter can reach PM2.0 level. Exhausted air from cyclone separator contains little paper dust than that of separator with pulse jet filter, so if the emission standard isn’t too strict, the air from the cyclone separator could be discharged directly.

To remove paper dust from the internal filter media surface with bursts of compressed air, so that outlet air from inertial separator can get cleaned. Main box of the collector is divided vertically into three sections: lower section, middle section, upper section, and a dust hopper is attached at the bottom of the main box. During the cleansing process, dirty air horizontally enters the hopper, where heavy coarse dust falls down directly into. Lighter dust then goes up with the air through the lower and middle section, dust gets drawn against the outer surface of the filter bags, retained and stored, while the cleaned air pass the upper section and get discharged. The pulse jet baghouse dust collector can equip PLC for automated operation of valves to control air outlet, pulse air input and dust discharge automatically.
