Waste paper is produced in our daily life, they are shredded documents, cardboards, copy papers, paper cartons, discarded newspapers and magazines at office, classroom, store, street and home.They are not totally the waste and have a very high value. The waste paper has many usages, like packing some goods, being processed into the recycled paper, being processed into fuels, etc. The recycling newspaper saves about 1 ton of wood while recycling print or copy paper saves around 2 tons of wood.
The paper pellets made from paper waste meet the quality requirements of the energy system. Paper pellets has high density and its amount of Btu is similar to coal. Actually, the production cost of paper pellets are relatively low. The biggest cost of paper pellets is the transportation cost. Paper pellets contain less sulfur and produce less carbon monoxide than coal, making them more attractive. Compared to wood, paper has lower levels of formaldehyde.
This alternative fuel reduces demand for landfill space, reduces fuel costs, and minimizes hazardous emissions.
In fact, the process for pelletizing paper is much the same as that for pelletizing wood and other biomass materials. The fundamental difference between wood and waste paper pelletizing is the fact that wood pellets generally are made with a more homogenous feedstock selection, while paper pellets are dealing with a lot of material that has extreme swings in density. However, waste paper pellets occur little amount of degradation, and usually can hold up pretty well.
With a comparable price and the ability to be handled just like coal, as well as resistance to weather-related degradation, paper pellet biomass fuel is becoming the choice of more and more people.That kind of energy can not only be a substitute of traditional fuels, but also protect the environment, which is a kind of perfect energy. Waste paper pellets belong to that energy.
So, it is a good idea to make waste paper into pellets by biomass pellet mill for your own use or for business purpose.
How to make paper pellets from waster paper? What’s the price of paper pellet machine?
1.Collecting and sorting
Waste papers are abundant in schools, printing companies, market, and office buildings. Paper mill residues are another important source. These materials have different sizes and features, you need to sort them in groups for future processing.
2.Waste Paper Grinding
There are different size paper you colletct ,a hammer mill can help you to crush large size of waste papers into proper powder size.
Shredding paper to the required size will create a lot of dust. Wear a mask to protect your lungs. Use the hammer mill machine and pellet machine in a well-ventilated area to avoid combustion of the dust.
3.Waste Paper Drying
If the moisture content is over-high,the pellets are too wet to burn well, you need to lower it by a dryer machine.If the papers are too dry, it would cause static charge and make the pellets light and fluffy, you can add certain amount of water when processing.
The moisture content of paper materials should be 12%-15%.
4.Waste Paper Pelletizing
This is the key step of making paper pellets. Feed materials of proper size and moisture content into the high quality ring die paper pellet mill . They will get compressed and molded in the compression chamber and come out in the shape of cylinders.
5.Waste Paper Pellet Cooling
The newly produced paper pellets has high temperature of 90 ℃. So you need a pellet cooler to lower the pellets to room temperature. Cooling can improve the stability and hardness of paper pellets. If it’s small capacity, you can put the paper pellets in open air for natural withering.
Use a sieve to remove the residual powders in the paper pellets. These powders can be re-pelletized together with the left materials.
7.Finished Pellet packing
Pellet packing machine is essential for commercial paper pellet production. It can weigh and package the pellet products in bags. Package can protect the paper pellets from erosion of moisture and wind. Pellets can be stored in the closed silos.
