如何通过木锯末颗粒磨机制造优质木锯末颗粒？

加工木屑所需的设备包括锤式磨机破碎机，干燥机，木材造粒机等。其加工技术如下：

1.Sawdust preparation

由于锯末抵达锯末颗粒机厂，应测试水分含量。水分含量在材料的总重量中赋予蒸发水的比例。具有高水分含量的木锯末应与低水分含量锯末分开储存。1吨颗粒的生产需要约7个散装M³锯末，水分含量约为50-55％。锯末的最佳水分含量为10-15％。在进入锯末颗粒机之前，应干燥具有较高水分含量的锯末，而较低的颗粒机可以跳过该程序。

2.Drying

The wet sawdust should be dried before size reduction because the wet sawdust consume more power to be hammered than the dried one does. And also the wet sawdust may risk the screening by clogging or smearing the screen. Drying can be done by the dryers.

3.Screening

The screening of the sawdust is to remove the stones, plastics, metals, or other hard materials that may damage the equipment. The stones and stone like hard materials are removed by a stone trap when the sawdust passes over the screen while the metals are picked up by a magnet.

4.爆发

锤击旨在使锯末均匀化为偶数。在桩和成堆的锯末可能是木块，死结等，需要锤击，使它们可以通过锯末颗粒机的模具孔。

5.造球

When the sawdust goes into the pelletizing chamber of the sawdust pellet machine, the lignin of the sawdust will be heated up to 120-130 ℃ by the heat produced by the running sawdust pellet machine and by which the lignin will be plasticized and binds the particles together to help to mold the pellets. The pellets are molded by being pressed through the pellet ring dies of the sawdust pellet machines and then are cut off by the cutter with the desired length. During the pelletizing, the binder may be needed to improve the pellet strength and durability.You needgood quality ring die wood pellet mill在这个部分。

6.冷却

The moment when the pellets leave the sawdust pellet machines, they are hot and plastic. Then they need to be cooled down to become hard and rigid and to dry up so that the final moisture content after the cooler can be as low as 6% which may be increased up to 8 to 10 % by absorbing moisture from the surround air.

7.包装

Before packaging, the pellets will be screened again for recycling the fines. And then the pellets will be packaged. For domestic users, the pellets are preferred to be packed into bags with the sizes of 12, 15, or 20kg. while for exporting, the pellets are usually shipped in one tone bags or in bulk which are usually wrapped in plastic to keep the moisture out. Compare with the large bulks or bags, the small bags are better for the pellets because the pellet are subject to less abrasion during delivery.
