It cannot preferably be removed in front-end processing link, therefore bigger to the abrasion of grinder hammerhead, strong impact is but also broken
Broken owner's axis service life reduction, cracking hammer head and main shaft high frequency of replacement, seriously affect normal operation.Meanwhile broken is one
The technique that kind consumes energy very much, causes the increase of processing cost；
(3) it is inorganic be mingled with it is more.The separation of organic matter is wrapped in the containers such as polybag, box and bottle mainly by being crushed
In organic kitchen separated under the fragmentation of hammer leaf.Glass, ceramics and brick but during broken, in kitchen
It is watt equal to be also broken, a large amount of blocky and particulate inorganic impurity, such as sand, cullet, broken ceramics are produced, after this just gives
Continuous processing links, which are brought, to be seriously affected, in order to remove these impurity, it has to add desanding device.
(4) organic matter loss is larger.The acquisition of organic matter is however a part of organic during broken mainly by broken
Matter can be lost；Big part sorting link before breaking can also lose part organic matter；For desanding and fiber-like impurity, increase
Screw extruder, removal effect is preferable, but organic matter largely loses.
