皮帶運輸機 把 灰袋送進開包機進料口, 進料口備有除塵接口可避免灰塵四溢. 灰袋经入口墮進超高付荷的無軸羅旋.一般較薄的袋身經此碰撞已爆烈開. 多層包裝的紙裝或膠質包裝袋也会被緩慢轉动的無軸羅旋及其鋒利的葉面和開包機的內璧以剪刀式把包裝袋割開.

A belt conveyor feeds bags into the inlet port which is covered by a dust collecting hood. The bags drop from the belt on to an extra-heavy-duty spiral screw. Thin bags will burst open just through the impact. Bags with multiple layers or those made of elastic plastic material are pulled in by the slowly turning screw and ripped open through a scissor effect between screw and trough. This effect is increased due to cutting knives applied to the inside trough wall and to the screw fighting.

At the same time the broken bags are conveyed into a revolving screen. The bag contents fall through the screen mesh into a collecting device mounted on the outlet of the machine. Paddles applied inside the screen drum repeatedly lift up the empty bags. In this manner the bags are liberated from remaining material. The inclination of the paddles helps the bags move towards the screen outlet where they drop into the built-on bag compactor which consists of a heavy-duty screw conveyor and a compaction chamber. The compressed bags are slowly pushed into a polythene hose which must be periodically unbound and cut off.



De-dusting is taken care of by an integrated fan operated, air jet cleaned dust collector placed on top of the screen housing.
