BW型板式给料机 Apron  feeder

BW型链板式给料机（简称板喂机）是一种散状物料输送设备，把间歇式给料转变为连续性给料。本厂在引进国外先进技术上全心开发的BW型板喂机，具有牵引力大，漏料少、运行平稳，使寿命长用检修方便的优点。

BW type apron feeder  is knd of machinery for continuously transporting bulky material．It is overall developed on the  basis of importing advanced technology from overseas．It has advantages of large  drawing strength，little material leakage，level operation，long service life and conventenance．

本机采用二点支撑（混合喂料增加中间支点），一端直接置于破碎机上，工艺布局简单，节约土建费用。

尾部装置采取特殊设计，适用于多雨潮湿地区，不会因粘湿物料聚积尾部而造成链条出现跳齿现象，影响生产。

尾部有枕木吸震，中部有一定数量特殊吸震拖辊支承，改善大块物料冲击两侧滚轮和槽板的受力条件，提高运行部件的寿命。

特别加强处理的头部罩壳下罩左右是不分开的，因而不妨碍起吊破碎机转子体。

牵引链和承载链分开，动载荷小，提高寿命。

头部装置链轮13~15齿，奇偶数齿分开传动，寿命可增加一倍。

头部装置链轮切割成3瓣齿，不需要拆卸链板，即可更换齿轮，易维护。

本机宽度参数参照F.L.SMIDTH（丹麦）和AUMUND（德国）公司标准设计。

This machine adopt  two-point support (mixed feeding add a fulcrum)one end is put on the crusher  directly,technology arrangement is simpler,saving construction expenditure.

Tail unit adopt  special designing, apply to rainy and humid area, so avoiding chain jumping out  resulting from sticky material accumulating on the tailing to disturb  production.

Having crosstie on  tali to absorb vibration,and some special absorptive absorptive bace-up roller  on the middle,the impacting force to the sides rolling wheel and trough plate  form large lump material are improved greatly to increase service life of  running parts.

The lower housing of  head housing, which is reinforced especially, may be divided into left part and  right part, so, forlifting crusher rotor it has no obstruction.

The traction chain and  the load chain is fixed separately, so,the moving load is small,to prolong  service life.

The head fitted with  sprocket of 13-15tooth, the odd number tooth and the even number tooth is  driven separately, so, its service life may be doubled.

The head fittad with  sprocket with three-split parrs,when replacing the wheel tooth,dismantling  chain plate is ot needed,and maintenance is easier.

Width design parameter  of this machine refers to F .L.SMIDTH(Denmark )  and AUMUND (Germany )  Company standard.
