PLD Bag-pulling automatic Bottom Discharge Centrifuge
PLD series bag-pulling bottom discharge scraper centrifuge is a type of new product with fully independent intellectual property independently developed by us. This series centrifuge retains such primary functions offered in the LGZ series as the solid-liquid separation and scraper discharge, and adds such function as to remove the residual solid cake by pulling filter cloth with the removal rate higher than 99%. PLD series avoids crossing and mixing of different batches of separated products, and also eliminates the effects of the residual solid cake on the basket wall. It is mainly used in the solid-liquid separation process of crystallized materials in such industries as pharmacy, food, gourmet powder and chemistry.
Material to be separated enters into the basket of the centrifuge that is rotating at high speed through a feeding pipe, and under action of the centrifugal field, the material passes through the filter cloth (screen) for filtration. Then the liquid phase discharges through the discharge pipeline, while the solid phase is retained in the basket. Feeding stops once the basket is filled with the material, then wash the solid cake, and discharge the washing liquid through filtration. The centrifuge continues to rotate to spin-dry the solid cake. After the solid cake meets the requirements for separation, the centrifuge reduces its speed, and removes the cake by means of the scraper, then discharges the cake out of the centrifuge. The centrifuge further reduces its speed so that the pneumatic pulling bag device moves reciprocally to shake off the residual solid cake, thus completely eliminating the solid cake.
In addition to all main features of the LGZ series centrifuge, the PLD series centrifuge features as follows:

In addition to all main features of the LGZ series centrifuge, the PLD series centrifuge features as follows:
|
|
Removing the residual solid cake by bad-pulling method. Eliminate all solid cakes left over the process of scraper discharging through reciprocal movement of the pneumatic pulling bag deice.
