BOTTOM DISCHARGE TYPE (DOME OPEN) CENTRIFUGE
The Pharma and the Fine chemicals Manufacturing sectors have to face the challenge of impurities below PPM (parts per million) levels. The clean centrifuge is must with every new batch.
Ace offers full dome opening machines in its entire range of basket sizes.
The simplicity of the Bottom Discharge arrangement is also taken care of - The Single-point Cake Discharge with Teflon Sweepers, the heel removal the hydraulic scrapper, the cake sensor, the zero speed interlock, the safety switches, The Anti Vibration Tripper, the cGMP version are all apart of the ACE bottom discharge centrifuge. The dimensions of the machine and the HEADROOM for basket sizes 24” dia to 72” dia are given below.

Note : The maximum cake capacity of basket is based on the mechanical design calculations.
Other restrictions such as density, viscosity and other characteristics of the material handled may result in
lower outputs.
Note : Dimensions and specifications are subject to change without prior notice.
a) Feeding: The slurry has to be charged through the feed pipe. The basket speed is almost half of the full speed Cake is taken with feed valve to control the flow rate of feed to ensure complete filtrate discharge. |
 |
 |
b) Cake Sensor: The cake sensor gives the indication of cake filling up to the basket rim. The feed must be stopped if hooter sound of cake sensor is heard. |
c) Washing: The cake should be washed free from impurities at a little higher speed than the feed speed. When discharge is free from impurities, the basket speed is raised to the maximum. The drying of cake is maximum. |
 |
 |
d) Dynamic Braking: It is achieved by pressing of the STOP button of the control panel. The basket comes to a stand still within 200 seconds. |
e) The Scrapping: The Basket is run at a minimum possible speed. The hydraulic power pack is switched on. The scrapper is rotated around the scrapper shaft. The Cake is cut and discharged through single opening below the body. The scrapping takes about 30 minutes. |
 |
 |
f) Heel Removal: The gas pressure is applied on the jet nozzels provied outside the basket. The basket is run at SLOW SPEED with scrapper in cut position. The jet pressure dislodges the layer of cake. |
g) Dome Opening: The Scrapper is taken back to neutral position. The dynamic brake is applied to bring basket to stand still. The dome LBD locks are released. The dome is opened with HYDRAULIC Power pack lever. The cleaning of the body is easily done. |

The A.P.I. production and schedule “M” drugs limitations requires time based production with necessary process steps. The independence pf production on human beings may spoil the quality of production. ACE has thoroughly studied all the process steps of bottom discharge centrifuge. The total control of the machine is done electronically. Use of V.F.D. coupled with P.L.C. has opened the gateway of automation. Our flp control system has been incorporated with HMI / MMI. The user can easily get the following time based benefit with our FLAME-PROOF control panel. |
