60 Inches Dia Bottom Discharge Machine
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. Technical Specifications

The Process
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.
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 cakes sensor is heard.
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.
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
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.
Heel Removal
The gas pressure is applied on the jet nozzels provided outside the basket. The basket is run at SLOW SPEED with scrapper in cut position. The jet pressure dislodges the layer of cake.
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.
