The manufacturer of centrifugal screening machines: MAROBERA
What is a centrifugal screening machine or sifter?
A centrifugal screening machine or sifter is a machine used to separate products of different particle sizes: powders, flours, granulates and even wet or fatty products (up to 50%). It can discern a wide range of percentages of fines. It is ideal for all types of safety screening.
Also called sifters, they are machines for sieving large volumes of product, which classify powdered or granulated particles according to their dimensions, also allowing their control before processing. The product is conveyed to the sieving chamber, where the inclined blades push it by centrifugal force towards the sieve. The fine particles pass through the screen, while the coarser particles do not, and are conveyed continuously towards the sieve outlet.
They have a loading mouth, where the product to be treated enters, with a perpendicular axis with an endless screw that introduces the product into the sieving chamber. It has blades parallel to the axis of rotation that accelerate the product radially by centrifugation towards a cylindrical sieve. The paddles transport the coarse material retained inside, which is discharged through the coarse material outlet. The material filtered through the screen is discharged through the fines outlet.
Centrifugal screens are designed and manufactured to solve classification, dewatering and separation problems.
It is suitable for food, mining, chemical, packaging, packaging, canning, pet food, animal feed, toys, food industry, plastic recycling…
MAROBERA sifters can perform two types of sieving: separation or safety. The first one is used to separate different granulometries of bulk product with poor flow properties, difficult to screen due to its high content of moisture, fat or static electricity. The second is used to remove possible impurities from the finished product.
Models of industrial centrifugal screens
There are four standard models according to capacity and power:
– TC400
– TC650
– TC800
– TC1000
Manufactured in painted carbon steel, stainless steel AISI 304L or AISI 316L.
With various interior finishes according to application: basic (2B pickled), food grade or sanitary.
Some models can combine the features of vibratory and rotary screeners. In addition, an ultrasonic system can be installed for semi-automatic cleaning of the sieve itself.
