Classifier (Rake & Screw)
Rake Type Classifier
-
This type of classifier constitutes Single or Double Reciprocating rake mechanism, which is ruggedly built with structural
steel and is inclined at a specific angle (<Angle of Repose). An array of Linkages with Hinge Pin joints makes it possible for
long rakes to give a uniform & consistent raking action at a very low energy. These robust mechanism is best known for its
trouble free operation for years together.
The Rake mechanism
facilitates higher grit removal
using different Sizes i.e, 305mm,
460 mm , 610 mm , 760 mm ,
920 mm in Single Rake
construction while the capacity
can be doubled using common
drive & duplex Rake. And
lengths ranging from 5 Mtr to 12
Mtr based on the Inclination
angle and submergence in the
trough.
Rake Classifiers are built over
RCC or Metallic Troughs based
on the application
requirements.
Screw Type Classifier
-
This type of Classifier consists of
slow speed Single Screw enclosed
in a half metal trough for positive
material transfer ensuring higher
rate of grit/sand disposal. Screw
Diameter, length and angle of
installation can be more flexibly
designed to suit the application
requirements. Most common sizes are 250mm, 305mm, 406mm, 457mm and 508mm Dia. Screw Classifiers lengths ranging
from 4 Mtr to 9 mtr can be built without any intermediate bearing support.
