IMPACT PULVERISER  (Fineness upto 325 Mesh / 43 Microns)


" Designed as per individual Product requirement
based on our grinding experience "


SINGHASINI Impact Pulveriser's are impact type, high speed, air swept, swing hammer type, multipurpose grinding mills capable of grinding soft to medium hard minerals & chemicals upto the hardness of 2.5 - 3.0 Mohs. The Pulveriser is supplied with a hopper below which is a Star Feeder actuated by a Pawl & Ratchet Mechanism. Fine Grinding is achieved by compression, shear, abrasion, attrition and impact of Hammers on the materials against the replaceable Radial Liners.

The Pulverised Product is sucked by the Strong suction Centrifugal Blower through internal Whizzer Classifier. In between the Centrifugal Blower and Grinding Chamber is the internal Whizzer classifier consisting of blades with tips tapered to confirm the degree of Whizzer Cone. The Coarser material is thrown back into the grinding chamber for re-grinding and only fines pass though it. Fineness can be controlled by clamping the clamp at a suitable position. The entire wearing portion consisting of Grinding Chamber, Whizzer Cone and Centrifugal Blower are lined with replaceable lining plates.

The Function of the High Efficiency Cyclone Air Separator is to separate the Pulverised material from Air which is re-circulated in the Grinding chamber to complete the closed circuit grinding action. Excess Air coming in the system is bled off through Dust Collector.

The main mill is supplied with Automatic Feeder, High Efficiency Cyclone Air Separator & Dust Collector. The material of construction of internal parts of Pulveriser main mill, cyclone air separator & dust collector varies as per individual requirement. The Pulveriser is supplied with Digital (Automatic) Feed Controller for maximum feeding.
