PEARL MILL

ENGINEERING AND OPERATING PRINCIPLES

Continuously Processes The Pre-Dispersed latex pigments paints Printing Ink In Conjunction With An Intermediate Storage Tank, Pre-selected Parameters Are Held Constant During The Entire Operational Period Guaranteeing That The Best Possible Throughput Rate Is Set.

FEATURES AND BENEFITS OF S F PEARL MILL

High Grinding Efficiency, Enclosed Design, Double-Acting Mechanical Seal, Optimal Adjustment Of Bead Charge, Wear-Resistant Grinding Chamber, Integrated Lifting Device, Multiple Cooling, Our pearl mill has special rotor design for use with various grinding media glass beads, zirconia, ermil, zirmil-y, zirmil-ce, rimax etc, ranging from size 0.5mm to 2.5mm. Please note the Quality of Super Dispersed Slurry milled by Pearl Mill is found to be Average of 1 to 2 Microns, Which much of higher quality / standards than ball milled for 72 hours to get just 5 to 8 Microns. Further Sulfur , as experienced by Ball Mill users in past as difficult chemical to be milled for getting good dispersions , has been found to be very good dispersed , after Pearl Grinder Milling. The reduction in the operation costs are high due to the very strong saving features , makes the mill A FREE OF COST MACHINE IN ONE YEARS OPERATIONS. THUS THE MACHINE BECOMES A PROFIT CENTRE / GENERATES PROFITS DUE TO ECONOMICAL OPERATIONS , IN THE SUBSEQUANT YEARS .  
( one of the main features of the mill is the high productivity of  as can be easily seen calculated from above production data furnished by us. One pearl grinder mill , very easily replaces 8 to 16  ball mills.
Thus having tremendous advantages of hitech mills over the conventional mills like Ball Mills / Attritors etc.

S.F. PEAR MILL suitable for grinding low medium high viscosity material between 50 CPS and 5000 CPS Thixotropics and products with highly pigmented system.

Body

This machine will have the following items. Sturdy Mild Steel Heavy duty Plate frame Body of 10mm thk for the Mill.

Grinding Disc

Grinding Disc will be of Polypropylene having 10 Nos of Disc for Pigment Grinding (Water Based). Or Range Of Grinding Disc Available Will Be Of Special Wear-Resistant Steel, Hardened Chrome Steel Discs, Stainless Steel (304 Or 316), Hastelloy C , Polyurethane , UHMW Polyethylene , Polyamide (Nylon®).

Main Shaft

Main Drive Shaft will be of material of construction will be Stainless Steel 304.

Grinding Container

Double walled Cooling Efficiency Is Enhanced Through The use Of a Two-Zone Spiraled Jacket. The Spiral Design Creates These Desired Effects: cooling to the Entire Chamber; Greater Temperature Control Due To Increased Surface Area; And Reduced Pressure Drop by the Use of Two Inlet and Discharge Ports. Inner cylinder is stainless steel 304 10mm and 3mm stainless steel 304 jacket. To control temperature use of chilled water is required.

Sealing

Shaft sealing is carried out by a single-action mechanical seal with rotor and stator of Tungsten Carbide. Rinsing an of the mechanical seal is provided by a glycerine-flow closed circuit system by a Teflon Lip-seal, glycerine also water – cooled.

Separation for the grinding beads

SCREE TYPE Outlet Screen For Separation Of Grinding Media From Slurry. Grinding beads size .5 mm to .7 mm.

Main Drive Motor

Will be -- HP 3ph, 1440 RPM, and 440V / 380 V 50 Hz / 60 Hz, of any standard make. Feeding pump will of Screw Type or Diapharm type pump having M.O.C. SS-304. Mechanical Seal rinsing pump motor is 0.18kW.

Agitator Disc Peripheral Speeds

The speeds are 10 m/sec, fixed type ‘C’ sec motor pulley.

Feeding Pump: Screw Pump of Size ½” or 1” Diapharm type. M Seal Rinsing Pump ¼ Inch / Centrifugal Type.

Materials

Material parts which are subject to wear and in touch with the product are made of specific hardened steel and stainless steel.

Control Panel

Control panel mounted separately on the side of  machine body is composed of Fully Automatic Star Delta Starter for main. Start-stop buttons for motors; ON_OFF switch, Volt Meter, Ammeter; emergency stop button etc.
