Nature of Investigation The purpose of this study was to investigate fully the principles of "47 Process" operation so that optimum design of equipment and operating conditions could be established. Phila delphia Process & Methods Protest No. p-l, "47 Process Develop ment Program", was approved and the study undertaken with the following objectives:- 1. Determine the variables affecting quality and through put rates and establish their limitations. 2. Establish optimum design and operating conditions to increase rates and/or improve quality, 3. Simplify design and specify standards of equipment to reduce installation, repair and operating costs. 4. Provide information for placing additional formulas on "47 Process" and the elimination of two-stage grinds on present products, B, Results and Conclusions % Investigation of "47 process" principles resulted in the establishment of the effect of each variable involved in the process. Based on these results, a new design -of equipment was developed and evaluated on a semi-works, 6-1/2 gallon, scale. Scale-up to production size was made and equipment standards specified. This design provides increased rates, higher quality of dispersion and eliminates several high cost items in the in stallation. Maintenance costs also should be substantially re duced. Alterations to present production vessels were developed and evaluated. These modifications can be made at relatively low cost and provide improved operation. It is estimated that the proposed installations will more than double the present average production rates and will enable many products now ground on Ball and Pebble Mills to be made by ''47 Process" at a substantial annual savings. C, Recommendations 1, Install "47 Process" system of proposed design as a regular production unit. Provide close follow-up of ' operation of initial installation and report any de ficiency or improvement.

Origin of Investigation During the years of 1946 and 19-r? a new dispersion technique was proposed by Dr. Seymore Hochbcrg of the Philadelphia Labo ratory's Physical Chemistry Group. The new process was developed in the laboratory stage ur.der the Chemical Division Project, P-159, and the Industrial Engineering Division Study, MX-] 034. Further investigation on laboratory and semi-works scales was continued under the I.3.D. Project, Mi:-1123, and Chemical Division Project, P-2024. As a result ox" these studies ar.d with the as sistance of the Philadelphia Process & Methods Group, ccis new "47 Process'* was placed on a production ba3i3. Utilisation of the process grew rapidly during the years 19^9 ' and 1950 as the advantages of the ne . process became firmly es tablished. During the expansion period. n*, further dev^lrp'-ent work was carried out and efforts wore concentrated or. Installa tions as replacements for ether gxdrains equipment. While initial work had indicated substantial quality improvexen: available, a relatively small number of codes cf hard-to-diiperse colors could be made on a producttiioon scaallee.. Ir. addition, grinding rates were not as great as originally anticipated. Therefore, a special Process & Methods Study was prepared to ?o tablisl. ere principles of operation and determine she optima design of a production unit'. This project was authorized in January, 1951, 3 Process & Methods Study P-1, "47 Process " Development Program. O 3.

DUP030001879 -4 - Philadelphia Plant August, 1952 Process & Methods Study - P-1, Production by '"I7 Process" is now United to 14 .8# of all "Dulux" semi-alkyd and orthodox mill base production. "Dulux" mill b3es account for 86.^ of "47 Process'' production, equlvalent to 22.3/ of the total Divisional "Dulux 1 nil! base production {See Exhibit H) . Although the advances of improved quality or reduced operating costs have been established for the products now dispersed by ''47 Process'1, use of this new method has not been further expanded due to the limitations of the troce3S on difficult- to-disperse codes and relatively poor rates on other more easily dispersed products.

A special test was devised whereby the dispersion of the blade base could be numerically described. The du Pont Differential Colorimeter uas used to measure the re flectance of a 94-line enamel made from the dispersed base.

Alterations to Present Production Equivalent In the course of the experimental program, improved equipment and methods of operation were developed. Several of these modifi cations could be adapted readily to present production equipment at a small investment. So that increased productivity could be realized immediately and experience developed on a production scale these alterations uera made to several 23-3a!Ion production units at Philadelphia. I'oriificaticns thusly evaluated included increased screen area with cha use of a bottom screen and addi tion of a fourth disc to the agitator shaft. An improved screen changing method, developed by one Fort I'aiison riant, was also . incorporated in :ij@se modifications and found vary satisfactory.

Exhibit D shows the effect of DUP030001884 Philadelphia Plant August, 1952 Process 3s Methods Study - ?-l agitator speed on dispersion and indicates a definite tapering-off of the advantage to be gained by increased speed . It would therefore be desirable to set speed at a sufficiently high level ar.d obtain additional power by methods other than further increases in speed. Agitator speed of 300 R?M (a standard motor speed noc requiring a reducer) would be the most desirable agitation speed. o Since car.d is heavier than rest rill bases, a certai* amount of centrifuging action is present in the "47 process" With conventional installations, -l'i3 aclon is generally unimportant.
