MILL OPERATIONS
To save fiber when processing hardwood and softwood furnish, Gilman Paper Co. plans to install new Black Clawson pressure screens and a mini-pressure screen in the brownstock screen system at its St. Mary's, Ga., mill. The mill produces bleached and unbleached kraft multi-wall products.
 Siemens AG, Industrial and Building Systems, will provide the drive system for the complete paper machine and finishing equipment. At a production speed of 5,900 fpm, the new paper machine will be the world's fastest. The total installed load with 40 drives will be 28,900 hp for the paper machine and 4,400 hp for the winders. Startup for the new production line is scheduled for spring 1998.
With engineering assistance from Simon Holder Ltd., Lincoln Pulp & Paper Co. has upgraded the stock and water systems for paper machines No. 4 and No. 5 and for tissue machine No. 7 at its Lincoln, Maine, mill. The upgrade includes a redesign of the stock, water, and broke systems to minimize fiber loss, solids and dye to effluent, and off-spec production during grade and color changes.
Procter and Gamble Co. has ordered a second complete tissue machine and auxiliary equipment from Valmet for its Albany, Ga., mill. The new paper machine No. 6 is part of P&G's $180 million investment which will add 65,000 tpy of tissue, towel, and facial products, including Charmin, Bounty, and Puffs. Paper machine No. 5, which was ordered from Valmet in late 1994, is scheduled to start up in the near future.
Liberty Paper Co., Becker, Minn., has commissioned two dewatering screw presses from Vincent Corp. As part of the wastewater cleanup system, the VP-16 presses dewater the tertiary waste streams at this OCC recycling mill.

NEW TECHNOLOGY
Solv-Ex and Raisio test new, high-performance pigment
Solv-Ex Corp. and Raisio Chemicals Oy recently announced that the two companies have formed an alliance for further testing and market evaluation of a new product developed by Solv-Ex for use in the paper industry. The focus of work will be on the use of the product as a specialty pigment for coatings and fillers. Produced from fine clays found in the oil sands of Northern Alberta's Athabasca region, the new product is a synthetic mineral with properties similar to high-value titanium dioxide.
Solv-Ex reports that product development has been underway for almost a year, and that early product tests have been very encouraging. In laboratory and papermaking trials at an industry pilot plant, the new pigment showed excellent performance as a filler in both woodfree and mechanical printing papers under both alkaline and acid papermaking conditions.
In one of these preliminary tests, the new Solv-Ex filler, designated TiO2-S, was compared for brightness contributions against filler content with precipitated calcium carbonate (PCC) and titanium dioxide (TiO2). In the uncoated woodfree sheets, TiO2-S performed better than PCC and showed excellent results when compared to the more expensive TiO2.
Since the alliance with Raisio includes an aggressive development schedule, Solv-Ex expects an acceleration toward commercial production if testing proceeds in line with expectations.
