steel cradle

From the time NORTON first started building pulpstones, we have been using wooden cradles to transport our pulpstones worldwide. Recently, we started using steel cradles on all pulpstone shipments. The change came as a result of an International Plant Protection Treaty to reduce the risk of spreading quarantine pests associated with wood packaging materials.

Our plant studied two ways of complying with the treaty before deciding to go to with steel:

  1. Heat treating the wood using existing ovens. This idea turned out to be too costly and would have required additional oven capacity.
  2. Fumigating the wood just prior to shipment. This idea, although cost effective, presented heath concerns for the employees and was therefore quickly rejected.

Robert Fox, local union president, came up with an effective alternative: Build the cradles out of steel. Working with a local steel fabricator, StelCrete, a prototype was built and tested within 2 months of the initial idea. Surprisingly, the cost of the steel vs wood was only marginally higher. The steel cradles also weigh a little less because they are much smaller than wood cradles.

Two major advantages of steel over wood became apparent:

  1. The steel cradles are certified by a structural Engineer to support pulpstone weights. Pulpstones range in weight from 5000 to 25000 lbs (2000 to 11000 Kg). Wooden cradles on the other hand were over designed to compensate for possible cracks that would reduce the structural integrity of the cradle.
  2. The second advantage was cube utilization. Because the steel cradles are smaller and easier to handle, international shipments in containers would in some cases fit three stones instead of two.
There has been nothing but positive response from those customers that are now receiving steel cradles. Plant workers prefer using these cradles because of the ease in handling and compliance with the treaty is no longer an issue, thanks to Robert Fox's idea.

May 2005

Saint-Gobain Abrasives, in collaboration with Norske Canada, Port Alberni mill, will be running a trial on BT pulpstones with Western cottonwood species on Great Northern grinders. The trial will compare BT with same specification standard surfaced pulpstones. Trial will be jointly supervised by Saint-Gobain and mill personnel. Purpose is to compare pulp quality and performance of BT in this environment. Mill is to prepare a paper/report for presentation at the Mechanical Pulping Committee Meeting in September 2005.

November 2004


Saint-Gobain Abrasives, in collaboration with a Québec mill, will run a trial of its Excalibur burr. The ExcaliBURR will be compared to standard burrs from all suppliers. Purpose is to ascertain pattern quality and burr performance. Trial is scheduled for December 2004.

November 2004


Saint-Gobain Abrasives, in collaboration with a Mid West US PGW mill will run an extensive comparative trial of its new WJ (Water Jet) pulpstone, developed to withstand water jet pressures of up to 36000 psi. Mill will compare, over a one year period, wear as compared to standard specification stone of equal grit size. Mill will prepare a final report for publication.

Saint-Gobain Abrasives/Customer collaborative mill trials, V21 Bond, Surface Configurations: UPDATE

All mill trials for 1997 are completed, pulp testing is finished and the results are presently being collated by Saint-Gobain Abrasives and the CSPP(Centre Spécialisé en Pâtes & Papier) of Trois-Rivières, Québec. The trials were conducted in four mills on Atmospheric Grinders, Chain type & Hydraulic, as well as PGW.

Preliminary Conclusions: There is little significant change in Pulp Quality with the use of V21 Bond, nor is there with the minor change in surface configuration of Helical Grooves. This is also true for the BT when the attachment holes are news open; it is believed that the increase in surface open area produces a corresponding increase in Grinding unit pressure, thereby virtually equalizing Pulp Quality Values with standard surface norms. In the PGW V21 Bond mill trial, the results show a 12% increase in production with a 8% decrease in Specific Energy Consumption. The Chain Grinder Grooved Pulpstone trial shows increased production with decreased SEC.

A Final Report of this exhaustive technical project is expected to be complete by January 15, 1998, and will be available for review by interested mills.

Bolt-Through (BT) Pulpstone Engineering Analysis completed.

Iron Mountain, Michigan - At the Annual PGW Seminar held in Iron Mountain in October, Saint-Gobain Abrasives revealed the results of a Finite Element Stress Modeling study conducted at its Research Division in Northboro, Mass. earlier this year. With the ANSYS finite element software package, A fully 3D linear elastic geometric representation of the pulpstone assembly was developed and used to compare the BT segment attachment to conventional threaded WRB attachment. The analysis included detailed study of Flange Clamping Stresses, Rotational Stresses, Stud-Cage Assembly Torque Stress, Segment Thermal Mismatch Stress (Inner & Outer Segments for BT& WRB).

Conclusions: Pulpstone Flange Clamping generates stresses far below the strength of the concrete. However, Clamping plus Rotational Loading can generate stress sufficient to de-bond end segments, indicating that care must be taken to apply the correct clamping pressure when mounting the Pulpstone. The combined thermal-mechanical stress results indicate that the BT attachment design is significantly less failure prone than the conventional WRB design.

These conclusions were supported by a recent US PGW mill trial comparing a BT pulpstone with a standard construction pulpstone. The BT performed exceptionally well and was recently removed from the Grinder after 37 months service, a record pulpstone life for the mill. At change out, the pulpstone still had over .500" of remaining useable abrasive; it had been decided to replace it since other work was required on the Grinder. The mill has installed BT Pulpstones on the other three PGW Grinders.
