Appl. No.:

08/032525

Inventors:

Henricus Renier Gerardus Steeghs - Englewood CO
James John Schmitt - Eveleth MN

Assignee:

Akzo Nobel N.V. - Arnhem

International Classification:

C22B 1244

US Classification:

75772

Abstract:

A process for particulate agglomeration (i. e. , pelletizing) and the product produced (i. e. , pellets) by such processes are disclosed. The process generally comprises a process of agglomerating particulate material, said process comprising commingling said particulate material with a moistening effective amount of water, a binding effective amount of polymer and a binding effective amount of weak acid to produce a mixture and forming said mixture into agglomerates.

C08K003/22

US Classification:

524/431000, 524/424000

Abstract:

Methods for agglomerating particulate material, especially iron ore and iron ore which is difficult or impossible to bind using known binders and techniques, by rendering the surface of the material negative, by chelating interfering elements in or on the material to permit effective performance of the binder, or by using a binding effective amount of a polymeric binder, sodium carbonate, sodium citrate, and, optionally, caustic.

Filed:

Sep 11, 2003

Appl. No.:

10/525274

Inventors:

James Schmitt - Littleton CO, US
Ali Basdag - Hidd, BH

International Classification:

C08H001/00

US Classification:

106003000

Abstract:

The invention pertains to a process for producing iron oxide-containing pellets wherein line iron oxide particles are agglomerated in the presence of an inorganic and/or organic binder and a binder additive which serves to improve the preheat strength of the pellets. The binder additive can be a boron-containing compound or calcium fluoride. The invention is particularly suitable for organic binders.

Filed:

Dec 8, 2004

Appl. No.:

10/582451

Inventors:

James Schmitt - Littleton CO, US
Ronald Smeink - Apeldoorn, NL

Assignee:

AKZO NOBEL N.V. - Amhem

International Classification:

B22C 9/00

US Classification:

164528000

Abstract:

The present invention relates to a process for producing iron ore agglomerates comprising agglomerating fine iron ore particles in the presence of a binder system wherein the binder system comprises a binder and an alkali metal silicate and wherein the alkali metal silicate is present in an amount of between 0.0001 to 0.08 percent by weight, based on the total weight of dry iron ore agglomerate, wherein the binder system is free of synthetic polymer, and preferably comprises carboxymethyl cellulose as binder.

Appl. No.:

5/720816

Inventors:

Philip J. Kast - Madison WI
James F. Schmitt - Marshall WI

Assignee:

Madison-Kipp Corporation - Madison WI

International Classification:

F16N 724

US Classification:

184 15A

Abstract:

A lubricating device for delivering multiple clean shots of lubricant to a moving conveyor or the like, comprises an electric motor, a positive displacement lubricant pump having a plurality of individual cylinders and associated pistons driven by a common shaft, a single revolution clutch coupling the output of the motor to the shaft of the lubricant dispenser, and a sensing and control system actuated by the moving conveyor which at an appropriate time causes the clutch to engage the motor to the shaft of the lubricant pump for a single revolution, causing the ejection of a plurality of individual clean shots of lubricant which are directed to selected portions of the conveyor system by individual conduits.
