hyperactivation of bentonite in pelletizing process

KOBELCO Pelletizing Process

Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product pellets and plant equipment, as well as the cost of the plants....

Control of hyperactivation in sperm.

BACKGROUND Sperm hyperactivation is critical to fertilization, because it is required for penetration of the zona pellucida. Hyperactivation may also facilitate release of sperm from the oviductal storage reservoir and may propel sperm through mucus in the oviductal lumen and the matrix of the cumulus oophorus. Hyperactivation is characterized by high amplitude, asymmetrical flagellar bending. ...

Biochemical and immunochemical characterization of boar sperm flagellar protein with role in hyperactivation/capacitation process.

Investigations on specific and functionally active sperm antigens could bring about the elucidation of the mechanisms of gamete interaction and help the search for new approaches in prognosis and regulation of fertility. Previously, we reported that the monoclonal antibody (Mab) 3G4 against capacitated boar spermatozoa was capable of inhibiting boar sperm-porcine zona pellucida binding due to i...

Analysis of Pelletizing of Granulometric Separation Powder from Cork Industries

Cork industries generate a considerable amount of solid waste during their processing. Its management implies a problem for companies that should reconsider its reuse for other purposes. In this work, an analysis of pelletizing of granulometric separation powder, which is one of the major wastes in cork industries and which presents suitable properties (as an raw material) for its thermal use, ...

Sealing Properties of Bentonite Suspensions*

Sealing with waterborne clays is a rapid and low cost method of controlling seepage through porous media whenever the clay source is within economical shipping distance of the sealing site. But more must be learned about this method of sealing before it can be fully utilized. Water impedance of waterborne bentonites, as measured by water loss in the filter press test, was correlated with their ...
