Staurolite
Staurolite is a general-purpose mined mineral abrasive used to remove thin coatings, rust, and mill scale. Its sub-angular shape is ideal for applications where a minimal surface profile is required. Staurolite is excellent for achieving a near white finish and is commonly used for new steel applications; including storage tank & tower construction, structural & plate steel blasting, and steel fabrication.

INCREASED PRODUCTION

Staurolite’s higher bulk density and high hardness results in more energy being transferred to the work surface than most mineral or slag abrasives; easily removing thin coatings, rust, and mill scale. Staurolite’s uniform particle size provides consistent coverage and surface finish, increasing production rates.

LOW DUSTING

Staurolite’s durability and low friability produce lower dust levels than most mineral or slag abrasives. Low dust levels improve the operator’s visibility of the work surface, increasing production rates. Lower dust levels also reduce cleanup costs on the work site.

RECYCLABILITY

The low friability of Staurolite allows it to be recycled 3 to 5 times. Unlike most mineral or slag abrasives, Staurolite will not completely shatter when it hits a surface, keeping its relative size. Recycling Staurolite increases profitability by reducing abrasive consumption, and shipping, cleanup, and disposal costs.

Staurolite Screen Analysis

Inhaling dusts from abrasive blasting may result in serious injury, disease, or death.
According to OSHA, only a Type CE NIOSH-certified blasting airline respirator with positive pressure blasting helmet should be used for abrasive blasting.
