The Alsto Abrasion Index Tester is designed to enable the abrasion index of a mineral sample to be determined in accordance with F. C. Bond’s abrasion test method.
Based on the Crushability Test (CWi) which was developed by F. C. Bond – modernised with the assistance of pneumatic cylinders for lifting the pendants prior to impact.
Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index.
Alsto Ball & Rod Mills are simple designs intended for long-term operations. The standard drive unit can accept a variety of different barrel sizes and material types.
Alsto Bottle Rollers are designed for batch wet/dry grinding or leaching a variety of minerals and ores.
When size really does matter, Alsto’s Large Bottle Rollers are designed for attending larger volumes when batch wet/dry grinding or leaching a variety of minerals and ores. The rollers can accept barrels or jars in a wide variety of materials for grinding or leaching.
Alsto Bottle Rollers Mk2 Version are our standard Bottle Rollers with a protective cage.
A practical, compact workbench with a stainless steel work area includes a drainage channel at the front and raised borders at the rear + sides for managing spillage. Available in two sizes.
The Alsto Laboratory Flotation Test Apparatus is used primarily for metallurgical test work to establish reagent requirements in production equipment
When dealing with large open tanks on a mine site, sometimes the most practical tool for taking a sample is a simple scoop – at the end of a long steel pole. Alsto sample scoops, made from stainless steel, are available in a variety of sizes and have handles with a range of lengths.
Allows for testing of how different levels of tumbling energy can affect the particle size distribution of the ore. This information is crucial in mining and mineral processing to optimise grinding processes for desired particle size distributions.
