Services By Handling Problems
Wear and Attrition Testing
Any mechanical devices which involve the motion of bulk solids relative to surfaces will experience wear problems.
Wear in bulk handling equipment may result from impact or abrasion or, as is often the case, a combination of both. In addition, deterioration of metal surfaces can occur as a result of corrosion.
Several areas where abrasive wear is experienced include storage bins and silos, particularly in hoppers operating under mass flow conditions, feeders, transfer chutes, belt conveyors, vibratory conveyors and screw conveyors. TUNRA Bulk Solids offers the following services related to abrasion, erosion and attrition:
Wall Liner Abrasive Wear Testing
The wear properties of a wear liner when abraded with a bulk material sample can be determined by performing time tests in a horizontal circular wear tester.
This wear tester simulates open three body wear with no impact as experienced in hoppers and chutes.
Abrasive wear testing outcomes:
- Determination of wear rate of surface material for specific applications
- Wear surface characterisation and analysis of wear mechanisms
- Estimation of component life based on wear rate
- Selections of materials for maximum component life based on wear mechanisms and wear rate.
- Comparison of wear life of competing available surface materials
Impact Wear Testing
Impact wear testing is conducted using a specialised impact wear tester designed to simulate impact and abrasive conditions encountered in industrial applications.
The tester allows adjustment of the wear plate angle, enabling testing across a range of impact conditions. It is generally recommended to perform tests at multiple angles to capture variations in wear behaviour. A representative sub-sample of the bulk material is typically used as the erosive medium during testing to ensure realistic simulation of service conditions.
Impact wear testing outcomes:
- Determination of wear rates under combined impact and abrasion conditions representative of industry applications.
- Testing at impact velocities of approximately 6 m/s for particle sizes ranging from 5 mm to 30 mm.
- Surface characterisation to identify dominant wear mechanisms (e.g. gouging, cutting, deformation).
- Support for material selection to maximise component life and performance.
- Comparative assessment of wear resistance between candidate and existing surface materials.
Slurry Wear
Slurry wear testing can be conducted for the following outcomes:
- Determination of wear rate based on concentration
- Thickness loss measurement with time
- Assessment of component life
Particle Attrition
The following test options are available to analyse particle attrition:
- Drop test according to the industry requirements
- Determination of percentage degradation
- SEM analysis for qualitative assessment of particle shapes and sizes, as well as surface analysis and characterisation
