Particle Size Analysis

Challenge

  • Pharmaceutical and food industries product quality is affected by variations in the particle size of materials.
  • Material handling processes are impacted by the size and shape of particles
  • Process development is restricted by variations in the particle size of materials. 
  • Choosing personal protective equipment for protection against very fine particles.
  • Selecting the correct filtration medium to recycle wastewater to meet environmental standards.
  • Sedimentation rates of particles in water systems can adversely impact on flora and fauna.
  • EPA and other regulatory bodies require characterisation of stack emissions and discharges.

Solution

HRL provides an extensive range of fibre resource assessment services specifically tailored to meet the needs of clients who own fibre resources or who are involved in manufacturing pulp and paper.  Late in 2010, HRL acquired the specialist testing equipment which was used by the CSIRO to provide fibre resource assessment services to Industry. HRL also secured the services of Christine Hicks, an expert with over 15 years' experience, who worked in this area for the CSIRO. The acquisition complements HRL's extensive materials assessment services.

The comprehensive range of resource assessment services HRL offers resource owners and the pulp and paper industries includes wood and a range of non-wood fibres. Non-wood fibres that can be assessed include bagasse (sugarcane residue), straw, kenaf and hemp resources often used in developing countries.

Specific fibre resource assessment services HRL offers include determining:

  • basic density
  • pulp yield
  • chemical and semi-mechanical pulping
  • chemical composition
  • chemical and physical properties
  • paper properties

HRL fibre resource assessment services can be used:

  • as part of tree-breeding programs
  • to determine the value of a timber or other fibre resource
  • to determine properties of the resulting pulp or paper
  • to maximise process efficiency and therefore profitability
  • to provide technical support

Case Study

Wastewater treatment

As part of a project aimed at reducing the environmental impact of a large industrial operation, HRL investigated the wastewater generated by the plant. Advanced chemical and physical analysis techniques were applied to examine the properties and behaviour of the suspended materials in the wastewater. This enabled our team to develop an effective strategy to improve the plant's water treatment system. Not only did this provide significant reductions in the cost of treating the wastewater, it also assisted the company to meet regulatory requirements.

Additional Services

  • ICP-OES
  • XRD analysis
  • Infra-Red (IR) and UV-Vis Spectroscopy
  • Pyro-probe GCMS
  • Density (apparent, true and bulk)
  • Surface area
  • Pore volume distribution (Hg intrusion porosimetry)
  • Rheology (viscosity)

Benefits Include

  • Savings in milling costs by the improvement of the opera tion of milling and blending circuits.
  • Consistent product quality.
  • Meeting of quality control standards set for domestic and international markets.
  • Accurate decisions relating to processes can be made first time, saving money and time.
  • Protection of the safety of the client's people and the environment.
  • Optimisation of processes to fulfil manufacturing specifications by the optimisation of particle size.
