Knife mill operating factors effect on switchgrass particle size distributions.
Biomass particle size impacts handling, storage, conversion, and dust control systems. Switchgrass (Panicum virgatum L.) particle size distributions created by a knife mill were determined for integral classifying screen sizes from 12.7 to 50.8 mm, operating speeds from 250 to 500 rpm, and mass input rates from 2 to 11 kg/min. Particle distributions were classified with standardized sieves for ...
متن کاملParticle size distribution of workplace aerosols in manganese alloy smelters applying a personal sampling strategy.
Air samples were collected by personal sampling with five stage Sioutas cascade impactors and respirable cyclones in parallel among tappers and crane operators in two manganese (Mn) alloy smelters in Norway to investigate PM fractions. The mass concentrations of PM collected by using the impactors and the respirable cyclones were critically evaluated by comparing the results of the parallel mea...
متن کاملAccuracy of size distributions obtained from single particle static digital image analysis
Image analysis has made decisive breakthrough in the recent years to become a reference technique in the field of combined size and shape analysis of particles. Thanks to full automation of the particle dispersion and the individual particle imaging process, productivity of the instrument is no longer a major drawback. However the question of representativity of analyses has not been discussed ...
متن کاملGrounding and Results of Person Oriented Online Monitored Particle-size Sampling for Airborne Particles
To qualify the risks from inhaled particles, the quality characteristics should as well be know as the various regions where the particles will be deposited in the respiratory tract. This means that the inhalable, thoracic, respirable, extrathoracic and tracheobronchial conventions of the airborne particles should be known as an outcome of the measurement process. The personal online measuring ...
متن کاملMass size distributions of elemental aerosols in industrial area
Outdoor aerosol particles were characterized in industrial area of Samalut city (El-minia/Egypt) using low pressure Berner cascade impactor as an aerosol sampler. The impactor operates at 1.7 m(3)/h flow rate. Seven elements were investigated including Ca, Ba, Fe, K, Cu, Mn and Pb using atomic absorption technique. The mean mass concentrations of the elements ranged from 0.42 ng/m(3) (for Ba) t...
