Abstract This paper re-considers the foundations of particle size statistics. While traditional statistics consider their data as samples random variables and use methods classical mathematical statistics, here a sample is treated point process sample, suitable form recommended. The whole sequence ordered sizes considered variable in space. Instead distribution functions, intensity functions ar...

The study investigates ibuprofen with wax-like properties as a multifunctional agent (as an active component and as a melt binder). Binding efficiency was compared with granules prepared by wet granulation using polyvinylpyrollidone (PVP K-30) as a binder for micromeritic, physical and mechanical properties such as angle of repose, particle size distribution Carr's index, Hausner's ratio, crush...

The traditional grinding technology of ball mill has many problems, such as high energy consumption, unable to maintain the original crystal shape, and it is difficult obtain quality purity ultrafine powder. high-pressure water jet mineral dissociation a new which developed in response these requirements. experiment shows that strong ability grinding. With increase velocity, crushing effect mor...

  Objective(s): This study was performed aiming to investigate the effect of particle engineering via spray drying of hydroalcoholic solution on solid states and physico-mechanical properties of acetaminophen.   Materials and Methods: Spray drying of hydroalcoholic solution (25% v/v ethanol/water) of acetaminophen (5% w/v) in the presence of small amounts of polyninylpyrrolidone K30 (PVP) (0, 1...

It is important to develop Martian soil simulants that can be used in Mars exploration programs and Mars research. A new Martian soil simulant, called Jining Martian Soil Simulant (JMSS-1), was developed at the Lunar and Planetary Science Research Center at the Institute of Geochemistry, Chinese Academy of Sciences. The raw materials of JMSS-1 are Jining basalt and Fe oxides (magnetite and hema...

DENTAL amalgams constitute a most important and very high proportion of individual tooth restorations. The physical properties of finished amalgams, upon which the restorations depend for satisfactory service, vary with the alloy formulas, manufacturing methods, mixing procedures, and condensation technics. Previous studies of amalgams have established the effects of many variables and the Amer...

Modifying blasting practices to achieve a more suitable mill feed size – which varies according to the crushing/grinding circuit – can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation’s practices, SRK can advise on how value-added blasting will deliver improvements in both mill capacity and overall consistency of performance. SRK employs modelling to...
