UNLABELLED BACKGROUND Historically, acid pretreatment technology for the production of bio-ethanol from corn stover has required severe conditions to overcome biomass recalcitrance. However, the high usage of acid and steam at severe pretreatment conditions hinders the economic feasibility of the ethanol production from biomass. In addition, the amount of acetate and furfural produced during...

Abstract Chemithermomechanical pulp (CTMP) is often used in middle layers of multiply paperboards due to its high bulk at specified strength. Such a CTMP should consist well-separated undamaged fibres with sufficient bonding capacity. The basic objective this work examine the effect refining on bulk, taking into account conditions such as temperature, sulphonation, gap and refiner size. First s...

In this study, the elemental powders of aluminum and copper were initially subjected to mechanical alloying using an attrition ball mill under argon atmosphere to produce an Al-4.5 wt% Cu powder alloy. The WC nanoparticles were then added to the powder alloy and milled in a planetary ball mill to explore the role of the WC nanoparticles on the mechanical properties of the fabricated composite p...

In this research nanoparticles of Nickel (II) Chloride were synthesized and characterized using fourier transform infrared (FT-IR) spectra. Nanoparticles of Nickel (II) Chloride were prepared by using of ball mill device. A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. In the researc...

Pelletizing plant of the Gol-E-Gohar mining and industrial company consists of a burner, a dry ball mill (6.2 m × 13 m), and an air separator. The ball mill consists of a 2 m-long drying and an 11 m-long grinding chambers. The iron ore concentrate is fed to the drying chamber by a feed chute. It was found that when the feed moisture content increased from 1.3% to 3.5%, the throughput decreased ...

The aim of the presented research was to analyze ceramic material based on cordierite as a function activation time and sintering temperature. Three-component oxide mixture prepared (MgO + Al2O3 SiO2 in ratio 2:2:5). To decrease temperature, 10 mass % Bi2O3 added this mixture. mixtures were mechanically activated for 5 240 minutes ball mill. Activated sintered at temperatures 1173-1573K. XRD me...
