Vibration mill. Twin- and three-tube vibrating mills are driven by an unbalanced drive. The entire filling of the grinding cylinders, which comprises the grinding media and the feed material, constantly receives impulses from the circular vibrations in the body of the mill. The grinding action itself is produced by the rotation of the grinding media in the opposite direction to the driving rotation and by continuous head-on collisions of the grinding media. The residence time of the material contained in the grinding cylinders is determined by the quantity of the flowing material. The residence time can also be influenced by using damming devices. The sample passes through the grinding cylinders in a helical curve and slides down from the inflow to the outflow. The high degree of fineness achieved is the result of this long grinding procedure. Continuous feeding is carried out by vibrating feeders, rotary valves, or conveyor screws. The product is subsequently conveyed either pneumatically or mechanically. They are basically used to homogenize food and feed

The second longest single trough belt conveyor is the 26.8-kilometre-long (16.7mi) Impumelelo conveyor near Secunda, South Africa. It was design by Conveyor Dynamics, Inc. in based in Bellingham, Washington, USA and constructed by ELB Engineering based in Johannesburg South Africa. The conveyor transports 2,400t/h (2,600 short tons per hour) of coal from a mine to a refinery that converts the coal to diesel fuel. The third longest trough belt conveyor in the world is the 20-kilometre-long (12mi) Curragh conveyor near Westfarmers, QLD, Australia. Conveyor Dynamics, Inc. supplied the basic engineering, control system and commissioning. Detail engineering and Construction was completed by Laing O'Rourke.[15]

coal fly ash - material description - user guidelines for waste and byproduct materials in pavement construction - fhwa-rd-97-148

After the chemical mechanical planarization (CMP) process, the copper surface is contaminated by a mass of particles (e.g. silica) and organic residues (e.g. benzotriazole), which could do great harm to the integrated circuit, so post-CMP cleaning is essential. In particular, benzotriazole (BTA) forms a layer of Cu-BTA film with copper on the surface, which leads to a hydrophobic surface of copper. So an effective cleaning solution is needed to remove BTA from the copper surface. In this work, a new compound cleaning solution is designed to solve two major problems caused by BTA: one is removing BTA and the other is copper surface corrosion that is caused by the cleaning solution. The cleaning solution is formed of alkaline chelating agent (FA/O II type), which is used to remove BTA, and a surfactant (FA/O I type), which is used as a corrosion inhibitor. BTA removal is characterized by contact angle measurements and electrochemical techniques. The inhibiting corrosion ability of the surfactant is also characterized by electrochemical techniques. The proposed compound cleaning solution shows advantages in removing BTA without corroding the copper surface. (paper)

For linear vibrating screen and high frequency vibrating screen, the poor screening quality may be related to the movement direction of eccentric block, because two groups of eccentric blocks with the same mass need to rotate in self-synchronization and reverse direction to produce a single exciting force along the vibration direction at each instant, which has a fixed angle with the

This study was an investigation on the hydrolytic precipitation of iron from simulated pregnant leach solution (PLS) of nickel laterite atmospheric leaching. The effect of equilibrium pH, temperature and the addition of oxidant on total iron (ferrous (Fe (II)) and ferric (Fe (III)), aluminium and chromium removal was investigated together with the associated nickel and cobalt losses to the precipitate. Systematic variations of the experimental variables revealed 99% of the ferric iron can be removed from solution at conditions similar to those used in standard partial neutralisation in zinc and nickel production, pH of 2.5 and temperature less than 100 C with minimal losses (<0.5%) of both nickel and cobalt. Temperature variation from 55 to 90 C had no significant effect on the magnitude of Fe (III) precipitation but led to a significant increase in aluminium removal from 67% to 95% and improved the filterability of the precipitates. There was no ferrous iron precipitation even at a pH of 3.75 in the absence of an oxidant with its removal (98%) achieved by oxidative precipitation with oxygen gas at pH 3.5. Unlike Fe (III) precipitation, the operating temperature significantly affects oxidative precipitation of Fe (II). Hence, in practical application, the hydrolytic precipitation and oxidation to remove iron must be operated at 85 C to ensure both ferrous and ferric iron are precipitated
