The edge waviness in hot rolled steel is a common defect. Variables that affect such defect include raw material and machine. These variables are necessary to consider to understand such defect. This research studied the defect of edge waviness for SS 400 of metal sheet manufacture. Defect of metal sheets were divided into two groups. The specimens were investigated on chemical composition and ...

Roller compaction followed by milling of the generated ribbons is a typical dry granulation route. It desirable to be able predict size distribution granules exiting mill based on ribbon properties and operational conditions. Two DEM-PBM approaches for predicting this are compared; direct approach where experimentally determined, an indirect successive change in due each stressing event determi...

Dynamic roller compaction has become the common method for near-surface compaction, because dynamic rollers are much more efficient compared to static rollers. Two types of excitation are mainly used for dynamic roller compaction, the vibratory and the oscillatory roller. In the presented study the differences in functioning, mode of operation and loading the soil are outlined for the two types...

The fault phenomenon of high pressure roller mill gearbox lubrication system is not easy to be find in many cases, the fault of system is easy to be ignored, and it is more difficult to judge with the traditional method. For this reason, the fault diagnosis model of the particle swarm neural network has been established by using actual sample data, determining the cause of fault through the act...

An analysis of construction was conducted in this study, and the guidelines for designing roller mills used commonly agri-food, chemical, power industries were presented. Quick machines required existence adequate mathematical models. Within framework study’s realization, a model developed we presented selected results calculations milling rollers loading from assembly’s mill bowl. The simulati...

In this study we propose a novel monitor hydraulic automatic gauge control (HAGC) system based on fuzzy feedforward controller. This is used in the development of cold rolling mill automation system to improve the quality of cold strip. According to features/ properties of entry steel strip like its average yield stress, width of strip, and desired exit thickness, this controller realizes the c...

This article tells the story of engineering and technology at Castleford Water Mills from the seventeenth century to the twentieth century through the presentation of recently discovered design plans and deeds, supplemented by other historical research. One of Castleford’s mills was operated by Dr Thomas Allinson’s Natural Food Company and therefore retained stoneground milling when fashions fo...
