figure 2 illustrates the main effects plots and explains how different ball mill process factors affect the response characteristic. it is noticeable that the main effect exists because different levels of factor affect the response differently. since there are three levels for each process factor, hence it is discovering that one level .
In face milling one of the most important parameters of the process quality is the roughness of the machined surface. in many articles, the influence of cutting regimes on the roughness and .
In the presented paper attention is paid to the ball mills, semi-autogenous and autogenous mills. the applications of mills are reviewed. the most used working regime of ball mills is described. the factors, affecting the milling process are examined. the factors, related to required energy for grinding: rotational speed of the drum, type of the mill shell and drum filling factor are shown.
a ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. the balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
the ball mill equipment is mainly suitable for grinding and production in industries that require milling, and plays a very important role in my country's basic industry. it plays an important role in the process of processing various industrial raw materials in the production line. in the operation of the ball mill, the working efficiency has certain influencing factors.
factors affecting size reduction abrasiveness: abrasiveness is a property of hard materials (particularly those of mineral origin). it may limit the type of machinery that can be used. during the grinding of some very abrasive substances the final powder may be contaminated with more than 0.1 percent of metal worn from the grinding mill 13 .
this wet mass hampers the milling process. ex: potassium carbonate. closed system such as porcelain ball mill is used. moisture content – presence of more than 5% moisture influences hardness, toughness, stickiness of substance, in general material having moisture content below 5% are suitable for dry grinding and above 50% for wet grinding.
Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. the milling process requires a milling machine, workpiece, fixture, and cutter. the workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached .
