The main factors affecting the working performance of the hammer mill are divided into three categories: the crushed material, the crusher itself and the supporting equipment. 1.Influence of crushed material. Different kinds of raw materials, the seed structure and physical properties will be a certain difference, the difficulty of crushing

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor. The paper will propose

An investigation of the factors which affect lead time in spinning mills producing carded and combed counts is reported. Data were collected from 27 mills producing 40 Ne Carded Yarn and 9 mills producing 40 Ne Combed Yarn. A number of 13 parameters which affect lead time were identified and they are FQI (Fibre Quality Index), Roving Production, CSP (Count Strength

Jan 11, 2016 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.
