Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More

Astrain gaugebasically works on the principle of a simple metal conductor wire that tends to have an impact on its length crosssectional area and resistance due to applied stress this is due to the fact that the length of the wire is directly proportional to the resistance of the wire and inversely proportional to its crosssectional area as per the following equationRead More
Types ofstrain gaugesmechanicalstrain gauge mechanicalstrain gaugesare among the most straightforward in the way of making and measuring the method of measurement consists of measuring the elongation of the blades and reading this value on a scale magnified 1000 times transmitted by means of mechanical leversRead More
