Hammer mill nukor group compact and fast to install. the hammer mill is designed to cut hard grains into smaller pieces, essential in an animal feed pelleting line. perfect for grinding maize, cattle/chicken feed. hammer mill for fine-grinding of chips and wood sawdust as well as grinding of pre-crushed recycling chips or wood bark.

Deflection is measured by the strain gauge marked 2. as the mill rotates and the lifter with the sensor dips into the charge, the force acting on the lifter increases, which in turn, causes a deflection. the strain gauge mounted on the leaf spring converts this deflection to an electric signal. this signal is amplified ball mill.

The ovality sensor is a measurement tool for rotary kilns, which measures the changes of the roundness / curvature in the kiln shell during operation. this elastic deformation is called ovality and is primarily present in the area of a kiln tire. the measurement gives accurate information about the degree of mechanical loads in the refractory / kiln shell and allows defining the ball mill.

Ball mill - wikipedia. a ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and paintsball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Jan 09, 2002 the method of monitoring the level of filling of a ball mill which is fed with material to be pulverized and is provided with a drum mounted to rotate on two bearings which are relatively far apart, consists in measuring the weight of the drum using strain gauge weight sensors 11-16 under the bearings supporting the drum of the ball mill and comparing the measured weight to a predefined set ball mill.
