At FRITSCH you will find for each individual type of sample preparation sample quantity and material the suitable instrument Like our high-performance mills which work with various comminution methods Or our optimal solutions for efficient sieve analysis and exact reproducible results


The Attritor is often referred to generically as a stirred ball mill The operation of an Attritor is simple and effective The material to be ground is placed in a stationary tank with the grinding media Carbon steel stainless steel chrome steel tungsten carbide and ceramic balls are commonly used media The material and media are then agitated by a shaft with arms rotating at high


This study was carried out in a standard bond ball mill 305 mm x 305 mm size in mineral processing laboratory in the mining engineering department at King Abdulaziz University KSA as shown in Figure 2 Grinding media of steel balls weighing 20 5 kg has been used The details of the mill

Industrial Ball Mills: Steel Ball Mills and Lined Ball

Ball Mills Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's The basic construction of a ball mill is a cylindrical container with journals at its axis

steel ball consumption in ball mill

How to reduce ball abrasion of ball millcement In the grinding operation the consumption of ball mill steel ball is very large about 10 times more than the loss of ball mill lining order to make up for the loss of steel ball and keep the ball size unchanged in the mill it is necessary to add steel ball

AMIT 135: Lesson 7 Ball Mills Circuits

For overflow ball mills the charge should not exceed 45% of the mill volume For grate discharge mills the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R i e

Comparison of energy efficiency between ball mills and

The measured Bond ball mill energy consumption in relation to mill revolution from the data of various ore types and feed sizes (Shi et al 2006) A similar approach was taken for the stirred mill tests with the net energy consumption

Relationships between comminution J energy and product

The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load The standard procedural outline of the test is stated in (Bond) 1961 The work index for a ball mill Wi is then calculated from the following equation [7] where P is the closing sieve size ( m) Gbp is the grindability (net g/rev ) F80 and P80 are the 80% passing size of the
