Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Attrition is the gradual reduction of a workforce as employees leave or retire. This is usually measured by what is called the attrition rate. Most employers want a low attrition rate because it means that employees are satisfied and they don''t have to train new people.

The mill also includes the processes of attrition and impact, although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations. The mill consists of a rotating shaft with four attached parallel knives and a screen occupying one fourth of the 360 degree rotation.

What Is An Attrition Rate? Commonly referred to as a ‘churn rate,’ a company’s attrition rate is the rate at which people leave. If you break it down, it is the number of people who have left the company, divided by the average number of employees over a period of time.

An attrition rate is a metric used to measure employees or customers lost over a period of time who are not replaced. The rate is shown as a percentage compared to the total workforce or customer base. Human resources employees often use an attrition rate to determine the number of vacant or eliminated positions.

crusher, roll crusher, hammer mill and ball mill into smaller or finer particles is called as size reduction [2-3]. The principle of attrition and impact is mainly used here. The process of size reduction, also known as comminution or diminution or pulverization is chiefly achieved by two methods – precipitation and mechanical.
