A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The IKA Tube Mill control system is suitable for a wide array of materials with a hardness of up to Mohs 5 and is especially suitable for grinding seeds such as corn and wheat. The unit starts only when the clear hood is closed and the clear grinding chambers allow viewing of materials.
The specific variables to be accommodated and the best strategy to control the grinding process will depend on the actual process circumstances, and the type of mill and drive involved. In modern grinding, ball mills and SAG mills are two types of mill commonly found. Grinding mills Ball mills
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Typically grinding to a particle size in the region of D97 = 10µm, our Air Classifier Mill serves all industries producing fine powders where control of grinding temperature and a narrow particle size distribution is of prime importance. Particle size is controlled by fully adjustable classifier speed, airflow rate and feed rate.

Size control when centreless grinding alumina ceramics was 0.2 μm. Straightness was 0.1 μm in 30 mm. For a range of ceramics, roundness was in the range 0.15–0.2 μm and mirror finish was achieved. The vertical surface grinding machine employed metal-bonded diamond wheels and resin-bonded diamond cup wheels.
the mill can be controlled by a recycle pump to affect the product size distribution, prevent over grinding, and reduce the circulating load from the cyclone. Vertimill Operational Control Final product size is a factor of applied grinding power, flowrate, and slurry density. The effective operation of the Vertimill requires these

The Tube Mill 100 control accommodates larger grinding chambers with a maximum volume of 100 ml (MT 100) . The grinding chamber and cover are made of a transparent material so grinding tests can be observed at any time. The mill can be used for hard (Mohs hardness up to 5), dry and brittle materials.
Combine ABB's variable-speed drive system with advanced process control - ABB Ability™ Expert Optimizer for grinding - to provide maximum mill control. It can be applied to new or existing AG, SAG and ball mills, powered by either ring-geared mill drives (RMD) or gearless mill drives (GMD).
Grinding mill modeling and control: Past, present and future. This paper addresses issues relating to the modeling and control of grinding mill circuits as used in minerals processing, with a particular emphasis on (semi)... Get Price. SAG Mill Control - Mipac.

The problem of designing controllers for efficient control of grinding mills has been studied in the ... The ball mill grinding circuit is illustrated in Figure 2. % Solids 78.9 Circulating Load 474% Advance Control
commonly used control strategies are analyzed and discussed. Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.
There are presently in use many grinding mill control schemes and concepts. In this case, one operating method of controlling the particle size of the cyclone overflows for proper metallurgical results and controlling the level of the cyclone feed sump and new feed rate to obtain lowest unit cost of finished (ground) material which is usually at the maximum grinding mill throughput.
CP3131 Grinding Mill Torque Limiting Control for Single Pinion Mills 3.3 Sensor target installation 3.3.1 Accurate and reliable operation of the Slip Detection feature of the control is dependent upon installation and proper set-up of the proximity sensor targets. Targets and fasteners are included as a part of the control package. Warning
A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al.  is shown in Figure 9.6, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.
In this chapter the mechanisms of wet-grinding mills are considered. The nature of the forces at work, together with a detailed consideration of their interplay and means of control, are discussed in Chapter 6. The general term “tumbling mill” includes the rod mill, pebble mill, and ball mill.
The SAG mill feed is controlled by the mill weight, measured by 4 load cells on the mill bearing system. Therefore if the ore does not grind quickly enough in the SAG mills, the mill weight increases and the control system reduces feed to the mill to maintain the desired mill weight.
