About Attritor Mill
Attritor Mill is also called Stirred Ball Mill, it is a unique machine with high performance for dry and wet material grinding and blending with the use of modern techniques. It is a fast, powerful and efficient method; the advantage of this mill is that it ensures that grinding media is in action all the time which results in much faster action. A casting slip can be performed in one tenth of the milling time required in a conventional Ball Mill.
With the consistent performance in the steel plant manufacturing, S. F. Engineering Works has carved a niche in the market and is known as a leading manufacturer and exporter of Attritor Mill. This machine is widely used for blending, grinding, milling of all viscous liquids. The machine is highly recognized for its distinctive features. It is available in the market at a very competitive price and customization is possible as per our patron requirement.
Features:
- Robust construction
- User friendly functions and less power consumption
Operating Principle:
- The machine operates on the principle of an Agitator Bead Mill
- Agitator arranged vertically is equipped with agitator pegs
- Ideal flow condition is reached through the combination of optimally arranged agitator pegs and the hemispherical grinding chamber floor
- Circulation grinding ensures exact reproducibility and high product homogeneity
Working of Attritor
Working of Attritor is very simple and effective; the material which has to be ground is placed in a tank with grinding media. Stainless steel, carbon steel, chrome steel, tungsten carbide and ceramic balls are the commonly used grinding media. It is then agitated by a shaft with arms rotating at high speed, this causes media to exert shearing and impact forces on the material resulting in extremely fine material measured in microns and is distributed on a very narrow curve. The laboratory Attritor works ten times faster than the conventional ball, pebble or jar mill. It is compact and vertical which requires minimal space. Adding any ingredient or taking samples can be done at any time.
Construction

- Electrical panel consisting of ammeter, voltmeter and switches
- Drive unit is enclosed in steel cabinets
Efficient Design and OperationBuilt for industrial performance, this Attritor Mill features a robust mild steel frame, horizontal rotation, and a well-crafted agitator shaft fitted with arms/blades. The drums stainless steel lining ensures longevity and compatibility with diverse materials, while its variable speed drive allows operators to tailor grinding intensity. Suitable for both wet and dry processes, it is ideal for fine grinding and uniform dispersion in various industries.
Safe and User-FriendlySafety remains a priority with the Attritor Mills interlocked lid and emergency stop switch, ensuring operators can work confidently. The batch feeding system and bottom valve discharge streamline both loading and material removal. Mobility features like mounted castors make relocation hassle-free, and its moderate noise output (below 80 dB) contributes to a comfortable work environment.
Versatility Across ApplicationsThis mill is well-suited for industries requiring precise particle size reduction and thorough mixing, such as paints, pigments, inks, and coatings. Its wide capacity range (50500 liters) and ability to handle bead sizes from 2 mm to 10 mm make it adaptable for small-scale or large-batch operations. Manual control offers flexibility for a variety of production demands.
FAQs of Attritor Mill:
Q: How does the stainless steel lined drum enhance the grinding process?
A: The stainless steel lining offers excellent resistance to corrosion and wear, ensuring the mill is suitable for aggressive materials, particularly in paint, pigment, ink, and coating production. It also facilitates easy cleaning between batches and maintains product purity.
Q: What are the benefits of the jacketed cooling system during milling?
A: The jacketed cooling system efficiently dissipates heat generated during grinding, which prevents temperature-sensitive materials from degrading and ensures the consistency of product quality throughout the batch process.
Q: When should I use this Attritor Mill for batch processing?
A: The Attritor Mill is best used when you need controlled, repeatable fine grinding or dispersion in moderate batch sizesfrom 50 to 500 liters. It is ideal for operations where flexibility and high-quality mixing are essential, such as in specialty chemical or paint production.
Q: Where is the discharge point located, and how is material removed from the mill?
A: The mill features a bottom valve discharge, allowing for straightforward and efficient emptying of the processed material once the grinding or dispersion cycle is complete.
Q: What kind of materials and processes is this mill suitable for?
A: Designed for wet and dry grinding, this Attritor Mill handles a variety of materials including paints, pigments, inks, and coatings. Its agitator shaft and bead/media size range ensure effective size reduction and homogeneous mixing.
Q: How does the safety system protect operators during use?
A: The mill is equipped with an interlocked lid and an emergency stop switch that immediately halts operation in case of any unforeseen event, greatly reducing accident risks and safeguarding the user.
Q: What are the main benefits of the mills mobility and control system?
A: Mounted on castors, the machine can easily be moved to different processing areas. The manual control system and variable speed up to 1200 rpm offer operators enhanced flexibility to achieve optimal grinding results tailored to specific process needs.
