Why a Laboratory Attritor?

Union Process customers know from experience that the Attritor is one of the most versatile pieces of equipment in their lab. It can be equipped or retrofitted easily and inexpensively with a wide variety of components and accessories. With the Attritor, users can choose wet or dry grinding, introduce inert atmospheres, operate at controlled temperatures, vary grinding speed, overcome product contamination, change media size and type, and get precise energy consumption information, all on the same machine. Results are repeatable from one test grind to another for maximum credibility. Finally, the Attritor is ideal for formulating, quality control, and scale-up studies.

Advantages of Using a Laboratory Attritor:
  • Fast and efficient grinding
  • Numerous options
  • Flexibility
  • Repeatability
  • Scale-up capability
  • No premixing
  • Easy operation
  • Low maintenance
Common Applicatons for Attritors:

  • DSM (mechanical alloying)
  • Food products
  • Chocolate, confectionery
  • Pharmaceuticals
  • Chemicals

  • Agricultural flowables

Research Attritor

The 01 Series Attritors offer users great flexibility as all models share the same column and interchangeable tank design. All models have water cooled jackets for cooling (or heating) and quick water disconnects for removing the tank. These mills are great research tools for formulating, testing, feasibility studies, quality control, and basic research when quantities are small. Results are repeatable. 01 Series Attritors are easy to clean and require no shaft seals.

The 01-HD and 01 Models are designed for media from 1/8" to 1/4". They have shafts with arms and run at RPMs from 100 to 650 and can be used for wet or dry grinding.

The Model 01-HDDM is designed for small media ranging from .25mm (or smaller) to 2mm. These models have shafts with special UP Delta Discs (similar to those used on the Union Process DELTAMILL™) and run at RPMs of 1000 to 4200. The 01-HDDM features a special one-piece cover with charging port and slurry deflection device. This mill is recommended for wet grinding only.

Model 01
The Model 01 is the most basic model in the 01 Series. It comes with a light duty frame, 110 volt AC motor with variable electronic speed, and no RPM reading. A Model 01 cannot be made explosion-proof.

Model 01-HD/01-HDDM
A special 01-HD/01-HDDM combination system is available. In minutes, the RPM of the shaft can be changed from slower 01-HD mode to higher 01-HDDM mode and vice versa. Simply release the belt guard (equipped with quick disconnects), move the belt to an alternative set of pulleys and replace the guard. The appropriate coupling, shaft and cover also must be changed. This system is available with either drive.

Choice of Two Drive Systems
All 01-HD and 01-HDDM Models are available with either of the following two drives:

1. An explosion-proof mechanical variable speed drive system with tachometer.

2. A non-explosion-proof electronic variable frequency drive system. LCD display will be programmed to show agitator RPM, motor AMPS, and motor HP being used. This can be made explosion-proof if the drive controls can be installed in a safe area away from the machine. On the machine is a mechanical tachometer and an operator station with an ON/OFF button and speed potentiometer. An optional explosion-proof readout of motor horsepower is available.

Multi-Tank 01-HD Lab Attritor System

The Multi-Tank 01-HD Lab Attritor System is the ultimate set-up for quality control and test grinding requirements.

  • All tanks (expandable from 2 to 6) controlled by ONE power source.
  • A timing belt assures that all connected Attritor shafts run at the same speed for the same period of time.

Choose standard stainless steel or a metal-free system
with all tanks constructed from alumina, zirconia, or Tefzel®.

1-S Series

Model 1-SDG
1-S Lab Attritor with electronic variable frequency drive and optional Halar®-coated spout
ring, plastic cover, and
zirconium oxide lined tank.

Models 1-S, 1-SC and 1-SD
The 1-S Batch Attritor is a versatile, reliable, rugged laboratory-size machine designed to meet virtually all lab grinding and dispersing needs—either wet or dry. It allows easy and precise scale-up to production size equipment with reproducible results from batch to batch. It is also suitable for small production or pilot plant work.

The 1-S also is available in two additional configurations for specific applications.

• 1-SC – designed for use with tungsten carbide media and supplied with tungsten carbide arm sleeves.
• 1-SD – equipped for dry grinding, includes a metering valve or ball valve and stainless steel cover with floating brush seal for dust control. For continuous operation, disks are added to the shaft.

The Models 1-S, 1-SC, and 1-SD are designed for media ranging from 1/8" to 3/8" and run at RPMs of 100 to 500. All share the following features:

• Variable shaft RPM.
• Adjustable agitator shaft height to accommodate different size grinding media.
• Bottom discharge grid with valve for easy sampling and discharge.
• Tank slides forward and tips 90° for media discharge and fast cleaning.
• Jacketed for cooling (or heating).
• Quick disconnects for cooling water.

Model 1-SDM
The Model 1-SDM is designed for grinding media ranging from 0.25mm to 2mm. The 1-SDM has a shaft with special UP Delta Discs and runs at RPMs of 300 to 2000. It has its own frame, and its tanks are not interchangeable with 1-S, 1-SC or 1-SD models. It has a side discharge screen and valve, and the tank tilts for ease of cleaning. The 1-SDM comes with a special stainless steel one-piece cover with charging port. It does not require a shaft seal.

The Model 1-SDM is available with either a stainless steel, alumina- or zirconium-lined tank. Agitator disks are available in tool steel, stainless steel, plastic or zirconium oxide.

Choice of Two Drive Systems
All models in the 1-S Series are available with either of the following two drives:

1. An explosion-proof mechanical variable speed drive system with tachometer.

2. A non-explosion-proof electronic variable frequency drive system. LCD display will be programmed to show agitator RPM, motor AMPS, and motor HP being used. This can be made explosion proof if the drive controls can be installed in a safe area away from the machine. On the machine is a mechanical tachometer and an operator station with an ON/OFF button and speed potentiometer. An optional explosion-proof readout of motor horsepower is available.
