CSC Scientific has been producing Sieve Test Equipment for more than 60 years.
The Meinzer II Sieve Shaker is Quiet and Small Enough to Run a Sieve Test in The Lab or Production Office.
Dear Particle Testing Professional,
The Primary Purpose of a Sieve Shaker is to Provide Motion to a Sample in a Test Sieve.
An effective Sieve Shaker creates a sieving motion that presents all the particles in a sieve to all of the sieve openings and assists particles to pass through the sieve openings. This requires both rotary and vertical motion.
This sounds simple enough.
The historic standard for sieve shakers is very very loud. Even with ear protection workers should not be in the same room as a sieve test, when using one of these shakers.
How Did This Happen?
More About Sieve Shakers to Help Find Out How It Happened...
In 1935 a group of engineers and lab people got together to figure out how to standardize a sieve test. Until then every lab did the test its own way. Big problems were happening between suppliers and customers. Angry disputes flared up between suppliers and their customers about who was right on issues of particle size.
The result of this collaboration was ASTM E-11 a standard that told how to make a sieve and how to do a sieve test. Here is a summary of the procedure stated in ASTM E-11.
- Hold a test sieve in one hand.
- Put in a pre-weighed sample in the sieve.
- Now you rotate the sieve with one hand and
- Tap the sieve with the other hand.
In other words Rotate the sieve while Tapping it. This process takes a level of coordination and patience. Even more so when you think about doing the process for four or five sieves sizes.
This was an improvement over the random processes used before ASTM E-11. Because of the patience and dexterity needed to do the process there was still wide variations from test to test.
An enterprising company developed a mechanical machine called the RoTap® Sieve Shaker. The RoTap® reproduced the ASTM-11 Rotational motion while Tapping the sieves with a hammer like device.
This brought about many standards related to the time of the test and the number of taps per minute. Thus RoTap® time and taps became a defacto standard in many industries. Test procedures and test results were compared to this official and/or acknowledged standard.
The RoTap® met the mechanical needs of the ASTM standard and produced repeatable results. To accomplish this the machine put a big strain on the mechanical parts and linkages and operated at a very high noise level.
The standard practice when conducting a test with the machine was to leave the lab or build a large sound proof enclosure. Even with ear plugs the intensity of the sound was unbearable.
With the organization of OSHA, concern for occupational health has intensified. This resulted in new laws, Federal inspections and a search to resolve the high noise problem. More expensive sound enclosures, improved ear protection devices and procedures that called for leaving the room (with attendant lost time) were devised to deal with the problem.
If you have ever used one of these historic machines, you know that it would creep around the room if it wasn't bolted down. You've probably also experience the frustration of frequent breakdowns and lost time for repairs.
Is there a way to deal with OSHA demands, solve the noise problems, stop the wander, and eliminate down time and still deal with the continued existence of ancient standards.?
Over the years several designs were offered that either reduced the mechanical stresses and related maintenance problems, or significantly drop the noise level. Yet the standards persisted.
CSC Delivers A Solution with the Meinzer II Sieve Shaker
More than 30 years ago, CSC Scientific developed a sieve shaker that would be quiet, need less maintenance and produce the necessary motion. It was called the Meinzer. Although a vast improvement in the noise levels, there were limitations in matching some of the standards.
In 2005, the Company started development of a shaker that used new techniques to get a sieving motion that presents the particles to all of the sieve openings and assists the particle to pass through the openings. The result was a rotary and vertical motion that produces results that match the standards developed with the RoTap® machines. The shaker is called the Meinzer II.
The Meinzer II is whisper quiet, does not have hammer-like moving parts , is virtually maintenance free and does not have to be bolted down. Watch this short video to see and LISTEN ...
The Florida Geological Survey (FGS) conducted an exhaustive comparison of the results obtained using a Meinzer II and a RoTap®. Based on this studies results the FGS concluded :
"RoTap® and Meinzer II result in insignificantly different outcomes"
In other words, the Whisper Quiet Meinzer II duplicated the results specified by the ancient standards.
This shaker has:
- QUIET OPERATION - Acceptable noise level for the plant or lab.
- COMPACT SIZE - Only 10" diameter footprint.
- CAPACITY - 10 full hight sieves or 21 one-half hight 8 inch diameter sieves plus a lid and a receiver.
- TWO WAY SIEVING ACTION - Simultaneous vertical and horizontal motion.
- BUILT-IN TIMER - Adjustable 60 minute timer with automatic shutoff.
- EASY TO USE CLAMPING SYSTEM - Unique Quick Release and Quick Load Clamps.
- PORTABLE - Light-weight, 36 lbs.
- MAINTENANCE FREE - No internal moving parts.
- AFFORDABLE
Extrodinary Value of the CSC Meinzer II Quiet Sieve Shaker
You can conduct the test on your desk and carry on a telephone conversation at the same time. Because you no longer need to leave the room when running a sieve shaker test, your staff saves down time. At two to ten minutes a test - What is that Saving???
The Meinzer II is produced with no moving mechanical parts. Consequently , its operation does not put large mechanical stress on the shaker. The unit is essentially maintenance free. Similarly, the Meinzer II significantly reduces mechanical abuse and stress of sieves in the stack -- thus increasing sieve life. These two items alone will produce an early pay off.
The rotating/hammer type shakers require frequent parts replacement that cost several hundreds of dollars per shot. That motion also creates a level of stress that tends to distort sieve frames resulting in the need for frequent sieve replacement.
The Meinzer II creates the sieving motion that presents all particles in a sieve to all of the sieve openings and assists particles to pass through the sieve openings without creating a loud irritating noise and without causing wear on the shaker parts and sieves.
When combined with the elimination staff down time, elimination of shaker caused maintenance and reduced sieve life, saving of thousands of dollars can be realized by the selection of the Meinzer II sieve shaker.
