Digital Vibrating Sieving Equipment suitable for Test Sieves of 3 to 18″

The Laboratory Vibrating Sieving Machine is perfectly suitable for the batch and continuous sieving of soft, middle hard, hard and brittle materials. The machine is designed to give precise and reproducible results. Due to the wide choice of parameter combinations it is possible to achieve fast and reliable sieving results in a short time.

Sieve analysis A sieve analysis is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution of a granular material. The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. Being such a simple technique of particle sizing, it is probably the most common.		Adjustment of sieving parameters The required sieving time, Interval function and amplitude can be pre-selected and stored in steps. This is done in a reproducible and comfortable way via the ergonomic operator keypad.

Vibrating Sieve Machine

The LMSM is powered by an electromagnetic drive which has no rotating parts to wear making it maintenance free and extremely quiet in operation. The vibratory action produced by the power unit moves the sample over the sieve in a unique way producing faster more efficient sieving, while the rapid vertical movements also help to keep the apertures clear from blinding.

The 3D Digital’s digital controller is used to set both the process time and the amplitude setting while a further control enables the vibration to run continuously or intermittently. Intermittent vibration improves performance and helps to clear apertures that may have become blocked. The controller will also set the duration of both the on and off times of the vibration. Non-metallic springs and anti-vibration feed are fitted to isolate vibrations from work surfaces and reduce noise levels.

Our Analytical Sieve Shakers the optimal solution for perfect quality control. Particle size analysis gets more and more important and the demands in research and development production and quality assurance are constantly increasing. 911metallurgist.com instruments meet and exceed the high requirements of their customers. All that has to be done is to pour in the sample, put the sieve stack into the shaker, close the clamping device, enter the required parameters and start the sieving process. Due to the unique technology and the design our sieve shakers and test sieves produce accurate, reproducible and fast sieving results in no time. This shows you the operating mode, the innovative technology and the many advantages the 911metallurgist.com high tech sieve shaker has to offer. The superior drive mechanism as well as the sieve acceleration which can be set independently of the power frequency ensures comparable and reproducible sieving results worldwide.

Comfortable handling, digital parameter adjustment and an extremely quiet maintenance free drive make this device very convenient and user friendly. All these features guarantee an efficient work flow and short sieving times. Particles between 20µm and 25mm can be analyzed with the shaker; it is also suitable for wet sieving. The comfort sieve clamping device enables an easier, faster and safer handling. All sieving parameters such as time, interval, vibration height or respectively sieve acceleration are digitally adjustable; the default setting of the vibration height can be switched to sieve acceleration. Sieving with equal acceleration means obtaining worldwide comparable and reproducible results completely independent of operational parameters such as power frequency, loading, age or condition of the unit; an advantage that only 911metallurgist.com Sieve Shakers offer. Additional to this, 9 parameter settings can be stored for routine sieving processes.

The drive produces a 3D throwing motion that moves the sample to be sieved equally over the whole sieving surface. This movement is the result of the electromagnetic drive mechanism that is very effective so that the sieving time is greatly reduced. This patented 911metallurgist.com technology which sets standards worldwide is supported by six leaf springs operating extremely quiet and without wear and maintenance. Furthermore a microprocessor controlled measuring and control unit guarantees a constant vibration height, the external influence is absorbed by the measuring sensor and the data is then transferred to the controller. The controller compares the measured data with the desired amplitude and to adjust the drive to the previously entered parameters. The maximum fall through probability is given when the throw time of the particle corresponds to one period of the sieve bottom vibration, this occurs when the relative speed between particle and sieve reaches it’s maximum. Every period the particles have the possibility to be compared with the sieve mesh and to pass the sieve. The so called statistical resonance is the decisive criterion for an optimal sieve analysis; the corresponding acceleration can be pre-selected in the acceleration mode. When the sieving process is completed the sieve stack can be withdrawn without having to take off the lid completely.

With the integrated interface the instrument can be connected to a PC and controlled with the evaluation software; easy sieve. This program enables you to control the whole sieving process and the subsequent documentation with convenience and accuracy. The software calculates all common particle distributions as well as the characteristic values of the particle size, thus making it possible to present the results in standard presentation forms such as tables and charts. The 911MPESM is calibrated to ensure 100% reproducibility of sieving results not only in one device but among all 911MPESM controlled units, thus the traceability to national standards according to ISO 9000 2000 is given. 911metallurgist.com Sieve Shakers are available in different models in order to support the various needs of our customers. All sieve shakers of the series 911MPESM work with a drive that produces a 3D throwing motion. The difference between the two models is that the 911MPESM+ provides a two times larger sieving surface and deals with heavier sieve stacks of up to 10kg. Different from the 911MPESM200 and 911MPESM300, the 911MPESM400 performs horizontal, circular motions which are particularly suitable for the separation of certain products as milled grain, splints and similar materials. The testing of plastics even requires the circular sieving motions.

The following accessories are available for 911metallurgist.com Sieve Shakers; 911metallurgist.com sample dividers to ensure representative individual samples, comfort clamping device for wet sieving, sieving aids like chain rings, brushes, cubes and balls of different materials. The evaluation software; easy sieve special dryers for the rapid and gentle drying of samples and test sieves, ultrasonic cleaners for the optimal cleaning of test sieves to avoid damage of the sieve mesh. A fully automatic production and extensive optical inspection allows a previously unattained product quality which is also documented by a calibration certificate. Moreover our manufacturing process ensures a high quality design for each and every sieve. This offers many unique benefits, based on individualized laser engraving the sieves are clearly and precisely labeled with full traceability. A maximum stability and optimum sealing is given when used in sieve stacks. The tests sieves are 15% lighter than traditional sieves while at the same time the free sieve area is increased due to high alloy stainless steel a high degree of corrosion resistance and ease of cleaning is provided. The one piece construction and fabric transition without any groves prevents cross contamination.
