Ultra Centrifugal Mill FM200

Ultra Centrifugal Mill FM200 applies to a wide range of samples. Based on its high efficiency grinding technology and rich accessories, with two-steps grinding of rotating knife - ring screen system ,it can process dry and wet grinding in a very short time for the soft, hard, brittle, fibrous samples.

Sample type:

Soft, elastic, fibrous, water-bearing, oily, fatty, dry sample

Application fields:

Agriculture, environment, soil, electronics, RoHS testing,coal, chemistry, plastics, medicine, feed, grain, dry plants,etc.

Application Examples:

Diversified application, efficient sample preparation:

1.Ecological environment protection:plants (root, stem and leaf, etc.) sample preparation,C.H.N determination .

2.Coal, coatings sample preparation; ash content, thermal measurement.

3.Identify the nitrogen composition and protein composition of feed and food.

4.Secondary fuel, rubbish, plastic, electronic elements, the determination of harmful substance.

The grinding art for special samples:

1.Plastic and rubber samples will become brittle and easy to grind in liquid nitrogen condition.

2.The distance ring sieve and automatic vibratory feeder can be used for grinding heat-sensitive samples such as paint, resin.

3.The rotor and ring sieve with wear-resisting coatings can be used for grinding rigid and corrosive materials such as fertilizers,chemicals.

Working principle:

The Ultra Centrifugal Mill can realize two-stage crushing for samples with the rotor and ring sieves. Samples are fed from the hopper with anti-splashing design. Under the effect of high speed centrifugal force, the falling samples and the high speed rotor generate a giant impact force to perform pretreatment for samples; then the samples are sheared, extruded and rubbed again between the rotor and ring sieves. The sample will enter into the collecting pan when the size is less than the aperture of ring sieves. The two-stage crushing guarantees moderate and efficient grinding results. Due to the high crushing efficiency, the period of samples staying in the grinding chamber is quite short so as to avoid changes of sample natures.

Automatic feed device and large sample receiver:

1.Ultra Centrifugal Mill FM200 can be equipped with an automatic feed device , which can guarantee highly homogeneous grinding results and avoid the risk of sample feed overload.

2.The ground samples are collected in a collecting pan, which is convenient for collection without sample loss and prevents cross contamination of samples.

3.When using a cyclone or a filter bag, the ground samples can be cooled via airflow and leave the grinding chamber quickly via the collecting pan with an exit. If a vacuum cleaner is connected, the process can be faster and more efficient. The cyclone can be used in conjunction with250ml or 500ml sample bottles; for large volume samples, the cyclone with the capacity of 3L or 5L can be selected.

All parts contacting samples can be removed manually without any tools, and it is quite convenient to clean and install such parts.

Features and advantages:

1.Final fineness less than 40μm.

2.Touch control panel,convenient and easy to operate.

3.Low noise, reliable operation, easy cleaning.

4.Rich accessories for option enable various application.

5.Different fineness can be realized by selection of ring sieves with different aperture size.

6. Speed adjustable from 6000-18000rpm.

7. Rotor-ring sieve two stage grinding system ensures reliable grinding result.

8. Rotor diameter 98.5mm and peripheral speed up to 94.2 m/s ensure efficient grinding.

Technical highlights:

1. The specially designed air passage can guarantee that the grinding chamber has constant airflow to cool rotors and samples.

2. There is a double layer wear proof seal ring between the grinding chamber and the driving motor to prevent dust from entering the motor.

3. The electronic lock and the mechanical lock form double protection for operators.

4. The anti-splashing hopper can effectively prevent feedstock blocking and reduce noises.

5. Special adapters can be equipped for large-capacity collections.

6. The motor has the function of overload protection, and it continues torun after restarting due to overload.

Diversified accessories:

3.We offer a special ring sieve with shear function, for most materials, about 80% of the samples can reach the fineness of less than the half aperture size of the sieve used.

Applications

Sample Type: soft,hard,brittle, fibrous
Application Field: engineering / electronics, building materials, agriculture, medicine, chemi- cal/synthetic materials, geology/metallurgy,environment/resource recovery, glass/ceramics.

Typical Samples:
plant material, cement clinker, concrete, compost, coatings and paint, charcoal, hair, catalyst, chemicals, metal, carbon fiber, paper, fiber products, cellulose, seeds, clay minerals, coke, coal, glass, waste electronic products, mineral, ore, limestone,gypsum, quartz, kaoin, bones, metal oxide, iron ore, ceramics, polymers, bentonite/bentonite, pigment, and so on.

Working Principle
When the planetary ball mill starts, the motor drives the common sun wheel to move, while the grinding jars, which are located on the sun wheel, turning around its own axis. The direction of the movement of the sun wheel is opposite to that of the grinding jars in the ration 1:-2.The grinding balls in the grinding jars are subjected to superimposed rotational movement, the so-called Coriolis forces. Under this interaction, the grinding balls release high dynamic energies. The samples are constantly impacted by the grinding balls, and rapid crushed by the friction of the grinding jar's inner wall at the same time.

Speed Ratio Is Customizable
The planetary ball mill BM20 have 2 grinding stations. The parameter can be set according to the sample property freely. Wide kinds and high quality grinding materials are available for choice. Grinding balls of different quantities and sizes can be combined flexibly to meet personalized special crushing and grinding requirements. When the planetary ball mill is in operation, extremely high impact energy are produced between the grind- ing balls and the grinding jars, so it can finish the grinding of the sample in a very short time. The working principle of the planetary ball mill is based on the relative rotation of the sun wheel and the grinding jar. The speed ratio influences the input energy and results of grinding directly. We can customize the speed ratio from 1:1 to 1:-3.5 as customer requirements.
