Lab Sample Pulverizer

Lab sample pulverizer is a fast, no-loss fine grinding mill

Qingdao Decent Group lab sample pulverizer is also called the laboratory ring mill or laboratory disc mill. It is one of the key pieces of equipment in the sample preparation process. Efficient and accurate experimental results depend on high-quality sample grinding. Our single-bowl and multi-bowl series ring and puck pulverizers are specially designed and manufactured for this purpose.

In the sample preparation process, a Jaw crusher or hammer crusher is used to roughly crush the sample. Then, the sample smaller than 25mm is finely size reduction with a pulverizing disk machine. The grinding time is generally 1-3 minutes. The particle size of the pulverized material can generally reach 120-200 mesh to meet the testing requirements of the laboratory.

The working principle of the pulverize: The motor drives the rotating shaft to rotate with high speed, which generates exciting vibration. Due to centrifugal force, the bowl puck and ring hit, squeeze, and grind the sample to achieve the purpose of crushing.

Advantages of Lab Sample Pulverizer

More Power & Lifetime: The vibratory head is driven by a universal shaft. It is powered by vee belts from a standard, stationary (nonvibrating) 1.5kW electric motor. This drive arrangement delivers more power to the grinding bowls and optimizes motor life. Because it is not exposed to direct vibration as traditional integral vibratory motor-driven.

Various Capacity & Excellent Efficiency: Our multiple grinding bowls pulverizer series also differs from traditional grinding mills. Because it can install one to four grinding bowls with different capacities. And it can reach a maximum total of 1600 grams of samples.

Meanwhile, the multiple grinding bowls design enables testing to proceed with a maximum of four different materials at the same time. It provides excellent efficiency at any time. You can choose the number of grinding bowls from one to four according to your actual need.

Wide Use & Perfect Grinding Effect: Our sample pulverizer is used for ores, minerals, ferroalloys, ceramics, soils, aggregates, and chemicals. Typically, samples can be ground to 95% minus 75-50 microns within 3 minutes depending upon their mass and physical characteristics.

High Output & Low Maintenance: Our pulverizer machine is well-suitable to high volume mineral laboratories. They regularly prepare large samples. And it is also suitable for those remote laboratories. These laboratories do not often do special maintenance services for the integral vibratory motor-driven.

Trouble-free Bowl Clamping Design: The manual mechanical bow clamping adopts a unique quick, easy, and no-loose design. It offers trouble-free operation to the operator during the sample preparation process. No matter where the laboratory is. Whether the laboratory is equipped with a pneumatic system.

Product Video

The above video shows the grinding process of our multiple bowls laboratory pulverizing mill. Please kindly note the video is taken in special condition. Normally the laboratory ring mill will stop immediately when the lid is open during operation, or the laboratory ring mill can never be started when the lid is in open condition. This provides full and necessary protection to the operator during the whole sample preparation process of grinding samples with our rock pulverizer equipment.
