Mini Vibrating Ball Mill

Laboratory sample grinder/swing grinder GJ-3 is also known as laboratory sealed sampler, sealed test grinder, sealed timing grinder, sealed grinder. Mainly used for milling of raw materials for laboratory testing. Vibrating sampling crushers are widely used in coal, coking, non-ferrous metal smelting, mining and other industries. For example, coal, coke, coal gangue, various ores and other fields.

The working mode of vibrating sample grinder: vibration grinding type. In the bowl, the material is placed in the bowl, and the crushing ring and hammer are located in the bowl. The material is crushed and ground by the high-speed rotating crushing ring and hammer within 2-6 minutes, and can be quickly ground into 80-200 mesh (0.175-0.075mm) micron powder samples, which can be directly used for testing.

Bowls include ordinary steel bowls, high manganese steel bowls, wear-resistant alloy steel bowls, chromium steel bowls, tungsten carbide bowls, etc. Bowl selection usually depends on the hardness of the material.

Working Principle:

Place materials in an airtight material bowl. There is a breaker hammer and a crushing ring inside the bowl. The motor drives the eccentric hammer to rotate at high speed. The material is made into powder through vibration, impact and friction.

This powerful ring disc grinder grinds tough, brittle samples in minutes. It has a soundproof housing and can accommodate samples weighing up to 300 grams.

Typical Samples:

Cements, Soils, Ceramics, Slag, Rocks, Minerals, Ores,Pharmaceuticals, Sulfur Pellets, Dried Plant Material and slurry samples.

Features:

Swing the disc-shaped grinding container with discs and rings in a tight, high-speed circular motion to quickly crush the sample.

The soundproof housing reduces noise levels and features an easy-to-use enclosed cam clamp.

The membrane control panel features a 10-minute electronic timer that counts down the remaining time. The "pause" function allows grinding cycles to be interrupted.

Equipped with safety interlock system and capped gas bottles to protect the operator.

The soundproof steel cabinet features a cooling fan to prevent the motor from overheating, and lockable casters allow the grinder to be moved around the lab and then secured in place.
