Laboratory Ball Mill. Laboratory Ball Mill is primarily designed for grinding pigments. The material is ground at a specific speed by using a specific quantity of grinding media (steel balls) for a specific period. The equipment is used for making the ground cement samples in the laboratory.

 · Planetary ball mills are the most commonly used ball mills in laboratories for preparing samples ranging from soft to hard to brittle and fibrous materials. The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating "sun" disk that rotate in the opposite direction around the disk centre.

The field of invention is related to a method of producing nanoparticles of less than 100 nm using a stirred media mill and a novel stirred media mill for producing the nanoparticles. The dead zones present in the stirred media mill, are the main cause of long time grinding and wide size distribution of product and is rectified in our design by optimum design of stirrer which will transfer the ...

The HCPN Immersion Mill is the cutting edge in nanoparticle production. This revolutionary machine makes the science of nanoparticle manipulation user friendly, clearing the path to new product development. Hockmeyer's patented containment wall ensures the retention of very small media.
