A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition size reduction is done by.
Except for very small batches, ball milling is the best way for the amateur fireworker to reduce particle size in their chemicals. With small batches of individual chemicals, some folks use electric coffee mills to grind the chemicals into fine powder.
Powerful black powder can be made with mill runs of between 2 and 4 hours. Use long drop cords. Unplug the cords at the electrical source, not at the ball mill, when you want to stop the mill. Run your mill remotely, outdoors, at least 150 feet away from people and inhabited buildings.

Laboratory Size Reduction Mill For Stone Ultrafine powder grinding for lab use Widely used for mineral,metal,chemical,ceramic,medical industry Can grind most material down to 2 5 mircon. Send Inquiry.
Cone milling is one of the most common methods of milling in the pharmaceutical, food, chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules Generally used for reducing material to a particle size as low as 180 m (80 mesh) a cone mill produces less dust and heat than alternative forms of milling.
3.6.1.1 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs nanosize using different sized balls. The working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.
Our particle size reduction and sizing methods are used in a number of industries. We’re experts in attrition milling and ball milling, and have experience in mechanical alloying for ODS (oxide dispersion strengthened) applications. We also have PLC controlled attrition mills.
