The reason your ball mill exploded is pretty simple; potassium chlorate and aluminium should not be ball milled together. If your going to say; "I done it many times before without a problem." just consider that your were lucky those times before. Potassium chlorate shouldn't be ball milled with any fuels, metals in particular.
MINDEN, La.—Nearly two years ago, an errant spark inside a mill caused an explosion so big it destroyed all the building's equipment and blew a corrugated fiberglass wall 100 feet.
Dropped charges experienced in large ball mills can be heard and felt hundreds of meters away and can be confused with an explosion or earthquake onsite, such is the force of the impact.

To do so would be to court disaster. The Ball Mill Lloyd Sponenburgh, in his Ball Milling Theory and Practice for the Amateur Pyrotechnician, tells us his explorations into ball milling began when he was faced with having to do all that grinding with a mortar and pestle to achieve small particle size and intimately mix his chemicals.
The chamber,which is constructed from PVC, has a fail safe to prevent an explosion. A hole has been drilled in the end cap and plugged with hot glue. In the event the milling material starts to ...

Bag Filter Maintenance Notes. Bags in a bag filter. Before maintaining or repairing the bag filter, its power supply and air source must be cut off, and the airbag should be under normal pressure. During the maintenance and repair of the bag filter, the dust inside shall be cleaned repeatedly to ensure that there is no dust inside.
You can't efficiently separate chems below 300400 mesh particles with screensthat''s 3744 microns. A mediumthick human hair is 100 microns in diameter. 5 microns is 2500 mesh. The finest mesh screen I've ever seen sold is 625 (20 microns), and a very delicate 12"x12" piece cost about US 1600.
The Washburn Mill explosion in 1881 was celebrated, but it seems to have been a far from infrequent occurrence; writing in Scientific American, we hear of a malt dust explosion: On the 4th of July, 1880, a common lucifer match' among the malt was ignited in the malt mill, in which are two steel grinders, which make about 150 revolutions a minute.
The violence and speed of the explosion are linked to size and composition of the particles. ... The stirred ball mill (SBM) is a custommade prototype (IATE, INRAE, France) that consists of a 2 Lcapacity grinding chamber in which a rotor operating at 330 rpm drives the milling media ( kg of 6mmdiameter steel beads) mixed with the powder ...
