Page 1 of 2 - Ball Mill vs Coffee Grinder - posted in Pyrotechnics: instead of ball milling, can I just use a number of different coffee grinders to separately grind each chemical to a very fine dust, before I mix them by either the diaper method or mesh screens. Those little blade coffee grinders work really well for Potasium Nitrate and Sulfur.
Rod mill VS ball mill-shape and internal structure. The shape design of the rod mill and the ball mill are similar, and both adopt horizontal rotatable cylinders.

involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
Figure 1: Sliding-abrasion action in a Ball Mill. Figure 2: Cascading-impact action in a SAG mill. Rubber and composite mill lining systems. In the past, grinding mills were typically lined with cast metal linings of varying steel or iron alloys, and lining system selection was typically driven by level of wear protection and cost.
The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.
A Ball Mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the Ball Mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 hour and 24 hours. As the Ball Mill rotates, the lead balls will crush the chemicals together, forcing some of the Potassium Nitrate into the pores of ...
SAG vs Ball Mills It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills.
Conventional Ball Mill vs. Attritors High Energy Ball Milling In discussions on high energy ball milling, the more generic term "ball mills" is often used in place of the terms "stirred ball mills" or "Attritors," but the differences between the types of mills are quite distinct.
Disc mills are relatively expensive to run and maintain and they consume much more power than other shredding machines, and are not used where ball mills or hammermills produce the desired results at a lower cost. HAMMER MILL: A hammermill is a machine whose purpose is to shred or crush aggregate material into smaller pieces.
SAG vs Ball Mills It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills.
Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
