Planetary Ball Mill
Planetary Ball Mill
A Planetary Ball Mill consists of at least one grinding Vessel witch is arranged eccentrically on a sun Wheel / Rotating table.
When the sun wheel rotates about its axis, the vessel follows planetary motion i.e. it rotates about it’s own axis as well as about the axis of sun wheel.
The direction of rotation of vessel is opposite to that of the sun wheel, this imparts very high energy to the balls to collide with one another during high speed movements causing very fast grinding and mixing of material(s) in the vessels to a very high fineness up to 1 Micron depending upon the physical characteristics of material, number and size of balls, time and speed selection.
Technical Specification
| 1 | Type of Ball Mill | Planetary |
| 2 | Purpose / Capacity | The Planetary type ball mill is suitable for grinding substances including weakened fibers into powder form in both dry and wet conditions. It consists of 4 Jars of 150 ml capacity. |
| 3 | Brief Description | The Planetary Ball Mill shall be consisting of four Grinding Vessel which are arranged eccentrically on a sun Disc. When the Sun disc rotates about its axis, the vessel follows planetary motion about the center of sun disc, the direction of rotation of vessel is opposite to that of the sun wheel, this imparts very high energy to the balls to collide with one another during high speed moments causing very fast grinding and mixing of material(s) in the vessels to a very high fineness up to 01 Micron depending on the Physical Characteristics of material, number & Size of balls and the time and speed selection. |
| 4 | Maximum Input Size | Few microns to 5 mm |
| 5 | Final fineness | 0.5 micron |
| 6 | No. of Bowl Set / Jar | Four |
| 7 | Bowl Set / Jar Capacity | 150 ml |
| 8 | Bowl Set / Jar & Lid Material | Hardened Steel |
| 9 | Ball Material | Hardened Steel |
| 10 | Ball Diameter | 5mm, 10mm, 15 mm and 20 mm (user to specify) |
| 11 | No. of Balls per Jar | 5mm - 10 nos., 10mm - 5 nos., 15 mm - 4 nos., 20 mm - 3 nos. (user to specify) |
| 12 | R.P.M. of Table | Variable 150 - 500 |
| 13 | Variability Control | Microprocessor controlled , continuous |
| 14 | Table Speed Indicator | Digital |
| 15 | Parameter's Display | Digital, Touch screen |
| 16 | Time Range | 0-999 min |
| 17 | Forward & Reverse Selection | Yes |
| 18 | Motor & Drive | Standard Make-2HP, AC-3 Phase 415 V, 1415 r.p.m.; with Microprocesor based VFD. |
