Even if the air temperature is mild, the surface temperature of the metal can get quite hot. Air temperatures in a ball pythons enclosure should never exceed 95#176;F (35#176;C)! Temperatures can typically drop to room temperature at night without negative effects, and may actually be more beneficial for the snakes longterm health.

#0183;#32;But I think it is a leap to say that at of the rated power the body temperature will rise 85degC. But with that said, that is the question. At a given ambient temperature for a rated power dissipation, what is the expected rise in body temperature. TO220 transistors give this information under thermal characteristics in the line item degC/W.
Vishay uses MILPRF27 to determine temperature rise due to applied DC current. An excerpt from MILPRF27, specifically Section Temperature rise, is copied below. MILPRF27 calls for the device under test (DUT) to be soldered onto copper plates, with the assembly then being put inside a box with prescribed dimensions and no airflow.
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber.

Table 1 shows the temperature rise limits for NEMA medium electric motors based on a maximum ambient temperature of 40 C. In the most common speed ratings, the NEMA designation of medium motors includes ratings of 1/2500 hp for 2 and 4pole machines, and up to 350 hp for 6pole machines.

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling balls in the bowl.
