Ball milling in organic synthesis: solutions and challenges

Ball milling in organic synthesis: solutions and challenges

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

Ball mill trunnion

Ball mill trunnion

A ball mill trunnion is a cylindrical protrusion used as a mounting and/or pivoting point for the bearing and seals of the mill's rotating drum. It is designed to support and rotate the drum along with the material inside, while providing a secure and durable connection between the drum and the rest of the mill. Trunnions are typically made of ...

Investigation of StressStrain State of Ball Mill Trunnion

Investigation of StressStrain State of Ball Mill Trunnion

The equations describing the movement of the trunnion points of the ball mill are derived. The stressstrain state of the trunnion of the ball mill was determined depending on the temperature of the inner and outer surfaces of the trunnion. Deformations and stresses arising on the surface of a pin are investigated by numerical methods.
