Sun flower cracker if connected with variable speed drive can be used as sunflower decorticator. Sunflower cracker works on centrifugal force. Rotor revolves at about 2800 RPM. Sunflower is dashed against outer wall and so it breaks in to pieces. But at particular speed, it simply breaks the husk and not the seeds.

Mill drills are an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine's table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit. The JMD Milling Drilling ...
Key considerations Burr vs. impact mills. Grain mills all employ some mechanism to grind, crush, or shred the grain. You can choose from three main mechanism types: stone burrs, metal burrs, and impact mills. Traditional milling mechanisms employ burr grinders, in which two plates grind the grain.

In each of the three drive system components, variable speed control is possible. Variable speed control can be accomplished, for example, using a frequency converter as the energy control component, a two speed motor as the motor component and gears as the transmission component. As mentioned earlier, most machines are driven by an electric motor.
Two of the cranes are rated at 16t and have been retrofitted with AC variable speed drives, while the two larger 25t cranes are using DC drives. The AC-motors for the hoist and close movement of the grab, as well as the motors for the luffing and slewing movement, are all equipped with AC drives. A notable feature of this installation is ...
