SCFM refers to “standard cubic feet per minute” or the given flow rate of air at standard room temperature and pressure. Standard air flow is the baseline required flow; depending on your operating conditions (i.e. differing pressure and temperature) this tool allows you to convert the required SCFM, to the actual flow or ACFM that you will read from your instruments.
Otherwise known as peripheral velocity, this calculator determines the velocity of the impact surface of a hammer at the outer edge of a rotor disk. Tip speed is important because the hammer velocity directly affects how much force is applied to particles being milled. Faster tip speeds general produce smaller particles and can increase material throughput.
Used to calculate the amount of air that will pass through the nozzle(s) of a jet mill in SCFM for compressor sizing. Calculating require SCFM for a jet mill is critical to performance. With insufficient air flow, the jet mill cannot achieve optimal results and conversely too much air flow is wasteful and costly to maintain.
A double flap valve is a simple air-lock, the two valves open and close at alternating intervals allowing material to first fill the spool, seal the process area, and then open the other valve to evacuate material out of the bottom. This calculator helps to determine the spool length required for a double flap valve setup given the flap valve sizes and required mass flow rate.
