Meadows 8 inch Commercial Stone Burr Grain Mill - pleasanthillgrain

A 75% duty cycle means that out of each hour, the mill will grind for 45 minutes, then requires a 15 minute cool-down. The 2HP -220V model has a 100% duty cycle so it can operate continuously. The 2HP model is sold with an On/Off switch, power cord and Nema 6-20p plug and a Nema 6-20r receptacle.

Guide to Compressed Air Piping Systems | Quincy Compressor

Turbulence leads to a pressure drop, and it will only get worse if the compressor's output is turned up. Avoid these 90-degree elbow corners as much as possible — otherwise, they'll lead to turbulence, decreasing the pressure delivery. A straight path in airflow is the most efficient.

Milling about | Article about milling about by The Free Dictionary

Air-pressure mills are used for very fine milling (to a grain size of 0.001-0.05 mm). Ground material is introduced into ejectors facing one another. Compressed air under a pressure of 0.4—0.8 meganewton per sq m (40-80 kilograms-force per sq cm), super-heated steam, or hot gaseous combustion products are introduced into the ejectors.
