The crushers, grinders, mills and pulverizers listed in this section have been carefully selected to 

 meet every requirement of the experimental and testing laboratory. They are all American made and 

 have been" in use for enough years under varied conditions to insure their serviceability and durability. 

 In describing them, the attempt has been made in every case to state the particular uses for which they 

 are best adapted, based on the experience of our trade. 



We wish to direct especial attention to the Brann line of crushers, grinders and pulverizers, of 

 which a complete line is carried in stock for immediate delivery.
