THE SEPARATORS OF BURMEISTER AND WAIN.

can be unreservedly recommended. At present four other separators 

 are used or made, the bowl-separators (A) and (B) for machine use, 

 the separators (X 1), (A), and (X 2) for hand use (figs. 40 and 41). 

 The separators of Burmeister & Wain are characterized by their 

 elegant construction and their smoothness of working. They allow 

 the quantity of cream to be regulated during the revolution of the 

 drum, und alone among separa- 

 tors offer the extremely and uni- 

 versally valuable advantage, 

 that it is possible, if desired, to 

 pump up the cream and the 

 skim -milk several metres in the 

 ascending tubes. Cream and 

 skim -milk gush out at the end 

 of the exit tubes more strongly 

 than is the case with other 

 separators. Owing partly to 

 their fine construction, they 

 require to be carefully and 

 intelligently handled. 



They are provided with a self- 

 acting security arrangement, 

 which prevents an increase of 

 the speed above the regulated 

 degree. It may be added that 

 these separators may be used 

 in the simplest manner for pre- 

 paring emulsions of oil and 

 skiin-milk for calf feeding. 



The following are the dimen- 

 sions of a number of separators 

 made by Burmeister & Wain:
