General Crushing Practice. 



The crushing and grinding practice in cement-making is so important 

 a part of the manufacture, and so closely connected with the financial 

 success or failure of the plant, that it requires special consideration, 

 both as to general methods and in regard to the special types of machinery 

 employed. In the present section certain features will be discussed 

 which are common to both the wet and dry methods of preparation, 

 while the following chapter will be devoted to a description of the 

 various standard types of crushing and grinding machinery.
