The raw materials are crushed and fed in the correct proportions into a grinding mill, where they are dried and reduced in size to a fine powder. the dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement.
The special property that has been claimed for mechanically extracted linseed meal may be questioned. raw linseed oil is sometimes used as a laxative with farm animals, and many statements have appeared to the effect that one of the beneficial effects of linseed meal can be traced to the 8 or 9 percent of oil in the product.
The wet process gradually developed, initially in more remote wet raw material regions such as the marl belt of central michigan. later, the wet process came to be used in pennsylvania mainly because of the ease of wet blending, but the majority of kilns continued to use the dry process throughout the twentieth century.
