Basic knowledge and advantages of roll crusher Roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks in mine selection‚ chemicals‚ cement and building materials industrial production. Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining

Trimyristin is an ester with the chemical formula C45H86O6 that can be isolated from the common spice nutmeg. The seed of the evergreen trees in the genus Myristica Fragrans is what nutmeg is obtained from. Trimyristin is the triglyceride of myristic acid also known as saturated fat (3). The phase of trimyristin is solid and is only found soluble in dichloromethane‚ chloroform‚ ether‚ benzene‚ and ethanol (1). Only twenty to twenty-five percent of trimyristin makes up the mass of nutmeg and it
