1.	In core sand preparation, roller mills are suitable for core sand that contains only a single binder called cereal binders.(a) True(b) FalseThe question was posed to me in an interview for job.The doubt is from Core Making Machines topic in section Foundry Mechanizations of Casting-Forming-Welding I
Answer» Correct choice is (a) True The best explanation: In the case of ROLLER mills, the rolling function of the mulling MACHINE along with the turning over movement caused by the ploughs gives a satisfactory and HOMOGENEOUS MIXING of core sand. Roller mills are only suitable for core SANDS that contain cereal binders, whereas the core sand mixer can be suitable for all types of core binders.
