Uniform and homogenous mixture of core sand can be achieved by manual

1.	Uniform and homogenous mixture of core sand can be achieved by manual operation.(a) True(b) FalseThis question was addressed to me in my homework.This intriguing question comes from Core Making Machines in division Foundry Mechanizations of Casting-Forming-Welding I
Answer» Correct option is (b) False Easiest explanation: Preparation of uniform and homogenous MIXTURE of core sand cannot be POSSIBLE manually. So for better and uniform core sand properties using PROPER sand constituents and binders, the core sands are generally blended with the help of roller mills or core sand mixer which uses VERTICAL revolving arm type and horizontal paddle type mechanisms.
