The stone cart separates stones from the wheat, which might be the same size, but weight more, c. 1940. Photo by Jordi Cassú. Castelló d'Empúries Flour Mill and Eco-Museum.
It is part of the cleaning section on the first floor. It is made of a slightly tilted table, which moves in a swinging motion. The table has a series of channels with triangular obstacles where the flour is distributed evenly. Through a combination of the movement, tilting and obstacles, the wheat, which weighs less, goes out on one side, while the heavier stones are collected on the other side.
