Disposition for collecting suspended particles to be applied in grain drying machines, where each drying machines comprises a drying tower that generally includes at least one air outlet which lets air with particles in suspension to exit from the dryer machine, each one of said outlets incorporates an aspiration turbine which expels air from the dryer towards the outer atmosphere. The collector particle disposition by each air outlet used in the dryer comprises a tubular structure formed by a primary cyclone and a secondary cyclone. The primary cyclone has an inlet portion connected to the respective dryer air outlet and an outlet portion where an air particle separation zone is defined. The primary cyclone presents a first air outlet, which lets air without particles to flow outside, and a second air outlet, which lets air with particles to flow towards the secondary cyclone. The particles separation zone includes an inner cylinder that defines, between its outer surface and the surrounding inner surface of the primary cyclone, a chamber that lets particles to be conduced towards the secondary cyclone. The derivation chamber is tangentially communicated with an upper portion of said secondary cyclone, which is straight and tubular
