Abstract: A cooling arrangement and system are provided for use in a process of producing brittle particles, and comprising: a first chamber comprising an air ingress for receiving air conveyed to the first chamber, and an air egress for introducing air leaving the first chamber to a second chamber; a second chamber comprising an air ingress for receiving air egressing the first chamber, and an air egress for discharging air leaving the second chamber; a solid particles feed ingress means; an enclosure formed by a space confined between the walls of the first and second chambers, through which solid particles fed via the solid particles feed ingress means fall downwardly towards the bottom part of the cooling arrangement; and a solid particles egress means. According to an embodiment, the cooling arrangement further comprises a shaft that is operative to enable movement of the first chamber.
