The invention relates to a test arrangement for testing breakage and mechanical properties of rock particles. Test arrangement comprises a support (1, 2) and two counter-rotatable crushing rolls (3, 3′) supported on the support (1, 2) and a drive arrangement (M1, M2) for rotating the crushing rolls (3, 3′). Crushing rolls (3, 3) are facing each other and defining therebetween an input gap (G) for the rock particles, said rolls being arranged to crush rock particles (RP) to smaller daughter particles (DP). Test arrangement comprises a force measurement arrangement (7, 7) for determining the compressive strength of rock particles (RP). Force measurement arrangement (7, 7′) being coupled to a processor (PR) comprised by the test arrangement. The processor (PR) being arranged to calculate the breakage force applied to each rock particle (RP) over time. The test arrangement (TA) further comprises an energy measurement arrangement (5, 5′) for measuring information relating to energy applied to each rock particle (RP), said energy measurement arrangement (5, 5′) being coupled to said processor (PR), said processor (PR) being arranged to calculate energy applied to each rock particle (PR).

A crushing machine for a vegetable food product frozen in blocks, or in IQF form, the machine having a box-like body defining a crushing chamber. The box-like body has an inlet port through which the frozen food product is put in the crushing chamber, and an outlet port through which a frozen crushed product is discharged from the crushing chamber. In the crushing chamber a crushing unit is mounted, having a plurality of crushing rollers, each of which is arranged to rotate about a rotation axis and has, peripherally, teeth arranged to cut the frozen product into blocks, or IQF form, for splitting it into the above described fragments of predetermined size. The rotation axes of the crushing rollers are parallel to each other. The outlet port is associated with a distribution valve arranged to adjust the amount of crushed product discharged from the machine through the outlet port.

A roller press capable of applying an electric field comprises a base, a frame (12), press rollers, an inter-roller distance adjustment device (11), a speed adjustment device (122), a voltage application device, a feed deflector (19), and a discharge device. A surface of the press roller is made of an electrically-conductive material, and an electric field is created when a voltage is applied to the press roller. In the roller press, an alternating or direct current electric field is applied between the press rollers to create an electrochemical action, such that particles or a solution in a system is induced to undergo a physical or chemical change, thereby enhancing interaction therebetween, and accordingly increasing grinding and dispersion efficiency of a solid-liquid dispersion system.
