Crusher (cone/jaw) simulation

feed solid -> crushed product (Whiten classification + breakage)

Governing equations

The exact equations the solver works for a crusher (cone/jaw) — the same math shown in the app's "Theory" panel, not a black box.

$C(d)$

classification function — the fraction of size d retained in the chamber and broken

$K_1$

size below which every particle passes (≈ closed-side setting) [m]

$K_2$

size above which every particle is broken (≈ open-side setting) [m]

$K_3$

shape of the classification between K1 and K2

$B$

breakage matrix — where the fragments of each size class land

$f, p$

feed and product mass fractions by size class

Parameters

closed_side_setting_m [m, required — particles below it pass unbroken] and open_side_setting_m [m, required, > CSS — particles above it are always broken] (or k1_m and k2_m explicitly); optional k3 [classification shape, default 2.3], breakage_phi/breakage_gamma/breakage_beta [Austin breakage; omitted = Broadbent-Callcott], bond_work_index [kWh/t, default 12], molar_mass [kg/mol, default 0.1]
