Crushing Plant TPH Calculator
Crushing plant TPH (tonnes per hour) depends on feed size, closed-side setting (CSS), material density, crusher type and motor power. This free calculator estimates jaw, cone and VSI output using standard industry formulas — useful for quarry design, RMC planning and DPR preparation.
Estimate your plant capacity
Disclaimer: Results are approximate based on industry-standard formulas (Taggart for jaw, manufacturer throughput curves for cone/VSI) and assume dry feed at specified density. Actual plant output varies with feed moisture, gradation, chamber wear and operator practice. For a detailed plant design and guaranteed capacity, request a free consultation.
How we calculate crushing plant TPH
Each crusher type uses a different engineering formula:
Jaw crusher (Taggart's formula)
TPH ≈ 0.6 × W × CSS × ρ — where W is feed opening width (m), CSS is closed-side setting (m) and ρ is material bulk density (t/m³). The 0.6 coefficient accounts for stroke, nip angle and typical operator loading.
Cone crusher
Cone crusher capacity scales roughly with CSS × eccentric throw × chamber profile. Manufacturer curves give multipliers of 1.4× the equivalent jaw output at the same CSS, due to higher reduction ratio and continuous crushing action.
VSI (Vertical Shaft Impactor)
VSI capacity is driven by rotor tip speed and feed rate, and is typically calculated from motor kW ÷ specific energy (kWh/t). We use 0.85× the jaw baseline at small CSS (sand-making), reflecting higher fines generation and lower throughput per unit feed opening.
