The construction and grinding operating principle of meat grinders sh ould have minimal effect to meat losses. This paper presents the engineering calculation of the cutting process of meat grinder. The experimental grinder consists of a frame, screw, gearbox, electric motor, V-belt transmission, casing, lock and hopper.

It's quite easy to convert kW to amps and amps to kW in a simple 1-phase DC circuit (compared to a 3-phase power calculation). That requires only the basic Ohm's law; you can simply use our kW to amps calculator here for conversion.. In a 3-phase AC circuit (usually a 3-phase motor), converting amps to kW and kW to amps is not all that easy.

Induction motors are made from fractional horsepower ratings like 1/3 hp to thousands of horsepower. For a decent 2" x 72" belt grinder, we're looking for ideally 1 to 3 horsepower, with a preference for 1.5 to 3 horsepower. The motor needs to have enough power to perform efficient knife grinding and general metal shaping tasks.

grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the

0 amps = 0 HP (or 0 KW) FLA = rated HP (or rated KW) Like Reply CSA Jun 5, 2013 #4 Kam, For a three-phase AC motor the formula for power consumed by the motor is: Watts = V * I * 3^0.5 * pf. (The 3^0.5 is the only way I can express "the square root of three" on this forum, which is approximately 1.732.)

Calculate 3 Phase Apparent Power(kVA) horsepower (hp) efficiency (%) Power Factor- PF - three phase motors(0 - 1) RLA - "Running Load Amps"- current drawn during normal operation of electric motor. FLA - "Full Load Amps"- amount of current drawn when full …

P(kW) = √3 × PF × I(A) × VL-L (V) / 1000 Calculation with line to neutral voltage The power P in kilowatts (kW) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V) divided by 1000: P(kW) = 3 × PF × I(A) × VL-N (V) / 1000 Typical power factor values
