What are Reduction Gears | Introduction, Types and Reduction Ratio …
What is a Gearhead. Reduction gearheads use the concept of gear reduction which implies that the gears reduce the speed of the machine but increase its torque. They are usually made of steel, hardened metal, nylon, plastic, or rubber gear. The usage of sintered gears is also increasing to decrease the expense of gear production.

Tips to maximize crushing efficiency
Efficiency can be defined by the ratio of a machine's work to the energy supplied to the machine. To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products – up to 40 mm in size.

How to Calculate Speed Ratio
When a machine has two gears of different sizes, the smaller gear turns faster than the larger gear. When the first gear (the driver or input gear) turns, the second gear (the driven or ouput gear) turns in response. The difference between the speeds of the two gears is called the speed ratio or gear ratio.

How to select gear ratio for a gear reducer?
To calculate the required gear ratio when torque multiplication is needed, use the equation: G = T LOAD / [ T MOTOR x e GEARS] where G is the gear ratio, T is torque and e is efficiency. Another function of gear reducers is to reduce the reflected load inertia to the motor by a factor of the square of the gear ratio.

How to Use Pulleys for Speed Reduction
Basically the speed of the output pulley becomes the input speed for the next stage, and you can find the multi-pulley drive. If the input speed is 75 rpm, the output speed equals 75 rpm divided by 3 or 25 rpm. In turn, one can find the output torque from the driver pulley to the driven pulley by multiplying the input torque by the velocity ratio.
