The size of the WPEX80-135,WPEX80-147,WPEX100-155,WPEX120-175,WPEX135-200 motor reducer needs to be determined based on factors such as the volume of the mixing drum, the density of the mixed material, and the mixing speed. Here is a simple calculation method:
Calculate the volume of the mixing drum. The volume of a conical mixing drum can be calculated using the following formula: Volume=1/3 x π x (diameter/2) ² Height. Based on the diameter of 2 meters and the shape of the conical mixing bucket given in the question, the height of the conical mixing bucket can be calculated to be 2 meters, resulting in a volume of 1/3 × π × (2/2) ² 2=2.09 cubic meters.
Calculate the density of the mixture. Based on the weight of 7 tons and volume of 2.09 cubic meters given in the question, the density of the mixed material can be calculated as 7/2.09=3.34 tons/cubic meter.
Determine the stirring speed. Determine the stirring speed according to actual needs, usually expressed in terms of speed. Assuming a speed of 30 revolutions per minute.
Calculate the required torque. Torque is an important parameter of the motor reducer, which needs to be determined based on factors such as the volume of the mixing drum, the density of the mixed material, and the mixing speed. Generally, the following formula can be used to calculate: torque=power/(2 x π x speed/60). Assuming the selected motor has a power of 10 horsepower and a speed of 30 revolutions per minute, the required torque can be calculated to be 10 x 735.5/(2 x π x 30/60)=9425.2 Newton meters.
Choose the appropriate motor reducer. Select the appropriate motor reducer based on the required torque and speed. It should be noted that the rated torque of the motor reducer should be greater than the required torque, and the speed should also meet the requirements.
The above is a simple calculation method. In actual selection of the size of the motor reducer, other factors need to be considered, such as usage environment, working time, etc. It is recommended to consult professionals or suppliers before making a choice.
