Vibrating Efficiency Calculations

For the efficient use of  number of conditions need to be met, starting from the selection of a suitable . Many factors related to the material, such as type, humidity and size distribution should be considered in the selection of the right  These factors are presented in Table 1. Choosing the correct  type and the right dimension is something that requires expertise. MEKA’s expert engineers will boost your profitability by choosing a  that is right for you.

Another important factor affecting  efficiency is the choice of the baffle, which can be made of such materials as wire and polyurethane. The baffle should be resistant to vibration, should have sufficient open space and should be resistant to wear. The relationship between the type of and the  baffle is shown in Table 2.

The efficient operation of a s related closely to how the s fed. The belt that feeds the  should provide feeding in parallel with the flow direction of the material, and in a manner that brings the materials to the center of the loading vessel. Picture 1 shows proper feeding and improper feeding.

Picture 1. On the left is the proper way of feeding the , while on the right is the improper way of feeding the .

Another important factor in efficient  is the layer height (or bed). The layer height refers to the height formed by the layer on the wire surface at the point at which the material is loaded. The ideal height is four times the aperture.

The capacity and efficiency of  are usually inversely proportional. The usual target is a  efficiency of 95%. An efficiency of 99% will equate to a significant loss of capacity.

Efficiency is the ratio of undersize material in the feed that actually passes from the  media to the undersize material that should pass from the  media. This ratio is desired to be 100%, however this is not possible due to the factors affecting the process.

However, acceptable efficiency ranges have been determined by producers and quarry managers to ensure an optimum  process. According to the determined ranges,efficiency should be in the range of 90%-95% with respect to the above formula.

Feed rate is the main parameter dictating efficiency. If the flow rate is below the capacity of the media, the  runs idle so no s carried out. On the other hand, if the flow rate is above the  capacity of the media,  runs under the overflow rate, and in this case no is made due to the high material depth on the media. Accordingly,  selection has to be made with due attention paid to the flowrate to obtain maximum  efficiency.

Efficiency is affected by the factors listed below:

 
• Wear, abrasion and tearing in then baffle.
 
• Feeding too much or too little material onto
 
• Large changes in grade.
 
• Humidity level of the  material.
 
• Efficiency of the machine used prior to.
