For this purpose, a large number of parameters are provided in the respective tables with the power data. ▪ In most cases, customers make the calculations through us. Together with the offer a data sheet will be created. The data sheet serves for the documentation of all parameters coming from the customer and is often used as a supplement in the documentation of the screening plant. The following parameters are determined by the customer or calculated by PAVO AG: Weight of the oscillating mass − The weight of the screen box with the distribution to the support points at the feed end and the discharge end − The weight of the material at a standstill or with the consideration of the coupling in operation − The influence of the forces through the supplied material flow or the spontaneous loading − Weight of unbalance shafts or unbalance motors Power data − Check the maximum permissible amplitude peak to peak − Check of amplitude peak to peak to the oscillating mass and the working moment of the drive − Calculation of the oscillating machine factor − Check the output rate (if sufficient data is available) Isolation and dynamic force transmission − The insulation efficiency of the selected screen mountings with the existing system parameters − The residual dynamic force transmission at the support points General − If the data are known, recommendations are made about process or environmental influences − Indication of missing or implausible data Offer − If useful, several variants are offered Diagram for the determination of the theoretical conveying speed for free oscillating screening plants 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Vm [m/min] amplitude peak to peak [mm] Vm theo. material speed (direction angle of impact 45°) 2880 1/min 1440 1/min 960 1/min 720 1/min 9.3g 2g Further information ➢ can be found on our website www.pavo.ch/downloads ▪ Technical information about the products from PAVO AG ▪ Storage, Cleaning, Durability, Withdrawal and Disposal ▪ General Terms of Sale and Delivery ▪ Statement to REACH, RoHS, CE marking and ATEX
