Enumerate several embodiment below.
One, regularly (blanking time) and quantitative calculation embodiment:
When if a certain grinding machine grinds the average platform of certain some (refer to change in the regular period several heterogeneity ores) ores treating capacity be one hour 80 tons, the milling medium unit consumption is 1.5 kilograms during average platform, the milling medium total amount consumed is in the time of every: 1.5 kilograms of * are 120 kilograms for 80 tons, if used milling medium substance is 12 kilograms, the number of milling medium consumption is in the time of every: 120 kilograms/12 kilograms is 10, each hour added 10 milling mediums, 60 minutes/10 is 6 minutes, be that a milling medium was added at every interval in 6 minutes, 10 milling mediums of interpolation in a hour.
The formula of blanking time is: blanking time=60 minute/((1.5 kg/ton * 80 tons/60 minutes)/12 kilograms)=6 minutes.
The computing formula of blanking time is: the blanking time=time during platform (minute)/{ (treating capacity (ton) during milling medium unit consumption (kilogram) * platform)/milling medium substance (kilogram) }.
Calculated example 1:60 branch/((1.5 kilograms * 80 tons)/10 kilograms)=5 (minute).
Calculated example 2:60 branch/((1.5 kilograms * 80 tons)/8 kilograms)=4 (minute).
Calculated example 3:60 branch/((1.5 kilograms * 80 tons)/4 kilograms)=2 (minute).
Above-mentioned formula only is to calculate the computing formula of once only replenishing a medium, if once needing to replenish N medium formula can change into: " once replenish N medium the blanking time=time during platform (minute)/{ (treating capacity (ton) during milling medium unit consumption (kilogram) * platform)/(milling medium substance (kilogram) * N) } ", be the computing formula of the blanking time of once replenishing N medium.
Two, speed regulating control embodiment: it is 4 that the material nest on the known material roller is counted fixed value, and the handling capacity fixed value of each material nest is 10 kilograms.
According to calculated example replenish medium be 5 blanking time (minute), motor speed indicating graduation sign is transferred at 250 rev/mins, material roller rotating speed scale marker transfers (correspondence) at 0.05 rev/min, charging room interval scale marker transfers (correspondence) at 5 minutes, per minute charging scale marker transfers (correspondence) at 2 kilograms, and platform fashion material scale marker transfers (correspondence) at 120 kilograms.
If it is 4 that the material nest on the known material roller is counted fixed value, the handling capacity fixed value of each material nest be 10 kilograms constant.
If replenish medium change 4 blanking time into (minute), motor speed indicating graduation sign is transferred at 312.5 rev/mins, material roller rotating speed scale marker transfers (correspondence) at 0.0625 rev/min, charging room interval scale marker transfers (correspondence) at 4 minutes, per minute charging scale marker transfers (correspondence) at 2.5 kilograms, and platform fashion material scale marker transfers (correspondence) at 150 kilograms.
If it is 4 that the material nest on the known material roller is counted fixed value, the handling capacity fixed value of each material nest be 10 kilograms constant.
If replenish medium change 6 blanking time into (minute), motor speed indicating graduation sign is transferred at 208.33 rev/mins, material roller rotating speed scale marker transfers (correspondence) at 0.0417 rev/min, charging room interval scale marker transfers (correspondence) at 6 minutes, per minute charging scale marker transfers (correspondence) at 1.6667 kilograms, and platform fashion material scale marker transfers (correspondence) at double centner.
