Abstract

PURPOSE: To prevent the disturved mixing at the start of quarry where the materials from many material tanks are mixed through measuring conveyor on collective conveyor, by controlling the drive of each measuring conveyor with time difference while considering the residual material on measuring conveyor.
CONSTITUTION: At the start of operation, the weight of residual material on each measuring conveyor 104 are detected. The regulating time is calculated for each material tank on the basis of said detected weight, then quarry conveyor 101 and measuring conveyor 104 for each material tank are started earier by said regulating time from the time point when the mix ratio changing point on collective conveyor 100 or the leading end of material passes directly below each material tank. Consequently the material from each material tank is fallen on collective conveyor thus the disturved mixing at the start is prevented.
