Embodiment 1
[0067] The water is sent into the mixing container 8, the hydraulic filling pump 9 and the delivery pipeline 11 sequentially through the water supply device 6, the water is tested for 3 minutes, and the filling pipeline is lubricated; Feed silo 4; send excavated gravel with a particle size of 16 to 20 mm into the second feeding silo 5 through the second belt conveyor 2; send cement into the mixer 7 through the feeding mechanism 3, and stir to obtain a weight concentration of 65% water in the stirring container 8 through the water supply device 6, when the water in the stirring container 8 reaches the material level of 1 / 3 of the stirring container, start the stirring container 8, and then put the cement slurry in the mixer 7, the first feed The ultra-fine full tailings in the silo 4 and the excavated gravel in the second feed bin 5 are successively and continuously sent into the mixing container 8, and the weight ratio of the ultrafine full tailings sent into the mixing contain...
Embodiment 2
[0073]Start the water supply device 6, and the water supply device 6 sends water into the stirring container 8, the hydraulic filling pump 9 and the delivery pipeline 11 in sequence, test the water for 5 minutes, and lubricate the filling pipeline; send the ultrafine tailings through the first belt conveyor 1 into the first feeding bin 4; through the second belt conveyor 2, the excavated gravel with a particle size of 16-20mm is sent into the second feeding bin 5; through the feeding mechanism 3, the cement is sent into the mixer 7, and stirred to obtain the weight Concentration is the cement slurry of 7.2%; Inject water in the mixing container 8 through the water supply device 6, after the water in the stirring container 8 reaches the material level of 1 / 3 of the mixing container, then the cement slurry in the mixer 7, the first feed The ultrafine tailings in the silo 4 and the excavated gravel in the second feed bin 5 are successively and continuously sent into the mixing con...
Embodiment 3
[0075] Start the water supply device 6, and the water supply device 6 sends water into the stirring container 8, the hydraulic filling pump 9 and the delivery pipeline 11 in sequence, test the water for 4 minutes, and lubricate the filling pipeline; send the ultrafine tailings through the first belt conveyor 1 into the first feeding bin 4; through the second belt conveyor 2, the excavated gravel with a particle size of 16-20mm is sent into the second feeding bin 5; through the feeding mechanism 3, the cement is sent into the mixer 7, and stirred to obtain the weight Concentration is the cement slurry of 68.5%; Inject water into the stirring container 8 through the water supply device 6, after the water in the stirring container 8 reaches the material level of 1 / 2 of the stirring container, then put the cement slurry in the mixer 7, the first feed The ultra-fine tailings in the silo 4 and the excavated gravel in the second feed bin 5 are continuously sent into the mixing contain...
