第一步：挖斗电机和减速机带动挖斗从河道内采掘矿物料，通过升降绞车控制水

The first step: the bucket motor and reducer drive the bucket to extract mineral materials from the river, and use the lifting winch to control the lifting of the underwater boom to extract mineral materials of different depths; use the hull moving winch to control the forward, backward and lateral movement of the hull , Thereby fan-shaped mining of mineral materials in different areas of the river. <br>Step 2: The digging bucket will evenly lift the mineral material in the river channel into the trommel (the trommel is full of stirring teeth, and the skeleton is processed by lathe parts, which is sturdy and durable. The screen is made of wear-resistant high manganese steel. The flushing pipe is used to fully wash the mineral materials. There is also a flushing pipe on the outside to flush the screen strongly to prevent the screen from clogging and achieve a better screening effect. The mineral material first enters the drum of the drum screen and is flushed with high-pressure water Under the action, the stirring teeth fully disperse the mineral material into slurry, and then enter the screening system to clean the mineral material before screening). <br>The third step: the mineral material ≤10mm enters the two chutes for ore beneficiation through the drum screen and the hopper, adjust the chute angle and water flow rate, and use the imported Mitsubishi gold carpet to recover gold. <br>The fourth step: the mineral material> 10mm is directly discharged after being cleaned by the drum screen.

Step 1: Digging motor and reducer drive the digger to extract mineral materials from the river, control the underwater arm lifting by lifting the winch, in order to extract mineral materials of different depths, and control the hull forward, backward and horizontal movement through the hull movement winch, so as to fan the mining of mineral materials in different areas of the river channel.<br> Step 2: Digging pipe will be the river inside the mineral material evenly raised to the drum sieve (roller sieve is covered with stirring teeth, skeleton by the bed parts processing, durable, screen for wear-resistant permanganese steel, roller sieve internal flush pipe, mineral material is fully washed, external also with flush pipe, strong flushing screen, prevent screen blockage, play a better screening effect.) The mineral material first enters the drum sieve, under the rinsing effect of high-pressure water, stirs the teeth to fully disperse the mineral material into the mineral slurry, and then enters the screening system, washes the mineral material clean and then sifts.<br>Step 3: The ore material of 10mm is sieved by the drum into the two chutes to select minerals, adjust the angle of the chute, the water flow rate, and recycle the gold with the imported Mitsubishi gold blanket.<br>Step 4: 10mm of mineral material is sieveed clean by the drum and then discharged directly.

The first step: the bucket motor and reducer drive the bucket to extract mineral materials from the river. The lifting winch controls the lifting of the underwater boom to excavate mineral materials of different depths; the ship moves the winch to control the forward, backward and transverse movement of the hull, so as to fan-shaped mine the mineral materials in different areas of the river channel.<br>The second step: the bucket will evenly lift the mineral materials in the river channel into the drum screen (the inside of the drum screen is full of stirring teeth, and the framework is processed by lathe parts, so it is strong and durable. The screen screen is made of wear-resistant high manganese steel. There is a flushing pipe inside the drum screen to fully wash the mineral materials, and the external flushing pipe is also provided to strongly wash the screen to prevent the screen from blocking, so as to achieve better screening effect. Mineral materials first enter the drum of drum screen. Under the effect of high-pressure water, the stirring teeth fully disperse the mineral materials into pulp, and then enter the screening system to clean the mineral materials before screening).<br>The third step: mineral materials less than or equal to 10 mm are sent to two chutes for beneficiation through drum screen hopper. The angle of chute and water flow velocity are adjusted, and gold is recovered with imported Mitsubishi gold blanket.<br>Step 4: the mineral materials with the diameter of more than 10 mm are directly discharged after being cleaned by the drum screen.<br>
