What factors need to be considered in the treatment of machine-made sand-gravel slurry
2021-10-08
The muddy water and sewage in the sand field mainly come from the muddy water produced by the sand washing machine. This muddy water mainly contains a large number of suspended solids of construction materials such as sand and cement. Only by removing these suspended solids, the water quality will become clear. The sewage generated in the production process of machine-made sand has a large amount of water, overall turbidity, and high viscosity. The current common treatment method is to use a sludge dewatering machine after flocculation and sedimentation. The dewatering of stone powder is dedicated to solid-liquid separation to remove solid suspension in the water. The separated clean water can meet the national environmental protection regulations and can also be reused.
1. What is the amount of sand in the mud?
If the solid content of the sand field mud is 30%, and the fine sand in the 30% mud accounts for half or at least 20%, then it is best to first extract the fine sand in the sand field mud (using sand washing recovery Machine to recover tailings), extract this part of the fine sand, but also generate considerable profits. Part of the metal may be recovered from the fine sand, and the fine sand can also be sold directly. After the fine sand is extracted, the remaining mud is almost non-sticky and not easy to settle. Paste-like sludge, these sludge can be dewatered with a machine-made sand and stone powder slurry dewatering machine to achieve the desired effect. Or use sand mud filter, sand making mud filter press, stone powder sand mud dry discharge machine is used to process mud in the stone yard.
2. The content of fine sand in the sand field mud is low
The content of fine sand in the sand field mud is less than 20% of the total concentration. In this case, there is no need to extract the fine sand. With such low content, it is not cost-effective to extract separately. You can directly use a machine-made sand and stone powder slurry dehydrator for dehydration. Treatment, to reach the reuse standard.
3. How to deal with mud effectively?
Sand yard mud filter, sand mud slurry filter press, stone powder sand slurry dry discharge machine, is the equipment used for the treatment of quarry mud, sand washing sludge from sand washing plants, and sandbag soil water washing mud treatment equipment. The common features of this equipment adopt the principle of automatic dewatering and squeezing dehydration, which can quickly squeeze out the water from the mud drawn to the equipment into dry mud. The pressed water is also clean water, which can be recycled or discharged, can be automatically processed, and is easy to operate, Without manual guards. Solve the mud treatment problems and environmental protection problems of the quarry and sand washing plant owners, and escort the stable production of the sand washing plants and quarry owners.
4. Benefits of using stone powder sand mud dry discharge machine
1) The sand-washed yellow mud comes out of the equipment to be dry mud.
2) The treated sludge becomes clean water, which can be recycled for sand washing, without wasting water resources and reducing water costs.
3) The dry mud pressed out by the sand washing sludge treatment equipment cannot be grasped by the hand and can be directly packaged and transported without dripping.
4) The process flow can be designed according to the customer’s site, and the sludge treatment process can be automated.
It is used to process the sand washing yellow mud to realize the separation of mud and water. After the sand washing yellow mud enters the machine, mud cake and clear water come out. The clear water can be used for recycling, which can be discharged or recycled to wash the sand.
