What are the advantages and disadvantages of dry and wet sand and how to choose
In the sand making process, dry sand and wet sand is relative, from the word alone, we can probably guess the main difference between the two is the amount of water used in the sand making process, the actual embodiment of the equipment is to clean the sand and gravel in the finished product of the mud powder is the use of powder selector, or sand washing machine. What are the pros and cons of dry and wet sand making? How to choose more practical?
A. What are the advantages and disadvantages of dry and wet sand?
1. Dry sand process
Raw material → vibrating feeder (feeding) → jaw crusher (coarse crushing) → cone crusher/impact crusher (medium and fine crushing) → vibrating screen (screening large aggregate) → sand making machine (sand shaping) → vibrating screen (screening small aggregate) → dust collector (dust removing) → powder selector (powder selecting) → finished sand.
Advantages: the powder separator is used to separate the sand and powder from the finished mechanism sand, no water is needed, so the production cost is lower; at the same time, the fine powder can be recycled through the dust collector and powder separator, which can be used for road bedding or raw materials of slag bricks, so the utilization rate of resources is higher.
Disadvantages: the air in the production workshop is dry, dust spillage, dust phenomenon is obvious, will cause dust pollution, need to configure dust removal equipment.
2.Wet sand process
Raw material → vibrating feeder (feeding) → jaw crusher (coarse crushing) → cone crusher / impact crusher (medium and fine crushing) → vibrating screen (screening large aggregates) → sand making machine (sand shaping) → vibrating screen (screening small aggregates) → sand washer (sand washing) → finished sand.
Advantages: the use of sand washing machine cleaning and sorting, with a large amount of water rinsing, no dust pollution in the production environment, the mechanism of the finished sand is clean and tidy, better gradation, high quality.
Disadvantages: sand production uses more water and is limited by the location of the water source; the cost of sand washing water and sewage treatment has increased the production cost.
B. How to choose between dry and wet sand making?
When choosing sand making process, we can synthesize the water resources of the region we are located in, raw materials and material requirements to choose. Wet sand making process, with large water consumption, is mostly used in rainy or water-rich areas; dry sand making process, with small water consumption, is mostly used in arid areas with little rain or water shortage.
However, from the environment and cost considerations, in the lack of water resources, effective control of the mechanism of sand mud powder and other harmful substances content, dry sand less water consumption, higher yield, lower cost, and not affected by the season and other factors, more popular with customers.
Dry sand and wet sand equipment used in similar equipment, only the difference between the selection of sand washing machine and powder selector, in the purchase cost of the two is not much difference, but in the later operation of dry sand is relatively low. Due to the type of sand making equipment, more models, customers on the sand production line output requirements are different, to understand the specific sand program and price, you can directly click on the online consultation.
