Ⅰ. Sand washing process
The sand washing equipment achieves efficient cleaning of machine-made sand and the recovery of fine sand through a series of precise process steps. After being crushed, sand made and screened, the mechanism sand firstly enters the wheeled type sand washing machine by a conveyor. In the sand washer, sand and gravel rub against each other through the transmission device to remove soil and impurities on the surface. At the same time, the water flow also plays a further cleaning role. During this process, the water vapor layer on the surface of the sand and gravel is destroyed, and impurities are effectively removed.
The cleaned sand and gravel are discharged from the overflow port of the sand washer, while the generated mud enters the fine sand recovery machine for further processing.The fine sand recycling machine achieves effective recovery of fine sand in mud through grading technology, avoiding the waster of resources. At the same time, the sewage sedimentation tank carries out sedimentation treatment on the mud and sewage to ensure that the discharged water quality meets environmental standard, thus realizing the environmental protection of the sand washing process.  


Ⅱ. Cost analysis of sand washing equipment
The composition of sand washing equipment is relatively simple, mainly including wheeled type sand washing machine, fine sand recovery machine, and conveyor. This configuration ensures the efficiency of the sand washing process and also reduces the cost of equipment. Generally speaking, the price of a complete set of sand washing equipment is around 100000 yuan, but the specific price will vary depending on the model and configuration of the equipment.
It is worth noting that the larger the model of the device, the stronger of its processing capacity, but the corresponding price will also be higher. Therefore, investors should consider their own production needs and budget comprehensively when choosing equipment. In addition, the quality and performance of the equipment are also important factors affecting the price. Choosing the equipment with excellent quality and stable performance can not only improve production efficiency, but also reduce maintenance costs in the later stage.

In summary, although the sand washing equipment seems simple, its sand washing process and cost analysis involve multiple factors. When choosing equipment, Investors should fully understand the information of the equipment such as the performance, price, and after-sales service, to ensure that their investment can get the maximum return. At the same time, we should also pat attention to environmental policies and market dynamics to cope with potential challenges and opportunities.
