Sand washing is an important link and main means to improve the quality of machine-made sand. The sharp rise in the sand and gravel market has driven sand washing plants to join the "profiteering" team. So what are the profits of machine-made sand washing? What equipment is generally used for machine-made sand washing?

1. Profit of machine-made sand washing

   There are two main types of sand washing plants. One is to purchase sand directly and clean it through a sand washing machine. This type of sand washing plant has low investment cost and generally only requires 1-3 sand washing machines. In terms of operation, the purchase cost of each sand washing machine is about 100,000-200,000 yuan;

   The other is a sand washing plant that directly combines sand making and sand washing production lines. This kind of sand washing plant has a large production scale and high initial investment. Generally speaking, the investment capital for such a sand washing production line is about hundreds of thousands to millions of yuan, but the profits in the later period are also greater.

   So how much money can you make from machine-made sand washing in a year? In the stage when the price of machine-made sand is rising steadily, the price of machine-made sand after washing can increase by 20-30 yuan, allowing you to buy low and sell high. Therefore, whether it is a small sand washing plant or a large sand washing plant with a large initial investment, it can basically recover the cost within 3-6 months and achieve sustained profits.

2. What equipment is used for machine-made sand washing?

   Sand washing machine is the main equipment in the sand washing process. There are so many types of sand washing machines on the market that it is dazzling. Zhengzhou Global Heavy Industry recommends wheel sand washing machine.

   Wheel sand washing machine, also known as wheel bucket sand washing machine, consists of wheel bucket, reduction box, motor, water tank, screen and other parts. Vertical structure, small footprint, strong cleaning ability and low sand washing loss rate. There are many types of low, single wheel, double wheel, three wheel and so on to choose from.

Working principle of wheel sand washing machine

   When the wheel sand washing machine is working, the impeller rotates slowly under the action of driving force. The sand and gravel are brought into the groove by the impeller. They roll in the impeller, grind and clean each other, and remove impurities covering the surface of the sand and gravel. At the same time, the water vapor layer covering the sand is destroyed, thereby dehydrating; at the same time, the large flow of water causes impurities and foreign matter with small specific gravity to be taken away by the water flow at the outlet, and the clean sand and gravel are discharged from the overflow outlet washing tank, completing the Cleaning of sand and gravel. sand.

  Environmental protection issues of cleaning mechanism sand washing

The problem of sewage treatment during the sand washing process is a headache, but in fact this problem is not as terrible as imagined. As long as the emission standards are met, there won't be much of a problem.

   In addition, the recycling of wastewater and water resources can be realized by building a sedimentation tank. The settled sludge can be transported to the sludge drying field for drying and landfill without polluting the environment.
