In recent years, with the continuous improvement of the "ban on mining" of river sand, most provinces are currently promoting and marketing the use of mechanical sand and gravel. However, regarding the selection of production process for stone production lines, the dry sand production line is favored by everyone due to its characteristics such as being not limited by the ecological environment and zero sewage treatment.
The dry sand production line, in simple terms, refers to the production process of machine made sand and gravel, where there is no tap water to clean up the smoke and dust inside the sand. Instead, a powder concentrator is used to separate the machine made sand and dust, in order to obtain a relatively reasonable mix ratio of finished machine made sand and gravel.

The important role of using a powder concentrator manufacturer's powder concentrator in the sand making process is to separate and solve unused lime powder and meaningful particles, and treat them separately. The principle of a powder concentrator is to mix gas and powder to produce a gas-solid two-phase flow. The rotating powder tray and high-pressure gas cause the powder containing cyclone to obtain centripetal force during rotation. Different particle sizes and particle sizes achieve different centripetal forces, thus achieving the separation of size and size. In addition, the corresponding method is used to recycle and utilize the large and small powders in sequence. Meaningful particulate matter refers to finished sand, which can be stored in a stone powder silo through a large and small powder separator without using ultrafine powder.
The role of the powder concentrator manufacturer's powder concentrator
1. The lime powder content in the finished sand after powder selection by the powder selection machine of the powder selection machine manufacturer varies with the changes in the lathe speed and fan air volume of the powder selection machine. Adjusting the basic parameters of the powder selection machine can effectively control the lime powder content in the finished sand.
2. Under the same basic parameters, the lime powder content in the finished sand can be controlled within a relatively stable range while ensuring the stable feeding of the powder selection machine.
3. The total feed flow rate, lime powder content, and water content of genuine sand are all key factors that endanger the powder selection ability and actual effect of the powder selection machine. When the water content of the feed does not exceed 2%, the powder concentrator can effectively achieve high efficiency.
4. By adjusting the feed speed of the powder selection machine and the air volume of the fan, the lime powder content in the finished sand can be controlled within the range of 18 ± 2%.
Henan Huayi, as a manufacturer of equipment for dry sand production lines, continuously explores, researches and experiments, and has created a small elevator gas powder concentrator. This powder selection machine is mainly used in the production line of dry trial shaping and beauty stone materials. Its core function is to more effectively remove the impurities of ultrafine powder from items, making the grading of finished sand more scientific and standardized.
Characteristics:
1. The connection structure between the powder concentrator and screening equipment is compact, ensuring the smooth operation of professional equipment.
2. Using wear-resistant lining board as the lining, it is not easy to damage and is sturdy and durable.
3. There are no rotating components inside, maintenance is simple and practical, and the equipment failure rate is low.
4. Using negative pressure actual operation (i.e. gas entering the internal structure of professional equipment) to generate dust and outflow, meeting environmental regulations.
