Product Introduction
Vertical multi-stage coarse powder machine, also known as vertical coarse powder machine or multi-stage coarse powder machine, abbreviated as coarse powder machine, is a professional product that processes various mineral materials into fineness between 20 and 120 mesh, and can also process machine made sand between 4 and 20 mesh, but the two products are different.
In industrial powder processing, the coarse powder within the range of 20-120 mesh is the most difficult to control, either the finished product particle size is too large or the grinding is too fine. In response to this phenomenon, some companies have conducted experiments on various mineral materials and concluded that the powder grinding equipment within the range of 20-120 mesh is a vertical multi-stage coarse powder machine, which has an ideal effect.
We can be divided into two types based on the hardness, specific gravity, and other characteristics of mineral materials, namely heavy vertical multi-stage coarse powder machines and light vertical multi-stage coarse powder machines, according to their internal structures. Among them, heavy vertical multi-stage coarse powder machines are the ideal equipment for professional grinding of high hardness ores such as river pebbles, granite, basalt, iron ore, and silica.
Performance characteristics
1. The material is not affected by moisture and does not block the machine;
2. Adjustable speed, controllable proportion of finished product fineness;
3. Large single machine output, high yield, and less powder under the 120 mesh sieve;
4. The feed particle size limit is small, and both small and large materials can be processed;
5. Closed operation, equipped with dust collection equipment, environmentally friendly and good;
6. Moderate price, low power consumption, and low usage cost;
Technical Parameter
| Model number | Diameter(mm) | Handling capacity(t/h) | 20 mesh sifting rate(%) | Power(kw) |
| AQS-800 | 800 | 5-10 | ≥80 | 37-45 |
| AQS-1000 | 1000 | 10-15 | ≥80 | 45-55 |
| AQS-1250 | 1250 | 15-25 | ≥80 | 75-90 |
| AQS-1500 | 1500 | 25-40 | ≥75 | 132-160 |
The above technical parameters are for reference only. If there are any changes, no further notice will be given. Our company's current new technical parameters shall prevail! According to different raw materials and finished product particle sizes, there may be slight differences in production. The feed particle size can reach 10-15 cm, but it is recommended to control the ideal feed particle size below 3-5 cm and support customization according to needs!
operational principle
The material passes through some feeders on the machine and evenly falls into the high-speed rotating machine cavity. Under the high-speed impact and centrifugal force of the grinding block, the material is thrown out at high speed and collides and grinds with the surrounding lining plate. After hitting and colliding with each other, the material will collide and rub with each other multiple times between the grinding block and the lining plate through the eddy current formed by the material, resulting in crushing. It undergoes four identical operations from top to bottom, and finally is discharged directly from the bottom, Forming a closed circuit with multiple cycles, the finished product is controlled by the speed and screening equipment, and the particle size required by the user is transported to the finished product area.
Our vertical multi-stage coarse powder machine is different from the horizontal European coarse powder machine. Its discharge particle size is controllable and adjustable, and the proportion of fine powder under the 120 mesh sieve is relatively small. The proportion can be flexibly controlled according to user requirements!
The vertical multi-stage coarse powder machine mainly processes finished product particle size ranges: 10-20 mesh, 20-40 mesh, 30-70 mesh, 40-80 mesh, 70-120 mesh, 80-140 mesh, etc. Among them, the proportion between 30-70 mesh and 70-120 mesh is balanced!
This machine mainly solves the shortcomings of the horizontal European version coarse powder machine, which processes products that are too fine and has a lot of material under the 120 mesh sieve!
