What is the working principle of the stone powder making machine

The stone powder making machine consists of several key components, including the mill body, blower fan, ultra-fine analyzer, finished product cyclone container, bag de-duster, and air pipe. Optional components may include an elevator, storage bin, electric control cabinet, powder feeder, and crusher, based on customer demands.

During operation, the main bearing and dials are powered by electricity through a reducer, driving all the grinding rollers to rotate within the ring channels via plungers. Centrifugal force propels the materials to the edge of the turn plate, where they fall into the grinding chambers. A high-pressure air blower continuously inhales air, bringing airflow mixed with crushed materials to a classifier with a high-speed impeller to screen the airflow. Unqualified particles fall and return to the mill, while qualified particles mixed with air enter the cyclone powder collector.

Most of the qualified powders exit from the discharging valve at the bottom, and a small proportion of fine powders, carried by airflow, move to the dust cleaner. These materials are then conveyed by a conveyor for final packing. Additionally, filtered clean air is emitted from a muffler at the end of the process. This working principle allows for efficient grinding and separation of materials.

What are the primary applications of stone powder made by the stone powder making machine

Stone powder produced by the stone powder making machine has a wide range of applications in various industries. It is commonly used in everyday products such as clothes, toothpaste, plastics, cosmetics, food, and pigments. Additionally, stone powder finds its use in industrial applications, including ceramics, cement, glass, refractory materials, smelting, papermaking, and coatings. Even the pharmaceutical industry relies on stone powder in certain medicinal formulations. In summary, stone powder has diverse applications and plays a significant role in various sectors.

Which types of stones are suitable for grinding into powder using the stone powder making machine

The stone powder making machine is suitable for grinding a variety of crisp materials with a Moh's hardness below 7. These materials include but are not limited to calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, white mud, mica, refractory materials, and glass, totaling around 1000 different materials. It's essential to ensure that the stone being ground meets these criteria to achieve the desired results efficiently.

What are the advantages of the stone powder making machine compared to other grinding equipment

The stone powder making machine offers several advantages over traditional grinding equipment:

1. Enhanced Efficiency: It has double the capacity of a jet mill, mixing grinder, and ball mill with a 30% reduction in energy consumption for the same finished final size and motor power.
2. Durable Components: The ring and roller are forged from special materials, extending the lifespan of spare parts, making them last about one year, which is 2-3 times longer than an impact mill or turbo mill. For grinding calcite carbonate, the lifespan can reach 2-5 years, with variability based on material hardness.
3. Reduced Maintenance Issues: The absence of rolling bearings or screws in the grinding cavity eliminates problems caused by bolt shedding or rapid wear of bearings and seal components.
4. Adjustable Fineness: It allows for the adjustment of the final fineness of grinding materials within a wide range, from 150 meshes to 3,000 mesh (74-5 microns).
5. Minimized Pollution and Noise: The application of pulse bag filters and mufflers greatly reduces dust pollution and noise, enhancing the environmental friendliness of the process.
6. Efficient Material Feeding: The machine enables even material feeding and the adjustment of the main speed to match the ground material, resulting in more stable fineness, increased capacity, and reduced power consumption.

These advantages make the stone powder making machine an excellent choice for ultra-fine powder processing, outperforming other grinding equipment in many aspects.
