What is a completed phosphogypsum vertical roller mill?

A completed phosphogypsum vertical roller mill is a machine used for grinding phosphogypsum into fine powder. Phosphogypsum is a byproduct of the production of phosphoric acid from phosphate rock. It contains gypsum, phosphoric acid, and other impurities. The vertical roller mill is a type of grinding machine that grinds materials by rotating a large, vertical roller while applying grinding pressure. This machine is used to process large quantities of phosphogypsum into a fine powder that can be used in a variety of applications, such as fertilizer production, construction materials, and cement production. A completed phosphogypsum vertical roller mill includes all the necessary components and parts, such as the grinding table, rollers, drive system, and control system, and is ready for operation.

The principle of the phosphogypsum vertical roller mill is to grind materials by rotating a grinding table and applying hydraulic pressure to the rollers that are pressed against the grinding table. The grinding table, which is driven by a motor, rotates around its axis, and the rollers rotate around the grinding table. As the rollers rotate, they apply pressure to the grinding table, and the material is crushed and ground between the rollers and the table.

The hydraulic pressure is used to adjust the grinding pressure of the rollers against the grinding table, which is important for achieving the desired fineness of the ground material. The grinding pressure can be adjusted to a high level, which allows the machine to grind hard materials, such as phosphogypsum, into a fine powder.

The ground material is transported to the classifier, which separates the fine powder from the coarse particles. The fine powder is collected in a dust collector and then transported to a storage silo or directly to the production process. The coarse particles are returned to the grinding table for further grinding, ensuring that all the material is ground to the desired fineness.

Sure, here is a model list for phosphogypsum vertical roller mill:

1. LM130K

2. LM150K

3. LM170K

4. LM190K

5. LM220K

Each of these models differs in their grinding capacity and motor power. It is important to select the appropriate model that fits the specific needs and requirements of the phosphogypsum milling process.

The cost of a phosphogypsum vertical roller mill varies depending on multiple factors, such as the model, capacity, and manufacturer. In addition, factors such as installation and maintenance costs, as well as the location of the mill, can also affect the overall cost.

Generally speaking, the price range for a phosphogypsum vertical roller mill can vary from tens of thousands to several hundred thousand dollars, depending on the aforementioned factors. It's best to consult with a reputable manufacturer or supplier to get an accurate quote for the specific needs of your milling process.
