HCM Humic Acid Milling Equipment Factory learned that Brazil's Massari Fértil recently launched a patented humic acid activation technology and a brand-new fertilizer product line, achieving significant yield increases for various crops. Brazil's agriculture faces problems such as climate change, soil degradation and insufficient fertility. These issues are particularly prominent in the Cerrado region, where the acidic and low-fertility oxisols relied on for agricultural expansion require extensive improvement and fertilization solutions.

It is known that for a long time, the utilization of phosphogypsum has been concentrated in low-value-added fields such as traditional building materials. The price of phosphogypsum powder used in the building materials industry in India is about 43-133 US dollars per ton, while in Egypt, the price of 80-200 mesh phosphogypsum powder used in gypsum boards, plastering and other building materials fields is 55-75 US dollars per ton, and the price of ordinary phosphogypsum powder in Vietnam is 52-70 US dollars per ton. How to extend to high-end material fields and increase product added value is the key to solving the problem of insufficient resource utilization of phosphogypsum.

This solution leverages HCM's three decades of expertise in powder grinding equipment R&D and industrial solid waste management. Addressing the challenges of massive steel slag emissions, low resource utilization rates, and low added value in steel enterprises, it integrates a full-chain technology encompassing "steel slag pretreatment, efficient scrap steel recovery, graded grinding, and high-value applications." The core equipment, including HCM's HLM series vertical grinding mills, achieves 100% resource utilization of steel slag. This process not only recycles high-grade scrap steel for steelmaking but also produces premium steel slag micro-powder for the construction industry, helping enterprises reduce costs, improve efficiency, and achieve green transformation. The solution aligns with China's "dual carbon" goals and industrial solid waste resource utilization policies.

HCM Grinding Mill has successfully implemented a 660,000 t/a cement production project utilizing co-processing grinding mills for solid waste. The project includes: 500,000 t/a cement kiln co-processing of solid waste replacing 366,000 t/a conventional raw materials, and 160,000 t/a cement grinding station using solid waste to substitute 160,000 t/a conventional blended materials.

The HCM Raymond mill is capable of grinding marble ore into fine powder ranging from 80 to 400 mesh. The models available for marble grinding include HC800, HC1000, HC1300, HCQ1500, HCQ1850, HCQ2000, HCQ2300, HCQ2600, and HC3000. What is the maximum output capacity of these models for marble grinding? What are some notable engineering applications?

Calcined petroleum coke (CPC) is a product obtained by high-temperature calcination (typically 1200-1450°C) of raw petroleum coke. During the calcination process, moisture, volatiles, sulfur (partially), and impurities are removed from the raw coke, resulting in a volume-stable, low-resistivity, and chemically purified material with a dense structure. It serves as a core raw material for producing prebaked anodes, graphite electrodes, metallurgical coke, and other products used in electrolytic aluminum production.

HCM Raymond Mill Factory manufactures Raymond Mill bases in two variants: split-type and integral-type. These bases serve as the structural foundation supporting core components including the main unit, motor, and transmission system. Their design and manufacturing processes directly determine the equipment's operational performance, with the most common types being these two categories.

In industrial production, coal powder serves as an important fuel and raw material, and its grinding fineness and output directly affect subsequent production efficiency and cost control. Whether in the power, building materials, or chemical sectors, the demand for conventional fine coal powder with 45μm particle size is growing steadily.

The HCM mill's 74μm lignite powder project has recently commenced operations. Utilizing the HC series 1700 Raymond mill developed by HCM Mill, this lignite grinding process achieves 74μm fineness with a 15t/h output. The resulting 74μm lignite powder, characterized by its fine particle size and high reactivity, is compatible with multiple industries requiring precise material fineness, including

The smallest models of HCM Raymond mills are HC800 and HC1000. The HC800 small Raymond mill has 3 grinding rollers, the nominal diameter of the grinding ring is 800mm, the maximum feed particle size is ≤15mm, the grinding ore output is 0.3-3t/h, and the power of the whole machine is 49.5kw. The HC800 small Raymond mill grinds activated carbon to 45μm, with an hourly output of about 1.2 tons;
