Do you know how coconut shell charcoal powder is made?
After carbonization, coconut shell charcoal enters the core transformation stage—the grinding workshop of Shibang Machinery's MTW series European-style grinding mill. This intelligent grinding equipment, incorporating multiple patented technologies, achieves a leap in charcoal powder quality through three innovative mechanisms:
Three-dimensional grinding system: Utilizing an integrated bevel gear transmission design, the grinding rollers form a 360° circular grinding path under centrifugal force. Compared to traditional grinding mills, this system increases grinding efficiency by 30% and reduces specific energy consumption by 18%. The strong compression of the grinding rollers and grinding rings fully releases the internal pore structure of the carbonized material.
Intelligent grading control: The built-in eddy current classifier is equipped with a variable frequency speed control device to precisely control the fineness of the finished product. The freely adjustable grading accuracy within the 80-400 mesh range ensures a D97 pass rate of over 98% for the final charcoal powder. A specially designed secondary circulation air duct increases the recovery rate of ultrafine particles to 99.5%. Environmentally friendly dust removal system: The pulse dust collector utilizes nano-scale filters, coupled with a negative pressure collection system, to achieve a dust emission concentration of less than 5mg/m³ in the workshop. Waste heat generated during the grinding process is recovered through a heat exchanger and used in the raw material drying process, forming a closed-loop energy-saving system.
Quality Enhancement: From Black Powder to Green Value
The coconut shell charcoal powder, finely processed by the Shibang mill, achieves a qualitative leap in physical properties: its specific surface area increases from 300-500m²/g of carbonized material to 1200-1800m²/g, its iodine adsorption value exceeds 1000mg/g, and its methylene blue adsorption value reaches over 200mg/g. These microstructural optimizations enable superior performance in the following areas:
Water treatment: Its heavy metal ion adsorption capacity reaches 120 mg/g, and its daily wastewater treatment capacity exceeds 500,000 tons in the Taihu Lake Basin Reclamation Project.
Air purification: Its developed honeycomb activated carbon filter achieves a formaldehyde removal rate of 98.7% and a service life three times that of traditional materials.
Energy storage: As a supercapacitor electrode material, its specific capacitance reaches 180 F/g and its cycling stability is excellent.
From waste on tropical coasts to "black gold" in the environmental protection sector, Shibang Machinery has unlocked the ultimate value of coconut shell charcoal through precision grinding technology. Each MTW mill can process up to 50,000 tons of carbonized material annually. The high-quality carbon powder it produces is continuously injecting green energy into the global environmental protection industry, writing a modern legend in resource recycling.
