Product Introduction: Polyacrylamide Specifically for Coal Washing
Overview
Introducing our specialized polyacrylamide for coal washing, a chemical formulation fine-tuned to outperform generic polyacrylamides by several multiples. Tailored for coal washing filtration and groundwater drainage, it delivers immediate precipitation results within approximately 5 seconds. This rapid efficacy has earned it widespread adoption among coal mines as their preferred flocculant.
Purpose of Coal Washing
The fundamental objectives of coal washing are to reduce ash content, eliminate impurities, enhance coal quality, and safeguard the environment. Put simply, coal washing facilitates coking—combining coals of various compositions for coking processes. The process involves segregating coals into different grades based on their inherent compositions, leveraging water buoyancy to separate coal from gangue. This industrial process purifies raw coal by removing impurities.
Products of Coal Washing
The outcomes of coal washing typically include gangue, middling, B-grade cleaned coal, and A-grade cleaned coal. The finished product, often referred to as cleaned coal, is characterized by low ash and sulfur content and high calorific value.
Chemicals Used in Coal Washing
The coal washing process employs a suite of chemicals: frothers, flotation agents, defoamers, water, heavy liquids, and, for subsequent treatments, flocculants (polyacrylamide as a flocculant), aluminum sulfate, ferric sulfate, and their polymers as coagulants. Alternatively, polyaluminium chloride (PAC) serves as a coagulant and filter aid. In cases of severe sliming, the use of flocculants alone may yield limited results, necessitating the prior addition of coagulants to disrupt colloidal structures, followed by flocculants (polyacrylamide). PAC is also utilized as a filter aid in the dehydration stage to enhance dehydration efficiency. To expedite coal slurry sedimentation in thickening tanks, ensuring quality wash water and filter-pressed coal slime production for efficient and economically viable operations, selecting the appropriate flocculant to strengthen coal slurry treatment is imperative.
Proven Efficacy
Recent coal washing site water treatment practices have demonstrated that our specialized polyacrylamide for coal washing exhibits superior performance in coal slurry treatment, accelerating coal slime settlement and facilitating filter pressing production.
