【引言】
煤炭洗选加工过程中,会产出大量煤泥副产品。煤泥颗粒细、粘度高、持水性强,一直是洗煤、工矿企业头疼的固废处置难题。露天堆存隐患重重,传统处置手段治标不治本,一边要承受环保督查压力,一边大量可利用资源白白浪费。如何把高湿结块煤泥实现减量化处置、资源化回收,成为众多工矿企业迫切需要解决的现实问题。
shing plants and industrial and mining enterprises. Open‑pile storage carries severe hidden dangers, and traditional disposal methods offer only temporary relief rather than a fundamental solution. While enterprises face pressure from environmental inspections, substantial usable resources are wasted. Achieving volume reduction treatment and resource recovery of high‑moisture agglomerated coal slime has become an urgent practical problem for numerous industrial and mining enterprises.

一、工矿行业真实痛点:煤泥堆存处置多重压力
经过压滤后的湿煤泥含水率居高不下,物料粘性强,极易抱团结块。露天堆放模式下,风吹就起扬尘污染,遇雨水冲刷,煤泥四处流失,产生大量煤泥渗滤液,污染厂区土壤与周边水体,带来突出的环保风险。
煤泥本身具备一定热值,属于可回收利用资源,但高水分状态下无法直接掺烧、外销。大量堆料占用厂区大片场地,企业既要承担堆场建设维护成本,还要时刻面临环保巡查,一旦管控不到位,就会触发整改、处罚,给企业正常生产经营带来很大不确定性。
I. Real Pain Points in the Industrial and Mining Sector: Multiple Pressures from Coal Slime Stockpiling and Disposal
Filter‑pressed wet coal slime maintains high moisture content and strong material viscosity, making it prone to clumping. Under open‑air storage, wind triggers dust pollution, while rainwater washing causes coal slime to spread and form large volumes of coal slime leachate, contaminating on‑site soil and surrounding water bodies and creating prominent environmental risks.
Coal slime itself has a certain calorific value and counts as recyclable material. However, its high moisture prevents direct co‑firing or external sales. Large stockpiles occupy extensive plant space. Enterprises bear costs for yard construction and maintenance while remaining subject to routine environmental inspections. Inadequate control may lead to rectification orders and penalties, introducing great uncertainty to normal production and operation.
二、传统处置短板多,很难适配现代化工矿生产
很多工矿企业尝试过各类传统处理方式,但都存在明显短板:
✅露天自然晾晒:需要超大堆放场地,完全看天气,雨雪天气完全无法作业,晾晒周期漫长,煤泥容易二次结块,扬尘管控难度大,很难实现规模化稳定产出。
✅直接外运处置:需要承担高额运输费用,湿煤泥运输途中滴漏污染,合规运输管控严格,对外处置成本持续走高,只出不进,持续增加企业负担。
✅简易烘干设备:普通单筒设备处理高粘煤泥极易粘壁糊料、堵料停机,烘干干湿不均,故障率高,连续生产难以保障,后期运维成本居高不下。
传统模式下煤泥处置只有投入没有收益,固废负担持续拖累企业生产效益。
II. Many Drawbacks of Traditional Disposal Methods, Poor Compatibility with Modern Industrial and Mining Production
Many industrial and mining enterprises have tried various conventional treatment approaches, all with obvious shortcomings: ✅ Open‑air natural airing: Requires enormous stacking space and is completely weather‑dependent. Operations halt entirely in rainy or snowy weather. The airing cycle is lengthy; coal slime easily re‑agglomerates, dust control is difficult, and stable large‑scale output is hard to achieve. ✅ Direct off‑site disposal: Incurs high transportation expenses. Wet coal slime tends to leak during transit, subjecting transport to strict compliance controls. External disposal costs keep rising, generating only outflows and continuously increasing corporate burdens. ✅ Simple drying equipment: Ordinary single‑cylinder units handling high‑viscosity coal slime suffer severe wall adhesion, material caking and blockage‑related shutdowns. Drying results are uneven, failure rates are high, continuous production cannot be guaranteed, and long‑term operation and maintenance costs remain high.
Under traditional models, coal slime disposal brings only expenditure with no revenue, and the solid waste burden persistently drags down production benefits.

III. Jinwanhong Special Single‑Cylinder Drying Process for Coal Slime: Simple, Efficient and Tailored for Mandatory Industrial and Mining Working Conditions
For small and medium coal washing plants and industrial and mining enterprises with moderate coal slime disposal budgets, limited site space and demands for high stability, Jinwanhong’s special single‑cylinder coal slime dryer adopts an integrated large‑diameter long cylinder structure. Unlike ordinary simple single‑cylinder equipment, it is specially optimised for high‑moisture, high‑viscosity coal slime.
The machine adopts a concurrent high‑temperature rapid drying process. Hot air and wet coal slime enter the cylinder in the same direction, instantly penetrating the surface layer of high‑water material and quickly removing free surface moisture. Relying on the long‑stroke cylinder structure, it extends the material drying path and gradually removes internal bound water, thoroughly solving the common issue of partially dried coal slime that is dry outside yet wet inside.
The complete machine features a simple structure, low failure rate and easy maintenance. It has no complex nested components, low heat loss and fast heat‑up for high commissioning efficiency. It perfectly meets industrial and mining enterprises’ requirements for continuous, large‑volume and low‑cost coal slime drying. Compared with ordinary simple equipment, it delivers greatly improved drying stability and finished product qualification rates.
四、定制化防粘扬料结构,攻克煤泥粘壁结块难题

金万泓针对煤泥物料做专项结构优化,搭载定制化扬料打散、防粘清扫装置。在筒体旋转过程中,持续打碎成团湿煤泥,把物料充分扬起形成均匀料幕,减少物料贴壁粘附,降低堵料风险,保障设备长时间连续运行,减少人工清理频次,降低停机损失。物料与热风充分接触,烘干更充分,规避成品夹生、干湿波动大的问题。
IV. Customised Anti‑Sticking Lifting Structure to Tackle Coal Slime Wall Adhesion and Agglomeration
The biggest difficulty in coal slime drying lies in the material’s high viscosity, which easily adheres to cylinder walls and accumulates in clumps, causing frequent shutdowns for cleaning.
Jinwanhong has optimised the structure specifically for coal slime, equipped with customised material lifting, breaking and anti‑sticking cleaning devices. As the cylinder rotates, it continuously crushes clumped wet coal slime and fully lifts the material to form a uniform material curtain. This reduces wall adhesion, lowers blockage risks, enables long continuous equipment operation, cuts manual cleaning frequency and minimises shutdown losses. Full contact between material and hot air ensures thorough drying and avoids under‑dried finished products and large fluctuations in moisture levels.

VII. Coal Washing Plant Implementation Case: Single‑Cylinder Drying Put into Service, Turning Coal Slime into Resources to Cut Costs and Boost Revenue
Many small and medium coal washing plants once faced massive coal slime disposal pressure. Open‑air stockpiling occupied large areas, carried high risks of dust and rainwater pollution, and off‑site transport costs rose year by year, resulting in perennial losses from solid waste disposal.
After installing Jinwanhong’s complete special single‑cylinder coal slime drying equipment, high‑moisture filter‑pressed coal slime can be fed directly into the machine for drying without pre‑airing pretreatment. The equipment runs stably with minimal wall adhesion or blockage, simple operation and maintenance and low labour costs. Dried coal slime features uniform moisture, loose dry texture and stable calorific value. It can be directly used for co‑firing in on‑site boilers to reduce procurement costs of external fuel, or sold externally as building material or fuel raw material to generate steady incremental revenue.
Following project implementation, the plant completely eliminates the chaos of open‑air coal slime stockpiling, clears solid waste stockpiles and removes environmental risks. The solid waste burden that used to cost money every year has been successfully converted into high‑quality recyclable resources, truly achieving triple benefits: compliant production, reduced consumption and costs, and value appreciation and revenue growth.
