Coal, as a basic solid combustible mineral, has uneven and large-sized raw coal blocks after extraction, which cannot be directly sent to downstream processes such as power plants, coal chemical plants, and coal washing plants.
If you are engaged in coal processing, coal selection, or solid waste treatment, you must be aware that for raw coal to have value, crushing and classification are an indispensable step.
Traditional crushing equipment is prone to problems such as over-crushing, blockage, and large fluctuations in finished product particle size, which can affect the stable operation of the entire production line. However, our Coal Mineral Sizer is a classification and crushing equipment specifically developed for brittle materials like coal.
Now, let's break down its core functions, application scenarios, and product advantages based on the entire coal processing process.
What is the Coal Mineral Sizer?
The EXCT Coal Sizers uses the combined action of toothed rollers for shearing, compression, and stretching to complete material crushing, which is significantly different from the working method of impact crushers.
It is not just a simple crusher but an integrated crushing and pre-sieving equipment. The biggest feature of this equipment is controllable crushing, with strict control of over-crushing rates.
In simple terms, it does not merely make the material finer but produces stable finished materials with uniform particle size according to your production requirements.
Coal Mineral Sizer Core Purposes
Precise Control Of Particle Size
Different downstream scenarios have completely different requirements for the size of coal particles.
You can adjust the equipment parameters to break large raw coal into the specified particle size, respectively adapting to various demands such as power plant fuel coal, coking raw coal, washed raw coal, and lump coal products.
The shearing crushing mechanism can effectively reduce coal powder generation, avoid over-crushing causing raw material loss, and reduce on-site dust, helping to maintain the yield of lump coal products.
Crushing And Screening Integration
The EXCT coal mineral sizer has its own grading function. During crushing, the qualified particles can be directly discharged.
The large blocks exceeding the specifications will remain in the crushing chamber and continue to be acted upon by the toothed rollers until they meet the particle size requirements.
This design can prevent qualified particles from being crushed again, ensuring uniform and stable finished particle size.
Improving Production Line Efficiency
In many situations, using the EXCT Mineral Sizer, a single stage of crushing can achieve the target particle size range.
You do not need to configure multiple screening and crushing equipment in series, shortening the crushing process section.
The number of supporting equipment decreases, and the transportation points, labor maintenance workload, energy consumption will also decrease accordingly. The production line structure becomes simpler, and the risk of blockage will be significantly reduced.
Resource Utilization
In addition to coal processing, it also has an important application: treating coal-related by-product wastes.
Coal gangue, washed middle coal, coal slag, etc., when piled up, not only occupy space but also pose environmental pressure.
After crushing and processing, these solid wastes can be transformed into building materials, fuel for brick factories, or road base fill materials, helping you convert waste materials into usable resources and achieve waste reduction.
Coal Mineral Sizer Application
Coal Industry
It is widely used in underground coal mines, surface coal washing plants, and coal washing workshops.
It can undertake initial crushing of raw coal, fine coal crushing, and treatment of washed middle coal, providing particle size suitable raw materials for washing and blending production.
It can also be used to crush coal gangue alone, and be paired with a solid waste resourceization production line.
Power Industry
Thermal power generation is an important application direction.
It can be used to crush coal for preparing qualified fuel particles for circulating fluidized bed boilers and pulverized coal boilers, ensuring complete combustion of the fuel and maintaining stable operation of the boilers.
Chemical Industry
The coal-based chemical production requires strict requirements for the feed particle size.
For processes such as ammonia synthesis and coal-to-methanol, raw coal needs to be crushed to the specified particle range in advance to meet the feed standards for the gasification process.
Metallurgical Industry
The pre-treatment of fuel coal for metallurgical production is also often equipped with this equipment.
The stable and consistent fuel particle size can ensure the stable operation of the metallurgical process.
Construction Materials Industry
The brick factory is one of the main scenarios for the resource utilization of coal gangue.
The crushed coal gangue and slag can be used as internal fuel or additives for sintered bricks, helping construction materials enterprises reduce raw material procurement costs.
In addition, this equipment can also handle hard-to-machine brittle materials such as shale and construction waste. The application scenarios of the equipment are more extensive.
In summary, the core purposes of the Coal Mineral Sizer can be summarized into four points: precise customization of crushing particle size, integrated crushing and classification, simplification of production lines to reduce production costs, and resource utilization for coal-based solid waste.
It is a key intermediate equipment for converting raw coal into various industrial raw materials. While meeting the requirements of coal processing production, it also aligns with the development direction of solid waste resource utilization.
