Coal Toothed Roll Crusher Crushing Effect Analysis
Coal Toothed Roll Crusher has outstanding performance in the field of coal crushing, with its unique design and efficient performance, it has become the mainstream equipment for crushing coal, coke, coal gangue and other materials. The following is a comprehensive analysis of its core features and advantages:
Coal Toothed Roll Crusher
1. Working Principle and Structural Design
Crushing Mechanism
Through the two relatively rotating rolls, it applies squeezing force, shearing force and splitting force to the material to achieve ‘selective crushing’. The material is forced to be crushed in the gap between the rolls (V-shaped crushing chamber), and the qualified size is directly leaked down to reduce over-crushing.
Core structure features
Non-equal circle, non-meshing, differential speed operation: enhance the shearing effect, reduce the risk of clogging.
Hydraulic adjustment system: flexibly control the gap between the rollers, and precisely adjust the size of the discharged material (usually 10-50mm).
Multiple protection devices: hydraulic coupling anti-overload, sensor overload protection, hydraulic setback device (to prevent iron/wood blocks from damaging the equipment).
2. Performance Advantages
High efficiency and energy saving
Large crushing ratio (5-8), one crushing can meet the particle size requirements, energy consumption is more than 30% lower than the traditional crusher.
The productivity is 1-2 times higher than the traditional 2PGC Toothed roll crusher, and the hourly output of a single machine can reach 30-400 tonnes.
High output quality
Uniform and controllable particle size, overcrushing rate is less than 10%. Reducing the generation of powder (compared with the hammer crusher dust reduction of more than 50%).
Optimised tooth design (trapezoidal teeth, wave teeth, etc.). To adapt to different materials, such as trapezoidal teeth to deal with large gangue, wave teeth to cope with wet and sticky materials.
Durability and convenient maintenance
The tooth plate is made of high chrome alloy wear-resistant material. Which extends the service life by 2 times compared with the ordinary roller skin and reduces the replacement frequency.
The modular design supports quick replacement of the tooth plate, and the centralised bearing lubrication system reduces maintenance time.
Environmental protection and adaptability
Low noise (<85dB), low vibration, in line with mining environmental requirements.
It can handle raw coal containing impurities (gangue, iron lumps) without pre-screening. And materials with high water content are not easy to be clogged.
3. Applicable scenes
Coal industry: coarse/medium crushing of raw coal, coke, gangue, simplify the coal selection process.
Multi-industry expansion: metallurgy (sinter ore), building materials (limestone, shale), chemical industry (petroleum coke) and other low hardness brittle materials crushing.
4. Tooth design and selection
Selection of tooth shape according to material characteristics:
Trapezoidal teeth: high crushing ratio, coarse grain size output (such as large gangue).
Serrated teeth: fine crushing of medium hardness materials (e.g. coke).
Wave teeth: high gripping force, suitable for wet and sticky materials (such as raw coal with water content >15%).
With the advantages of high efficiency and energy saving, even material discharge and low overcrushing rate, the Coal Toothed Roll Crusher has become the ideal choice for coal crushing. Its modular design reduces maintenance costs and multiple protection mechanisms enhance safety, especially suitable for continuous operation of materials containing impurities or high humidity. When selecting a model, it is necessary to match the tooth shape and model according to the processing capacity and material characteristics (hardness, moisture content), and give priority to the new model equipped with intelligent control system to enhance long-term benefits.
