(1) Product granularity is guaranteed

Different materials have different dissociation characteristics. The classification crusher adjusts the corresponding tooth roller center distance during crushing, strictly controls the space size of material passing, and obtains a cubic product that meets the particle size requirements. The low pulverization can greatly reduce the amount of coal at the end, so that the limited coal energy in China can be fully utilized, and the environmental pollution can be reduced while saving the cost of processing the slime water.

(2) has the dual effects of crushing and screening

The crushing and grading function of the graded crusher can reduce the separate screening process. The tasks previously completed by two-storey factory buildings with six or seven sets of equipment can be successfully completed by one graded crusher, saving infrastructure. The cost of labor and equipment has simplified the system and is beneficial to the economic benefits of the coal preparation plant. Save a lot of infrastructure and equipment investment and corresponding maintenance and repair costs for the site.

(3) Material distribution balance

The crushing roller of the grade crusher adopts computer simulation design, which not only realizes the balanced distribution of materials, but also ensures the continuity of the crushing process, avoids the material to be broken only at a specific position, and reduces local wear and blockage.

(4) Product granularity adjustable

The graded crusher has strong adaptability, and the product granularity can be flexibly adjusted according to user requirements.

(5) The whole machine has low height and no vibration

Due to its low height, no vibration and internal force balance, the graded crusher reduces the strength requirements of the plant, which is beneficial to the renovation and renovation of the plant. On the other hand, the operation is reliable, the noise is low, the failure rate is low, and the equipment maintenance is greatly reduced. Time reduces the related operating expenses and reduces the labor intensity of workers.

Time reduces the related operating expenses and reduces the labor intensity of workers.

(6) Less dust, high processing capacity and low energy consumption

The extension crusher adopts the most advanced crushing mechanism, fully utilizes the material strength characteristics, and applies crushing, puncture, shearing and other comprehensive forces to achieve crushing. During the crushing process, the material does not undergo secondary crushing, so the energy consumption is low. When crushing medium hardness materials, the jaw crusher energy consumption is generally 0.46-1.5kW·h/t, the ring hammer crusher is 0.86-1.24kW·h/t, and the impact crusher is 0.94-1.27kW·h. /t, the energy consumption of the graded crusher is 0.21-0.45kW·h/t. The material is not subjected to severe impact and impact during the crushing process. The loss rate of lump coal is greatly reduced. The residual residual stress and cracks in the crushed material are correspondingly small, and the material is broken in the subsequent processing, storage and transportation. The probability is greatly reduced, which greatly reduces environmental pollution. The grader crusher selects the direction of rotation of the two-toothed rolls, which increases the crushing passage and increases the throughput.
