What are the prominent technical advantages of the coordinate grinding machine?
1. Investment expenses for production have dropped significantly
Coordinate grinding system has simple process flow, compact planning and small construction area. It covers an area of about 70% of the ball mill system, and the construction space is about 60% of the ball mill system and can be placed in the open air, which directly reduces the company's investment cost.
And the vertical mill has its own separator, do not need to add powder separator and lifting equipment.
Dust - bearing gas can be collected directly by bag - type dust collector or electric dust collector.
2. Production, energy saving and environmental protection
The grinding principle of the material layer is low in energy consumption. The power consumption of the grinding system is 20%~30% lower than that of the ball mill. Moreover, with the addition of moisture in the material, the effect of saving electricity is more significant.
The energy consumption of vertical mill system and ball mill system can be reduced by 30% ~ 40%.
In the work of the vertical mill, there is no metal impact sound of steel balls bumping against each other and lining plate in the ball mill, so the noise is low, which is 20~25dB lower than that of the ball mill.
In addition, the vertical mill USES a completely closed system, the system works under negative pressure, no dust, environmental cleaning.
3. Strong drying ability of materials
The coordinate grinding process selects the hot air to transport the material, and can control the air inlet temperature when grinding the material with larger moisture, so that the goods reach the desired moisture.
In the vertical mill can be dried - ground into the ground water up to 15%~20% of the material.
4. Simple operation and convenient repair
Equipped with automatic control system, can realize remote control, remote coordinate boring and grinding, simple operation;
After maintenance of oil cylinder and rolling arm, roller cover and lining plate can be replaced quickly and conveniently, reducing the loss of the company's shutdown.
5. The quality of goods is stable and easy to be tested
The chemical composition of the commodity is stable and the particle grade is even, which is conducive to calcining.
The time of material staying in the vertical mill is only 2~3min, while in the ball mill, it takes 15~20min.
Therefore, the chemical composition and fineness of vertical mill products can be quickly determined and proofread.
6. Low wear and tear, high utilization rate.
Because there is no direct touch between the grinding roller and the grinding disc in the operation of coordinate grinding, the wear is small, and the metal consumption per unit commodity is usually 5~10g/t.
