New single-stage hammer
crusher in cement plants
Technical Transformation
- Sand and gravel aggregate production capacity growth rate ≥ 15%
- Proportion of aggregates ≤ 50mm ≥ 90%
One Machine for Dual Uses
- It can either crush limestone purely or produce aggregates, realizing two functions in one machine.
- No need to build a new aggregate production line. By directly adding a screening module and a storage & shipment module to the original crushing station, the industrial chain can be extended, effectively reducing investment.
New Aggregate Line
- Low investment: The comprehensive investment in the limestone sand and gravel aggregate production line is reduced by approximately 40%.
- Small floor area: The short-process production line covers an area of about 20-50 mu.
- Low energy consumption: Compared with production lines using other processes, the energy consumption of the short-process production line can be reduced by approximately 45%.
- Controllable fine powder content: Fewer crushing links avoid over-crushing, and the 0-5mm fraction is reduced by more than 5% compared with other processes.
- Excellent particle shape: The content of needle-shaped and flaky aggregates does not exceed 2%, and the particles are multi-angular and cubic.
Technical Transformation Advantage Analysis
- Increased output: After technical transformation, the output can be increased by 50%, fully meeting the increased limestone demand brought by the cement plant’s technical transformation process.
- Reduced unit energy consumption for crushing: The energy consumption of the adjusted crushing equipment will be lower, saving energy and electricity by more than 50% compared with similar products.
- Significantly reduced particle size: After the transformation, the particle size is greatly reduced from 70mm to below 45mm, which is conducive to giving full play to the working performance of the raw meal mill.
- Significantly reduced energy consumption of the cement system: The production efficiency of the mill is greatly improved, which can shorten the startup and operation time. At the same time, the startup time can be adjusted to the off-peak power period.
Technical Transformation Comparison
- Technical transformation time: < 10 days
- Average output: 1200 t/h; Peak output: 1300 t/h
- Electricity consumption per ton: Reduced from 1.43 kWh to 0.77 kWh, a decrease of 45%.
- Discharge: Screen residue test shows that the proportion of discharge particle size below 50mm is 95%, with an average discharge particle size of 24.5mm.
- Hammer quantity: Reduced from 50 pieces to 16 pieces.
- Unit wear: Reduced from 18 g/t to 7.04 g/t.
