The following is a detailed description of the production line configuration plan and key points for limestone crushing, with an output of 200 tons per hour and capable of simultaneously producing 05 (0-5mm), 51 (5-10mm), 12 (10-20mm), and 13 (16-31.5mm) specifications:
I. Core equipment configuration plan
Fixed production line (high cost performance)
Coarse crushing stage:
Core equipment: Heavy hammer crusher, such as PCZ1308 or PCZ1512 models. These equipments are known for their powerful crushing capacity and high crushing efficiency. They can directly crush limestone with a particle size of ≤650mm to ≤30mm at one time, laying a solid foundation for the subsequent medium and fine crushing and sand making links.
Advantage: Reduces the number of material transfers, reduces production costs, and improves the overall efficiency of the production line.
Medium and fine crushing and sand making stage:
Matching plan 1: Impact crusher or double rotor sand making machine, such as ZSJ1215 model. This type of equipment is good at handling medium and fine crushing tasks, and can easily produce finished products that meet the specifications of 12, 13 gravel and 05 machine-made sand.
Matching solution 2: "Cone crusher + sand making machine" combination. When the raw material hardness is high or the particle size varies greatly, this combination can show stronger adaptability and crushing efficiency, ensuring the stable operation of the production line.
Screening stage:
Core equipment: Multi-layer vibrating screen, such as 3YK2060×2 or 4YK2460 models. These vibrating screens have the characteristics of high precision and high efficiency, and can accurately separate stones of different particle sizes to ensure the quality of finished products of various specifications.
Mobile production line (flexible and efficient)
Combination solution:
Crawler mobile jaw crusher: such as CJ96 model, is responsible for coarse crushing tasks, and can quickly crush large pieces of limestone to smaller particle sizes.
Mobile impact crusher: such as CI1316 model, is responsible for medium and fine crushing tasks, and further refines the material particle size.
Mobile sand making machine: such as the HVI0926 model, which is responsible for sand making tasks and can produce high-quality 05 machine-made sand.
Or a single multi-stage crushing mobile station: such as a cone crusher + screening machine, this equipment integrates crushing and screening, is more compact and efficient, and is suitable for occasions with high site requirements.
Advantages:
Mobile production lines do not require infrastructure construction and can be directly stationed in the mining area for operation, greatly shortening the construction period and reducing investment costs. At the same time, it is convenient to change sites and can flexibly adjust the operating position according to production needs.
2. Key designs for limestone adaptation
Energy saving and consumption reduction
Hammer crusher "one-time forming" technology: By optimizing the hammer head structure and crushing chamber design, limestone is crushed in one forming, reducing energy consumption by about 30%. The application of this technology not only improves production efficiency, but also reduces energy consumption and environmental pollution.
Grain shape control
Impact crusher or sand making machine: These devices can produce strong impact and shearing effects during the crushing process, making the crushed stone have a high cube rate and less needle-like flakes. By adjusting the speed of the impact plate or sand making machine, the feed particle size and other parameters, the particle size distribution and shape of the finished product can be further controlled.
Environmental protection measures
Closed crushing system: The entire crushing process is carried out in a closed environment, which effectively reduces dust leakage and noise pollution.
Dry dust removal system: Advanced dry dust removal technology is used to efficiently capture and treat the dust generated during the crushing process to ensure that the dust emission concentration is ≤20mg/m³, which meets national environmental protection standards.
Automation control
PLC control system: The PLC control system realizes the automatic operation and real-time monitoring of the production line. The system can automatically adjust the feed rate, crusher speed, screening frequency and other parameters according to production needs to ensure the stable operation and efficient output of the production line. At the same time, the system also has fault alarm and remote diagnosis functions, which is convenient for operators to find and deal with potential problems in time.
