Integrated Sample Preparation System
The integrated sample preparation system widely meets the relevant provisions of national standards such as GB/T 19494 Coal Mechanized Sampling, GB 474 Coal Sample Preparation Methods, GB/T 2007 General Rules for Bulk Mineral Sampling and Sample Preparation, etc., and is suitable for industrial quality control and analysis and testing links with strict requirements.
Features
- Full-automatic intelligent control: PLC programming and touch screen human-machine interface are adopted to realize one-key control of the whole process of sample making.
- Structural sealing design: fully enclosed working space, effective control of dust dispersion, in line with the requirements of modern environmental protection operations.
- Continuous belt feeding system: the material supply is uniform and stable, effectively avoiding particle size segregation and feeding blockage.
- High-efficiency crushing system: the first stage is hammer and knife type high-speed crushing, with strong shear and impact. The second stage is roll crushing structure with tooth surface treatment to ensure that the particle size is controlled within the target value.
- Modular reduction system: the reduction structure adopts the classic slot design, multi-stage series connection, flexible and adjustable reduction ratio, good sample representation.
- Anti-clogging and wear-resistant design: the use of stainless steel and alloy steel parts, effective resistance to corrosion, wear and high humidity sample clogging.
- Cleaning and iron removal function: built-in automatic cleaning mechanism and multiple iron removal devices to avoid cross-contamination and metal foreign body interference.
Main Advantages
- High efficiency: one-time completion of the entire sample making process, saving labor and time costs.
- Strong representativeness: high precision of reduction, sufficient mixing, effectively guarantee the quality of samples.
- No pollution: the equipment is fully enclosed, with automatic cleaning function, reduce human intervention, avoid sample loss.
- Convenient maintenance: modular structural design, quick disassembly of key parts, convenient for daily maintenance.
- High degree of automation: suitable for laboratory automation system or industrial field automatic sampling line, intelligent linkage.
Working Principle
The integrated sample preparation system continuously feeds the bulk material into the crushing area by belt conveyor, firstly, the hammer knife crushing system carries out primary crushing on the material to reach the preset particle size range. after that, it enters into the roller-type secondary crushing device to further refine to the target particle size, for example, less than 3mm, and the crushed material is then evenly mixed through the mixing device, and then enters into the shrinkage unit to carry out multi-stage shrinkage. In the process of reduction, the system automatically separates analytical samples, preparation samples and moisture samples according to the set ratio, and the discarded samples are discharged through the conveyor belt, and the process is fully automated without manual intervention.
