In order to achieve a continuous production capacity of 100 to 3000 tons\/hour and accurately control the fineness to 250-400 mesh, a customized vertical roller mill (VRM) or European mill must be configured. After 48 hours of continuous operation of many conventional equipment, due to the thermal expansion of the grinding ring and the wear of the powder separator, the output tends to plummet by 15% to 20%. And we have just overcome these 1 technical bottlenecks.<\/p>\n\n\n\n

The following technical guide combed in detail the specific equipment configuration scheme, our original “3-T” capacity evaluation model, and the 1 real operation data that actually reduced the tonnage energy consumption of mining enterprises by 22%. If you want to build a “zero downtime” production line, be sure to read the following disassembly analysis.<\/p>\n\n\n\n

<\/span>The Original Limestone “3-T” Capacity Configuration Model<\/span><\/h2>\n\n\n\n

When selecting a mining company, the owner must configure the equipment (I. e., the 3-T model) around 3 core dimensions: yield (Throughput), tolerance (Tolerance), and technology (Technology). If you only copy the basic parameter table provided by the manufacturer, system downtime will inevitably occur during peak production periods.<\/p>\n\n\n\n

Output (Throughput): 120 per cent of peak demand allowance<\/h3>\n\n\n\n

When designing the core mainframe, the engineer must reserve capacity at 120 percent of the daily maximum load. For example, if your target capacity is 200 tons\/hour, you have to choose equipment with a rated capacity of at least 240 tons\/hour. The hardness of materials mined from different mining areas often fluctuates, and this part of the surplus capacity can effectively prevent the motor from overheating and burning due to sudden load changes.<\/p>\n\n\n\n

Tolerance (Tolerance): Easily cope with 40mm large particles and moisture fluctuations<\/h3>\n\n\n\n

The front-end crushing link is difficult to always maintain a perfect 10mm feed standard. High-end limestone grinding systems are often equipped with heavy-duty grinding rollers that can directly eat raw ore up to 40mm. This high tolerance directly saves the trouble of three stages of crushing, not only greatly reduces the floor area of the plant, but also cuts off a large initial equipment investment.<\/p>\n\n\n\n

Technology (Technology): Direct Drive System and Variable Frequency (VFD) Separator<\/h3>\n\n\n\n

The old belt drive mill will lose up to 8% of its energy in mechanical friction alone. After upgrading the equipment to direct drive with planetary gearbox, 100% of the torque of the motor can be transmitted to the grinding disc. Coupled with the up-conversion (VFD) powder selector, the operator in the central control room can dynamically adjust the particle size of the finished powder at any time without stopping the machine.<\/p>\n\n\n\n

<\/span>Equipment Selection Guide: Vertical Roller Mill (VRM) Vs. European Mill<\/span><\/h2>\n\n\n\n

Choting the right host directly determines your operating cost (OPEX) in the next ten years. In large aggregate and desulfurization projects, the vertical roller mill (VRM) has absolute dominance because it integrates the four functions of crushing, drying, grinding and powder selection into a closed unit. The European version of the mill is more suitable for medium-sized, and high fineness requirements (such as up to 800 mesh) customers, its initial footprint is relatively small.<\/p>\n\n\n\n
