When sourcing an automatic small gold washing machine, buyers must first navigate a complex array of technical specifications that define the machine's capability and suitability for specific mining environments. The market offers a diverse range of models, often categorized by their primary function, such as the Diamond Washing Plant, rotary scrubber machine, or Trommel Screen. These variations are not merely cosmetic; they dictate the operational efficiency and the type of ore that can be processed. For instance, the "Small Gold Washing Machine" is frequently designed with a specific focus on gravity separation, distinguishing it from larger-scale industrial plants that may rely on chemical leaching or flotation.

A critical parameter to evaluate is the production capacity, which varies significantly across available units. Data indicates that capacities can range from 1 to 200 tons per hour, with some specialized models extending up to 800 tons per hour. This wide spectrum requires the buyer to align the machine's throughput with their actual mining volume. A unit rated for 100 tons per hour may be ideal for a medium-sized operation, whereas a smaller unit with a capacity of 1 to 800 tons per hour might be necessary for fluctuating ore grades or seasonal mining peaks. The feeding density is another vital technical constraint, typically observed in the range of 30% to 50%. Ensuring the machine can handle this density without clogging is essential for maintaining continuous operation.

Power consumption and voltage requirements are equally decisive factors. The electrical infrastructure of the mining site must be compatible with the machine's power needs. Available units often operate on a standard 380V voltage, with power ratings spanning from 15 to 55 kilowatts. This range suggests that while some models are designed for energy efficiency, others may require substantial power input to drive heavy-duty components like the rotary scrubber or the trommel screen. The rotation speed, observed at specific instances like 27.6 revolutions per minute, directly influences the separation efficiency. Buyers should verify that the rotation speed is adjustable or optimized for the specific particle size of their ore, which can range from 0-2mm to 0-6mm.

The physical dimensions and weight of the equipment are practical considerations for logistics and site installation. Some units are compact, with dimensions around 6 meters in length, 2 meters in width, and 2 meters in height, and weigh less than 1 ton, making them suitable for remote or mobile operations. Conversely, other heavy-duty models may weigh up to 2 tons. The material composition, often carbon steel with heat-resistant features, ensures durability in harsh mining conditions. The output size, which can be customized to specific requirements like 0-6mm or 0-2mm, must be matched to the downstream processing needs of the buyer.
