實驗室用洗礦機是黑色、有色、冶金、礦山用來清洗礦石的實驗設備。將該設備中加入清水，通過攪拌,清除原礦中溶于水的泥砂等雜質，使礦石達到工藝要求，取得實驗數據。本洗礦機適用于清洗 15mm以下的礦石，以清洗錳礦石為例，設錳礦石含泥量＞30%，經洗礦機清洗后.含泥量為 15%，使礦石達到工藝要求和經濟指標。

Ore washers in laboratories are experimental equipment used to wash ores in sectors such as ferrous metal, nonferrous metal, metallurgy, and mining. The washing process is: Add clean water to this equipment and remove the impurities dissolved in the water such as mud and sand in the raw ores by stirring them first, so that the ores can meet technological requirements. Such spiral washers are suitable to be used to wash ores with the size of below 15mm. Take manganese ore for example, if the silt content of manganese ore is ﹥30%, this figure can become 15% after they are washed by such ore washer so that the ores can meet technological requirements and hit the economic target.
