The drum stone washing machine adopts the principle of friction between machinery and stone to clean the raw stone, which ensures enough productivity to meet the supply of stone while ensuring the quality requirements of the project.
The working process of the drum stone washing machine is generally as follows: raw material storage, transportation, cleaning, transportation of finished materials, sewage precipitation and reuse.
The drum stone washing machine can process materials in the range of 50-200mm, and can wash the soil and ash powder on the materials into clean materials. It is commonly used in the washing of manganese ore, iron ore, limestone, tungsten ore, tin ore, silica sand and other minerals. The drum washing machine has a large processing capacity and is an ideal equipment for enterprises with large production capacity and requirements.
When the drum stone washing machine is working, the cleaning cylinder is supported by the tug frame, the motor drives the reducer, and the large and small gears drive the cleaning cylinder to rotate at a low speed. The aggregate containing mud and stone powder is fed from the feeding port into the rotating drum, and the wear-resistant lining plate installed with a certain angle in the cleaned drum is continuously lifted and dropped, and moves from the feeding end to the discharging end. During the process, it is circulated for many times and washed by flushing water in the forward or reverse direction. The cleaned aggregate is screened and dehydrated by the discharge end drum screen and discharged. Wastewater containing sludge flows out through a perforated baffle at the discharge or feed end.
The drum stone washing machine is used for the desliming operation of artificial sand and stone less than 200mm aggregate. It has the advantages of large feed particle size, mud content of aggregate can be less than 0.5% and water content is less than 2% after washing
The cleaning capacity of two drum stone washing machines working together is stronger, and the mud content after washing is generally not more than 0.4%, which is better than the relevant standards. After washing, because the gravel is clean, the strength of concrete is uniform and stable, under the condition of constant
strength, the amount of cement can be saved about 5%.
