Water-Saving Sand Washing Plant

Choosing water-saving equipment and integrating recycling functions is the key to fundamentally reducing water consumption.

Select advanced sand washing equipment

Bucket-type sand washing machine: The structure is simple, with almost no wearables except for the screen, and the failure rate is low. It adopts a circulating water cleaning method and is one of the relatively more water-efficient mainstream choices currently.

Integrated sand washing equipment: This type of equipment integrates sand washing, fine sand recycling, dehydration, and even wastewater treatment functions into one, significantly simplifying the process flow. For example, some new equipment uses built-in bubble flushing technology to improve the flushing effect and avoid secondary cleaning waste caused by incomplete cleaning.

Mandatory water recycling system

Modern sand washing equipment usually comes with a water recycling system, which can collect, filter, and reuse water during the cleaning cycle. This approach can minimize fresh water consumption, while reducing emissions and environmental impact. For instance, some patented technologies use multiple water collection tanks and filtration pumps to filter and recycle water from the overflow of the sand washing pool and the water carried out by the spiral blades, significantly enhancing water-saving performance.

Chromite purification processing method

At present, chromium ores with industrial value are generally chromium-magnesia spinel or chromium-iron spinel minerals, which contain a large amount of chromium oxide, with a content of about 18% to 62%, and generally also contain metals such as aluminum and nickel. Its characteristics make the chromium ore beneficiation process present a rich and diverse state. Due to the properties of chromium, chromium ore beneficiation processes include gravity separation, magnetic separation, flotation, combined beneficiation, chemical beneficiation, etc. Commonly used in industry are single gravity separation, single magnetic separation, and gravity-magnetic combined beneficiation processes. In terms of equipment selection, shakers and jigs are mostly used in the gravity separation stage, while the equipment selection in the magnetic separation stage is determined based on the magnetism of the ore.

The classifications of quartz sand

1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
