Modular Wash Plant

Modular wash plant as a representative equipment that combines multiple washing, coarse and fine materials concentrated dewatering, fine sand recycling and other functions in one equipment. It is applicable to sand and gravel plants, construction sites, hydropower dams, glass manufacturing, oil well development and other industries. Compared with the washing and recycling machine, it has been greatly improved in performance.

How modular wash plant work?

The qualified materials after classified by screening equipment flows into the screw sand washer through chute or pipeline. Sand and gravel are fully separated from impurities and mud through the fully cleaned, soaked and broken by screw mixer. Fine sand and muddy water are deposited in the tail of sand screw, and the fine sand is recovered through cyclone separator. Then the coarse and fine sand enters wheel sand washer machine at the same time for secondary cleaning to achieve complete separation of sediment. The coarse sand is lifted onto the high frequency dewatering sieve by impeller of wheel sand washer, the overflow muddy water flows into the dewatering screen water tank and concentrated by cyclone separator, and is dehydrated by the vibration of screen to finally realize the cleaning, recovery, dehydration and dry heap discharge of gravel.

Popular Applications

A Sand Dewatering Screen can be supplied as part of a sand separation system or added later as a final dewatering step.

Features

1. Energy energy saving and environmental protection are the major themes of multi-functional sand washers. Functions include sand washing, fine sand recovery, dehydration and de-sludge, concentration and classification, which can effectively remove sand impurities and obtain high quality sandstone proucts with clean and low water content.
2. Multiple functions, reasonable structure, easy operation.

Frequently Asked Questions

How will the Sand Dewatering Screen save me money?

A Sand Dewatering Screen can save you money in several ways. Sand that is drier and cleaner requires less conditioning, which means less loader and operator time. Less conditioning means smaller stockpiles of sand.

What size screen should I consider?

Screens work best when a bed of sand can build up during the dewatering process. If the sand bed is too big, it will eventually build up and plug the screen. If the sand bed is too small, a larger percentage of fines will escape with the water. Each screen is sized for the specific application into which it will be installed.

How do we know that the sand is cleaner and drier?

The first dewatering screen used for recycled sand underwent extensive testing and sampling.

How does this work with a Sand Lane System?

There are several ways to configure a Sand Lane System, but basically it involves cleaning the sand from the lane and dumping it into a hopper, which feeds the dewatering system.

Can I add water to the Sand Dewatering Screen to make my sand even cleaner?

Sometimes the sand is still dirty when it enters the Sand Dewatering Screen. If the manure fibers are larger than the screen openings, then they cannot be washed out. In some cases, though, it’s possible to install a spray bar and add some clean water to rinse out the dirty manure water. When doing this, it’s important to install a weir partway up the deck to create a break in the sand bed through which the water can go. McLanahan's engineering team will be able to help with setting up a rinse bar on your screen.
