Sandwashing plant

 

Allgaier Mogensen S.A.U has been manufacturing hydrocylone mineral washing machines for more than 20 years and offer its clients joint experience, both for the traditional applications of this machine (washing different minerals, washing sand used in building materials and other industrial uses, treating bentonite sludge, etc.) and for new applications such as manufacturing sand for top-quality concrete, automatic restructuring of sand grain size curves or treating contaminated soil.

As far as this type of applications is concerned, the output and efficiency of these machines are much higher than washer wheels or worm gear. Top-quality sand is always achieved due to a higher friction capacity between particles and no loss of fine sand.

Working principle
 
Sandwashing machines are designed to obtain sand that meet industry requirements such as grain size, fineness or cleaning harmful materials (clay, organic matter, chloride, sulphates, etc.).
The operating method of this type of machine can be summed up as follows:
Water pulp plus contaminated sand fed to a tank.
Pumping stage from main tank to cyclone.
Pulp cycloning stage (separation of sand and clay or filler).
Water and clay from cyclone enter secondary tank for automatic adjustment of main tank level using buoy system.
Clean sand from cyclone drained.
Water and clay or filler leave secondary vat to go to thickening process.
Washed sand leaves for storage via channel.
Depending on the process and operating conditions (percentage of material to be removed and the end product quality required), a series of several cycloning stages may be necessary.

Range
 
The component of each unit, i.e. pumps, motors, drainers, hydrocyclones, etc. will be selected in accordance with the job specifications. The wide variety of combinations available allows a broad range of practically tailor-made machines to be manufactured for each client, thus optimising the investment necessary to produce the facility.
The range of products goes from 20 T/h of sand washed in the smallest machine up to 300 T/h in larger versions.
Due to the abrasive nature of the materials to be processed and demanding operating conditions, as a standard highly resistant materials, components and linings are selected. Based on an individual study of each product, special solutions are sought for even the strictest requirements. The choice of pump is extremely important. Here, factors such as the abrasiveness and grain size of the material and the concentration of the pulp to be pumped require a special study of the type, speed and linings of the pump.
