Concrete

Remove the need for pits

Most concrete plants are located in urban areas where space is a premium and contamination is unacceptable. Returned concrete from site and truck washout is very difficult to handle and takes up a lot of space. The average plant has 4 to 6 wedge settling pits as well as a slurry stirring pit and recovered water pit.

All of this is money, space and many unnecessary truck and loader movements to handle the concrete waste. In the end waste material can take weeks to dry out enough for transport. Even then you are transporting a significant quantity of water with the waste material. 

Eliminate your wedge settling pits by investing in one 4m x 1m elevated concrete filter press. Recover clean water for re-use immediately and produce small, transportable dry concrete filter cakes.

Reduce the number of vehicle movements

Aggregate B double semi trailers  dropping off feed material, front end loaders filling feed hoppers and pushing up stockpiles, concrete trucks washing out and dumping returns.  All of these movements are part of the business of producing revenue. The more efficient this process the lower the cost and the lower the risk. 

Adding traffic movements  to rotate wet concrete and semi dry concrete from ponds to holding bunds and then drying bays adds time, cost and risk. Additional bunding and drainage is also required to manage waste and runoff. 

Eliminate unnecessary vehicle movements and the costs associated with this by replacing the traditional concrete recovery pits with a single concrete filter press.  This single closed loop system processes the cementitious slurry through an automated filter press delivering clean water back to the plant and dry, transportable concrete cakes in a skip bin .

Reclaim water for reuse

Concrete plants require significant clean water to produce quality concrete. In some urban areas there may be considerable concern from locals about the use of town water for industrial operations. Disposal of contaminated water and runoff into natural waterway is also a contentious issue some operators are forced to deal with.

Recovery of water for re use is a challenge most industrial processors are faced with when considering expansion of their facilities. Whilst many concrete plants use wedge pits to recover water from concrete washout systems it is extremely inefficient and can sometimes be seen by locals as water wast rather than water recovery. Waste concrete is often removed as a wet waste which is not only very costly but it also disposes of water that could be otherwise used in the concrete plant.

Eliminate settling pits and maximise recovery of clean re-usable water by installing a single concrete filter Press. The automated filter press will maximise recovery of clean water and will produce a dry concrete cake which can be immediately transported as dry waste.

Free up valuable real estate

By their nature, concrete plants are typically situated close to the location of end use. Which, in the case of infrastructure and large scale building operations is often in highly urbanised areas. The value of real estate is high and the pressure from environmental and neighbouring interests is also high. Many concrete plants use valuable real estate for handling waste concrete and for recovering water. Of course this is an extremely ineffective use of land and can seriously limit the capacity of the plant operation.

Replacing slurry and waste waste pits with a single concrete filter press every concrete plant can eliminate the impediment to growth and maximise the productive use of the land that the plant is sitting on.

This close loop system requires only the stiring pit for the cementitious slurry and the clean water pit. All other wedge pits, ponds and retaining bays can be freed up for productive use.

The McLanahan Filter press captures all cementitious concrete and turns it into dry concrete cakes immediately ready for transport whilst maximising recovery of clean re usable water.

McLanahan concrete recovery systems and concrete filter presses help producers effectively deal with concrete washout by turning it into transportable dry fines and clear water. Solids material such as sand and aggregate can be recovered for re use. Cementitious slurry is captured and delivered into two streams: Clear water and dry filter cakes. The McLanahan Tiger Press is recognised around the world as the most effective filter press and the only press specifically designed for capturing cementitious slurry.

Testimonials

Great work is only possible through great clients. We thank our clients for allowing us to work on streamlining their business through smart processing solutions.

Ready Made Concrete

“Once we understood how it worked, the use, and that they had put these presses in in the past, that intrigued me as well because we were having an issue with water and contamination and trying to reuse water,” said Philips. “It was a small footprint and so we thought it would fit within the area that we had designed for our reclaiming system.”

Stevens Creek Quarry

“It was such a problem being down for seven or eight days while the pond was being maintained,” said Jason Voss. “That and the costs of it made it a real issue for us – one that wasn’t going to go away if we didn’t find a solution.”
