CDE Sand Washing Plant improves product quality and produces plaster sand
Following the installation of a CDE Dual Sand Washing Plant on their sister company's site Analiza, South African brick and block manufacturer Multi Crete Bricks "just can't keep up with orders", according to its CEO Christo Niemand.
Multi Crete, a Brakpan-based company, has been supplying the South African construction industry for 16 years, delivering premier quality brick and block products nationwide as well as supplying customers directly at their Brakpan factory. The company not only ensures that the best raw materials are selected but also guarantees the best end-product by overseeing production from start to finish.
In 2016, Multi Crete saw an opportunity to upgrade their sand screw washing plant to remedy the substantial loss of valuable fines that was ending up in its quarry's dam and take the lead in the local materials washing market. The company continues to produce its own bricks, blocks, and manufactured washed sands and has just added plaster sand to its offering, which the new CDE dual sand plant on the Analiza site has made possible.
A direct approach for a better solution
Christo Niemand is a savvy and practical businessman, who relies on a combination of word of mouth and direct contact with experts who can demonstrate the value of their equipment in a ‘seeing is believing' manner. In this spirit, the Multi Crete CEO, who manages 16 employees, as well as quarry staff, visited a close-by quarry with a CDE representative to witness the efficiency of the CDE materials washing equipment in action.
Convinced by the high tech but user-friendly aspect of CDE installations, Mr Niemand took the next step and challenged Nicolan Govender, CDE Regional Manager for Africa, to find the best-value-for-money washing solution that would significantly reduce the amount of lost fines, increase production levels and sand quality, and crucially allow for multiple sands to be manufactured at the same time, therefore, boosting offer and subsequently, demand. The CDE dual sand washing plant ticked all of these boxes and Christo Niemand says that he is now ready to upgrade his equipment even more to meet the ever increasing demand for Multi Crete products.
Mr Niemand reflects, "The combination of a solid relationship with our local CDE experts and the commissioning of an ultra-performant sand plant has given Multi Crete's activities a positive boost. Our plaster sand is hands-down the best in the region and being able to produce two products at the same time, including plaster sand, is truly remarkable."
The Analiza quarry treats raw materials including crushed rocks, a mixture of granite, silica, some being heavily clay-bound. It now produces 23 tonnes per hour of plaster sand and 19 tonnes per hour of river sand. The sand plant allows for two products to be produced at the same time and can also be set to alter the amount of finer sand in the end-product, allowing the client to produce two off plus zero products (- 2mm + 0 and - 6 mm + 0).
Mr Niemand continues, "Our return on investment is good and we are already looking towards the future and to expand our range of products. We are considering adding complementary CDE equipment to our installation when we have addressed the issue of limited power and water supply."
Wayne Warren, CDE Business Development Manager for Sub-Saharan Africa, looks back on a successful relationship with Multi Crete, based on regular meetings with Mr Niemand and visits to the Multi Crete factory and the Analiza site, says, "Being based in South Africa means that I am only just a phone call or a short trip away from my customers.
I have the opportunity to visit Mr Niemand and check on the CDE sand plant at Analiza regularly. It allows me to iron out any arising issues and keep the conversation going on how CDE can help to reach new performance requirements quickly and efficiently.
It is very gratifying to witness the steady performance of a piece of equipment year after year. Multi Crete has become one of the best-performing sand washing operators in South Africa due to the upgrading of their installation to the CDE cyclone technology.
It just makes business sense to improve plants that waste fines and water and ultimately affect the company's performance and ability to compete in a growing market. Multi Crete is a proof that adopting our cyclone water-saving technology works", Warren continues.
Mr Niemand concludes, "Swapping the Analiza sand screw classifier for a CDE dual sand plant has turned out to be an excellent investment. We are saving water and time whilst increasing and diversifying materials production. We are now able to position ourselves on the local market as the leading suppliers of construction materials.
"As a bonus, we have been able to commit to safer operations as CDE equipment have both high tech systems and are simple to use, with well-conceived safety details that guarantee a comfortable working environment."
