Setting new performance standards in Phalaborwa

There are hardly many mining sites in the world where you can see herds of elephants and buffalo roaming about. At the mining complex in Phalaborwa, right next to the mighty Kruger National Park in the northeast corner of South Africa, that sight is commonplace.

The vast Phalaborwa complex is host to several valuable minerals such as phosphate, copper, zirconium, iron, and vermiculite. Phosphate is a key mineral in fertilizers. Before the foundation of the Phalaborwa mine in 1951, the South African agriculture was dependent on imported phosphate rock. Today, South Africa exports phosphate fertilizers around the world.

Venter Drilling, a local family business, has been the drilling contractor at the site for some ten years. In early 2018 they were contacted by Robit SA with a proposal to test Robit’s DTH bits and hammers. Not being completely satisfied with the products of their then supplier, the owner of Venter Drilling, Pieter Venter, agreed to have a testing programme arranged. This was a win-win deal, as it would also provide Robit with genuine feedback on their products.

The first test run involved ten DTH bits and a DTH hammer. “On the outset we wanted to achieve 800 metres per bit and 8,000 metres per hammer”, says Len Botha, who does business development for Robit SA. “In the initial test, the hammer reached 10,767 metres. The bits reached an average of 1,198 metres, with the best one drilling down to 1,699 metres. The previous supplier had averaged only 811 metres per bit”, Len recounts.

This was, of course, extremely promising, but to thoroughly convince Pieter Venter, another set of tests was arranged. This time the hammer went on to do over 12,000 metres. The bit performance was consistent with the first tests.

“Robit tools managed to reduce the overall bit cost by 32 %. This was mainly due to the DTA type of design that we introduced: 18 mm buttons on the peripheral and 16 mm on the inside, with the three centre flushing holes”, says Len.

Phalaborwa holds reserves of some 2.5 billion tonnes of phosphate rock, or five percent of known world reserves. That means the elephants and buffalo will be continuing their friendly co-existence with the miners for quite some time in the future.

Taking ground in the Brazilian quarry market

Concrete is the most versatile and most widely used material for construction. In a typical concrete mix, as much as 60% to 80% of it consists of aggregates. Aggregates for the construction industry are the most consumed mineral inputs in the world – including Brazil.

“In Brazil, extracting aggregates is a key activity in the mining sector. The recent economically lean years saw a reduction in production volume, but the economy is now recovering step by step. This applies to the aggregates market as well – and Robit found an important partner to help advance our growth strategy in the country”, says Alexei Albuquerque, Distributor Business Manager for Robit in Latin America.

Paraná Drill was founded in 2001 to serve the quarry market with equipment, parts and consumables. Based in Curitiba, the capital of Paraná state, the company covers the south states of Brazil.

“I’m always looking for quality products with a good reputation. Knowing that Robit was searching for a new distributor for this market, I approached them Taking ground in the Brazilian quarry market and introduced Paraná Drill and our operation in the segment”, says Fabiano Buffon, the President of Paraná Drill.

“We then organized a test in our quarry to learn how Robit’s tools would perform. I had a really good first impression of them and the results were positive, as we’d expected. We are happy with the performance of Robit’s tools and the support their team provides”. Today Paraná Drill is a recognized company in the quarry market, especially in southern Brazil. The market has great growth potential but also faces challenges.

“In addition to contending with our competitors, we need to deal with import duties, long-term customer financing and great variation in exchange rates. Having a partner with cost-effective high-quality products certainly helps”, Fabiano Buffon concludes.

Marina gets overhaul in Britanny

In the late 18th century, France’s revolutionary government was in its prime. Napoleon’s star was rising and his armies swept through Europe. Napoleon himself knew that “armies march on their stomachs”. The government offered a 12,000-franc prize for the invention of a method of preserving food during long military campaigns. This would later have far-reaching impacts on the small Brittany village of Quiberon.

After years of experimentation, Parisian confectioner Nicolas Appert discovered that the combination of heat and air-tight packaging prevents food from getting spoiled. And so canning was invented – and Appert pocketed a nice sum of 12,000 francs.

Not long after, it was discovered in Brittany that tin cans were also a convenient way of preserving sardines. In the 19th century, Quiberon became the leading harbour for sardine fishing and the production of canned sardines in France.

Quiberon’s canned sardines can still be bought today, even online, but sardine fishing as a livelihood gave way to tourism a long time ago. Nowadays, the charming Port Haliguen is an important marina for recreational boaters, with more than 1,100 moorings and 11,000 overnight stays a year. Next to the marina lies a long stretch of beautiful sandy beach.

Originally built for fishing boats, the port was being stretched to its limit in terms of growth. The port’s infrastructure and installations are past their prime, and natural silting has made the harbour basins too low for larger boats.

A massive renovation project is currently under way in Port Haliguen: Its two harbour basins are being dredged deeper, the quays and pontoons are being completely redesigned, and additional moorings will be installed. In the first phase, the goal is to remove more than 50,000 cubic metres of clay from the basins. The clay will be used as filler in a new parking area that is to be built.

The contractors on the project are VINCI Construction Maritime et Fluvial and Eiffage TMF. The harbour foundations are constructed as a combi-wall structure, where steel piles are drilled into the seabed as load-bearing structures and steel sheets are installed in between them to form a wall. Robit was in charge of the technical solutions for the combi wall, under the leadership of Senior Specialist Kari Juntunen and Distributor Business Manager Taha Laissaoui. “Together with VINCI, we came up with the best overall solution, including equipment and operating methods. And it proved to be a winner: the piling was a great success,” recounts Taha.

A total of 460 piles with an average length of 15–18 metres were drilled. Some of the piles were delivered by the Finnish company SSAB. Robit’s delivery included casing systems (DTH-ROX SR 863/23), a robust 24-inch hammer and shock absorbers.

The port modernisation project is massive, and for the time being, the screeching of the seagulls is drowned out by the rumbling of excavators and drills. Port Haliguen should be ready to welcome travellers in all its renewed splendour in 2020.
