AROUND THE INDUSTRY PLANT and EQUIPMENT SOLUTIONS

Modular hoppers in demand

reports that both the grizzly feed hop- per’s performance and Pilot Crushtec International’s after-sales service have lived up to expectations. “We are very happy with the product and the atten- tion received from our supplier. The unit has already been earmarked for use in another assignment once its involvement in the Roma to Semonkong project has been completed.” Significantly, EXR Construction has now ordered its second Pilot Crushtec International product, a Pilot Modular Impact Crusher. The Pilot Modular GFH560 grizzly feed hopper is a heavy-duty machine ideal for quarrying and recycling operations and is particularly adept at removing fines or oversize rock and ore from feed material before further processing. It is also well suited for standalone operations, exam- ples being the scalping and screening of coal, aggregate, sand, construction and demolition waste, mine ore blasted rock and river gravel. The GFH560 grizzly feed hopper comes standard with a heavy duty 50 mm diameter grizzly bar with an 100 mm aperture and is compatible with the com- pany’s entire range of crushing, screening and washing equipment. Mounted on a heavy-duty skid frame, the hopper is easy to transport and install while strategically positioned inspection doors and grease points ensure in-built reliability and ease of maintenance. www.pilotcrushtec.com

of the mineral processing industry. An e x amp l e o f J o e s t ’s ‘Engineered Solutions’ approach is its design and development of a 4,3 m wide banana screen to cater for the ongoing trend in the coal processing sector to opt for larger equipment so as to increase throughput and boost efficien- cies. “We have paid close attention to our clients’ needs by assessing the failure modes of existing 4,3 m wide screens from other suppliers in this market, and designed our screen with the focus on reduced downtime and ease of maintenance when required,” Alston says. “There are 50 to 60 screens of this size in the coal processing sector at pres- ent, many of which are approaching prior to screening automatically cre- ates efficiencies by balancing the plant’s operation. This balance facilitates a steady flow of feed which permits plant compo- nents – crushers, conveyors and screens, to operate at their design efficiencies. “The balancing effect derived by these efficiencies also means that a product like the Pilot Modular GFH560 saves wear on working surfaces, bringing about a saving in maintenance costs not to mention that of power, which is especially significant in an operation working 24/7.”  He adds that Pilot Crushtec International’s ability to offer a rapid response to customer needs, as was the case with EXR Construction, has had a major influence on sales. “EXR Construction is engaged in a R680-million project for the building of a road between Roma and Semonkong, and needed to replace an existing feed hopper. The urgency arose from the fact that some 40 km of the road was to be constructed at an altitude in excess of 2 200 m and work had to be completed before the onset of winter snowfall.” Following recommendations from onsite contractors with previous expe- rience of Pilot Crushtec International products and a visit to its Jet Park head- quarters, an order was placed and the GFH560 was immediately shipped from stock direct to its destination in Lesotho.

Customised screens Screens from specialist vibrating equip- ment manufacturer and supplier Joest, are customised to match the metallurgical requirements of a client’s process and the associated mechanical duty. Joest brands this benchmark its ‘Engineered Solutions’ approach to supplying its clients with a total solution. “Our customised screens are often the preferred equipment due to the robust design and proven performance,” says Derrick Alston, Joest CEO. “Understanding the difference in design and duty for pro- cess plant screens, particularly sizing feed preparation in washing and Dense Media Separation (DMS) applications, is a key fea- ture of our ongoing success in other sectors sales manager Nicolan Govender explains that the hopper’s compatibility and ease of integration with both his own com- pany’s crushing and screening products as well as those of other manufacturers means that the GFH560 is fast becom- ing the feed hopper of choice. “Current economic conditions dictate that mining and quarrying operations need to maxi- mise the efficiency of workflows and in the crushing and screening industry, an efficient feed hopper is a prerequisite to achieving this goal.” Govender explains that the installa- tion of a feed hopper between primary and secondary crushers or immediately A recent delivery of a Pilot Modular GFH560 grizzly feed hopper for use by EXR Construction in a Lesotho roads pro­ ject, heralds the fact that close to 200 of these rugged units are in active service across the African continent.
