CONVEYOR MAINTENANCE SERVICES
DGC AFRICA offers comprehensive installation and conveyor maintenance services to all our customers. An integral part of our conveyor belt maintenance service is carrying out inspections and making recommendations for preventative maintenance measures that help minimize the risk of breakdowns.
We offer conveyer belt service packages to ensure that you optimize the working time of your conveyors so that your production can run non-stop if necessary. In this way, we can help you to achieve the best possible operational lifetime out of your conveyor belts.
INSPECTIONS & DIAGNOSTICS
As part of the conveyor belt maintenance service, we will carry out inspections and make recommendations for preventative maintenance to help minimize the risk of further breakdowns.
To ensure continuous monitoring of your belt and on-spot damage detection, we can provide you with belt diagnostics systems. Thanks to this new technology, the system will detect a problem before it becomes serious. In this way, a small timely repair can help to avoid a much bigger repair or even the loss of an entire conveyor belt and all of the costs associated with a major stoppage.
CONVEYOR BELT SPLICING
DGC AFRICA provides conveyor belt splicing services. Conveyor belt splicing is a cost-effective solution for all mining sectors, aiming to keep conveyors running smoothly. Our conveyor belt splicing process accelerates the mining industry with a solution for breakdowns of conveyor belts, as well as repairs. Our aim is to provide you with a stable belt splicing, making it ideal for moving various materials across the conveyor. Furthermore, we do quality control checks on all essential components.
Conveyor belt splicing is the process of joining two pieces of a conveyor belt. Usually, this is done to either elongate the original conveyor belt or to repair a torn or damaged one. Conveyor systems are employed in various industries, meaning that there are many types of conveyor belts and components.
To properly splice a belt, we ensure that the type of belt, speed of conveyor belt system, materials traveling on the belt, and conveyor belt environment are considered. If a splice is not done properly, the integrity of the belt, and the entire conveyor system are compromised.
HOT & COLD SPLICING
Conveyor belt repairs can take operations offline for a substantial period. DGC AFRICA utilizes hot and cold splicing methods to repair a conveyor belt to a high-quality standard and also ensure that you are up and running as quickly as possible with the best solution.
Cold splicing can be used for most conveyor belt applications and can be a good solution for low tension operations that do not convey hot materials. Cold splicing uses a bonding agent that causes a chemical reaction which ensures that cross-connections between different monomer chains are created to splice the two ends of the belt together.
Hot splicing uses extreme heat and pressure to bond the ends together. Once the materials have cooled down, the joint will be a smooth, seamless, and long-lasting splice. We can do this process both on and off-site by using a mobile vulcanizing press. In short, we will make every effort to make your splice joints as strong and as durable as possible.
Hot and cold splicing of belts requires meticulous preparation to prevent contamination of the splicing area. Cold splicing requires relatively warm conditions and low moisture to ensure the cold vulcanizing cements work optimally.
Quality Compounds - We make use of only the highest quality compounds used for splicing. Additionally, we offer optional heat resistance, fire resistance for belting, oil resistance, and graded covers.
Standards - Every job is thoroughly inspected before and after splicing takes place. Our skilled team of technicians provides the best turn-key solutions, moving you forward with the best quality solution. Each platen is checked for stability and temperature. Thermostat checks are done as an additional safety measure, along with calibration on hydraulic pump gauges.

CONVEYOR BELT PULLEYS
DGC AFRICA supplies high-quality conveyor pulleys which include, Tail Pulleys, Snub pulleys, Single and Dual drive pulleys, Head pulleys, Spiral pulleys, Grease filled pulleys, Oil-filled pulleys, T top pulleys, and Bar or Slatted pulleys. Our pulleys are manufactured in accordance with the SANS 1669 standards.
Our company also specializes in the repair and refurbishing of conveyor pulleys. Worn or damaged conveyor pulleys can be collected from the mine, thoroughly inspected by our engineers, and repairs quoted on accordingly. We do find that having conveyor pulleys repaired, as opposed to ordering new pulleys, could lower costs as much as 50%, and drastically reduce the turnaround time. Our customers can specify if you would like to have the pulley fitted with rubber lagging or ceramic lagging, as is fit for purpose, inclusive of choosing a bearing brand to be fitted, which is conducive to the relevant application. All conveyor pulleys that are repaired come with a one-year manufacturing default warranty as a service standard.
CONVEYOR BELT IDLERS
DGC AFRICA supplies a wide range of Conveyor Belt Idlers as well as idler rolls, frames, stools, and stringers (H frames), in accordance with the SANS 1313 specifications. A unique component is our nylon-bearing housing. The benefits of the Nylon bearing housing would be the reduction in roller weight, a reduction in operating noise levels, non-corrosive, lower operating temperatures, reduction in bearing friction, ultra-strong and durable but besides all these unique qualities, the best feature would have to be the fact that the Nylon bearing housing has a stone guard, which makes our rollers anti seas in high spillage areas. Our Nylon bearing housing is in two parts, there is an inner part that is hydraulically pressed into the SANS steel pipe, then an outer portion with a triple lip dust seal fits over the inner and onto the rollers shaft. When the roller spins, the outer part of the bearing housing remains stationary, thus making it impossible for the roller to cease with material jamming in between the roller and frame.
Our Conveyor Belt Idlers are manufactured in accordance with SANS 25 and 30 series rollers, in 127mm diameter, 152mm diameter as well as 101mm diameter and including any special client requests for non-standard rollers. All our rollers are manufactured using a SANS-approved steel pipe, the bearings used are high-quality 6205 which are sealed and greased for life with a C3 clearance. All steel rollers are coated with Red Oxide paint, to minimize corrosion.
Idler rollers manufacture:
Troughing rollers (Steel & HDPE)
Return rollers (Steel & HDPE)
