Aggregates & Mining

Processing and handling aggregates such as sand, gravel, limestone, silicates, gypsum is an arduous environment which requires components that are made to withstand these tough conditions.

Our engineers have helped many customers overcome particulary challenging problems, taking time to investigate and often offering custom-tailored solutions.

4B can offer a range of abrasion resistant, heavy duty components, that are made to last and help to avoid unnecessary downtimes.

4B also has a range of heavy-duty hazard monitoring sensors and controls for preventative maintenance.

These systems flag up any hazards such as overheated bearings, belt misalignment, etc so that any failures can be fixed in time before they lead to break-downs, downtimes and potential injury to personnel.

Chain Conveyor Upgrade - Corrosive Products

Customer was struggling with their conveyors transporting a corrosive by-product of crude oil processing. The chain was breaking and wearing fast, causing much downtime. 4B heavy duty links with corrosion-resistant pins and circlips improved the conveyor life by at least 50%.

Elevator handling recycled asphalt planings

Design for a new elevator handling recycled asphalt planings (RAP). Recommending speed, power requirements, shaft & casing sizes, and component specifications (SPS steel buckets and NBR belting), 4B engineers helped the customer to achieve the desired capacity of 250 tph.

Bucket Elevator Upgrade

Consol Glass were experiencing continuous belt breakages and downtime due elevator repairs and maintenance. 4B came up with a revised retrofit design on the elevator components, including AD400 Nyrim buckets and high quality elevator belting. Reducing downtime and planned maintenance and saving on electricity costs.

Bucket Elevator Efficiency Improvement

A potash fertiliser elevator was using solid hardox elevator buckets which were expensive and wearing quickly causing loss of production. 4B solved the problem with wear resistant, self-cleaning Nyrim buckets - fitted with a steel wearband for excellent impact resistance.
