Crushing & Screening
The TG cone range can also be configured with a secondary upper frame. The TGS configuration can accept a 65-80% larger feed in size compared to all other types of cones in the same power rating, and the steep angled head design accounts for an increased throughput in capacity and the ability to sustain an on/off feed. The consistent feed in opening, through the full wear life of the liners, results in no reduction in maximum feed size and limited fluctuation in output gradings.
The TGS series cones come with advanced automation cone controls as standard. It has numerous choices of crusher cavities and eccentric throws, which allow the cone to be easily adapted to all application requirements at a minimal cost. This, coupled with the exceptional productivity, results in an overall lower cost per ton average.
PowerX Equipment installed two Terex Cedarapids MHS620 Screen Modules with 6’ x 20’ TSV6203 screen and splitter
gates on the three deck MHS module to allow for blending of material to produce various product sizes. The 4-section (25%) blending gate system for the top and middle decks and the 2- section (50%) blending gates for the bottom deck allows for the combining of bottom and fines, centre and bottom, and top and centre deck products.
The MHS620 modular horizontal screen features the extremely efficient Cedarapids® LJ-TSV screen with its legendary ElJay® oval stroke action. The main structure is made from galvanised steel including walkway, steps and handrails. The horizontal screens benefit from an integrated rolling chute mechanism and integrated AR steel fabricated rotational trouser leg chutes.
The screen drive operates at an impressive 40hp (30kW) TEFC motor with V Belt drive standard, motor mount and guarding. The 36” (900mm) under screen conveyor runs an electric 10hp (7.5kW) motor with vulcanised 3-ply belt.
In addition to the TG cone crushers and Terex Cedarapids screen modules, a full conveyor belt package was designed and installed including a new transfer conveyor from the existing processing area to the new recovery tunnel with two feeders by the PowerX Equipment team, completing the plant installation. All conveyors are galvanised and have galvanized covers, which minimises any airborne dust particles. The covers are easily raised and fixed for inspection and maintenance purposes. Access for maintenance for the whole installation was a prime discussion point between the customer and PowerX Equipment. All aspects of the project were discussed and agreed prior to being implemented by the PowerX Equipment design and installation engineers. PowerX Equipment carried out the Principal Contractor role throughout, project management from appointment to handover.
