1. PYNPUNT GEDREWE OPENING

Managing slag stockpiles is a persistent operational and financial drain. Staan jy voor hierdie algemene uitdagings?
Unrecovered Metal Loss: Valuable ferrous and nonferrous metals trapped in slag represent direct revenue loss with every ton processed.
Inefficient Processing: Manual breaking or underpowered crushers lead to bottlenecks, limiting your plant’s overall throughput and creating storage headaches.
Hoë stilstandtyd & Onderhoud: Frequent breakdowns from abrasive slag cause unplanned stoppages, escalating repair costs and labor hours.
Inconsistent Output Size: Poorly sized material complicates downstream handling, magnetiese skeiding, and final product saleability.
Ruimte & Liability Constraints: Growing slag yards consume valuable real estate and present longterm environmental management concerns.

How do you transform this liability into a controlled, profitable recovery stream while ensuring system reliability? Die antwoord lê in 'n doelgerigte slakbrekeraanleg.

2. PRODUK OORSIG

A slag crusher plant is a stationary or semimobile processing system designed specifically for the size reduction and liberation of metallurgical slag (hoogoond, staal oond, koper, ens.). Its primary function is to crush large slag lumps into uniform, graded aggregates to maximize metal recovery via magnetic or eddy current separation.

Operasionele werkvloei:
1. Voer & Voorafskerm: Raw slag from stockpile is fed via loader; an initial grizzly screen removes fine material bypassing the primary crusher.
2. Primêre verplettering: A heavyduty jaw crusher reduces large lumps (dikwels tot 1000 mm) tot 'n hanteerbare grootte (ongeveer. 150200mm).
3. Sekondêre verplettering & Sifting: A cone or impact crusher further reduces material, which is then screened to separate correctly sized product.
4. Metaal skeiding: Sized material passes over suspended magnets or an eddy current separator to extract ferrous and nonferrous metals.
5. Voorraad opgaar: Cleaned aggregate is conveyed to stockpiles for sale or reuse; herwonne metaal word vir herwinning ingesamel.

Toepassingsomvang & Beperkings:
Omvang: Ideaal vir geïntegreerde staalaanlegte, gieterye, smelters, and standalone metal recovery facilities processing blast furnace (BF) slak, beroerte steel (LD beroerte), en nie-ysterhoudende slakke.
Beperkings: Not designed for primary rock mining or extremely highsilica content materials without specific liner configurations. Feed size must be controlled within crusher intake dimensions.

Oplossing: Installation of a dedicated 200 TPH stationary slag crusher plant featuring a heavyduty jaw crusher, twostage screening, and dual magnetic separation stages.
Resultate: Achieved consistent metal recovery rate of over 96%. Produced certified aggregate for road construction. Terugbetalingstydperk bereik in onder 18 months through combined metal revenue and aggregate sales.

Kopersmelter – galmoondslag
