1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar um circuito de britagem de minério de ferro apresenta, desafios dispendiosos. Are you experiencing persistent bottlenecks that limit your plant’s rated throughput? Are unscheduled maintenance stops and premature wear part failures eroding your operating budget and creating unpredictable downtime? Is inconsistent product sizing leading to inefficiencies in downstream grinding and processing, ultimately affecting pellet or sinter quality? Além disso, does the total cost of ownership for your primary crushing stage—factoring in energy consumption, substituições de revestimento, and labor—exceed initial projections? These operational hurdles directly impact profitability. A questão central para os gerentes de fábrica é esta: como você pode alcançar confiabilidade, hightonnage reduction of abrasive iron ore while controlling operational costs and maximizing plant availability?

2. VISÃO GERAL DO PRODUTO

Este produto é um Triturador giratório primário engineered specifically for highcapacity iron ore processing. It is designed as the first critical stage in a mineral processing plant, receiving runofmine (ROM) feed directly from the pit.

Fluxo de Trabalho Operacional:
1. Ingestão de ração: ROM de minério de ferro (tamanho de pedaço de até 1,5 m) is dumped into the crusher’s deep, funil de recepção sem asfixia.
2. Ação Esmagadora: A centrally mounted mantle gyrates within a concave bowl, applying compressive force to break the ore against itself.
3. Descarga: Crushed material exits through the bottom setting (CSS), with product size typically ranging from 150mm to 250mm for feed to secondary crushing or SAG mill circuits.

Escopo de aplicação & Limitações:
Escopo: Ideal for largescale mining operations with high daily tonnage requirements (>10,000 MTD). Adequado para processamento duro, abrasive hematite and magnetite ores.
Limitações: Not designed for final product sizing or for processing materials with high clay or moisture content without adequate prescreening/scalping. Requires a stable concrete foundation and significant headroom for installation and maintenance.
