1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar uma pedreira em Lagos apresenta obstáculos operacionais distintos que impactam diretamente seus resultados financeiros. Are you contending with unpredictable bedrock hardness that leads to premature wear on crusher components? Are you losing valuable production hours to excessive dust generation, causing site shutdowns and community complaints? Is the high cost of diesel fuel for mobile equipment eroding your profit margins on every ton of aggregate produced? Além disso, do inconsistent feed sizes from primary breaking cause bottlenecks in your secondary crushing circuit, limitando o rendimento geral da planta? Esses desafios se traduzem em perdas quantificáveis: tempo de inatividade não planejado, soaring maintenance costs, reduced equipment lifespan, and failure to meet project deadlines. The central question for a commercial buyer is this: como você pode alcançar resultados consistentes, highvolume aggregate production in Lagos’s demanding environment while systematically controlling operational expenses?

2. VISÃO GERAL DO PRODUTO

The solution is a stationary primary jaw crusher plant, engineered specifically for the granite and hard rock quarries prevalent in the Lagos region. This heavyduty equipment serves as the foundational first stage in your mineral processing workflow.

Fluxo de Trabalho Operacional:
1. Alimentar: Dump trucks or loaders deposit large blasted rock (typically up to 800mm) into the plant’s reinforced hopper.
2. Esmagamento: A robust jaw crusher applies compressive force to reduce the rock to a manageable size (typically 150200mm).
3. Pré-triagem & Transporte: Integrated grizzly screens bypass subsize material directly onto the main product conveyor, while crushed material is conveyed for secondary processing or stockpiling.

Escopo de aplicação: This plant is designed for highcapacity primary reduction of hard, materiais abrasivos como granito, basalto, e quartzito. It is the core of a fixed or semifixed quarry installation.

Limitações: It is not suitable for mobile ondemand crushing applications or for processing soft, nonabrasive materials like limestone where alternative crusher types may offer efficiency advantages. Optimal operation requires a stable, prepared site foundation.
