1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar uma planta de britagem de pedreira envolve pressão constante para equilibrar a produção, custo, e confiabilidade. Os desafios operacionais comuns incluem:
Tempo de inatividade não programado: Bearing failures or component wear in primary crushers can halt the entire production line for 2448 horas, costing thousands in lost revenue per hour.
Gradação inconsistente do produto: Flutuações no tamanho da alimentação e na dureza levam a agregados fora das especificações, resultando na rejeição do produto, reesmagamento, e energia desperdiçada.
Altos custos operacionais: Excessive power draw from inefficient crushing chambers and frequent manual adjustments for wear compensation directly erode profit margins.
Dust and Noise Compliance: Failure to meet stringent environmental regulations risks fines, operational shutdowns, and community opposition.

Are you seeking a crushing plant solution that directly addresses these issues through engineered reliability, process control, and measurable operational efficiency?

2. VISÃO GERAL DO PRODUTO

A modern stationary stone quarry crushing plant is an integrated system designed for highvolume primary, secundário, and tertiary reduction of blasted rock into specified aggregate sizes. O fluxo de trabalho operacional normalmente envolve:
1. Britagem Primária: Dump feed is reduced by a jaw or gyratory crusher.
2. Britagem Secundária/Terciária: Cone or impact crushers further process material for precise gradation.
3. Triagem & Classificando: Vibrating screens separate crushed stone into finished product sizes.
4. Manuseio de Materiais: Conveyor networks transport material between stages and to stockpiles.

Application scope includes the production of aggregates for construction, base rodoviária, lastro ferroviário, and concrete/asphalt plants. Key limitations are initial capital investment and the requirement for stable, longterm quarry reserves to justify a fixed installation.

6. CENÁRIOS DE APLICAÇÃO

Projeto de Expansão de Pedreira de Granito

Desafio: An existing quarry needed to double output but faced space constraints and needed stricter control over chip quality for asphalt production.
Solução: Implementation of a compact threestage stone quarry crushing plant featuring a primary jaw crusher, secondary cone crusher with automated settings, and a tertiary vertical shaft impactor for shaping.
Resultados: Taxa de transferência alvo alcançada de 650 TPH within a limited footprint. A cubicidade do produto melhorou de 58% para 78%, meeting premium asphalt mix specifications without additional processing.

Limestone Aggregate Production for Road Base
