1. ABERTURA ACIONADA POR PAINPOINT

Managing a Chinese stone quarry crushing plant presents distinct operational and financial pressures. Você está enfrentando esses desafios comuns?
Tempo de inatividade não planejado: Frequent mechanical failures in crushers or conveyors halt your entire production line, custando milhares por hora em perda de produção e mão de obra ociosa.
Gradação inconsistente do produto: Flutuações no tamanho final do agregado levam à rejeição do produto, forcing reprocessing and damaging your reputation with asphalt and concrete batch plant customers.
Alto consumo de peças de desgaste: A natureza abrasiva do granito, basalto, ou calcário degrada rapidamente os revestimentos, maxilas, e barras de sopro, creating unsustainable costs for spare parts inventory and replacement labor.
Ineficiência Energética: Mais velho, singlestage or poorly configured crushing circuits consume excessive power per ton of processed material, corroendo as margens de lucro.
Conformidade com poeira e ruído: Increasingly stringent environmental regulations require significant investment in control systems to avoid fines and operational shutdowns.

How do you transform these cost centers into controlled variables? The solution lies in specifying a modern, integrated planta de britagem de pedra chinesa designed for total cost of ownership.

2. VISÃO GERAL DO PRODUTO

Um moderno planta de britagem de pedra chinesa is a stationary or semimobile hard rock processing system engineered to transform blasted quarry feed (typically 0750mm) into precisely graded commercial aggregates (por exemplo, 05milímetros, 510milímetros, 1020milímetros). It is not a single machine but a synchronized circuit of primary, secundário, and tertiary crushing stages with integrated screening and material handling.

Fluxo de Trabalho Operacional:
1. Redução Primária: Caminhões basculantes alimentam a rocha explodida em um britador de mandíbula primário para redução inicial do tamanho.
2. Pré-triagem & Britagem Secundária: A vibrating grizzly feeder removes fines before coarse material is conveyed to a secondary cone crusher for further reduction.
3. ClosedCircuit Tertiary Crushing & Triagem: O material é então peneirado; oversize is recirculated through a tertiary cone or impact crusher in a closed loop to achieve precise final gradation.
4. Estoque: Correctly sized aggregates are conveyed to designated stockpiles via radial stackers.

Escopo de aplicação & Limitações:
Escopo: Optimized for mediumtohigh volume production (150800 TPH) of construction aggregates from hard rock (resistência à compressão >150MPa). Ideal for largescale infrastructure projects requiring consistent, highspecification material.
Limitações: Not suitable for soft minerals or sandonly production without significant circuit modification. Requires substantial capital investment and prepared site infrastructure (fundações, power supply).
