1. Abertura acionada por PainPoint

Are your sand and gravel processing lines plagued by inconsistent aggregate gradation, levando a cargas rejeitadas e penalidades contratuais? Do you face 1218% material loss during crushing and screening due to outdated equipment design? Is your current setup consuming 30% more power per ton than industry benchmarks, directly eroding your margin on highvolume, lowmargin product?

Para gerentes de fábrica e empreiteiros de engenharia, the operational reality of sand and gravel mining is defined by three factors: throughput reliability, wear part longevity, e qualidade do produto final. When your crusher liners wear out after 400 horas em vez de 800, or your screening efficiency drops below 85%, you are not just losing material—you are losing bid competitiveness.

How can you source a processing system that delivers consistent 05mm manufactured sand with a FM (Fineness Modulus) deviation of less than 0.2, while reducing your total cost of ownership by 1520%? The answer lies in selecting an ODM manufacturer that designs equipment specifically for the abrasive, highvolume demands of sand and gravel mining.

2. Visão geral do produto

This equipment line is a Modular Sand & Gravel Washing and Classification System, designed for dry or wet processing of alluvial and crushed aggregates. O fluxo de trabalho operacional é projetado para, highcapacity production:

1. Alimentar & Escalpelamento: Runofmine material (0300milímetros) enters a vibrating grizzly feeder, removing 50mm fines and directing oversize to the primary jaw crusher.
2. Britagem Primária: A heavyduty jaw crusher reduces material to 150mm, with a hydraulic wedge adjustment for closedside setting (CSS) controlar.
3. Lavando & Esfregar: O material entra em um lavador de toras ou em um lavador rotativo (dependendo do teor de argila) for attrition scrubbing at 200300 RPM, removing deleterious materials and coating from aggregate surfaces.
4. Triagem & Desidratação: A multideck horizontal screen separates material into 34 fractions (por exemplo, 05milímetros, 512milímetros, 1225milímetros). The 5mm slurry is fed to a dewatering screen and hydrocyclone for sand recovery.
5. Estoque: Conveyors with variable speed drives stack finished products, minimizing segregation and maintaining stockpile moisture content below 8%.

Escopo de aplicação: Ideal for riverbed mining, pit run gravel, and hard rock quarries producing concrete aggregates and asphalt base course.
Limitações: Not recommended for materials with high moisture content (>15%) sem pré-secagem, or for processing highly abrasive ores (Mohs >7) without specialized wear liners.

6. Cenários de aplicação

Riverbed Sand & Gravel Processing | Desafio: A contractor in Sichuan, China, was losing 15% of fine sand to the settling pond due to inefficient hydrocyclone design. The existing system produced sand with a high FM (3.2), failing concrete spec. | Solução: Installed our SGM200 system with a 10degree hydrocyclone and dewatering screen. | Resultados: Sand recovery increased to 95%. FM stabilized at 2.8 ±0.1. The client reduced pond cleaning from monthly to quarterly, salvando $18,000 annually in disposal costs.

Pedreira de rocha dura (Granito) for Asphalt | Desafio: A quarry in Fujian needed to produce 05mm manufactured sand for asphalt mix, but their vertical shaft impact (TODOS) crusher produced excessive fines (75 mícron) no 18%, exceeding the 10% limit. | Solução: Integrated our log washer and highfrequency screen after the VSI to scrub and classify the material. | Resultados: Fines content reduced to 8%. The client achieved a 12% increase in asphalt mix yield per ton of feed, directly improving contract profitability by $2.50/ton.

Alluvial Gold & Gravel CoProcessing | Desafio: A mining operation in Indonesia needed to separate goldbearing fines from 0100mm gravel without losing coarse aggregate value. | Solução: Deployed our modular system with a trommel scrubber for clay breakdown and a jig circuit for gold recovery, integrated with the gravel screening line. | Resultados: Recovered 92% of gold in the 2mm fraction while producing clean 2040mm aggregate for local construction. The combined operation reduced processing cost per ton by 30% compared to separate lines.

8. Perguntas frequentes

P: Can this system handle material with high clay content (20%+)?
UM: Sim, but you will need the optional heavyduty log washer with 300 RPM shaft speed and extended 12m tub. Standard log washers are effective up to 10% argila. For higher clay, we recommend a rotary scrubber prestage.

P: What is the typical lead time from order to shipment?
UM: For standard SGM200 systems, lead time is 810 semanas. Customized systems require 1418 semanas, including engineering review and fabrication.

P: How does your ODM process differ from buying from a standard OEM?
UM: Como um ODM, we can modify the equipment design to your specific material characteristics (por exemplo, adjusting crusher chamber profile for your rock type, changing screen deck angles for your feed moisture). Standard OEMs offer fixed designs. We also provide your branding on the equipment if required.

P: What is the expected annual maintenance cost as a percentage of equipment value?
UM: For a 200 TPH plant processing typical river gravel, orçamento 46% of the equipment value annually for wear parts and routine maintenance. For abrasive materials like granite, orçamento 79%.

P: Do you provide performance guarantees in the contract?
UM: Sim. We guarantee throughput (por exemplo, 200 TPH ±5%), sand recovery rate (95% para +75 mícron), and final product moisture content (abaixo 10%). These are verified during the 30day commissioning period.

P: What is the warranty coverage on the main crusher frame?
UM: The main frame and base structure carry a 5year warranty against manufacturing defects. Peças de desgaste (forros, telas, cintos) are covered for 12 months or 2,000 horário de funcionamento, o que ocorrer primeiro.

P: Can the system be integrated with an existing plant control system?
UM: Sim. Our PLC uses standard Modbus TCP/IP protocol. We provide a communication gateway and API documentation for integration with AllenBradley, Siemens, or Schneider systems. Integration typically takes 23 days on site.
