This configuration utilizes an eccentric shaft or vibration motor to create a linear trajectory, which is generally preferred for high-capacity solids removal in drilling operations. The vibration amplitude observed in specific models is approximately 5mm, while the vibration intensity can reach 6.5g. These parameters are critical for ensuring that the screen effectively stratifies the drilling fluid, allowing fine particles to pass through while retaining larger cuttings for disposal.

The screen specification is another vital technical attribute. Units often feature screens with dimensions such as 1165x585x40mm, providing a total screening area of roughly 3.4 square meters. The mesh shape can vary between circular and rectangular configurations, with mesh numbers like 18-Type available for specific filtration needs. The structure of the machine is typically vertical, and the power source is electric, often utilizing dual motors rated at 2x2.2kw. Buyers should verify that the motor type is explosion-proof, a standard requirement for hazardous environments found in oilfield drilling sites. The material composition of the shaker body is predominantly steel, with specific models utilizing stainless steel or cast steel to resist corrosion from drilling fluids. Some units may also incorporate alloy components to enhance durability under high-stress conditions.

Compliance, Certification, and Safety Standards

In the oil and gas sector, regulatory compliance is non-negotiable. When sourcing shale shakers, buyers must verify that the equipment meets international quality and safety standards. The most common certification observed in the market is ISO 9001, often cited in conjunction with specific operational years like 2015. Additionally, safety certifications such as CE and RoHS are frequently present, indicating compliance with European health, safety, and environmental protection standards. It is crucial to note that certification statuses can vary between individual products; therefore, buyers should request valid certificates for the specific model being purchased rather than assuming blanket compliance.

Safety in explosive atmospheres is paramount. The presence of explosion-proof motors is a key indicator of a unit's suitability for hazardous drilling zones. Buyers must confirm that the electrical components are rated for the specific zone classification required by their site. Furthermore, the working pressure of these units is typically atmospheric, meaning they are designed to operate under standard pressure conditions without pressurization. However, the operating environment must be strictly controlled. Documentation should clearly state the certification scope, ensuring that the ISO 9001:Operation Pressure:Atmospheric Pressure claim is valid for the specific equipment configuration.

Cost Drivers and Pricing Variables

The price range for oilfield shale shakers is highly variable, observed to span from $1 to $56,000 USD. This wide disparity is driven by several factors, including the complexity of the design, the quality of materials used, and the level of customization required. Basic models with standard specifications will naturally fall on the lower end of the spectrum, while heavy-duty units with advanced features, such as multilayer screens or custom-made dimensions, will command higher prices.

Material costs play a significant role in pricing. Units constructed from stainless steel or specialized alloys will be more expensive than those made from standard carbon steel or cast steel. The manufacturing process also influences cost; forging is a common process that adds strength but may increase production expenses compared to casting alone. Surface treatments, such as spray-painting, are essential for corrosion resistance and add to the overall cost. Buyers should be wary of prices that seem abnormally low, as they may indicate inferior materials or a lack of necessary certifications. Additionally, the total cost of ownership should include shipping, which is typically containerized by sea, and the cost of replacement screens, which are consumable items with varying lifespans.

Typical Applications and Operational Context

Oilfield shale shakers are primarily designed for oilfield drilling solid control applications. Their main function is to separate solids from the drilling fluid, a process that is critical for maintaining the efficiency of the drilling operation. The applicable medium for these machines is mud, which can contain a wide range of particle sizes depending on the geological formation being drilled. The capacity of these units can range from 45 to 140 cubic meters per hour, making them suitable for various drilling scenarios, from exploration wells to deep drilling operations.

The application extends beyond simple drilling to include broader energy and mining sectors, specifically petroleum machinery parts. The versatility of the design allows for use in different drilling environments, provided the equipment meets the necessary safety and performance standards. The machine type is often classified specifically as an oilfield shale shaker, distinguishing it from general industrial vibrating screens. Buyers should ensure that the selected unit matches the specific requirements of their drilling fluid system, including the viscosity and density of the mud being processed.

Supplier Evaluation and Origin Verification

When evaluating suppliers, the origin of the product is a significant factor. Most observed units originate from China, with specific manufacturing hubs identified in locations such as Dongying. The delivery port is often listed as XinGang, which buyers should consider when calculating logistics and lead times. The manufacturing process, such as forging, and the surface treatment methods should be clearly documented by the supplier.

Suppliers should demonstrate a commitment to quality through their certification records. A supplier offering ISO 9001:ISO 9001:RoHS,CE certification is likely to have robust quality control systems in place. However, buyers must verify that these certifications are current and applicable to the specific product line. Customization availability is another key indicator of a supplier's flexibility. Many suppliers offer customization options, allowing buyers to tailor the machine dimensions, such as the standard size of 2000x1700x1500 mm or custom-made specifications like 3963x3025x2410 mm, to fit their specific site requirements.

Quality Control and Packaging Standards

Quality control extends beyond the manufacturing process to include packaging and shipping. Proper packaging is essential to prevent damage during transit, especially for heavy machinery. Observed packaging methods include containerized shipping by sea, wooden box packing, and export packing. The specific packing method should be clearly defined in the purchase agreement to ensure that the equipment arrives in optimal condition. For instance, some units are packed in wooden boxes, while others may use standard export packing.

Buyers should also inspect the physical attributes of the machine upon receipt. The structure should be vertical, and the vibration type should match the specifications (linear motion). The screen specification, including the mesh shape and number, must be verified against the order. Any discrepancies in the material, such as the presence of cast steel versus alloy, should be immediately addressed. The manufacturing process, including surface treatments like spray-painting, should be uniform and free from defects that could compromise the machine's longevity.

Long-Term Procurement Considerations

Sourcing oilfield shale shakers is not just a one-time transaction but a long-term partnership. Buyers should consider the availability of spare parts, such as screens and motors, when selecting a supplier. The total area of the screen and the vibration intensity are critical for long-term performance, and any deviation from the specified values can lead to reduced efficiency. The lead time and delivery port, such as XinGang, should be factored into the project timeline to avoid delays.

Furthermore, the customization capabilities of the supplier can be a deciding factor for future projects. If a buyer requires a machine with specific dimensions, such as 3140x1980x1540mm, the supplier must be able to accommodate these requests. The layer configuration, such as multilayer screens, should be evaluated for its impact on long-term maintenance and operational efficiency. By focusing on these long-term factors, buyers can ensure that their investment in oilfield shale shakers delivers consistent performance and value over the lifespan of the drilling operation.
