The screening basket is a key piece of equipment used in industrial screening operations, primarily for achieving material particle size classification, impurity removal, or solid-liquid separation. Its main structure is a cylindrical screen mesh, made by rolling and welding stainless steel plates (refer to "Stainless Steel Plate Rolling Processing"), with internal support ribs to enhance rigidity. The screen mesh can be either perforated plate (round/square holes) or woven mesh (wire diameter 0.1–5mm), with hole sizes ranging from 0.05 to 50mm, supporting multi-layer stacking designs to meet complex screening requirements. The equipment is driven by a vibration motor or exciter to generate circular motion, pushing materials spirally inside the basket; fine particles pass through the screen holes and discharge, while coarse particles are discharged along the basket wall.
Product Applications
1. Mining and Metallurgy: Dewatering and desliming of iron ore and coal (processing capacity up to 500 tons/hour), particle size classification accuracy ±0.5mm.
2. Building Materials Processing: Grading of sand and gravel aggregates (e.g., 4.75mm, 2.36mm grading), control of manufactured sand modulus, compliant with GB/T 14684 "Construction Sand" standard.
3. Chemical Industry: Screening of fertilizer granules, impurity removal from catalyst carriers, suitable for highly corrosive environments (316L stainless steel material).
4. Food Processing: Grain screening (e.g., wheat impurity removal), starch dehydration, compliant with FDA sanitary design (seamless welding, rounded corners).
Product Features
1. High-Efficiency Screening: Uses patented "spiral rib flow guide" design (spiral ribs inside the basket shown in the figure), reducing material residence time by 30%, screening efficiency >90%.
2. Wear-Resistant and Durable: Screen mesh made of Cr20Ni80 alloy steel (hardness HRC50), lifespan 2–3 times longer than ordinary carbon steel screens.
3. Easy Maintenance: Quick-open clamping device (flange connection on the basket shown in the figure), screen replacement time less than 1 hour.
4. Energy-Saving Operation: Variable frequency vibration motor power only 3–7.5kW (processing capacity 100 tons/hour), energy consumption per ton <0.5kWh/t.
Product Functions
1. Multi-Stage Screening: Supports 1–5 layers of stacked screen meshes (double-layer structure shown in the figure), enabling multi-particle size sorting with a single machine.
2. Self-Cleaning Function: Equipped with ultrasonic cleaning device at the bottom (optional), preventing material clogging of screen holes (e.g., for sticky materials).
3. Sealed Dust Prevention: Fully enclosed structure (basket and inlet/outlet flange seals shown in the figure), dust emission <5mg/m³.
4. Intelligent Control: PLC system monitors amplitude and current in real time, supports remote start/stop and fault diagnosis.
