They are widely used in multiple fields such as mining, building materials, chemical industry, metallurgy, transportation, hydropower, coal, refractory materials, etc. We undertake project design for green sand and gravel aggregate grinding production lines and have the "one-stop" engineering service capability of development, manufacturing, installation, commissioning, and operation of complete sets of equipment. We have rich experience and unique technical advantages. We work closely with our clients to develop the best solutions, and have undertaken multiple sand and gravel aggregate grinding production lines in various forms at home and abroad. With its technical strength in the field of sand and gravel aggregate grinding and cost-effective technical solutions, we have won high praise and widespread acclaim from domestic and foreign customers.Bar feeder (also known as bar vibrating feeder) is a core piece of equipment used in mining, building materials, coal, and other industries for "pre-processing of lump/granular materials + uniform feeding." It is particularly suited for coarse, lumpy materials prone to clumping and containing impurities (such as ore, limestone, coke). Its core advantages revolve around "clog-proof and impact-resistant design, uniform feeding, and suitability for harsh operating conditions." Specifically, these advantages can be broken down into the following 6 points:1. Strong anti-clogging capability, suitable for coarse bulk materials and impurity-containing materialsThe core structure of the bar feeder consists of "multiple parallel wear-resistant bars" (rather than traditional conveyor belts or plate structures). This design provides inherent advantages when handling coarse bulk materials and impurity-containing materials: Controllable gaps prevent jamming: The spacing between bars can be adjusted according to material particle size (typically 50-300mm). This allows appropriately sized materials to pass through while intercepting oversized chunks (e.g., blasted ore exceeding 500mm) or contaminants (e.g., soil clumps, metallic debris) on the bar surface, preventing blockages in downstream equipment (e.g., the feed inlet of a jaw crusher);Vibration-Assisted Material Dispersal Prevents Agglomeration: High-frequency vibrations generated by vibrating motors or exciters break up material agglomerations (e.g., wet ore clumps) while promoting uniform flow down the inclined bars. This completely resolves traditional feeder issues like material bridging and inlet blockages, making it ideal for conveying materials during rainy seasons or in humid environments.2. Impact-Resistant and Wear-Resistant for Heavy-Duty Mining ApplicationsMaterials processed in mining (e.g., raw ore, waste rock) feature "large block size, high hardness, and intense impact." The bar feeder's structural design is specifically optimized for heavy-duty conditions: Wear-resistant bar material: Core "feeding bars" utilize high-wear-resistant materials (e.g., ZGMn13 high-manganese steel, KMTBCr26 wear-resistant cast iron) with surface hardness reaching 50-60 HRC and impact toughness ≥15 J/cm2. They withstand repeated impacts and friction from large ore blocks, offering 3-5 times the service life of ordinary steel.Heavy-Load Frame Structure: The body frame is welded from Q355B high-strength carbon steel, with shock-absorbing springs and rigid supports installed at the base. It can withstand impacts from ore blocks weighing 1-5 tons each, preventing frame deformation or cracking, and meets the mining industry's demand for "24-hour continuous high-intensity operation."3. Uniform and stable feeding ensures efficient operation of downstream equipmentThe bar-type feeder employs an "adjustable vibration frequency + amplitude" design to precisely control material throughput, providing stable feeding for subsequent crushing and screening equipment. This prevents "overload jamming" or "underload idling": Wide controllable throughput range: By adjusting the excitation force of the vibration motor (e.g., altering the angle of eccentric weights), continuous throughput adjustment from 0-1000m3/h is achievable (different models accommodate varying capacities, e.g., the compact ZG-30 model handles 30-80m3/h, while the large ZG-120 model reaches 800-1200m3/h), accommodating diverse capacity requirements from small-to-medium mines to large mineral processing plants;Excellent feeding continuity: Material forms a "uniform layer" on the bars and slides down via vibration, eliminating pulsed feeding. This ensures subsequent jaw crushers and cone crushers consistently operate at "rated load," boosting crushing efficiency by 10%-15% while reducing equipment wear and failures caused by "sudden load fluctuations."4. Integrated pre-screening function reduces downstream equipment loadWhile feeding, the bar grate feeder simultaneously performs "pre-screening," separating fine particles and impurities in advance to lower processing demands on subsequent crushing equipment: - Fine material pre-separation: When processing materials with high fine powder content (e.g., weathered ore, crushed return material), fine particles (smaller than bar gaps) fall directly through the bars onto the conveyor belt or storage bin below, bypassing the crusher. This eliminates "unproductive work" by the crusher, reducing energy consumption and wear on vulnerable components (e.g., crushing plates).Convenient impurity removal: Oversized lumps and contaminants (e.g., wood, metal) trapped on the bar surface can be swiftly cleared manually or via an "automatic cleaning device" (e.g., scrapers, hydraulic push rods) without shutdown, ensuring continuous production line operation. This is particularly suited for mining scenarios with high impurity levels requiring frequent cleaning.5. Simple structure, low maintenance costs, and easy operationCompared to complex plate feeders or belt feeders, bar feeders feature fewer components and wear parts, making daily maintenance and operation extremely straightforward: Few wear parts with easy replacement: Core wear components are only the "feeding bars" and "vibration damping springs." Bars are bolted in place, allowing replacement without disassembling the entire unit. A single operator can complete the task in just 1-2 hours (compared to 4-6 hours for replacing chain plates in traditional plate feeders).Low maintenance costs: Absent complex drive systems (e.g., chains, gearboxes), routine maintenance involves only periodic inspection of bar wear, bolt tightening, and lubricant replenishment (vibration motor bearings). Annual maintenance expenses amount to just 50%-60% of plate feeders.Simple operation: Features "one-button start/stop + knob speed adjustment" control with vibration frequency display and overload alarm. Operators can be trained quickly without requiring specialized technical personnel.6. Strong environmental adaptability with excellent weather resistance and dustproofingMining environments are typically "open-pit, dusty, high-humidity, and subject to large temperature fluctuations." The bar feeder's targeted design ensures adaptability to harsh conditions: Weather resistance: Vibration motors feature IP54 or higher protection ratings, enabling stable operation within -30°C to 50°C (motor heating devices can be added for low-temperature environments), suitable for northern winter open-pit mines and southern high-temperature/high-humidity mines.Dust and Splash Protection: Optional "enclosed dust covers" prevent dust dispersion during material conveyance, meeting mining environmental standards (e.g., dust emission ≤10mg/m3). The bar structure eliminates recessed material accumulation zones, preventing damp material adhesion and avoiding failures caused by "material buildup, mold growth, or equipment corrosion."SummaryThe core advantages of the bar grate feeder can be summarized as "clog-resistant and durable, integrated material distribution and screening, and easy maintenance." It is particularly suited for the mining industry's needs in handling coarse, lumpy materials and materials containing impurities, making it the preferred equipment for "front-end feeding in mining crushing production lines." It not only ensures efficient operation of downstream equipment but also reduces energy consumption and maintenance costs, making it widely applied in small-to-medium-sized mines, sand and gravel aggregate plants, building materials factories, and similar scenarios.
