खनन उपकरण गाइड: What Equipment Should You Use for Continuous Feeding in Mining, Metallurgy and Building Materials? A Complete Guide to BW Series Chain Feeders

The chain plate feeder (abbreviated as plate feeder) is a type of bulk material conveying equipment that converts intermittent feeding into continuous feeding. Our company, by introducing advanced foreign technology, has newly developed the BW type and BZ type plate feeders, which feature high traction, minimal material leakage, stable operation, long service life, and easy maintenance. These are indispensable continuous feeding devices in industries such as mining, metallurgy, building materials, chemical, and coal mining. Why choose a chain plate feeder? First, it has high traction, capable of bearing the continuous conveying pressure of large and heavy materials. Second, it has minimal material leakage, adopting a reasonable trough plate design to reduce material spillage during conveying. Third, it operates smoothly, with precise meshing between the chain and sprockets ensuring long-term stable operation. Fourth, it has a long service life, as key components are made of high-strength wear-resistant materials, suitable for harsh working conditions. Fifth, maintenance is convenient; modular design allows for quick replacement of wear parts, reducing downtime. Chain plate feeders are mainly used for feeding before primary crushing in mining, feeding sinter and pellet ores in the metallurgical industry, feeding cement clinker and limestone in the building materials industry, feeding block raw materials in the chemical industry, feeding raw coal and gangue in coal mines, as well as in various industrial scenarios that require continuous and uniform transmission of large chunks of bulk materials from silos to crushers or other receiving equipment. The target users for chain plate feeders include equipment procurement and operation & maintenance departments of mining companies, metallurgical plants, building materials factories, cement plants, chemical plants, and coal mining enterprises, as well as EPC contractors for bulk material handling production lines, equipment dealers and stockists, and overseas industrial and mining project purchasers. When should a chain plate feeder be chosen or replaced? When there is a need to convert intermittent feeding into continuous feeding; when the material has large particle size (≤350-≤1500mm), high bulk density, high temperature, or abrasiveness; when old vibrating feeders or plate feeders have serious material leakage, insufficient traction, or high failure rates; when a new mining, metallurgical, or building materials production line requires heavy-duty continuous feeding equipment; or when export projects require adaptation to overseas voltage and heavy-duty feeding conditions, the BW type chain plate feeder should be given priority. How to select a chain plate feeder? The first step is to confirm the material characteristics and determine suitability based on material particle size (≤350-≤1500mm), bulk density, and temperature. Step 2: Confirm processing capacity. Select the corresponding model within the 18-1250 t/h range according to the production line capacity requirements. Step 3: Confirm the trough plate width. Choose 800-2500 mm based on the processing volume and material particle size. Step 4: Confirm the center distance. Choose 3-20 m according to the process layout and conveying distance. Step 5: Confirm motor power. Select 2.2-45 kW according to processing capacity and conveying length. Step 6: Confirm the installation foundation. It must be installed on a solid concrete foundation and fixed with anchor bolts. Step 7: Confirm the feeding and discharge port connections to ensure smooth material flow. Step 8: Confirm environmental and automation configurations, which can be equipped with dust removal systems, variable frequency speed control, and central control systems.

Installation method

The chain plate feeder must be installed on a solid concrete foundation, which needs to bear the weight of the equipment and the dynamic load during operation; during installation, ensure that the foundation is level according to requirements, and tighten the anchor bolts according to torque specifications. After the equipment is in place, adjust the leveling to ensure that the frame is parallel to the drive shaft, the chain tension is appropriate, and the trough plates are securely connected. The feed inlet and outlet must be well sealed to the hopper and receiving equipment to prevent leakage. After installation, perform a no-load test run to check whether the chain runs smoothly, whether there is any abnormal vibration or noise, and confirm that the trough plates are not stuck. For the load test run, gradually increase the feeding quantity, observe the conveying effect and motor current, and ensure it does not exceed the rated current. A dust removal system must be equipped to reduce dust pollution; a central control system can be installed for online monitoring and automatic control.
