Uniform, vertical, and smooth pulse lines with no disconnections or breaks;2. High precision, unlimited number of pulses, fine line size can reach 0.01mm;3. Strong shock resistance, with extremely high mechanical strength and pressure resistance;4. Reflective materials can be added to create reflective code discs;Precision: Tolerance ±0.002mm (i.e., 2 microns);Delivery Time: Standard sampling 3-5 days, delivery 5-7 days.Application: Digital encoder for measuring angular displacement. It offers strong resolution, high measurement accuracy, and reliable performance, making it a commonly used displacement sensor for measuring shaft rotation angle.A code disc (grating disc) has several rectangular holes evenly distributed on a circular plate of a certain diameter. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed as the motor. The detection device, composed of electronic components such as light-emitting diodes, detects and outputs several pulse signals. By calculating the number of pulses output by the photoelectric encoder per second, the current speed of the motor can be determined.125 more>

MFD350 Nylon Column Cap swiftly replaced with the matching set to secure the pillar and prevent slipping.
$80
Category: Interwoven Fabric
Company: Yantai Lesen Machinery Equipment Co., Ltd
Product Description: Due to fluctuations in raw material prices, the pricing and models may vary. For specific quotations, please contact our sales representatives. Thank you.If the underground support is slightly twisted, try replacing it with a matching nylon column cap—its grooves can secure the pillar, and its thick disc surface allows for fine adjustments according to the roof angle, gradually "straightening" the twisted force and realigning the pillar. This small component may seem simple, but at critical moments, it can pull off-track support back on course, creating a safe space~Mine-used column shoes and caps are primarily used for support in coal mines and other mining tunnels or工作面. They enhance support stability through the initial support force and roof-thrust force of individual pillars, preventing roof accidents.Specific Uses:Enhancing Support Stability: By utilizing the initial support force (the pillar's initial bearing capacity) and roof-thrust force (the pillar's pushing force against the roof), they effectively control roof subsidence and ensure operational safety.Adapting to Complex Geological Conditions: Suitable for scenarios requiring temporary support, such as coal mining faces and tunnels, particularly in areas with high roof pressure or complex geological conditions.Materials and Craftsmanship: Common materials include cast iron and nylon. Nylon offers anti-static properties and lightweight characteristics, meeting the requirements for equipment lightweighting and safety in underground operations.Specifications and Compatibility:Common diameters include 260mm, 280mm, 300mm, 320mm, and 350mm. Custom non-standard specifications can also be produced based on actual needs.These seemingly simple design details—every curve and every interface—ensure that the column shoes fit perfectly in the complex environment of mines, with dimensions meticulously matched for optimal performance. more>

Purification of dust-producing operation points with 37kw spray-type mining wet dust removal fan, simple structure.
$12500
Category: Machinery & Equipment/Desulfurization & Dust Removal/Dust Collectors
Company: Yantai Lesen Machinery Equipment Co., Ltd
Product Description: Due to fluctuations in raw material prices, the prices and models may vary. For specific quotations, please contact our sales staff. Thank you.The tunnel KCS-230 wet dust removal fan is used from small cross-section tunneling to high-power coal mining, primarily to improve mine ventilation and capture dust. Mining dust removal fans are mainly used to eliminate dust generated during mining operations. In processes such as mining, crushing, and transportation, dust generation is inevitable. Long-term exposure to high concentrations of dust can affect workers' respiratory systems. High air volume demonstrates strength. Stability is the fundamental principle.How does the mining dust removal fan operate? It consists of a mining ventilation fan and a wet string dust collector. Dust-laden air is drawn in by the dust removal fan, and the dust is captured by the wet string dust collector, achieving on-site dust removal and purification. The purified airflow is discharged from the outlet of the dust collector, achieving the purpose of purification.Main Technical Parameters1. Total dust removal rate: ≥97%2. Liquid ratio: ≤0.4L/m³3. Air handling capacity m³/s: Series models.4. Applicable dust concentration range: C≤24000mg/m³ air handling capacity.5. Operating mode: Continuous operation.6. Applicable ambient temperature: 0℃~40℃.7. Applicable dust types: Hydrophilic dust such as coal, rock, cement, etc.Simply put, this is a "water suppression" method, where the fan sprays water mist onto dust-generating points, allowing dust particles to combine with water droplets, become heavier, and settle. more>

Category: Machinery & Equipment/Valves/Discharge Valves
Company: Hebei Naixin Environmental Protection Technology Co., Ltd.
Product Description: Customized rectangular port woodworking dust removal discharge valve sawdust rotary ash discharge valve, Pressure-resistant type: It adopts a closed rotor, which can be widely used in suction-type, pressure-type airflow conveying systems and negative pressure conveying equipment. It ensures that the airflow pressure in the conveying pipe does not leak, enabling safe transportation and collection of materials. Therefore, it is referred to as a universal airlock in this regard. It is not only pressure-resistant but also incorporates the functions of a standard type.Star-type ash discharge valves are divided into circular star-type ash discharge valves and square star-type ash discharge valves based on their external structure. Their advantages include: stable and reliable operation, uniform and accurate discharge, optimized structure, compact size, excellent sealing performance, easy maintenance, lightweight and energy-saving, long service life, etc. They are also indispensable equipment in dry material, dust, particle, and solid conveying systems. This valve is installed at the ash discharge outlet of dust collector hoppers and is widely used in feeding and ash discharge systems in industries such as chemical, metallurgy, mining, cement, dust removal, environmental protection, power, and grain. Customized non-standard star-type ash discharge valves are also available according to customer requirements.A device that transports materials away. Therefore, the star-type ash discharge valve can only be installed vertically and is not allowed to be installed horizontally. A certain material column must be maintained above the feeder.This valve is also known as a star-shaped ash discharge valve, star-type discharger, or rotary feeder. It consists of a valve body, transmission shaft, blades, and reducer. The geared motor drives the transmission shaft and impeller to rotate, thereby achieving ash discharge. It features wear-resistant blades, high airlock performance, thorough discharge, smooth connection, and compact structure. The elastic impeller feeder uses an elastic rotor for better sealing, ensuring uniform feeding.The rigid impeller feeder consists of a rotating impeller with compartments, a body, and a new cycloidal pinwheel reduction motor, among other components. It is compact, reliable, and offers excellent sealing and wear resistance. The working principle of the rigid impeller feeder is that when the impeller is driven by the transmission mechanism to rotate within the body, powdered or granular materials falling from the upper separator (or hopper) enter the impeller compartments through the feed port and are conveyed to the discharge port as the impeller rotates. Throughout the process, it enables continuous and quantitative feeding and discharging.Customized rectangular port woodworking dust removal discharge valve sawdust rotary ash discharge valve. more>
