The company adheres to the principle of honest service and focuses on the production of 325*3-meter tubular screw conveyors.
Core parameters and product information of 325*3-meter tubular screw conveyor
325*3 meters refers to the pipe diameter of the tubular screw conveyor being 325 millimeters, and the transportation length being 3 meters. It is a commonly used medium-sized tubular screw transportation equipment in industries such as environmental protection, building materials, chemical engineering, and grain processing. It is mainly used for sealed transportation, has a small floor area, flexible transportation direction, and is suitable for powder, small particle materials (such as fly ash, cement, grain, sand and stone powder, etc.). .
Key performance parameters (standard configuration)
Discharge capacity: Horizontal conveying time is approximately 15 - 25 meters per hour. ³/h (for powdery materials, the value is low; for small particle materials, it is high; for inclined conveying, the value should be reduced);
Speed: The rotational speed of the screw shaft is approximately 30 - 60 r/min (low-speed operation, reducing material fragmentation and equipment wear).
Drive power: Standard equipped with 3kW - 5.5kW reduction motors (the power increases as the material ratio or conveying angle increases; the higher the ratio or the greater the angle, the higher the power).
Transmission method: Direct connection to the deceleration motor (coaxial transmission, small floor space, high transmission efficiency, suitable for 3-meter short-distance transportation);
Sealing method: Flange sealing method, shaft end packing seal / mechanical seal. The entire pipe body is sealed, there is no dust leakage, and it complies with environmental protection requirements.
Structural feature (exclusive for 3-meter short-distance use)
Single-section integral tubular structure, without intermediate suspension bearings, reduces material jamming faults and makes maintenance much simpler.
2. The feed inlet can be selected as a feed inlet (flanged type / square hopper type), and the discharge outlet is a discharge port (the discharge position can be adjusted as needed). It is suitable for on-site silos and equipment connection.
The body is lightweight (about 200-300 kg for the carbon steel model), easy to install, and can be fixed directly to the ground or installed with brackets.
The spiral shaft is made of solid shaft or thick-walled hollow shaft, which has good strength and is suitable for 3-meter short-distance unsupported operation.
Applicable to materials and scenarios
Compatible materials
Powder form: fly ash, cement, lime powder, flour, wood powder;
Fine particles: Sand and gravel powder, grains, plastic particles, fertilizer particles (particle size) ≤ 20mm, non-viscous, without large chunks.
Applicable scenarios
Environmental protection industry: Dust transportation from the dust collection bin, transportation of small particles of desulfurization gypsum;
Building materials industry: Powder transportation from cement silos to mixers, and short-distance transportation of sand and gravel powder;
Grain/Chemical: Small silo for granular and powder materials, with quantitative/non-quantitative conveying capabilities.
Customization and Selection Points
Material customization: Corrosive materials are made of 304/316 stainless steel. Due to high performance requirements, carbon steel liners with wear-resistant properties are selected (based on actual reports)(based on actual reports). The plates are made of carbon steel liners with wear-resistant properties.
Customized feeding/outlet options: Bucket-type feeding is suitable for manual feeding, while flange-type feeding is compatible with equipment connection and can incorporate regulating valves to control the conveying volume.
Motor selection: Explosion-proof (based on actual reports) (based on actual reports) Environmental selection for explosion-proof (based on actual reports) (based on actual reports) Reducing gear motor, variable frequency requirement selection for variable frequency motor, enabling speed adjustment and controllable conveying capacity;
Installation options: Fixed base for floor-mounted models, and swivel wheels for mobile models (suitable for temporary transportation needs);
Auxiliary components: Additional features such as level gauges, speedometers, and emergency stop switches can be installed to enhance the safety and controllability of the equipment operation.
Daily Maintenance 6. Daily Maintenance
Regularly inspect the shaft end seals to prevent material leakage and dust ingress. Replace the packing/ mechanical seals in a timely manner when they are worn out.
The deceleration motor should have its lubricating oil refilled or replaced regularly, following the instructions in the motor manual. Avoid running the motor with insufficient oil.
Before starting the operation, check that there is no obstruction between the spiral shaft and the pipe body, and that there are no large foreign objects in the material to prevent the equipment from overloading.
Carry out a long-term shutdown to clean the residual materials inside the pipe, to prevent the materials from caking and to avoid corrosion of the pipe body and the spiral blades.
