Dosage Feeding MachineAlso known asBelt Scales, Electronic Belt ScalesIngredient scale, batching belt scale, or belt batching scale. Typically,Electronic Belt ScaleCan only measure the flow of materials.Quantitative Feeding MachineThe belt feed scale can measure the flow rate of materials and, on the other hand, should convey materials from the hopper at a preset flow rate. Foreign manufacturers refer to the batching belt scale (measuring feeder) as a weighing feeder and a weighing belt feeder. Below is an introduction to some situations of the measuring feeder (batching scale), hoping it will be helpful to everyone.

Features of the Quantitative Feeding Machine

The high-reliability variable-frequency speed control technology of the dosing machine features wide belt width, thick material layer, low-speed operation, ensuring stable performance and nearly static measurement accuracy. Dynamic measurement accuracy exceeds 1.0%; static measurement accuracy exceeds 0.5%, with precision models reaching 0.125%. The dosing machine boasts high automatic dosing accuracy with a wide adjustment range (speed ratio ≥20:1, belt speed 5cm/min to 15m/min). It exhibits excellent linear speed control at low speeds, significantly reducing belt wear and preventing damage to large pieces of material.

The performance-to-price ratio of the batching machine is excellent. Utilizing new technology and years of practical experience, it has been continuously improved and refined, achieving features such as automatic belt centering, automatic tension adjustment, profile cleaner, and dust-proof roller bearing design. It boasts high control precision and stability, with a price just 1/4 to 1/5 of imported counterparts. The operation and maintenance costs of the batching machine are low. Under normal operation, the belt life can last up to 5 years, saving energy by 20% to 40%. A special quick belt replacement method requires only two people for a rapid belt change. Based on the company's "tailor-made" technical requirements, on-site design is conducted to ensure rational selection and reliable operation. The configuration is flexible, allowing the selection of different types of equipment according to process requirements, such as cement batching lines, high-temperature-resistant belt scales; and powdered materials, sealed belt scales. The batching machine belts are available in various widths of 500/650/800/1000/1200mm, suitable for material flow rates of 1 to 150 tons per hour. Equipped with 4-20mA or 0-10V standard signals, it can interface with industrial computers or DCS systems.

Dosage Feeding Machines and Dosage Feed Scales

The volumetric feeders and feed hopper bodies are independently developed and designed based on the introduction of technology and the integration of over 20 years of research and development experience. The new generation products not only retain the advantages of the volumetric feed scales but also boast an aesthetically pleasing, compact design. The bending forming frame and挡板 are rigid, and the single-bar, single-roller spring leaf support method is simple and stable.

2. The original new tail frame is equipped with spherical self-aligning ball bearings, which are built-in bearings; the adjustment and tensioning of the bolt rod have been changed to a simple slider adjustment, making the weighing body simpler, more reliable, safer, more convenient, more aesthetically pleasing, and less prone to accumulation. Due to the unique structure of the ends and cushion blocks, the belt can be easily and quickly removed without dismantling the roller, cleaner, legs, and other devices during use, saving time and effort, and outperforming similar domestic products and foreign counterparts.

The design features a trapezoidal cross-section with wedge-shaped sloping edges, offering a larger volume and rationally designed feeding hoppers. It ensures the material remains loose, smooth, uniform, and stable, significantly reducing the occurrence of material blockages and belt abrasion.

 4. ZTThe series of quantitative feeding scales utilize larger diameter drum-shaped coated buckets. With high friction resistance, large belt wrap angle, and minimal stress, the tension remains stable, ensuring the belt does not slip, extending its service life, and accurately measuring speed. It also plays a role in adjusting deviations and stabilizing the belt, outperforming similar products.

The perfect integration of gravity tension with automatic deviation adjustment mechanisms, supplemented by a waist drum-shaped drum and screw slider adjustment mechanism, ensures stable belt tension, flexible, quick, simple, and convenient adjustment. The unique super-tension roller, eccentric adjustment mechanism, and adjustable support methods both improve the system's flexibility and effectiveness and simplify the weighing structure, making it easier to regulate, providing great convenience to users.

6. Maintained the unique structure of the vacuum cleaner on the scale, which differs from the connection and fixation method of the scale's shaft. This allows for a stable relative position with the roller, automatically clearing any fallen materials and debris and depositing them on the lower conveyor belt. This effectively prevents paper jams from damaging the belt and ensures smooth and stable operation.
