Introduction to 50 Kg Gross Weighing Machine Supplier
A 50 Kg Gross Weighing Machine is a specialized industrial bagging solution where the weighing process takes place directly inside the bag during the filling operation. Unlike net weighing systems that weigh material in a hopper first, a gross weigher clamps the bag onto the load cell system, auto-tares the bag weight, and fills until the target gross weight is achieved. As a leading supplier, Samirika Group provides high-performance gross weighing machines designed for materials where moderate speed and high reliability are required. These machines are particularly effective for handling powders, flakes, and granules in industries ranging from agriculture to petrochemicals.
Working Principle and Process Flow of 50 Kg Gross Weighing Machine
The operation of a 50 Kg Gross Weighing Machine centers on a "weigh-in-bag" technique. The operator places an empty bag onto the filling spout, where it is secured by pneumatic clamps. The system automatically zeros out the weight of the bag (tare). The material is then fed directly into the bag through a specific feeding mechanism (gravity, belt, screw, or vibration). As the bag fills, the load cells continuously monitor the increasing weight. The controller switches from coarse feed (fast filling) to fine feed (trickle filling) as it approaches the set target, ensuring precise accuracy before automatically releasing the filled bag onto a conveyor.
Types of 50 Kg Gross Weighing Machines We Supply
- Screw Feeder Gross Weighers – Specifically designed for fine powders like flour, cement, and chemicals to prevent flushing and ensure steady flow.
- Gravity Feeder Gross Weighers – Ideal for free-flowing granular products such as plastic pellets, rice, sugar, and fertilizers.
- Belt Feeder Gross Weighers – Perfect for handling non-free-flowing or lumpy materials like animal feed mash, compost, and soil.
- Valve Bag Gross Weighers – Specialized systems for self-sealing valve bags, commonly used in construction and chemical industries for dust-free filling.
- Vibratory Gross Weighers – Used for fragile or irregular materials that require gentle handling during the direct-to-bag filling process.
Key Features and Specifications
- Direct weighing mechanism where the bag itself acts as the weighing vessel.
- Heavy-duty pneumatic bag clamping system to securely hold 50 kg bags during filling.
- User-friendly digital controller with auto-tare and auto-calibration functions.
- Compact vertical design requiring less headroom compared to net weighing systems.
- Dual-speed filling (coarse and fine) to optimize speed while maintaining high accuracy.
Applications of 50 Kg Gross Weighing Machine
- Chemical Industry – Used for bagging PVC resins, plastic granules, and various chemical powders into open-mouth or valve bags.
- Agriculture and Farming – Ideal for packaging seeds, fertilizers, and animal feed where robust machinery is essential.
- Food Processing – Suitable for bulk packing of sugar, rice, pulses, and flour, ensuring hygienic and accurate filling.
- Construction Materials – Widely used for sand, cement, dry mix mortar, and wall putty packaging.
Benefits of Choosing a Gross Weighing Machine
- Space Efficiency – Requires significantly less height (headroom) than net weighers since there is no intermediate weigh hopper.
- Cost-Effective Solution – Generally involves lower capital investment, making it an excellent choice for operations with moderate speed requirements.
- Gentle Material Handling – Direct filling reduces product degradation as the material drops only once into the bag.
- Ease of Cleaning – The simple material path allows for quick cleaning and changeover between different products.
