The 1070 Series Impeller Filler is designed to fill valve style bags with high bulk density powder products such as Portland and masonry (plastic) cements, fine ground gypsum, hydrated lime, fly ash, fine ground calcium carbonate, talc, silica flours, insecticides, clay products, stucco containing fine sand only and similar products. The products can contain some sand, but it must not be greater than 150 mesh. Bulk densities should remain greater than 50 pounds per cubic foot.

Product Image

The 2010 Plug-Stack is designed to fill valve style bags with dry abrasive products that would normally cause excessive wear on packers that use a butterfly valve at the product inlet. Typical products include pellet, granular or powder products such as ready mix concrete and cement blends that include aggregate particles larger than sand.

Model 4010 Rapid Flow Impeller Filler is designed to fill valve style bags with high bulk density powder products such as Portland and masonry (plastic) cements, fine ground gypsum, hydrated lime, fly ash, fine ground calcium carbonate, talc, silica flours, insecticides, clay products, stucco and similar products. The products can contain some sand, but it must not be greater than 150 mesh. Bulk densities should remain greater than 50 pounds per cubic foot.

Product Image

The 4189 Compaction Bagger is designed to fill valve type bags by volume rather than weight. Typical products include fibrous or compressible materials such as soils, sawdust, cellulose fiber.

Product Image

The 4190 WeighMaster is designed to fill valve type bags with flaked, granular or powdered products such as spice blend flours, salted meat cures, mustard flours, chemical powders, grout blends, livestock supplements and similar materials.

The 4400 Robotic Valve Bag Placer is designed to automatically place valve bags onto the spout of a valve bag filler. This placer will handle most kraft paper bags and some poly bags.

What is a Valve Bag?

A valve bag is a type of industrial packaging used to store and transport dry bulk products like powders, granules, and other free-flowing materials. Unlike traditional bags, valve bags feature a specially designed valve opening, which allows the bag to be filled efficiently without the need for external sealing methods like stitching or heat sealing. The valve opening self-closes once the bag is filled, minimizing product loss and contamination, which helps create a cleaner working environment.

How Does a Valve Bag Filler Work?

Valve bag fillers are specialized machines designed to accurately fill valve bags with dry bulk materials. The process starts by positioning the bag under the filling spout, where it is securely attached. The filler then uses one of several technologies to fill the bag with a precise amount of product, such as gravity fillers, pneumatic fillers, auger fillers, and impeller fillers.

Once the valve bag is filled, the self-sealing valve closes automatically, keeping the contents securely inside and minimizing product spill or dust emissions.

Types of Valve Bag Fillers

At Chantland-MHS, we offer several types of valve heavy bag fillers to suit different material types and operational needs. Each type is designed to provide efficient, high-speed filling while ensuring accuracy and minimizing material waste:

Auger Fillers

Auger fillers use a horizontal screw to convey powder-like, granular, or flake products into the bag. The auger system provides a controlled flow, ensuring accurate metering of even the most challenging materials. While auger fillers tend to fill bags at a slower rate compared to pneumatic or impeller fillers, they offer high precision, making them ideal for products that require controlled dosing.

Impeller Fillers

Impeller fillers use a vertical or horizontal multi-blade impeller to convey bulk material into the valve bag. The impeller system is highly efficient, moving materials quickly with minimal air entrainment. This results in faster fill rates and smaller-sized bags. Impeller fillers are well-suited for handling powders and granular materials where speed is a key factor in productivity.

Gravity Fillers

Gravity fillers rely on the natural force of gravity to transfer bulk material from a hopper to the valve bag. This is the simplest and most cost-effective method, though it is less efficient than other filler types. Gravity fillers are ideal for less demanding applications where lower filling speeds are acceptable and where a power source is not needed.

Pneumatic Fillers

Pneumatic fillers use compressed air to move material into the bag. This system is efficient for lightweight products such as powders or finely granulated materials. Pneumatic filling ensures even, fast, and accurate packing while reducing the potential for material spillage and dust emissions.

Features and Benefits of Valve Bag Filling Systems

  • Highly Accurate Filling: Our valve bag fillers are equipped with advanced metering technology, ensuring precise weights for each bag. This reduces material waste and ensures consistency across production runs.
  • Improved Efficiency: Automated filling systems maximize speed and minimize downtime, increasing overall productivity.
  • Self-Sealing Bags: Valve bags seal automatically once filled, eliminating the need for additional bag-sealing processes. This reduces the risk of contamination and minimizes handling time.
  • Clean and Safe Work Environment: By containing the material within the valve bag, these fillers reduce dust emissions and spillage, creating a safer and cleaner workplace.
  • Versatility: Our systems handle a variety of materials, including powders, granules, pellets, flakes, and fibrous products, making them suitable for many industries.
  • Low Maintenance and Long Lifespan: Designed for durability, our valve bag fillers require minimal maintenance and offer long-lasting service with high performance.
