Custom Size Lithium Carbonate FIBC Bag With Configurable Spouts And Baffles

Custom Size Lithium Carbonate FIBC Bag with Configurable Spouts and Baffles

Custom Product Positioning

This Custom Size Lithium Carbonate FIBC Bag is configured according to the lithium carbonate bulk density, filling weight, equipment connections, discharge method and pallet dimensions rather than being limited to one standard bag size.

The existing configuration provides a reference of 108 × 108 × 125 cm dimensions, a 1,000 kg rated load and a 190 g/m² coated body. Configurable items can include:

• Bag length, width and height
• Filling-spout diameter and length
• Discharge-spout diameter and length
• Baffle dimensions and openings
• Loop length and lifting arrangement
• Fabric weight and coating
• Separate liner requirement
• Ties, protective covers and document pockets

Every customized configuration should be recorded in a separate production specification and verified through sample measurement, filling and equipment-connection tests before mass production.

Bag Size Engineering

The target filling weight and actual lithium carbonate bulk density must be established before defining the bag dimensions:

Required effective volume (m³) = target filling weight (kg) ÷ bulk density (kg/m³)

This calculation provides an initial volume reference. Final dimensions must also consider:

• Required headspace after filling
• Height occupied by the filling spout
• Natural material distribution
• Volume occupied by the baffles
• Pallet length and width
• Warehouse or transport-space restrictions
• Maximum permitted filled-bag dimensions

For a fixed pallet, the base dimensions should normally be established first, followed by the bag height required to provide the calculated volume.

Spout Interface Configuration

The filling and discharge spouts should be designed around the customer’s equipment rather than selected only according to the bag capacity.

The standard reference construction includes:

• Filling spout: Φ45 × 60 cm
• Discharge spout: Φ40 × 55 cm
• Spout material: 90 g/m² internally coated PE
• Filling-spout tie: 25 cm
• Discharge-spout tie: 20 cm

Filling-spout data required

• Filling-machine outlet diameter
• Required insertion depth
• Connection method
• Filling speed
• Venting and dust-collection requirements
• Closing method after filling

Discharge-spout data required

• Receiving-station connection diameter
• Lithium carbonate flowability
• Bridging or caking tendency
• Full or partial discharge
• Permitted residual material
• Secondary closure requirement

When the outlet dimensions are changed, the bottom-panel opening, outlet stitching and equipment connection must be reviewed together.

Baffle Layout Development

Internal baffles restrain outward expansion after filling. The standard reference uses four 56 × 100 cm baffles made from 130 g/m² internally coated fabric.

The baffle configuration should consider:

• Target filled-bag profile
• Lithium carbonate bulk density
• Filling direction
• Internal powder-flow path
• Permitted sidewall expansion
• Number and dimensions of baffle openings
• Powder movement during bottom discharge

Openings that are too small may restrict powder distribution, while excessively large openings may reduce the restraining effect. Customized designs should therefore be checked through sample filling and profile measurement.

Structural Confirmation

When the dimensions, spouts or baffles are changed, the complete standard construction cannot automatically be carried over to the customized bag. The following items must be reviewed:

• Body fabric weight
• Fabric tensile strength
• Loop length and sewn-down length
• Loop attachment positions
• Top and bottom panel dimensions
• Baffle attachment positions
• Stitch density
• Target rated load
• Complete-bag testing requirements

The standard reference fabric has a tensile requirement of ≥1,700 N/50 mm, while each lifting loop has a specified tensile requirement of ≥17,000 N. Their suitability should be reconfirmed if the bag dimensions or loading conditions change.

Application

This Lithium Carbonate FIBC Bag is intended for projects where a standard bulk bag cannot directly match the packaging system, such as operations using non-standard pallets, filling outlets with different connection diameters, discharge stations requiring a specific outlet length, warehouses or containers with strict filled-bag dimensional limits, and battery-material production lines requiring defined feeding connections or residual-material control; configuring the body dimensions, filling spout, discharge spout and baffles separately allows the bag to be aligned with the customer’s filling, storage, transportation and unloading process.
