45 × 60 Cm Filling Spout Nickel Sulfate FIBC Bag With 45 × 45 Cm Discharge Spout

Ø45 × 60 cm Filling Spout Nickel Sulfate FIBC Bag with Ø45 × 45 cm Discharge Spout

Filling and Discharge Efficiency Depends on Equipment Compatibility

A powder FIBC must do more than contain the material. It must also match the filling equipment, closure method, and downstream discharge system.

A filling spout that does not match the filling pipe can make connection difficult, allow dust to escape, or affect bag positioning. A discharge spout that does not match the receiving hopper may result in unsuitable flow, powder bridging, or material accumulation around the interface.

This nickel sulfate FIBC has a Ø45 × 60 cm top filling spout and a Ø45 × 45 cm bottom discharge spout. The Ø45 cm measurement indicates the spout diameter, while 60 cm and 45 cm indicate the filling- and discharge-spout lengths.

Why the Ø45 × 60 cm Filling Spout Matters

Filling-Equipment Connection

The Ø45 cm filling spout can be connected to a filling pipe, sleeve, or material-feeding outlet of a compatible size. Before production, compare the equipment outlet diameter with the effective internal diameter of the spout and allow sufficient space for overlapping, clamping, or tying.

If the spout is substantially larger than the equipment outlet, additional clamping or dust-control components may be required. If it is too small, it may not fit over the outlet or may remain under tension during filling.

60 cm Length for Connection and Closure

The 60 cm spout length provides working space for equipment connection, fixing, and closure after filling. The current configuration also includes a 25 cm filling-spout tie.

Confirm:

• The required overlap between the spout and equipment outlet;
• Whether a tie, clamp, or another closing method is used;
• Whether a dust-extraction connection is required;
• Whether the filling spout must be reopened;
• Whether the PE liner requires separate tying or heat sealing.

The 60 cm length does not guarantee direct compatibility with every filling system. The effective connection length must be checked against the actual equipment.

Bag Positioning During Filling

The filling outlet should be aligned as closely as possible with the center of the bag. After connection, the pipe should not pull the top structure toward one side, as this can cause bag leaning or off-center material accumulation.

For continuous or high-rate filling, material flow, air displacement, and dust collection should also be confirmed. Spout dimensions do not replace filling-rate control or extraction equipment.

Why the Ø45 × 45 cm Discharge Spout Matters

Discharge Rate and Powder Flowability

The Ø45 cm discharge spout provides an outlet path from the bag bottom. Its diameter affects the available flow area, but the actual discharge rate cannot be determined from diameter alone.

Discharge performance also depends on:

• Nickel sulfate particle size and bulk density;
• Moisture condition, agglomeration, or bridging tendency;
• Compaction of the material inside the bag;
• The method used to open the outlet;
• The capacity of the downstream receiving equipment.

A material with limited flowability may still require vibration, bag massage, or another assisted-discharge method.

45 cm Length for Controlled Discharge

The discharge spout is 45 cm long and includes a 15 cm tie. Before opening, the outlet can be positioned inside or connected to the receiving hopper or pipe. The closure can then be released progressively to reduce uncontrolled material release.

If partial discharge is required, confirm whether the spout must be reclosed and whether the liner outlet is connected correctly to the outer discharge spout.

Downstream Equipment Compatibility

The receiving hopper or equipment inlet must accommodate the Ø45 cm outlet and provide space for a tie, clamp, or flexible connector. An inlet that is substantially smaller than the spout may cause material accumulation, while an unsecured connection may increase dust escape around the interface.

Main Specifications

Where This Configuration Fits Best

Production-Line Filling

At the end of a production line, nickel sulfate may enter the FIBC through a filling pipe, screw conveyor, or gravity feeder. The Ø45 × 60 cm filling spout is suitable for processes requiring a flexible bag inlet to be fitted over and secured to the equipment outlet.

A sample bag should be used to confirm the connection diameter, overlap length, filling height, and dust-extraction connection before production.

Temporary Storage After Filling

After filling, the 25 cm tie can be used to secure the filling spout. Whether the PE liner requires separate tying or heat sealing depends on particle size, temporary-storage period, and environmental conditions.

During storage, prevent the filling spout from loosening and avoid continuous compression of the bottom discharge spout against the pallet or floor.

Internal Transfer

Before moving a filled bag from the filling area to a warehouse or loading zone, confirm that both spouts are secured and are not hanging where they could be caught by forks, pallet edges, or the floor.

The spouts should not be used as pulling points for repositioning the filled bag.

Downstream Discharge

Before unloading, position the Ø45 × 45 cm outlet above or inside the receiving hopper and then release the 15 cm tie. For continuous discharge, confirm that the downstream equipment can receive the material without accumulation around the interface.

Equipment Feeding

When the FIBC feeds a mixer, dissolving vessel, or other processing equipment, the discharge-spout dimensions must match the equipment inlet and connecting sleeve. Enclosed feeding systems may also require clamps, flexible connectors, or dust-extraction interfaces.

Spout Dimensions to Confirm Before Production

1. Filling-Equipment Outlet Diameter

Provide the outside diameter, connection length, and interface design of the filling pipe or equipment outlet. The Ø45 cm filling spout requires sufficient overlap and fastening space.

2. Target Filling Rate

Specify the material flow per unit of time and expected filling time per bag. Filling rate affects air displacement, dust movement, and bag positioning.

3. Closure Method

Confirm whether the filling and discharge spouts use ties, clamps, heat sealing, or another method. Also specify whether the PE liner is closed separately.

4. Discharge-Equipment Inlet Dimensions

Provide the inlet diameter, installation height, and connection method of the downstream hopper, pipe, or feeding equipment. Confirm that the Ø45 cm discharge spout can be connected correctly.

5. Powder Flowability

Provide the nickel sulfate particle size, bulk density, moisture condition, and tendency to agglomerate or bridge. These properties directly affect discharge through the Ø45 cm outlet.

6. Dust-Control Requirement

Where the filling or discharge area has defined dust-control requirements, confirm whether an enclosed interface, clamping device, flexible sleeve, venting structure, or external extraction system is required. The coated body and PE liner do not replace equipment-side dust control.
