High-Density Counterweight Sand For Engineering Machinery And Equipment Weight Balancing
Counterweight sand is a granular material used to add mass or balance in machinery, vehicles, and industrial structures. It is not an abrasive. Shandong Haishan Industrial Technology supplies this product for applications that require a dry, free-flowing, and stable ballast material.
The material is produced from selected high-density minerals. It is screened to a consistent particle size and dried to a low moisture content. This allows it to be poured into confined spaces without bridging or caking. Typical uses include elevator counterweights, machine bases, ship ballast, and crane counterweight boxes.
Physical Properties
| Property | Typical Range |
| Bulk Density | 2.5 - 4.5 g/cm³ depending on mineral grade |
| Particle Size | 0.2 - 5.0 mm, screened to customer requirements |
| Moisture Content | ≤ 0.5% after drying |
| Hardness (Mohs) | 5 - 7 for mineral sands |
| Packing | 25 kg bags, 1 ton bulk bags, or loose bulk |
Where It Is Used
- Elevator counterweight filling
- Machine tool bases and vibration damping
- Ship ballast and offshore platform weighting
- Counterweight boxes for cranes and material handling equipment
- Foundry sand for specialized molding where high density is required
Counterweight sand is not suitable for surface preparation. For cleaning, descaling, or profile creation, metal abrasives such as steel shot or steel grit are the correct choice. If a cylindrical abrasive with controlled shape is needed, steel cut wire shot can be considered.
Packing and Storage
Counterweight sand is supplied in moisture-resistant packaging. Standard options include 25 kg multi-wall bags, 1 ton bulk bags, or direct bulk loading into silos or containers. The material should be stored in a dry area to maintain free-flowing properties. When stored correctly, it does not harden or degrade over time.
Inspection and Testing
Each shipment is checked for bulk density, particle size distribution, and moisture content. Samples are taken from each production batch before packing. Material that does not meet the agreed density or size range is rejected before dispatch.
Frequently Asked Questions
Can counterweight sand be used in shot blasting machines?
No, counterweight sand is not an abrasive. It is designed only for adding weight or balance. Using it in a blasting machine would not provide effective cleaning and could damage equipment.
How is counterweight sand different from steel shot?
Steel shot is a spherical metallic abrasive used for surface treatment. Counterweight sand is a mineral-based filler used only to increase mass. It has no cutting or cleaning ability and is not consumed during use in the same way as an abrasive.
What density options are available?
Depending on the mineral type, bulk density ranges from approximately 2.5 to 4.5 g/cm³. Higher densities are achieved by using magnetite or barite. Our team can recommend the most cost-effective grade for your weight requirement and space limitation.
