Sand & Aggregate Batching and Conveying System for Mixing Plants

The aggregates (sand, crushed stone, etc.) in commercial concrete mixing plants are dynamically weighed and conveyed via an integrated batching system. This system combines conveying, weighing, and batching functions, featuring multiple storage bins with discharge hoppers below. A batching belt transports materials to the mixer. A rail system extends along the bins, allowing a shuttle car to slide and distribute materials efficiently. The feeding system includes a feed belt extending above the shuttle car, with a primary feed hopper at the far end. Adjusting the shuttle car's position enables efficient material distribution.

System Service

Hebei Juxin provides customized design and manufacturing of batching/conveying systems for commercial concrete mixing plants.

Applicable Materials

Crushed stone, sand, and other aggregates for concrete mixing plants.

1.Aggregate Batching System

Bin Capacity

Mixing plants: >20m³ per bin (expandable with belt conveyors or underground bins).

Mixing towers: >50m³ per bin.

Batching Station Structures

1)All-steel structure: Ground-level batching, easy maintenance and drainage; requires loaders/belt conveyors for feeding.

2)Steel-concrete hybrid: Underground bins for thermal insulation; supports loaders/bulldozers/trucks for feeding but complicates maintenance.

Storage Hoppers

3–7 hoppers (4 typical), capacity matched to plant output. Pneumatic gates control discharge.

Weighing Methods

Both methods use electronic weighing with ±0.5% dynamic accuracy：

1)Individual weighing: Dedicated weighing hopper under each storage hopper; materials discharged to horizontal belt after measurement.

2)Cumulative weighing: Dynamic measurement via belt-integrated trough with spring baffles.

2.Aggregate Conveying System

Conveying Methods

belt conveyors dominate. Belt type selection based on slope:

≤22°: Flat-surfaced belts

22°–30°:Herringbone shallow-pattern belts

30°–60°: Sidewall belts

Belt Parameters

Widths:650/800/1010/1200mm

Speeds: 1.6/2.0/2.5m/s
