Dual‑lane semi‑automatic weigher for powders and granules. Two 25 L hoppers increase throughput; typical speed ≈20–30 bags/min with 100–10000 g fills.
The Lancing model comparison places the published range, speed, accuracy wording and hopper information beside the smaller models while retaining the trial conditions and limitations stated on the current pages.
The range, speed, accuracy and hopper information shown above comes from the supplied source page. Those figures should be confirmed with the real product, target weight, pack format and operating method before the final specification is accepted.
| Published source-page item | Value shown above | Condition to confirm |
|---|---|---|
| Fill range | 100–10000 g | Product density, piece size, hopper loading and outlet arrangement |
| Typical speed | 20–30 bags/min | Target weight, product flow, operator or bagger cycle and discharge timing |
| Typical accuracy | 2–6 g | Product, target weight, feeder settings, sample size and measurement method |
| Hopper arrangement | Two 25 L hoppers | Usable volume for the product, refill method and cleaning access |
Two weighing lanes can support a higher combined output or two coordinated discharges, but the downstream pack handling must be able to receive the doses. Confirm whether lanes run independently, alternately or into separate packs, and how faults or product starvation on one side affect the line.
Record each lane separately as well as the combined line result. Include weight data, giveaway, refill behaviour, operator handling, pack presentation, stops and cleaning or changeover time.
A combined bags-per-minute figure can hide a lane that feeds, weighs or recovers differently from the other. The trial should identify lane-specific results and then confirm how the two lanes behave together through the downstream pack process.
For each lane record target, mean, minimum, maximum, variation, giveaway, rejects, refill behaviour and achieved cycle time. Compare the feeder settings and product level so a difference between lanes can be traced rather than averaged away.
Pause the upstream supply to one lane and confirm whether the other lane continues, slows or is inhibited. The control philosophy should state how an uncompleted dose, a full hopper or a downstream stop is handled.
Define whether the two lanes feed separate packs, alternate into one pack system or discharge into another coordinated process. Verify that the receiving machine can accept the intended sequence without double filling, waiting for a dose or losing pack tracking.
Check access to both product paths, identification of lane-specific parts, residual product, setup confirmation and the first acceptable fills after restart.
Include the product, target weights, pack openings, lane sequence and fault-handling expectations.
