NJP-800C Powder Capsule Filling Machine
Configure automatic hard-capsule production around powder flow, bulk density, target fill weight, accepted output, cleaning and FAT evidence—not rated speed alone.
Final performance depends on approved capsules, powder, tooling, settings, sampling method and acceptance conditions.

Is the NJP-800C the right powder capsule filling machine?
A powder capsule filler separates empty hard capsules, meters a configured powder dose into each body, closes the capsule and discharges it for downstream handling. The correct machine is determined by the powder and acceptance window—not by capsule size and rated output alone.
Strong starting fit
- Hard-capsule powder projects within the published 00#–5# and safety A–E size range.
- Production that needs one automatic cycle for feeding, separation, dosing, rejection, closing and discharge.
- Powder, pellet or tablet projects whose required dosing route is confirmed before quotation.
- Buyers able to provide representative formulation and capsule samples for testing.
Confirm before selection
- Powder flow, bulk and tapped density, particle-size distribution, moisture and static behavior.
- Target fill weight, accepted variation, sampling plan and label-claim boundary.
- Required accepted output after stops, rejects, replenishment and downstream limits.
- Dust extraction, cleaning, containment and cross-contamination controls.
- Documentation, FAT evidence and line interfaces required by the buyer.
FlowBridging, rat-holing and inconsistent powder-bed feed can change the dose.
DensityBulk density and compaction affect the dose available for a selected capsule.
MoistureHumidity response can change flow, sticking and cleaning behavior.
SegregationParticle-size or density differences may require a controlled handling plan.
Prove the dosing window with representative powder
The product source describes multi-bore dosing with a published precision around ±3.5% and a capsule qualified rate above 99%. Those values are machine references; the result for a real formulation must be tested under an agreed method.
Trial inputs
- Representative production powder and capsule lot.
- Target fill weight and permitted variation.
- Dosing-disc and tamping configuration.
- Sampling frequency, test method and run duration.
- Definition of accepted capsule and reject reason.
Engineering rule: if the production formulation cannot be shipped, agree a placebo that reproduces the relevant density, flow, compaction and moisture behavior. A visually similar powder is not automatically a valid substitute.
How the NJP-800C powder capsule filler works
The NJP-800C uses an intermittent-motion cycle. Capsule handling and powder dosing are coordinated through separate stations, while the approved product settings and acceptance limits remain specific to the buyer's formulation.
Feed and orientEmpty capsules enter the machine and are aligned for the selected size parts.
Separate cap and bodyVacuum separates capsule bodies from caps before the dosing step.
Meter powderThe configured multi-bore dosing system meters the qualified powder into capsule bodies.
Reject faultsCapsules not handled as specified are removed according to the configured reject logic.
Close and dischargeCapsule caps and bodies are joined, then discharged for polishing or inspection.
Clean station boresCompressed air and the dust-collection route support removal of residual powder from the cycle.

The values below come from the NJP-800C product source. The quotation and FAT protocol should record the selected configuration and the conditions used to verify performance.
| Item | Published NJP-800C data | Buyer verification |
|---|---|---|
| Maximum output | 48,000 capsules/hour | Define required accepted output and run conditions. |
| Capsule range | 00#–5#; safety capsule A–E | Send physical capsules and supplier references. |
| Dosing type | Powder; pellet/tablet route optional | Confirm formulation and selected dosing system. |
| Published dosing precision | Around ±3.5% | Agree product, dose, sample plan and calculation method. |
| Published qualified rate | Above 99% | Define accepted capsule and reject categories. |
| Electrical supply | 380 V, 50 Hz, 5.05 kW; alternative supply optional | State site voltage, frequency and isolation. |
| Noise index | <75 dBA | Agree measurement point and operating condition. |
| Machine dimensions | 930 × 740 × 1930 mm | Confirm access route and service clearance. |
| Net weight | 800 kg | Check floor loading and handling method. |
| Control | Computer/PLC control with frequency-conversion speed regulation | Confirm HMI language, records and required access levels. |
| Material protection | Automatic pause when capsules or filling material are insufficient | Include the relevant alarm challenge in FAT. |
| Base source package | One 0# change-part set, dust collector, PLC and touchscreen | Replace with the final size and itemized scope. |
Published figures are engineering references, not universal guarantees. Approved powder, capsules, tooling, settings and test conditions control the final result.
Controls, change parts and optional line equipment
Control and mechanical references
The source lists computer/PLC control, stepless frequency-conversion regulation, a lubricated working-station cam and imported linear-bearing references. Confirm the final approved component list and acceptable equivalents before purchase.
Enclosed station design
The product source describes fully enclosed stations rather than the open dosing-station arrangement used by some machines. The buyer must still define dust extraction, room pressure, operator protection and cleaning evidence for the actual powder.
Extra capsule change partsEach additional capsule size requires the corresponding approved parts and setup record.
Capsule polishing and sortingDefine the physical interface, dust collection and acceptance responsibility.
Vacuum powder feedingConfirm powder suitability, feed rate, cleaning and containment boundary.
Empty-capsule loadingConfirm hopper interface, refill method and low-level response.
Metal detectionSpecify sensitivity, test pieces, reject confirmation and record requirements.
Pellet or tablet routeTreat combination fills as a separately tested dosing configuration.
Line boundary: polishing, metal detection, counting, blister packing and cartoning can limit accepted output even when the capsule filler itself is running.
What to send for a useful NJP-800C proposal
The direct source quotation dated June 4, 2025 listed a base NJP-800C package at RMB 124,200 FOB China. Its validity was one month, so it is historical evidence—not a current offer. Request a new itemized quotation for the actual capsule, tooling, options and service scope.

Powder capsule filling machine FAQ
What is the maximum output of the NJP-800C?
The published maximum is 48,000 capsules per hour. Sustained accepted output depends on powder behavior, capsule quality, settings, inspections, replenishment and downstream conditions.
Which capsule sizes can the NJP-800C handle?
The published range is 00# through 5#, plus safety capsule sizes A–E. Each size requires the applicable change parts, and physical capsules should be approved before tooling is finalized.
What filling accuracy can a powder capsule filler achieve?
The NJP-800C source gives a dosing reference around ±3.5%. The actual result must be verified using an agreed powder, fill weight, sampling plan, run condition and acceptance method.
Can the NJP-800C fill pellets or tablets?
Pellet and tablet dosing are listed as optional routes. They require a separately defined and tested configuration rather than an assumption that the standard powder setup covers every combination fill.
How much does an NJP-800C powder capsule filling machine cost?
A source quotation dated June 4, 2025 listed RMB 124,200 FOB China for a base package with one 0# change-part set, dust collector, PLC and touchscreen. That quotation expired after one month; obtain a current itemized quote.
How long does cleaning or size changeover take?
There is no universal fixed time. It depends on the powder, containment and cleaning procedure, number of parts, capsule size, operator method and required release evidence. Measure it during the agreed FAT or site procedure.
What should be tested during FAT?
Test capsule handling, powder dosing, accepted output, rejects, alarms, replenishment, restart behavior, cleaning access and downstream interfaces using the agreed samples and protocol.
