JN750 Planetary Concrete Mixer
This JN750 planetary concrete mixer overview helps buyers review a mid-size planetary pan mixer for precast concrete, concrete products, blocks, pavers and compact batching-plant production. The existing parameter table lists 1250 L feed capacity, 750 L discharge capacity, ?60 mm aggregate-size reference, 44.25 r/min autorotation speed, 12.74 r/min revolution speed, 2?2 mixing blades, 2?1 side scraper blades, 30 kW motor power and about 4500 kg machine weight. Treat these values as model-comparison references, then confirm the current technical sheet, voltage, control scope, discharge arrangement and installation drawing before ordering. For adjacent models, compare this page with the vertical-shaft planetary concrete mixer category.
Feed capacity reference: 1250 L
Discharge capacity reference: 750 L
Motor power reference: 30 kW
Supply options to confirm: 220/380/415/440/480 V; 50/60 Hz
JN750 Planetary Mixer Configuration Checks
Key JN750 configuration points to confirm before quotation
Review the JN750 as a complete mixing system, not only as a model name. Capacity, aggregate size, blade layout, motor package, discharge gate, control cabinet and installation layout should all match the intended production rhythm.
Planetary mixing system: confirm the mixing-arm layout, blade arrangement and scraper coverage inside the pan. The table references 2?2 mixing blades and 2?1 side scraper blades; verify the current drawing for the quoted version.
Mixing pan and wear parts: check liner material, liner thickness, blade material and replacement access. This matters when the mixer handles abrasive aggregates or high-frequency daily production.
Drive system: the table lists 30 kW motor power. Confirm reducer model, coupling, motor protection, lubrication points and whether inverter or soft-start control is included.
Discharge system: confirm discharge-gate type, opening size, actuation method, downstream hopper height and whether the layout matches the batching plant or product line.
Feeding interface: review aggregate inlet, cement inlet, water and additive dosing points, feeding height and whether upstream weighing equipment is included in the quotation.
Control system: confirm the control cabinet scope, safety interlocks, emergency stops, sensors, operation screen and communication interface if the mixer will connect to a batching plant.
Installation structure: compare machine weight, foundation load, service space, maintenance access and lifting conditions before confirming shipment and site preparation.
How to Review the JN750 Mixing Workflow
Use the workflow below to judge whether the JN750 matches the site process:
A JN750 planetary mixer should be reviewed as a full cycle: material feeding, optional dry mixing, water and additive dosing, wet mixing, discharge and cleaning. The table speeds are useful references, but practical output depends on mix design, filling ratio, moisture control and discharge time.
Feeding stage: confirm batching accuracy, aggregate grading, cement supply method, water dosing and additive dosing. Stable upstream batching is required before the mixer can deliver consistent output.
Mixing stage: check recommended mixing time for the target concrete, blade and scraper coverage, pan filling rate and whether the mixer is intended for dry-cast, wet concrete, precast or concrete product mixes.
Discharge and cleaning stage: confirm discharge time, gate sealing, residual material control, cleaning access and safe lockout procedure. These details affect daily output and maintenance workload.
JN750 Planetary Mixer Buyer Checklist
Capacity match: confirm whether 750 L discharge capacity fits the required batch size and downstream production rhythm.
Application fit: define whether the mixer will serve precast components, blocks, pavers, batching-plant production, test production or specialty concrete.
Mix quality: request recommended mixing time, uniformity expectations and moisture-control assumptions for the planned mix design.
Power and controls: confirm voltage, frequency, motor protection, control cabinet, safety interlocks and automation interface before comparing quotations.
Wear and maintenance: request the liner, blade, scraper, seal and lubrication parts list, together with recommended inspection intervals.
Operation support: confirm manuals, wiring diagrams, spare-parts drawings, commissioning guidance and operator training scope.
Layout planning: check foundation drawing, service clearance, feeding height, discharge direction and lifting access for the installation site.
Quotation clarity: ask which items are standard, which are optional, and whether packing, spare parts, installation support and plant integration are included.

Parameter note: the existing table keeps the original JN750 model values for feed capacity, discharge capacity, aggregate-size limit, autorotation speed, revolution speed, blade arrangement, scraper arrangement, motor power and machine weight. Use these entries for model comparison only. Confirm the current technical sheet, voltage, discharge-gate design, control-system scope, foundation drawing and spare-parts list before ordering.
JN750 Planetary Concrete Mixer: Buyer Questions
When is the JN750 planetary concrete mixer a good fit?
JN750 is commonly reviewed when buyers need a mid-size planetary mixer for precast concrete, concrete products, blocks, pavers or batching lines that require stronger mixing uniformity than simple drum-style mixing.
Which capacity value should buyers compare?
Use both entries together: the table lists 1250 L feed capacity and 750 L discharge capacity. Real production also depends on batching speed, mixing time, discharge time, moisture control and downstream equipment.
What should be checked beyond the 30 kW motor reference?
Check reducer configuration, blade and scraper layout, liner material, control cabinet, safety interlocks, lubrication system, voltage, frequency and whether plant communication is required.
What information helps prepare an accurate JN750 quotation?
Share the concrete type, target batch volume, aggregate size, power standard, feeding method, discharge direction, available space, automation requirements, spare-parts expectation and destination country.
