YZJ-7.5&11 oilseed crushing machine
Reduce oilseed size before roasting or hydraulic pressing
The pre-press machine uses source-described spiral crushing to prepare oilseed for the next process stage. On this page, “pre-press” refers to material size reduction before the main hydraulic press rather than a separate oil-extraction claim.





Position in the line
Place crushing after cleaning and before the selected heat route
Hot-press lines can send crushed material to steaming or roasting before hydraulic pressing. A cold-press route may send prepared material directly toward the press when that matches the oilseed and product plan.
Published material range
Verify the required crush result for the actual oilseed
The current page lists rapeseed, soybean, flaxseed, peppercorn, sesame, walnut, and peanut. Feed behavior and output vary with size, shell, hardness, moisture, cleanliness, and the required discharge form.
Material information to provide
- Oilseed type, variety, and representative photos or sample
- Whole, shelled, broken, mixed, or pre-cleaned incoming form
- Moisture, shell content, stones, metal, and other foreign material
- Required particle result for roasting, steaming, or direct pressing
- Daily input and operating-hour plan
Run a material test when the result matters
The source describes broad material suitability but does not publish a particle-size distribution or test conditions. A trial can confirm feed behavior, output form, fines, heating response, and compatibility with the hydraulic press.
Do not select only from the nominal motor rating when the raw material or required grind differs from the source examples.
Published specification
7.5 kW standard and 11 kW optional drive references
The values below reproduce the current product page. The two capacity figures are source-listed references; confirm the material, feed condition, crusher setting, and measurement basis for the quoted machine.
| Parameter | Source-listed value | Project check |
|---|---|---|
| Model | YZJ-7.5&11 | Confirm the exact model designation on the nameplate and quotation. |
| Machine dimensions | 103 x 100 x 75 cm | Confirm the dimension order, hopper height, and service clearances. |
| Machine weight | 174 kg | Confirm shipping weight, lifting points, and foundation requirement. |
| Standard machine power | 7.5 kW | Match the drive to the oilseed and required output. |
| Optional machine power | 11 kW | Confirm motor, drive, electrical, and capacity differences. |
| Working voltage | 380 V | Confirm frequency, phase, control voltage, and destination-country configuration. |
| 7.5 kW capacity reference | 500 kg/hour | Request the test material and discharge specification. |
| 11 kW capacity reference | 750 kg/hour | Verify whether any mechanical components change with the larger motor. |
Capacity is a material-dependent reference
The live page does not state the oilseed, moisture, incoming size, target particle size, feed method, or test duration behind 500 and 750 kg/hour. Use those numbers for initial comparison, then confirm the project basis in writing.
Source-described design
Spiral crushing in a compact standalone machine
The source presents stable operation, low noise, and reduced wear-part maintenance as product advantages. Treat these as qualitative descriptions and request component and service details for the final machine.
Spiral crushing principle
The machine reduces oilseed through its spiral crushing arrangement. Confirm adjustment, discharge form, reverse or clearing procedure, and overload protection.
Standalone process control
A separate crusher can be started, stopped, cleaned, or serviced independently from the roaster and hydraulic press.
Two motor references
The published 7.5 and 11 kW options give a starting point for capacity discussion. Confirm whether the larger drive changes gearing, frame, electrical control, or wear components.
Line integration
Plan feed height, discharge collection, dust control, material transfer, and buffer capacity around the next heating or pressing stage.
Production footage
Review peanut crushing before confirming the layout
The existing workshop video shows the machine processing peanut material. Use the footage to discuss feed behavior, operator position, discharge collection, dust management, guarding, and transfer into the next process stage.
Line balance
Match crushing output to the next process stage
- Compare the real crusher output with steamer or roaster batch demand.
- Provide a controlled buffer if the crusher and next machine run on different cycles.
- Avoid long holding periods when the prepared material condition matters.
- Match the number and barrel size of hydraulic presses to the preparation schedule.
- Size filtration and oil storage for the press section, not for crusher capacity alone.
The crusher output is not finished-oil capacity
The listed kilograms per hour describe material processing at the pre-press machine. Oil output depends on the oilseed, preparation route, hydraulic press capacity, operating schedule, and filtration stage.
Operation planning
Keep feed clean and the crushing load consistent
- Use upstream cleaning and metal-removal controls appropriate to the oilseed.
- Feed at a rate that avoids bridging, overload, or inconsistent discharge.
- Keep hands and tools away from the hopper and crushing chamber during operation.
- Follow the supplied stop, isolation, clearing, and restart procedure.
- Record crusher setting and discharge result for each material recipe.
Maintenance and spares
Inspect wear components before output changes
- Request the crushing-component, bearing, seal, drive, and electrical part numbers.
- Confirm lubrication points, inspection intervals, and acceptable wear limits.
- Keep the hopper, crushing chamber, and discharge path clean between materials.
- Check fasteners, guards, motor mounting, abnormal noise, and vibration.
- Include the recommended startup spares and tools in the quotation review.
