MMJM Rotary Rice Grader
The MMJM(X) rotary rice grader shifts milled rice accurately into head rice, large broken, medium broken and small broken, and it separates other similar grains as well.
What This Machine Does
The MMJM(X) rotary rice grader shifts milled rice accurately into head rice, large broken, medium broken and small broken, and it separates other similar grains as well. It uses a cardan joint connecting rack with a suspender and a non eccentricity transmission device, and the sieve parameters increase the grading area.
Key Benefits
- Classifies milled rice into four fractions in one pass
- Increased grading area through the sieve parameter design
- Cardan joint connecting rack with non eccentricity transmission for smooth running
- Compact construction that is simple to operate
- Capacity from 5 to 13 t/h across four models
Problems It Solves
- Head rice and broken leaving together and being paid at the lower grade
- No measurement point to tell whether an upstream change worked
- Grading machines that run roughly and shake the building
- Limited grading area restricting capacity
Who It Is For
- Rice mills selling graded rice
- Processors separating broken rice as a product in its own right
- Plants checking milling performance daily
- Line builders completing a modern rice mill
Application Scenarios
- Grading milled rice before colour sorting and packing
- Separating head rice from broken for different market grades
- Grading other similar grains in a processing plant
- Quality checking the effect of upstream settings
Technical Features
- Cardan joint connecting rack and suspender with non eccentricity transmission
- Special sieve parameters that increase grading area and improve product fineness
- Material graded while rotating with friction against the sieve
- Leveling device with suction pipe that also lowers product temperature
- Power from 1.5 kW to 3.0 kW depending on model
MMJM Rotary Rice Grader Model Table
Figures below are taken from the TITAN model sheets. Where a figure depends on the crop or the contamination level it is stated that way rather than averaged.
| Model | Capacity | Power | Air volume | Weight |
|---|---|---|---|---|
| MMJM(X)160 x 4 | 5 to 6.5 t/h | 1.5 kW | 800 m3/h | 1560 kg |
| MMJM(X)160 x (4+1) | 5 to 6.5 t/h | 1.5 kW | 800 m3/h | 1660 kg |
| MMJM(X)160 x (5+1) | 8 to 10 t/h | 2.2 kW | 900 m3/h | 2000 kg |
| MMJM(X)200 x (5+1) | 10 to 13 t/h | 3.0 kW | 900 m3/h | 2340 kg |
How This Machine Is Built
Quality Control
- Suspension and drive balance checked on the assembled machine
- Sieve stack alignment verified
- Grading fractions checked during the run test
Materials And Wear Parts
- Grading sieves supplied as wear parts
Customisation Options
- Sieve configuration for the required fractions
- Model selected from throughput between 5 and 13 t/h
- Outlet arrangement matched to the plant layout
Use Guide
- Feed evenly across the sieve width for a clean separation
- Check the four fractions daily at the same point in the shift
- Clean sieve frames between varieties
- Connect the suction pipe so the product is cooled as it is levelled
How It Compares With The Alternatives
| Vibrating grading sieve | Rotary motion with friction grading increases fineness of the separation. |
|---|---|
| No grading stage | Head rice is sold as head rice instead of being averaged down by broken. |
MMJM Rotary Rice Grader Questions
What fractions does it produce?
Head rice, large broken, medium broken and small broken, and it can be used to separate other similar grains.
How much capacity per machine?
From 5 to 6.5 t/h on the 160 x 4 model up to 10 to 13 t/h on the 200 x (5+1).
Why does the drive matter?
The cardan joint rack with non eccentricity transmission is what keeps the machine running smoothly at speed, which protects both accuracy and the building it stands on.
Does it need aspiration?
800 to 900 m3/h is listed per model, and the suction pipe at the leveling device also lowers product temperature.
Can it grade before colour sorting?
Yes, and that is the usual sequence: grade the fractions, then sort each stream.
