VSI Distributor Plate
Splits the feed evenly to the rotor ports so tips wear at the same rate
What This Casting Does And Why It Matters
The distributor plate sits under the feed tube and divides material between the rotor ports. If it wears unevenly, the ports stop receiving equal feed, the tips wear at different rates and the rotor goes out of balance — a wear problem that shows up as a bearing problem. PangLei casts distributor plates in high chromium and manganese for Barmac type and CV series machines, held finished in stock alongside the tips.
Technical Features
- High chromium white iron or austenitic manganese steel
- Port division geometry reproduced from the original plate
- Cast with the tip set for a complete rotor package
- Dimensional inspection report issued
What You Get That You Would Not Get Elsewhere
Even feed split keeps the tip set wearing at one rate
Protects rotor balance and therefore bearing life
Held in stock with the rest of the rotor package
Cast in high chromium or manganese depending on the feed
The Failures This Part Is Cast To Prevent
- Uneven tip wear traced back to a worn distributor
- Feed bypassing the rotor ports entirely
- Rotor balance problems that keep returning after new tips
- Distributors replaced a cycle behind the tips
Who It Is For
- VSI operators in manufactured sand production
- Aggregate plants running closed circuit VSI
- Rental fleets holding rotor kits
- Dealers supplying VSI wear packages
Application Scenarios
- Manufactured sand production
- Final stage aggregate shaping
- Closed circuit tertiary crushing
- Rotor rebuilds

How This Casting Is Made
Pattern Making
Once drawings are confirmed, pattern making starts immediately in our own pattern shop. Thousands of finished patterns are already on the shelf, so repeat parts skip this step entirely.
Sandbox Making
Casting Process Simulation System (CPSS) is run before the moulds are made. The cavity is kept as solid and as clean as possible so that inclusions have nowhere to start.
Melting And Pouring
Charge materials are bought to a high standard and temperature is controlled through the whole pour to achieve a fine grain structure. Samples are taken to verify the analysis and adjusted if needed, then kept for at least three years for traceability.
Sandbox Opening
Also called casting cleaning. After initial cooling the box is opened, risers and runners are removed and the casting is cleaned. Cooling time is set by casting size, not by the clock.
Heat Treatment
Heating temperature is strictly controlled and castings are spaced in the furnace so they heat uniformly and meet the water fully. Quenching begins within 30 seconds of withdrawal from the oven.
Machining
After rectifying and polishing, castings are machined strictly to drawing for correct fitment. QC then carries out dimensional inspection and issues the dimensional inspection report.
Inspection
Our own physical and chemical laboratory covers spectrometry, hardness, microstructure, dye penetrant and dimensional inspection on site rather than at a third party.
Packing And Delivery
Finished parts are packed on steel pallets for forklift handling, to international standards for road, rail, sea and air transport.

How This Part Compares With The Alternatives
| Compared With | What Changes |
|---|---|
| Replacing tips only | New tips fed unevenly wear unevenly. The distributor is what makes the tip set wear as a set. |
| High chromium versus manganese | High chromium resists the abrasion of clean quarry fines; manganese is chosen where the feed is dirtier. |
| Running a worn distributor to the next shutdown | The cost lands on tips and bearings, both of which are more expensive than the plate. |
If Your Part Is Not Standard
With our own pattern shop, a 3D scanner and Casting Process Simulation System, we work from your drawing, your worn sample, or a scan taken on your site. Material grade, profile and machining are all specified against your machine rather than against a catalogue.
- Reverse engineering from a worn part, with no drawing required
- On-site 3D scanning where the component cannot be removed
- Material grade selected against your feed rather than a default
- Pattern retained afterwards, so repeat orders skip pattern making
Fitting And Getting The Life Out Of It
- Replace the distributor with each tip set
- Check the feed is centred on the distributor after any chute work
- Inspect the rotor ports while the distributor is out
- Confirm rotor balance after reassembly

VSI Distributor Plate Questions
Is the distributor plate part of the rotor kit?
Yes. We supply the complete rotor wear package — tips, distributor, cavity wear plates, upper and lower plates and bolts — so the set wears evenly.
Do you hold these in stock?
Yes, finished VSI parts are held in stock for fast despatch.
Which material?
High chromium for clean abrasive fines, manganese for dirtier feed.
Can you cast one for a machine not listed?
Yes, from the worn plate or drawing, through the pattern shop.
