Shandong, China · more than a decade on this equipment
We build horizontal bead mills from 0.5 to 300 litres, plus modified cycloidal drives for conical screw mixers. You choose the wetted metal, we tell you exactly what it costs and why. FOB Qingdao, WhatsApp before and after the order.
01 / Honest catalogue
A supplier who quotes everything is a supplier who checks nothing. Here is where our experience actually sits.
MADE HERE
Lab machines that repeat a formula, and production machines that hold output hour after hour. Disc or rod-pin rotor, dynamic or static separator, water-jacketed chamber, ceramic or stainless flow path.
MADE HERE
The standard catalogue reducer is the weak part of a conical screw mixer. We rework the output bearing, thrust capacity, flange and sealing so the drive survives dense powder and axial load.
NOT FROM US
Pressure vessels and jacketed reactors need a code stamp, a hydrostatic test certificate and an inspector. We are not that factory, and we would rather say so now than argue about it after shipment.
AVAILABLE, NOT FRONT PAGE
The same workshop builds GFJ high-speed up-and-down dispersers (2.2–33 kW, Φ160–350 mm blade) and water-based coating lines, and we will quote them. We are simply not leading with them: on a bead mill our value is the seal and the liner, and we would rather spend the page there.
02 / What actually decides your machine
01 · SEAL
Water-based slurries dry on the seal face and crystallise. That is where cheap bead mills die in month three. We use a double cartridge seal with an oil buffer kept above chamber pressure, and the seal comes out without dismantling the chamber.
02 · METAL
White and near-white products — TiO₂, toothpaste, sunscreen, food, ceramic paste — pick up metal from the chamber and the rotor. If colour or a food spec matters, the flow path goes all-ceramic or PU and we quote it as such.
03 · BEAD
Bead size sets the screen slot, the rotor tip speed and the risk of blocking. 0.1 mm beads need a different separator than 1.5 mm. Tell us the fineness you need and we size the machine from the bead up.
03 / Range
The series share the same rotor, screen and seal vocabulary, so a result you trust at 1 L is a starting point at 20 L rather than a new experiment. Pick the chamber by batch size, then let us argue with you about the seal.
0.5, 1, 5, 10, 20 and 30 L chambers for formula work, colour pastes and small cosmetic or food runs. Stepless or inverter speed control, explosion-proof motor option, built-in self-circulating rotor pump with an external pump loop for viscous feeds.
10 L to 300 L chambers, 80 L/h up through a 72 000 L batch. Rod-pin rotors for nano work, disc rotors for the volume jobs, and the seal and separator choices put in front of you instead of buried in a price.
04 / Material selection
Prices are relative, on the same chamber size. This is the conversation a trading company will not have with you.
| Grade | Where it belongs | Avoid it for | Relative cost |
|---|---|---|---|
| Carbon steel + coating | Industrial pigments, mineral slurries, non-staining fillers where iron is irrelevant. | Anything white, food, pharma, chloride systems. | 1.0× |
| Stainless SS 304 | General water-based work, detergents, neutral pastes, low-chloride fertiliser carriers. | Halogen-containing actives, strong acid or salt streams. | 1.3× |
| Stainless SS 316L | Our default recommendation. Food, cosmetics, most SC fertilisers, mild solvent systems. | Hot chloride, hydrofluoric or strongly abrasive slurries. | 1.6× |
| ZrO₂ ceramic | White and near-white products, toothpaste, TiO₂, sunscreen, ceramic and battery pastes. | Large shock pressure duty and rapid temperature cycling. | 2.2× |
| PU / rubber liner | Low-cost abrasive duty, small cosmetic and food workshops, easy-clean chambers. | Solvent-based coatings and temperatures above 80 °C. | 1.4× |
| Carbide / SiC parts | Rotors, discs and screens in 0.1–0.3 mm bead grinding and very abrasive carriers. | Nothing — but you pay for it, and only need it where wear is real. | 2.8× |
05 / Applications
These are the sectors our machines run in today in China. If yours is one of them, we start from a known setting instead of a guess.
A
LAS and sulphonate pastes, soap slurries, builder slurries. Hygienic 304/316L, low iron, CIP-friendly chamber.
B
TiO₂ dispersion, pigment concentrates, water and solvent systems. Hegnor 4–6, optional Ex-proof motor and panel.
C
Sesame and peanut paste, cocoa liquor, lecithin, vitamin premix in oil. Food-grade 316L, PU or ceramic, no lubricant contact.
D
SC and CS grinds to D50 2–5 µm on abrasive carriers. Ceramic or SiC wear parts, strict outlet temperature control.
06 / Where your money goes
We have spent more than a decade building and repairing this equipment in Shandong. The drawings, the jigs and the service history came forward with us, and the workshop behind them is ours: strong at machining and assembly, and not interested in hiding what a machine is made of.
So we split the work. They build. We decide what should be built, what each choice costs, and we defend the parts that must not be cut.
07 / Ordering
Product, solids content, target fineness, batch or hourly output, grid voltage. WhatsApp or the quote form.
Model, chamber material, bead range, seal cartridge, motor and starter. A written cost breakdown, not a single number.
25–40 days. The machine runs on the bench with water and then with your media before it is allowed into the crate.
Live WhatsApp walkthrough of your machine, nameplate, spare kit and packing. You approve, then the balance.
Fumigation-free crate, lashing photos, packing list and B/L. CIF and DDP to your port on request.
08 / Before you ask
Because the commission would be in your price. We would rather spend that money on the seal faces and tell you the truth about the machine. You get a direct line to the people who specify and build it, and a price you can take apart line by line.
Yes, and we prefer it. Send 3–5 kg. We grind on a lab unit and return the sample with a report: fineness at each pass, current draw, outlet temperature, flow rate, screen used, bead size and the machine we would recommend with its cost breakdown. Solvent-bearing samples must go by sea freight and we will tell you the route before you ship anything.
We do not publish a number, because a RWM-P5 in 304 with a standard seal and a RWM-P5 with a ceramic chamber, carbide pins, an Ex motor and a PLC are the same model name and a very different machine. Send your specification and you will get the breakdown — base, material upgrade, seal grade, drive, spares, packing, inland freight — with each line priced.
Twelve months from bill of lading date against manufacturing defect on the machine. Wear parts — seal faces, screens, rotor pins, O-rings, liners — are covered for three months against defect. Inside the first twelve months, if we confirm a defect, freight both ways is on us.
30 % telegraphic transfer to start the build, 70 % before shipment — and only after your video audit of your own machine. Letter of credit at sight is negotiable on larger orders. For samples and small spare-part orders we take PayPal or a card link so the paperwork is not more expensive than the parts.
Because the chamber is not made in Switzerland and because we do not carry a distributor margin. The parts that decide machine life — seal faces, screen, bearings, motor — we buy to the same specification. Where we save money you will see it listed as a saving, not hidden as a substitution.
You send us the model and the shaft stamp number from the nameplate. We hold chamber liners, rotor pins, bead screens, seal cartridges and O-rings for every machine we ship, and we publish the dimensional drawing of your machine so you can also buy locally. First-year failures of normal wear parts are covered; freight both ways is on us for the first 12 months.
Whatever you confirm at order. Standard is 380–415 V / 50 Hz three-phase; we wind and label for 220, 380, 400, 415, 440, 460, 480 and 660 V at 50 or 60 Hz, and 110/220 V single-phase for lab units. Getting this wrong is the most common avoidable problem in export — we write it on the nameplate and in the packing list twice.
Product, target fineness, and how many litres an hour. That is enough to start — we will ask the rest.
