Grand Machinery engineers cGMP-compliant tablet press systems for manufacturers in 50+ countries — from pilot-scale R&D to 600,000-tablets-per-hour production lines. Consistent weight. Repeatable hardness. Lifetime engineering support.
Every Grand Machinery tablet press is engineered around three non-negotiables: uniform tablet weight, repeatable hardness, and fast, validated changeover. These are the three configurations most requested by pharmaceutical, nutraceutical, and industrial buyers worldwide.
Grand’s rotary tablet press runs a precision-machined turret with 19–45 stations, producing 60,000–430,000 tablets per hour on standard B or D tooling. Hydraulic overload protection guards your punches and dies, while the forced feeder keeps low-density granulations filling evenly at high turret speeds. Independent pre- and main-compression stations let you dial in hardness without sacrificing output — keeping weight variation inside ±3% batch after batch.
Best for: Mid- to high-volume pharma, nutraceutical, herbal & chemical granulation.

Every Grand Machinery tablet press machine is assembled, wired, and FAT-tested inside our own facility — no outsourced frames, no third-party control cabinets. Vertical integration means tighter tolerances, faster spare-parts dispatch, and engineers who know your machine by serial number, not just model number. Two decades in, that's an installed base still running three-shift production after 15 years.
A tablet press machine is a 15-year investment — support matters more after delivery than before it. You get 24/7 remote diagnostics, commissioning engineers on-site worldwide, and fast-moving spares stocked for 72-hour dispatch. One dedicated engineer follows your project from spec review through your first validated batch, and answers on the first call — not the third email.
Your auditors will ask. We answer in advance. Each tablet press machine ships with documented IQ/OQ protocols, 3.1 material certificates for every product-contact surface, and a complete cGMP documentation package. Our factory is ISO 9001 certified, and machines carry CE conformity for the European market. Audit-ready traceability is standard — not an option negotiated after the PO.
A tablet press machine forms tablets by compressing a measured volume of granulated powder between an upper punch and a lower punch inside a die. On a rotary machine, this cycle repeats at every turret station, dozens of times per rotation. Master the six steps below and you’ll specify the right machine — and troubleshoot formulation changes faster.
Granulated material flows from the hopper into the forced feed frame, which meters powder into each die cavity as the turret rotates continuously.
The lower punch glides over the weight-adjustment cam to a precise depth, defining fill volume. Servo-driven dosing corrects automatically to hold tablet weight inside tolerance.
A light pre-compression strike expels entrapped air and pre-densifies the powder. This is followed by a main compression stage that locks in target hardness, thickness, and performance.
The lower punch rides up the ejection cam, lifting the finished tablet flush with the die table, clear of the die bore.
A scraper guides tablets into the discharge chute while in-line weight checking and optional metal detection reject out-of-spec product automatically — before it reaches packaging.
Send us your formulation, target output, and tablet dimensions. Within 24 hours you’ll receive a machine recommendation, budget quotation, and tooling options — from an engineering team that builds complete production lines, from granulation to tablet press machine to packaging.
Straight answers to the questions our engineering team hears most from procurement and production managers.
A tablet press machine — also called a tablet compression machine or pill press — converts powder or granules into tablets of uniform weight, hardness, and dimensions. Material is dosed into a die and compacted between two punches. Modern rotary machines repeat this cycle at every turret station under full process control, producing hundreds of thousands of tablets per hour.
Single-punch (eccentric) presses use one die and suit R&D, clinical batches, and small-scale output — typically under 15,000 tablets per hour. Rotary machines carry multiple stations on a rotating turret and start where single-punch capacity ends. If your target exceeds roughly 50,000 tablets per hour, a rotary tablet press machine is the economical choice.
Tooling sets your tablet size and maximum compression force. B tooling runs standard round and small shaped tablets at high speed; D tooling handles larger tablets and forces up to ~100 kN; BB covers extra-large formats. All Grand Machinery machines accept TSM and EU-standard tooling, so punches and dies can be sourced globally without re-machining.
Pharmaceutical granulations, vitamin and nutraceutical blends, herbal extracts, chemicals and catalysts, detergents, fertilizer, and confectionery such as milk tablets and candy. For poorly flowing or low-density formulations, we configure a forced feeder and pre-compression setup matched to your material’s bulk density and compressibility.
Three controls work together: dosing depth sets fill weight, compression force sets hardness, and the closed-loop weight-control system samples output continuously and corrects dosing in real time. Pre-compression removes the trapped air that causes weight drift and splitting. On a well-maintained machine, weight variation holds within ±3% — comfortably inside pharmacopoeial limits.
Every machine ships with IQ/OQ protocol templates, a factory acceptance test (FAT) report, 3.1 material certificates for contact parts, electrical and pneumatic schematics, CE conformity documentation, and an English operation & maintenance manual. On-site SAT and validation support can be arranged.
Standard models ship in 30–45 days ex-works. Every machine carries a 12-month warranty against manufacturing defects, plus lifetime technical support, 72-hour spare-parts dispatch, and 24/7 remote diagnostics. Custom configurations — special materials, local voltage standards, ATEX environments — typically add two to three weeks.
