Heavy Duty Bolus Tablet Press Machine

The Heavy Duty Bolus Tablet Press Machine is a specialized rotary tablet compression machine designed for producing large, high-density tablets, commonly known as bolus tablets. These are primarily used in veterinary applications (e.g., large oral doses for cattle, horses, or other animals), as well as slugging (pre-compression for further processing), naphthalene balls, chemicals, ceramics, or other industrial large-size tablets.

Unlike standard pharmaceutical tablet presses for smaller pills, heavy-duty bolus models handle significantly higher compression forces, larger tablet diameters, and deeper fill depths to create robust, durable tablets from powders or granules.

Key Features

• Robust Construction — Heavy-duty build with square tubular or cast iron body, middle plate, and rigid frame for stability under high pressure; often GMP-compliant with stainless steel contact parts for hygiene and easy cleaning.

• Single-Sided Rotary Design — Typically single-sided (some models offer adaptations), with fewer stations (e.g., 8, 12, or up to 29 in advanced versions) optimized for larger tooling.

• High Compression Capability — Supports 10–12 tons (or up to 100 kN in premium models) of operating pressure, ideal for dense veterinary boluses.

• Special Tooling — Accommodates oversized punches and dies for large tablets; often includes pre-compression features in some variants.

• Safety and Operation — Includes auto-lubrication, dust extraction compatibility, overload protection, and simple controls for precision and reliability.

• Applications — Veterinary bolus production, slugging (pre-compression for double-layer or coated tablets), nutraceuticals, chemicals, detergents, or salt tablets.

Salient Features of Rotary Tablet Press Machine

• Compact GMP Model.

• Suitable for Bolus Tablets, Detergent Tablets and other bigger size tablets.

• “SPECIAL” heavy duty machine structure for bigger size tablets.

• Compression Zone area is totally enclosed with acrylic guard; thus, compression noise is damped to a certain extent and the dust from ambient cannot enter in a compression zone.

• The tablet press shall be capable of generating compaction load up to 10 tons.

• The top and bottom roller shall be designed and mounted in such a manner that top roller is fixed and bottom rollers shall be movable type and capable of, generally, required load, in addition to their rotary motion their assembly shall facilitate up and down to provide cushioning effect on the tablet. this is attained by having spring loaded assembly on the back side

• The rollers are of suitable diameter to cover at least 5-6 punches for providing sufficient dwell time.

• The control knob and adjustable knob provided shall be easily accessible and open able.

• The feed frame shall be such a way that it ensures no spillage or leakage out of it.

• The hopper shall be provided on top with lid to avoid the fine to mix with ambient and contaminate the room air.

• Machine heart i.e turret which is manufactured from Mechanite grade Casting with brinel hardness to ensure long life of the machine, it provide with key slots to accommodate shaped punches. All turret stations are clearly numbered for easy identification.

• There shall be safe locking system for dies to ensure the dies does not pop up during operation.

• Mechanical arrangement for tools charging and fixing shall be incorporated tool changing position will not be under the feed frame zone.

• Centralized Lubrication and independent lubrication point are provided wherever the rotation movement takes place.

• All the parts and accessories shall be accessible, maintainable and replaceable in the defined areas.

• Shall be provided with necessary features like emergency stop to prevent any untoward incident.

• Shall have suitable HP electric motor.

• Hydraulic guage is provided for indicating the pressure provided in the drive area.

• vAll the hydraulic tubes will be fixed properly and ensure that no leakages shall occurs.

• All control and drive mechanism will be firmly mounted and ensure it during vibration of the press.

• All the adjustment features of the press like depth of fill (Dozzer Unit) Ejection Travel (Ejection Cam); Hardness (Pressure Roll Assembly) will be simple mechanism and suitable, firmly mounted.

Pre Compression & Cleaning

Pre-compression is available to expel air trapped within the material in the die and to pre-densify the material prior to passing through the main compression rolls. This feature improves the quality of the product.

Spacious compression zone with acrylic guards gives a convenient access for cleaning purpose. Lower punch scraper seals prevent material passing through the lower punch guides into cam tracks. Ejection of excess powder reduced by proper selection of adjustment cam. Suction needle provided for clear dust particles during compression Process.
