A Salt Tablet Press Machine is a specialized industrial equipment designed to compress granulated or powdered salt into uniform, solid tablets or blocks. These machines are essential in industries like water treatment, food processing, and pharmaceuticals, where salt tablets are used for applications such as water softening, dishwashing, animal feed supplements, or effervescent formulations. Unlike standard tablet presses, salt-specific models are built with enhanced corrosion resistance due to salt’s abrasive and corrosive nature, ensuring durability and hygiene. They operate on principles of hydraulic or mechanical pressure to achieve precise tablet dimensions, weight, and hardness.

How It Works
The process is automated and continuous for high-volume production:
-
Material Feeding: Granulated salt powder is fed into the machine’s hopper or cavity, often using a force feeder or bucket-type mechanism to ensure even distribution.
-
Compression: The salt enters a die cavity between upper and lower punches. High-pressure punches compress the material, fusing it into a solid tablet. Hydraulic systems transmit even pressure via static fluid, while rotary models use rotating turrets for multiple stations.
-
Ejection and Output: The formed tablet is ejected from the die, with adjustable settings for thickness (up to 18 mm) and diameter (up to 30 mm). Tablets can be round, geometric, double-layered, or imprinted.
-
Quality Control: Machines include overload protection to prevent damage, automatic lubrication for minimal downtime, and features like stainless steel (SS 316) contact parts to resist rust and contamination.
Key Features
-
Corrosion-Resistant Construction: Dies and surfaces made from anti-rust stainless steel or special alloy steel to withstand salt’s effects.
-
Efficiency and Precision: Double-press rollers for uniform hardness; cGMP-compliant for hygiene standards.
-
Versatility: Suitable for various salt types; some models support annular or two-tone tablets.
-
Safety and Maintenance: Overload auto-shutoff, external parameter adjustments, and waste oil collection systems.
-
Power and Size: Typically 3-5 kW motors; compact rotary designs for R&D or heavy-duty for industrial use.
Applications
-
Water Treatment: Produces compact salt blocks for softening systems, reducing valve maintenance.
-
Household and Industrial Cleaning: Dishwasher salt tablets for efficient dissolution.
-
Food and Animal Nutrition: Licking blocks or sodium supplements.
-
Pharma/Chemical: Custom formulations requiring precise dosing.

Working Principle of Tablet Press Machine
Tablet compression machine basically works on hydraulic pressure. This pressure perform key role in any type of Tablet Machine. It transmitted unreduced through the static fluid. Any external applied pressure is transmitted through static fluid to all directions in the same proposition. which resulting make suitable to increase pressure.
To form a tablet, the granulated powder material must be metered into a cavity formed by two punches and a die, and then the punches must be pressed together with great force to fuse the material together. There are two types of tablet presses called Single Station Tablet Press and Multi Station Tablet Press. Working of these machines differs in terms of production output and feature requirements.
