Custom Calcium Chloride Dry Roller Compactor & Granulation Production Line

A dry roller compactor for calcium chloride is the core machinery in a dry salt pelletizing plant, designed to squeeze calcium chloride (CaCl2) powder into dense flakes using high mechanical pressure without adding water or requiring fuel-fired thermal dryers. To handle the strong corrosiveness and quick moisture absorption of calcium salt, this custom configuration features a heavy-duty 304 stainless steel dust cover over the feed inlet and roller chamber, paired with a 304 stainless steel discharge hopper. This setup isolates powder dust, stops airborne corrosion across plant equipment, prevents product bridging, and ensures continuous, low-maintenance production.

1. Key Machines in the Calcium Chloride Production Line
Building an efficient calcium chloride pelletizing plant requires matching the main compactor with the right auxiliary equipment:

A. Core Machinery: Custom Dry Roller Compactor
304 Stainless Steel Dust Cover: Encloses the top feed throat and roller zone. Includes suction ports for connection to a pulse-jet bag filter to keep shop-floor air clean.

Forged Alloy Roller Sleeves: Rollers are made from vacuum-quenched 9Cr2Mo or tungsten carbide alloys (HRC 58–62) to handle continuous salt abrasion.

304 Stainless Steel Discharge Hopper: Smooth, polished internal walls guide compacted sheets directly into the crusher without rusting or sticking.

B. Upstream Material Handling & Mixing Equipment
Stainless Steel Feeder & Hopper: Delivers consistent powder feed rates into the compactor.

Twin-Shaft Continuous Mixer: Blends raw calcium powder evenly with returned fine particles before pressing.

Enclosed Bucket Elevator / Belt Conveyor: Transports material between process stages while shielding hygroscopic salt from room humidity.

C. Downstream Granulation & Packaging Equipment
Flake Crusher & Granule Granulator: Breaks dense compressed sheets into irregular or semi-round granules.

Rotary Screening Machine: Separates target 2–5mm granules from fine powders.

Return Screw Conveyor: Automatically routes undersized fines back to the mixer for 100% material recycling.

Automatic Packaging Machine: Seals finished granules into moisture-proof bags immediately to prevent air exposure and caking.

3. How the Machine Line Operates Step-by-Step
Feeding & Blending: Raw powder and recycled fines are fed by a stainless steel screw conveyor into the twin-shaft mixer for even blending.

Dry Pressing: Material enters the dry roller compactor for calcium chloride through the stainless steel dust cover. High-pressure rollers press the dry powder into dense, hard sheets.

Smooth Discharge: Compacted sheets pass through the 304 stainless steel discharge hopper into the crusher without sticking to the walls.

Crushing & Screening: The crushing unit breaks the sheets, and the rotary screen separates standard 2–5mm granules.

Sealed Bagging: Finished calcium granules drop directly into the automated packaging machine for quick, moisture-proof bagging.

4. Frequently Asked Questions
Q1: Can this production line handle both anhydrous and dihydrate calcium chloride?
Yes. The dry compaction process works with both anhydrous and dihydrate calcium chloride powders, provided raw moisture levels stay within the recommended 2–5% range.

Q2: Why use 304 stainless steel for the dust cover and discharge hopper?
Calcium chloride dust absorbs moisture from the air and rapidly corrodes carbon steel. Using 304 stainless steel for the dust cover and hopper prevents rust flake contamination in finished granules and extends overall machine lifespan.

Q3: What line capacities are available for this equipment setup?
Standard single-line capacities range from 1.0 ton per hour (1 MT/h) to 15.0 tons per hour (15 MT/h). Multiple compactor units can be configured in parallel for larger plant outputs.
