Calcium-Zinc Composite Stabilizer Production Line

Widely used by PVC additive manufacturers, chemical processing plants, and polymer compounding facilities, this production line delivers outstanding batch consistency, production efficiency, and product quality while meeting modern environmental and occupational safety standards.

What Is a Calcium-Zinc Composite Stabilizer?

Calcium-zinc stabilizers are environmentally friendly PVC heat stabilizers that replace traditional lead-based stabilizers. They are widely used in:

Producing high-quality calcium-zinc stabilizers requires accurate ingredient dosing, homogeneous mixing, temperature control, and contamination-free handling. The Rongsheng production line is engineered to achieve these critical requirements.

Key Features of the Calcium-Zinc Composite Stabilizer Production Line

Fully Automated Production

The entire production process is controlled through an advanced PLC automation system. Automatic weighing, feeding, mixing, cooling, and packaging significantly reduce manual intervention and improve production consistency.

Modular Stainless Steel Construction

All material-contact parts are manufactured from high-quality stainless steel, providing:

Vertical Process Design

The production line adopts a vertical process layout:

Raw Material Feeding → Metering → Mixing → Cooling → Storage → Packaging

This design minimizes conveying distance, reduces energy consumption, and lowers the risk of cross-contamination.

Closed-Loop Dust-Free Operation

A fully enclosed conveying and processing system effectively controls dust emissions, creating a safer and cleaner working environment while improving product purity.

Core Equipment and Functions

1. Raw Material Storage and Metering System

The upper section of the production line is equipped with multiple stainless-steel silos for storing:

A high-precision loss-in-weight dosing system automatically meters ingredients according to preset formulations.

Benefits

2. Double-Shaft Paddle Mixing System

The central processing section utilizes a heavy-duty horizontal double-shaft paddle mixer manufactured from SUS304 stainless steel.

Features

The mixing system ensures complete integration of active ingredients and carriers, producing a highly homogeneous stabilizer formulation.

3. Cooling and Temporary Storage System

After thermal mixing, materials are automatically transferred into a cooling storage silo.

The jacketed cooling system rapidly lowers product temperature to below 40°C.

Advantages

4. Automatic Packaging System

The bottom section of the production line includes a fully automatic packaging unit capable of:

Standard Packaging

Optional Packaging

Production Process

Step 1: Raw Material Preparation

Qualified powders and liquid additives are loaded into designated storage silos.

Step 2: Automatic Dosing

The PLC-controlled metering system accurately weighs each component according to the production formula.

Step 3: Thermal Mixing

Materials enter the double-shaft mixer where blending and dispersion occur under controlled temperature and speed conditions.

Step 4: Cooling

The mixed product is transferred to the cooling silo to rapidly reduce temperature and stabilize product properties.

Step 5: Quality Inspection

Samples are tested for:

Step 6: Packaging and Storage

Qualified products are automatically packed and transferred to finished goods storage.
