An integrated complete calcium carbonate filler masterbatch production line mainly includes a full set of equipment for the entire process: “raw material pretreatment – mixing – melting and plasticizing – extrusion granulation – cooling and screening – finished product storage”. It does not include raw material, labor and site costs. The price mainly depends on production capacity, equipment configuration (single-screw/twin-screw), degree of automation, brand and additional services. Based on the current market quotes (February 2026), this report decomposes the price composition and influencing factors by production capacity in US Dollars. All prices have been converted at a rate of 1 Chinese Yuan ≈ 0.138 US Dollars, with reasonable ranges retained to ensure that the data is consistent with the actual market situation.
I. Core Price Ranges by Production Capacity
The production capacity of the production line directly determines the equipment specifications and is the core factor leading to price differences. Combined with mainstream industrial configurations, it is divided into three grades: small-scale, medium-scale and large-scale. The following are all quotes for “integrated complete production lines” (including all core and auxiliary equipment, excluding transportation and installation).
(I) Small-Scale Production Line (Capacity: 100-500kg/h)
Application Scenario: Start-up enterprises and small processing plants, focusing on the production of calcium carbonate masterbatch with low filling ratio (≤40%), mainly with basic configuration to meet the needs of small-batch production.
Core Configuration: Single-screw extruder (diameter 50-75mm) + small high-speed mixer + screw feeder + air-cooled pelletizing system + simple vibrating screen + small finished product silo + basic control system (manual/semi-automatic).
Price Range: 15,000 – 30,000 US Dollars
Price Description: The core equipment is mainly basic brands from China. The single-screw extruder accounts for about 60% of the price (9,000-18,000 US Dollars), and auxiliary equipment (high-speed mixer, feeder, etc.) accounts for 40%. Some manufacturers can provide simple customization, such as adding raw material drying function, and the price can be increased by 10%-15% (1,500-4,500 US Dollars). Referring to quotes from China, the basic configuration of a single-screw production line is 100,000-220,000 Chinese Yuan, which corresponds to this range after conversion.
(II) Medium-Scale Production Line (Capacity: 500-2000kg/h)
Application Scenario: Large-scale production enterprises, focusing on the production of calcium carbonate masterbatch with medium and high filling ratio (40%-85%), compatible with various raw materials such as PE and PP, with medium degree of automation, balancing efficiency and cost performance.
Core Configuration: Twin-screw extruder (diameter 75-110mm, length-diameter ratio 30-40:1) + automatic loss-in-weight feeder + large high-speed mixer (75-110L) + water ring pelletizing/air-cooled die-face hot cutting system + multi-stage cyclone separator + high-precision vibrating screen + finished product silo + PLC control system (semi-automatic, capable of parameter linkage).
Price Range: 50,000 – 120,000 US Dollars
Price Description: The core equipment is the twin-screw extruder, accounting for about 55%-65% of the price (27,500-78,000 US Dollars). It has strong mixing capacity and stable output, making it the core cost source of the medium-scale production line; auxiliary equipment such as automatic feeding and multi-stage separation accounts for 35%-45%. Quotes from Chinese brands are 350,000-880,000 Chinese Yuan, and international mid-range brands are 30%-50% higher than this. For example, the Bengbu Jiade JD75D twin-screw production line is 458,800 Chinese Yuan, equivalent to about 63,300 US Dollars after conversion, which is at the low end of this range; the production line equipped with a 110L internal mixer is 659,000 Chinese Yuan, equivalent to about 91,000 US Dollars after conversion.
(III) Large-Scale Production Line (Capacity: above 2000kg/h)
Application Scenario: Large chemical and plastic enterprises, focusing on the production of calcium carbonate masterbatch with high filling ratio (≥85%), fully automatic production, suitable for continuous and large-batch production needs, and can be equipped with raw material pretreatment (calcium carbonate surface activation) equipment.
Core Configuration: Large twin-screw extruder (diameter 110-180mm, length-diameter ratio 40-52:1) + automatic batching system + high-speed mixer + raw material activation treatment equipment + precision extrusion die + automatic pelletizing and cooling system + online detection equipment + automatic storage and packaging system + intelligent PLC control system (fully automatic, remotely monitorable).
Price Range: 150,000 – 350,000 US Dollars
Price Description: Core equipment accounts for about 60%-70% of the price (90,000-245,000 US Dollars), among which large twin-screw extruders, raw material activation equipment and intelligent control systems are the main costs; fully automatic auxiliary equipment (batching, packaging, storage) accounts for 30%-40%. Quotes from high-end Chinese brands are 1.1 million-2.55 million Chinese Yuan, and quotes from international brands (such as German and Italian equipment) can reach 300,000-500,000 US Dollars. The main gap lies in equipment precision, energy consumption and stability.
II. Key Additional Factors Affecting Prices (in US Dollars)
The above prices are the bare machine prices of the production line (equipment only). In actual procurement, the following factors will lead to an increase in the total price, which need to be focused on:
(I) Equipment Configuration Upgrade
1. Replacing single-screw with twin-screw: Under the same production capacity, a twin-screw extruder is 30,000-80,000 US Dollars more expensive than a single-screw extruder (especially obvious for medium-scale production lines), because it has stronger mixing capacity, is suitable for high filling needs, and has better self-cleaning performance and particle quality;
2. Automation upgrade: Upgrading from semi-automatic to fully automatic (such as batching, packaging, parameter monitoring), the price increases by 20%-40%. A medium-scale production line needs an additional 10,000-48,000 US Dollars, and a large-scale production line needs an additional 30,000-140,000 US Dollars;
3. Core component upgrade: Using corrosion-resistant and high-hardness materials (such as 38CrMoALA nitriding treatment) for screws and barrels, the price increases by 15%-25%; adding online detection equipment (such as particle size detection) adds an additional 8,000-20,000 US Dollars.
(II) Brand Differences
1. Chinese brands: Low price and high cost performance. The prices of the above grades are all based on mainstream Chinese brands (such as Bengbu Jiade and Jiulongde Machinery). The equipment warranty is 1 year, and the core component warranty is 6 months;
2. International brands (such as Germany’s Coperion and Italy’s COIA): The price is 50%-100% higher than that of Chinese brands. The price of a medium-scale production line can reach 75,000-240,000 US Dollars, and the price of a large-scale production line can reach 225,000-700,000 US Dollars. The advantages lie in high equipment precision, low energy consumption, long service life (5-10 years) and longer warranty period (2-3 years).
(III) Additional Services
1. Transportation costs: According to the transportation distance, domestic transportation (to the port) is about 1,000-3,000 US Dollars, and international maritime transportation (to Europe and the United States) is about 5,000-15,000 US Dollars. Due to the large volume of equipment for large-scale production lines, the transportation cost can be increased to 20,000 US Dollars;
2. Installation and commissioning: Installation and commissioning by a Chinese team costs about 5%-8% of the total equipment price, and by an international team about 10%-15%. For a medium-scale production line, domestic installation costs 2,500-9,600 US Dollars, and international installation costs 5,000-18,000 US Dollars;
3. After-sales service and training: Extending the warranty to 2-3 years increases the cost by 10%-15%; providing technical training and lifelong maintenance adds an additional 3,000-10,000 US Dollars;
4. Spare parts package: Purchasing a full set of vulnerable spare parts (such as hot cutting blades and oil seals) costs about 3%-5% of the total equipment price, and about 1,500-6,000 US Dollars for a medium-scale production line.
(IV) Other Factors
1. Customization needs: Such as adapting to special raw materials (such as nano-calcium carbonate) and adjusting the production line layout, the price increases by 10%-30%;
2. Bulk purchase: Purchasing 2 sets or more can enjoy a 10%-15% discount;
3. Exchange rate fluctuations: The current exchange rate is 1 Chinese Yuan ≈ 0.138 US Dollars. Exchange rate fluctuations will directly affect the final US Dollar quote. It is recommended to lock the exchange rate during procurement.
III. Price Summary and Procurement Suggestions
1. Limited budget and small-batch production: Choose a small-scale production line (15,000-30,000 US Dollars), basic Chinese brands, single-screw configuration to meet low-filling production needs. Unnecessary automatic functions can be omitted to control costs;
2. Large-scale production and balanced cost performance: Choose a medium-scale production line (50,000-120,000 US Dollars), mainstream Chinese brands, twin-screw configuration, semi-automatic control. Core components can be upgraded according to needs to balance efficiency and cost, suitable for medium and high-filling ratio production;
3. Large-batch and high-demand production: Choose a large-scale production line (150,000-350,000 US Dollars), give priority to high-end Chinese brands or international mid-range brands, fully automatic configuration, equipped with raw material activation equipment to ensure production efficiency and product quality; if high requirements are placed on equipment precision and stability, international high-end brands (price above 300,000 US Dollars) can be selected.
