Product Overview


This integrated rubber products production line is customized for enterprises needing standardized single-stage or multi-stage rubber compound mixing process. Different from traditional scattered manual rubber mixing equipment, this line takes kneader mixer as core processing host, cooperated with automatic multi-ingredient formula weighing system, bucket elevator, rubber open mill and batch-off discharging machine to form a closed-loop mixing production system. Combined with Root’s Blower vacuum conveying structure and screw quantitative weighing structure, the line realizes full automatic material handling from raw material feeding, storage, weighing, dosing, kneading mixing to finished rubber batch-off discharging. 


It supports powder and oil dual independent weighing, with fixed professional weighing range and high dynamic-static weighing precision. The whole system is compatible with 55L to 160L industrial banbury mixers, meets mixing production demand of different rubber viscosity and formula. Besides rubber products, it can also process plastic raw materials, shoe chemical materials, rubber cable materials and industrial chemical filler materials. The system adopts partition design of storage area and production area, supports one-storey and two-storey plant installation, and integrates upstream mixing equipment, banbury mixer and rubber weighing device into one unified control program, achieving full online intelligent control and factory digital information management.


Complete Line Composition


  • Automatic Multi-ingredient Formula Weighing System: Independent powder and oil split weighing module, finish formula automatic batching according to preset production parameters

Product Core Advantages 


  • First, wide banbury compatibility. The whole control system perfectly matches 55L to 160L full-spec industrial banbury mixers, no need to modify original banbury program for matching use. 


  • Second, low factory construction cost. It is flexibly installed on one-storey or two-storey workshop, no need to build high-standard multi-layer special workshop, saving early plant investment. 


  • Third, full-process raw material automatic processing. It independently completes storage, conveyance, weighing and dosing of carbon black, white fillers, rubber processing oil and other core rubber ingredients, reducing manual material contact. 


  • Fourth, standardized workshop partition. Raw material storage area is completely separated from mixing production area, avoiding raw material cross-contamination and optimizing workshop sanitation management. 


  • Fifth, unified online linkage control. Integrate kneader upstream equipment, banbury mixer and rubber weighing scale into one control system, realize synchronous start-stop and fault linkage alarm. 


  • Sixth, intelligent factory management. Realize whole workshop production automation and enterprise production data information management, convenient for production data statistics and formula traceability. 


  • Seventh, multi-industry versatile use. It covers production of rubber finished goods, plastic semi-finished materials, shoe chemical materials, insulation rubber cable materials and industrial chemical compound materials. 


  • Eighth, optimized composite conveying weighing structure. Combine vacuum negative pressure conveying and screw constant-quantity weighing, lower space occupation compared with full vacuum system, and keep high weighing accuracy within ±50g-0.5% to reduce raw material waste.



FAQ 


Q1: What volume of banbury mixer can this kneader production line match?

A1: This line is specially designed for banbury mixer with capacity from 55L to 160L, applicable for medium and large rubber mixing banbury equipment.


Q2: Can this line work in single-layer ordinary factory building?

A2: Yes. It supports both 1-storey and 2-storey plant layout. Its height is only 1-2 meters higher than full vacuum system, no special high workshop space required, saving plant construction cost.


Q3: What rubber raw materials can this automatic weighing system measure?

A3: It can finish automatic weighing and dosing of carbon black, white inorganic fillers, rubber processing oil and other major powder and oil rubber compound ingredients.


Q4: What is the difference between this system and full vacuum rubber mixing system?

A4: This system adopts vacuum conveying + screw hybrid weighing structure. It occupies less workshop space, only 1-2m higher than full vacuum system, and owns higher and more stable weighing accuracy at ±50g to 0.5% error range.


Q5: Can this line produce materials other than rubber products?

A5: Yes. Except various rubber products, it can process plastic compound materials, shoe chemical raw materials, rubber insulation cable materials and industrial chemical mixed materials.


Q6: Does the system support unified online control of all mixing machines?
A6: Sure. The system integrates kneader upstream equipment, banbury mixer and rubber weighing scale into one program, realizing unified online operation, parameter adjustment and fault monitoring.
