Pigment, a group of materials can dye other subjects, are divided into soluble&insoluble dye and organic&inorganic dye. Dye, a group of materials can dye fiber and other materials, is divided into natural and man-made dye. SIEHE industry gathers rich experience in equipment application and manufacturing and has provides equipment and turnkey projects to lots of international pigment manufacturers, such as Mingsheng, Clariant , BASF and etc. Mixing equipment, core device of dye&pigment complete production line, as well as additional function are chosen according to production process. Pre-mixing device includes: raw materials’ treatment system(unpacking, feeding, smashing, sieving, drying and etc.), raw materials’ transmission system, raw materials’ storage system, batching system, temporary storage system and etc. After-mixing devices includes: finished products transmission system, finished products temporary storage system, finished products before-packing treatment system(sieving, metal detecting and filtering and etc.), finished products packing system, finished products stacking system and etc. SIEHE also provides the steel structure platform, dust collecting system, automatic control system in different levels.

---|---|---|---|
Raw materials treatment system | Unpacking, Feeding | Small bag feeding station, T-bag feeding station, small bag&T-bag feeding station, automatic small bag feeding station and etc. | Choose according to production process. |
Smashing | Al-round smashing machine, micron smashing machine, air flow smashing machine and etc. | Choose according to production process. | |
Sieving, Filtering | Vibration screen, Linear screen、air flow screen and etc. | Choose according to production process. | |
Drying | Spraying dryer、air flow dryer, fluid bed dryer, belt drierand etc. | Choose according to production process. | |
Feeding System | Feeding | Powder:screw feeding, vibration feeding, belt feeding, rotation valve feeding
Liquid: pump or positive delivery(spraying feeding is optional to improve mixing effect) |
Screw feeder can be frequency speed controlled, valve open grade can be controlled. Feeding speed is fast to slow to ensure batching accuracy and improve batching efficiency. |
Weighting | Powder:weighting bin,normally takes use of weight add method, weight loss method
Liquid: metering or weighting meter |
Loading cell takes use of Mettler Toledo products, weightingaccuracy is opted according to requirements(over 0.2%、0.01% or higher)。 | |
Transmission System | Transmission | Meet the transmission requirement among devices
Vacuum charging machine, belt conveyor, basket elevator, screw conveyor, air transmission, pipe and chain conveyor and etc. |
Choose according to capacity, materials, workshop layout and etc. |
Storage System | Storage | Used to store raw materials, finished products, medium products. Normally, storage system includes: raw materials bin, finished products bin, temporary storage bin before mixing, finished product bin after mixing. | 1,Temporary storage bin before mixing and finished product bin after mixing are able to shorten charging and discharging time so that improve usage rate of equipment to reduce raw cost and improve capacity.
2,Storage bin is with anti bridge device which can be closed type. |
Mixing System | Mixing | NautaMixer, horizontal ribbon mixer, horizontal plough mixer, horizontal non-gravity mixer, V-shape mixer, dual-cone mixer, 3D mixer and etc. | 1,Choose according to production process;
2,Optional function: temperature control, pressure control, non-standard control and etc. |
Packing System | Packing | Open-top packer,valve bag packer, T bag packer | Choose according to packing specifications, accuracy requirement, packing efficiency, material characteristics and etc. |
Electrical Control System | Process Supervising | Electric control building: relay, PLC, PC-based and etc.
HMI:press button type., digital type and etc. CMCC control center,IMCC control center,industry wireless technology(to be developed) and etc. |
Choose according to control complexity, importance of production data, customers requirements of modern and intelligent level. |
Dust Collecting System | Dust Collecting | Filter-element filter, bag-type filter are optional to remit or remove dust. | Choose filtration area and type according to dust area, dust quality, materials characteristics. |
Steel structure Platform | Operation Platform | SIEHE provides necessary steel structure platform of installation, operation and maintenance. | Sectional design is easy to transmission and installation
Extra-heavy structure ensures stability and operators security. |
Materials | Anti-corrosion and easy to clean | SUS304,SUS316L,inside and outside are mirror polished | Choose according to required materials and materials characteristics |
