Refractories Complete Production Line, manufactured by SIEHE Industry, includes six parts: feeding system, conveying system, storage system, batching system, blending system and packing system. The production process is manual feeding, conveying each kind of ingredient into correspondent raw materials hopper through pneumatic conveying device. The quantities of main ingredient and other ingredients are controlled by batching system. The batching system controls the Screw Conveyor and Belt Feeder under the raw material hopper, to add different main and auxiliary materials into the batching tank automatically according to the set value; Then through pneumatic conveying device, the batching tank send the material to the intermediate hopper; Finally, the mixed material will be packed by Automatic Packing Machine and conveyed to the finished product warehouse.

System Components | Function | Optional Equipment | Remarks |
---|---|---|---|
Raw Material Handling System | Unpacking, Feeding | Small bag feeding station, Ton bag feeding station | Optional according to the technical requirement |
Batching System | Feeding | Powder Part: screw feeding, vibrating feeding, belt feeding, rotary valve feeding | Screw frequency control of motor speed, the opening of the valve can be adjusted. Fast feeding first and then slow feeding and feeding speed can be controlled to ensure batching accuracy and also to improve the batching efficiency. |
Weighing | Powder Part: Weighing Hopper, the batching generally used weighing gain method, or can use weighing loss method. | Weighing module using Mettler Toledo products, choose module with different precision (0.2%, 0.01% or more).as per the requirements. | |
Conveying System | Conveying | Meet the requirements of conveying within the equipment in the production line.
Belt Conveyor, Bucket Elevator, Screw Conveyor, Pneumatic Conveying System, etc.. |
Selection according to the capacity design, material property, plant layout, etc.. |
Storage System | Storage | Apply to raw materials and finished products, intermediate storage; There are: raw materials silo, finished product hopper, temporary storage hopper before mixing, finished products hopper after mixing, etc | 1. Temporary storage before mixing, finished product hopper after mixing, can shorten the time of feeding and discharging of the mixer, to improve the utilization ratio of mixer, reduce production cost, improve the system capacity;
2. Storage tank with broken arch (Vibration hammer or fluidistor). |
Mixing System | Mixing | Horizontal Non-gravity Mixer, Horizontal Plough Mixer, etc.. | Select different mixers as per different material property and mixing processing requirements. |
Packing System | Packing | Top Open Bag Packing Machine, Ton Bag Packing Machine, etc.. | Choose the most suitable packing machine by the packing specification, accuracy requirement, packing efficiency, material properties etc. |
Electronic Control System | Monitoring | Control Circuit Built: Relay, PLC, PC-based, etc..
HMI: push button, digital type, etc.. CMCC control center, IMCC control center, industrial wireless technology (in development),etc.. |
According to the complexity of the control, the importance of the production data acquisition as well as the customer’s requirements on modernization intelligent degree, select the most appropriate control system. |
Dust Collecting System | Dust removal | Cartridge dust collector, filter bag dust collector, relieve or clean the dust problem | According to the dust area, dust emission, material features, to select the rational filter area, filter form. |
Steel structure | Operation platform | Provide steel structure equipment installation, equipment operation and maintenance of the platform. | Detachable design, easy to transport and install, more flexible;
Heavy-duty structure, more stable to be safer for the operator. |
