Dry-mixed mortar refers to the aggregate by dry sieving process (such as quartz sand), inorganic cementitious materials (e.g. cement) and additives (such as polymer) according to a certain proportion after physical mixing to form a granular or powder, shipped to the site in bags or in bulk, then add water after mixing and use directly. The Siehe Industry has rich experience in equipment and production of fine chemical industry, and has provide equipment and construction services for many global well-known enterprises in the field of dry-mixed. The mixing equipment is the center of dry-mixed mortar production complete sets and we will choose different mixer and its additional features according to different technical requirements for a number of well-known global dry mortar production enterprise to provide equipment and project construction services. The mixing uniformity and mixing efficiency directly affects the system capacity; The pre-mixing period equipment including: raw material storage system, batching system and if necessary in the middle storage system, etc.; After mixing period of equipment including: finished product caching system , finished product conveyor system, finished product packing system etc; It also including the steel structure platform, dust removal system if the system need; It will provide different degree of automation of electric control system According to the customer requirement .

System | Function | Equipment | Remark |
---|---|---|---|
Raw material system | Unpacking and feeding | Small bag feeding station, ton bag feeding station, feeding station for both ton bag and small bag, automatic bag feeding station, etc | Optional according to the technical requirement |
Pulverizer | Universal Pulverizer, micro Pulverizer, Air-jet Pulverizer, etc | Optional according to the technical requirement | |
Sieving filtering | Vibration sieving machine, linear sieving machine , airflow sieving machine, etc | Optional according to the technical requirement | |
Dying | Spray drying machine, airflow drying machine, fluidized bed dryer, belt drying machine, etc | Optional according to the technical requirement | |
Batching system | Feeding |
Powder parts: spiral feeding, vibration feeding, belt feeding, rotary valve feeding Liquid feed using pump or pressurized conveying (can use spray to improve the mixing effect)
|
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 parts: weighing bin, generally adopt desiccant method batching, or weight loss method
Liquid measurement, generally uses flowmeter or weighing measurement |
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 transmission between each equipment in the production line
Vacuum feeding machine, belt conveyor, bucket elevator, screw conveyor and pneumatic conveying system, pipe chain conveyor, etc |
According to the capacity design, materials property, factory 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. Silo is with anti-arch device and can also be made as closed type |
Mixing system | Mixing | Double helix cone mixer, horizontal ribbon mixer, horizontal plough mixer, horizontal non-gravity mixing machine, V/double cone mixer, three-dimensional mixing machine etc. | 1, according to the different material and mixing process requirement, equipped with different forms of mixer;
2, optional features: temperature control, pressure control, customized requirements, etc
|
Packing System | Packing | Top-open bag packaging machine, valve bag packing machine, ton bag packaging machine, vertical screw packing machine, automatic belt type small bag packaging machine, etc | According to the packing specification, accuracy requirement, packing efficiency, material properties etc. Choose the most suitable packing machine. |
Electric control system | Production monitoring | Control circuit structures, relay, PLC, PC - -based, etc
HMI: push button type, digital type etc CMCC control center, IMCC control center, industrial wireless technology (still developing) 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. |
