30,000TPY Cement Grinding Project
Design Scheme
Raw Material: Sulphoaluminate cement clinker, Portland cement, metakaolin, lime and gypsum
Input Size: <1mm
Moisture: <5%
Equipment: XZM1250 Superfine Mill
Capacity: 30000Tons/Year
Application: The finished product would be used as slurry and filling material.
Project Profile
The cooperation deepens the mutual trust and win-win between us. The new complete set of equipment for anchoring agent production takes centralized control system and can achieve automatic production as well as automatic trouble removal. The operation is quite easy.
Configuration of Production Line
Different from typical configuration, the configuration of production line provided by ZENITH was improved according to customer’s demands. The main machine was XZM1250 superfine mill and the auxiliary machines include spiral conveyor, powder packaging machine and pneumatic conveyor. This configuration totally met the requirement of production technology of anchoring agent.
Technologies of Production
Taking PLC control system and visualized touch-screen operation, the system is highly automatic and the configuration is reasonable.
The first stage:
Feeding system: The raw materials including cement, lime and gypsum stored at separate material bins are sent by feeding equipment to the weighing system.
The second stage:
Weighing system: Different materials are weighed and made to be ingredient in proportion.
The third stage:
Mixing system: The ingredient enters agravic mixing machine to be mixed fully.
The fourth stage:
Grinding system: The mixture is fed into superfine mill for grinding and classification. This is the key step. The main equipment XZM1250 superfine mill can grind the ingredient into superfine powder whose size can be controlled around 1250 meshes.
The fifth stage:
Conveying, packaging and storage system: The finished products are collected by impulse dust collector and enter the storage tank through pneumatic conveying system. And they are transported to other places after being packaged.
Why Chose ZENITH?
1. Integrated Design Scheme
ZENITH offered a more suitable scheme for machine selection and listed the machines. Meanwhile, we analyzed the costs of project and drew design pictures for the customer.
2. PLC Control Sysytem
To achieve high efficiency, low pollution and less labor, we took the PLC control system and the production line is highly automatic.
3. Excellent Service
According to the actual conditions, our team finished the installation of machines and the commissioning of the plant professionally and normatively, which helps save time cost a lot. And during this period, the team organized training and instructions for the workers at the site.
4. After-sales Service
After finishing the project, our colleagues thoroughly checked and tested the function and quality of machines with our customer. Later, our regular services including supply of spare parts, equipment maintenance call-back and revisit of production line was highly praised by our customer.
Technological Advantages
1. High Efficiency
Under same fineness and power, the new grinding curve’s capacity is 40% higher than that of pneumatic mill and mixing mill, two times of that of ball mill. The energy consumption is 30% of that of pneumatic mill.
2. High Fineness
The single-head and multi-head powder separator can be chosen freely. Speed of every rotor of multi-head powder separator can be controlled and the fineness of finished product can be achieved within prescribed standards.
3. Environment Protection
The use of impulse dust remover, muffler and sound-proof room exerts a positive influence on surroundings. The dust emission and noise reduction totally meets the international standard.
4. Low Costs
The grinding roller and ring are made from special material which increases the using effect greatly. The life-expectancy of quick-wear parts is two or three times of that of impact crusher and turbine crusher.
Customer Feedback
After inspecting the production site, the engineers offered a perfect scheme of anchoring agent production line which used the XZM1250 mill as the main equipment and mixing machine, pneumatic conveyor, elevator and feeder as the auxiliary machines. Since operation, the production line has been stable. And the quality and yielding is out of our expectations. ZENITH deserves the reputation!
Extended Reading
Supporting Material --- Anchoring Agent
The support by anchor bolt is a new method used in tunnel of coal mine. It is widely used in mine production. The use of anchor bolt supporting system occupies over 85% mines and presents the understanding advantages. As the main component of anchor bolt supporting system, anchoring agents develop quickly. The anchoring agents can be classified into cement anchoring agent and resin anchoring agent.
