Research by experts found that the use of concrete with limestone powder in construction can reduce cement dosage, enhance the concrete quality, and improve the construction project quality.  As the scrap material generated from the production of broken stone and stone chips, limestone powder can be used as concrete admixture, which can reduce the pollution and resources waste, promote the high added valued utilization of limestone resources. Thus it will become a future hot spot and development trend of concrete industry.

The fineness, particle size distribution, the reaction activity and composition of lime stone powder  directly affect its use and ratio in the concrete, and then influence the key performance indicators, such as the strength, pump, prevent collapse of the concrete. The quality of limestone powder plays a vital role on concrete . Therefore, the grinding equipment with excellent performance is  very important for producing the high quality lime stone powder used for concrete.

ZK machinery, as the most valued grinding equipment overall solution provider, provide the overall solution of lime stone grinding system used for concrete from the raw materials testing to   project acceptance inspection, after-sales one stop service.

1. Raw materials testing

ZK machinery has nearly 30 years professional experience on the study of limestone and other non metallic minerals, to help customers complete the test of raw materials for limestone mineral. According to the latest industry standards, we determine the best grinding solution, make the fineness, index of activity, fluidity ratio, water content,  calcium carbonate content and other values of limestone powder conform to the provisions of the industry.

2. Project Establishment

ZK machinery has rich experience in project evaluation, familiar with the establishment of powder plant expansion, new construction, reconstruction and other projects. According to the raw materials, site environment, cost and income, etc., ZK provides customers with the feasibility report, the EIA report, the assessment report and other documents to help customers complete the project establishment.

3. Survey and design

ZK machinery has a leading technical service team, with professional technology covering the entire process chain of limestone powder. Based on the investigation and planning, ZK provides customers with the detailed project design plan, the best equipment mode selection, equipment list,  project cost, the basic drawings of project site, also can design the technology and process according to customer's special requirements.

4. Equipment production

ZK machinery has a large-scale equipment manufacturing base of 300, 000 square meters, over 150 sets of various advanced production and processing equipment, and their own machine processing workshop, electrical workshop, machine workshop. Advanced processing technology and quality assurance solve the trouble of the customer's equipment failure, while the leading procurement and inventory, production planning control management ensure the processing quality of the whole set of equipment.

MTW European version mill for the preparation of the limestone powder concrete enjoy the   biggest pendulum mill leading position, while the exclusive use of thin oil lubrication is the best alternative products for the updating of traditional Raymond mill, pendulum mill. LM vertical roller mill set crushing, drying, grinding, grading, transportation in one, which is the first choice of large non-metallic mineral powder device.

5. Installation and commissioning

ZK machinery has a high level, professional, experienced installation team. The whole process is completed by ZK technical team from site planning scheme to the installation of main engine and auxiliary engine. Professional team technical level and high work efficiency can greatly reduce the project period, save time for customers and achieve maximum production efficiency.

6. Training guidance

ZK machinery has a perfect equipment, technology training and guidance system. After installation and commissioning, our professional engineer will visit the site, provide the operation and maintenance measures for the operators, give the instructions of the common questions and ensure the stable operation of the system.

7. Project Acceptance

ZK machinery and customers jointly develop "Project Results Review Plan" and "Acceptance Test Plan", setting up a special inspection coordination group, arranging the company's professional project manager to assist customers the complete inspection on the delivery of product function and quality, solving the problem timely during the customer acceptance process, until the customer is completely satisfied.

8. After - sale service

The delivery of the equipment and the completion of the acceptance is not the end of the service, but the beginning of the service. ZK machinery pay attention on the field of grinding machine for 30 years, with a modern, information-based management system and professional after-sales service team.
