PREFACE

Green building materials complete solution is Kefid in the "green" guiding ideology, combined with the status quo of the gravel industry put forward a strategic development of a new model for the industry. It covers four business modules: green high-quality gravel system, green dry mortar system, green mine complete system, and overall urban construction waste solution.

Dry mortar system for green building materials complete sets of solutions, mainly supporting high-quality sand system, the use of mine stripping waste rock, urban construction waste, ore dressing plant tailings and other solid waste as raw material, through no dust, low noise, zero by-product emissions of green processing technology to produce high quality gravel aggregate to meet the needs of infrastructure and business development.

BACKGROUND

Most dry mortar companies use natural river sand as aggregate, so the following problems can not be avoided.

Resource depletion. The rapid development of the global economy has resulted in a large amount of river sand being over-exploited and depleted.

Price increases. Decreasing resources and the market demand, will inevitably lead to the price of gravel resources floating too fast.

Environmental difficulties. The use of river sand must increase the drying process, thus using kerosene, natural gas, etc., will add to the natural environment a burden.

Fineness modulus difficult to tune. Fineness of the river sand is often relatively fixed modulus can not be adjusted too coarse or too thin river sand need to be matched before use.

Mud content exceeded. Not only the quality of ready-mixed mortar mortar there is a greater hazard, but also more complicated dust and emissions.

The five major contradictions in the mortar industry are calling for new changes. It is an excellent choice in the new situation to vigorously develop eco-friendly, energy-efficient and eco-friendly dry-mixed mortar.

ADVANTAGES

Investment prospects

Waste recycling can be achieved to produce high-quality gravel, machine-made sand, and further processing of concrete, dry mortar, water stabilizers and other high value-added environmentally friendly building materials.

Freeze-drying, avoid mixing

It not only saves drying equipment and simplifies the process of aggregate ratio, but also reduces harmful gas emissions and saves energy costs.

Environmental protection and efficient

The use of integrated solutions and ladder process, with a high degree of automation, small-scale investment, intelligent and flexible advantages.

EQUIPMENT

VU aggregate optimization system

Kefid's VU aggregate optimization system is a fully-renewed and upgraded dry sand making system based on years of experience in research and development. The highly compact tower-type fully enclosed system combines high efficiency sand making, grain size optimization, stone powder control, gradation adjustment, moisture content control, environmental protection in one, not only significantly improve the production efficiency, but also to achieve the mechanism of grit type, grading, the amount of flour and other indicators of an overall upgrade, the performance of the mechanism of sand comparable to natural sand, sand stone, cement, concrete, dry mortar industry chain development to create new opportunities and values.
