What is dry mortar :
Dry mortar is also called pre-mixed mortar, which made in the factory by precise batching and uniform mixing. It can be used directly just by adding water in construction site. It has different properties though adding different additives. The demand for dry mortar has increased rapidly due to its outstanding merit compare to the mortar production in job-site.
Raw material of dry mortar :
1. Cementing material: cement, lime, plaster.
2. Aggregate: yellow sand, quartz sand, limestone, dolomite, expanded perlite etc.
3. Mineral admixture: industrial byproduct, industrial slag, fly ash, pozzolana, fine silica powder etc.
4. Water-retention and thickening material.
5. Chemical additives.

Working Principle and Process :
Working Principle :
Materials are fed into surge bin from customer`s hopper. This process is controlled by a rotary gate and a pneumatic valve on top of the surge bin. The feeding proess is controlled by a frequency convertor operated impeller and a valve at the spout.
When reaching target value, the impeller stops and the feeding valve closes, sack-clamping device is open and the filled bag could be moved out manually or automatically. The machine is ready for a new filling circle.
According to requirements of the customers, the system can be equipped with 3-6 bulk storage bins, the material in which will, after being processed by the metering and batching system, be conveyed to pending-for-mixing bin, and then fed into the high-efficiency biaxial agravic mixer for continuous mixing. The finished product in conformity with mixing accuracy requirements can be sent to the finished products bin shortly after mixed. Moreover, there is design with automatic rationing and packaging machine at the bottom of finished products bin, allowing for synchronous auto-packaging operation. Featured with easy and convenient operation, high efficiency, it can both obviously reduce labor intensity and effectively reduce dust pollution.
