River sand drying equipment-dry mortar production factory
River sand drying machine use advanced technology and economical vibrating fluidize dryer. Compared with traditional drum dryers, fluidized sand dryers have the following advantages: high efficiency and economy; almost no radiant heat loss; no relative mechanical movement, almost no wear; low maintenance costs; short startup time; low noise, etc. .
Dry sand grading and screening machine-dry mortar production factory
The projection type vibrating screening machine with reliable quality, it is low investment, compare with the traditional horizontal screening machine it is low investment; small size; reliable, even in the case of overload, the screen will not be torn due to the inclined setting; stable system error guarantees formula correction, thus guaranteeing product quality;
Materials Storage and loading equipment-dry mortar production factory
Cement and lime powder are generally sent into the raw material silo by pneumatic conveying equipment. Chemical additives can be manually poured into the small raw material hopper, the control system will automatically prepare ingredients according to the formula requirements, or they can be manually weighed and directly put into the mixer for use. The arrangement of the silo adopts a modular type, which expands from the center to the outside, making the investment in installments possible. The material usage status of the silo is monitored by the silo level gauge, and the feeding is controlled at the same time. The cone of the silo is equipped with a fluidization device, and compressed air is used to help discharge the material at the junction bridge.
Precision batching weighing system-dry mortar production factory
There are many ways to measure. Good performace transporting equipment are mainly improved screw conveyors. It is suitable for almost all powdery materials. The metering and conveying system should have high metering consistency (small output density or weight change with time) and wide adjustable range (1:30). These two points are high-precision base conditions, the screw spiral metering output is in a linear relationship with the speed . The control system is very stable. Sliding valve metering is only suitable for materials with good fluidity, such as granular aggregates larger than 1 mm. Due to the limitation of the opening degree, the adjustable range of its flow is very small, less than 1:5, and its flow rate and the opening agngle of the control valve (Valve displacement or rotation angle) is a non-linear relationship, which once again reduces the metering accuracy.
Screw conveyors have the following main advantages: large adjustable range; high accuracy; wear resistance (improved design and materials); simple maintenance and low cost; low operating costs (no need for compressed air for fluidization).
Efficient mixing system-dry mortar production factory
High-efficiency mixer is a key part in the production of dry mortar. After research, development and application,the mixing technology has been widely considered to be effective in uniform mixing of dry powder materials. The key design criterion is the effective mixing of materials in what state of motion. Therefore, the development of a series of high-efficiency mixers should be based on similar mechanics, and parameters should be determined by experience.
An efficient mixer should be able to achieve the following performance:
high mixing uniformity, the uniformity should be determined by relative variance and should be within the error range required by the quality standard, such as less than 1%;
high mixing efficiency, should try best to reduce mixing time for coarser particles so as to avoid the quality error caused by too large particle gradiation.
The unloading speed should be fast and finish within 10-40 seconds;
No residual when unloading, generally there is no need to clean the mixer when changing products;
Low energy consumption; use high-speed blades for fibers and pigments mixing;
the overall wear resistance design;
convenient maintenance to reduce operating costs.
Dry mixed mortar packaging machine-dry mortar production factory
For the packaging of coarse and fine dry powder materials, you should pay attention when choosing the packaging machine. Fine powder materials can be packaged with normal impeller type packaging machines. The airflow type packaging machine is more reliable for big sizes products.
