Parameter characteristics and application development of sand and gravel separator

The sand and gravel separator is mainly used for limestone removal in concrete mixing plants, and for the separation and recycling of remaining concrete, stone materials, and water. This device can solve the pollution of waste concrete and save resources. It is easy to operate, easy to maintain, consumes less power, has a high return on investment, fully automated process control, and displays alarms for all faults. Ideal environmentally friendly and energy-saving product for mixing plants.

The characteristic parameters of the sand and gravel separator, also known as the dry land sand separator or sand separator, are a type of sand separation vessel, frame, reducer, conveyor belt, and rotary screen suitable for rivers, reservoirs, and coal yards.

Production: Generally 50-150 tons/hour, depending on the size of the mesh, the larger the mesh, the higher the production.

Whole machine power: refers to the sum of the power of the raw material belt, finished product belt, and rotating motor.

Finished product stacking height: This height is related to the volume of finished product stacking, the height of transportation vehicles, the height of storage hoppers, etc.

Storage hopper capacity: The larger the capacity, the lower the feeding frequency of the loader, and forklifts can consider feeding into the mixing plant.

With the development of technology, the significant features of sand and gravel separators are compact structure, spacious working area, and the ability to accommodate two mixing station trucks for unloading and cleaning at the same time. Adopting a unique cross-sectional water washing device, the material is uniformly and cleanly fed into the sorting system, avoiding overloading of the sorting system at any time and reducing the labor intensity of workers.

1、 Stone based system:

The screen tube of the sand sorting machine adopts a horizontal slope design, which can fully flip and wash materials through jet airflow within a limited screening time.

2、 Sorting system:

Reasonable arrangement of overflow channel height in the sedimentation tank of the sand slurry separator to fully separate the sand slurry. The spiral conveyor and the inner wall of the casing are asymmetric. This is placed on the inner wall of the shell. The stacking layer can prevent material wear, extend the spiral, and completely dehydrate the material during transportation.

3、 Electrical control system

The electronic control method using Siemens technology has improved the stability and performance of the entire machine. All control boards are installed in switch boxes that are not affected by weather. Fully automated operation, simple operation, and easy maintenance.

4. Water supply:

The whole system cleaning process adopts circular cleaning, with almost no discharge of sewage and high utilization of water resources. In response to the characteristics of winter operations in the north, this product uses a heater.

5. Petroleum system:

Adopting a fully automatic lubricating oil pump imported from Germany, the oil can be fully transported every time, reducing manual operation.
