Sand and gravel separators have become necessary equipment for concrete mixing plants. At present, there are many kinds of them on the market, including integrated and split ones in form, roller/auger and vibrating screen in style, sedimentation tank, filter press and slurry recovery system, and the price ranges from hundreds of thousands to millions, making it difficult for enterprises to make a right choice. Sand separator is a necessary product of current environmental protection equipment, which is widely used in concrete mixing plants and can reduce the impact of concrete on the environment.
Scope of application: It is widely used in the product classification of mining, building materials, transportation, energy, chemical and other industries.
Applicable materials: river pebble, iron ore, coal gangue, granite, basalt, quartz sand, dolomite, limestone and other materials.
Equipment features:
- 1. Higher classification accuracy
The separator is equipped with a national patented “eddy current rectifier”. The air flow in the rectifier only rises relative to the rotor and does not rotate.
- 2. Easy to operate
The grader adopts stepless speed regulation by frequency converter, which is convenient, sensitive, reliable and wide in quality regulation.
working principle:
This product breaks through the sand and stone separation theory of conventional road and sky water washing, and divides the dry materials into three parts, namely, coarse particles, medium particles, and fine particles.
The main components of the sand separator vibrating screen are composed of six parts: feed tank, mixing separator, water supply system, screening system, slurry homogenization, recycling and waste slurry reuse system. When the residual concrete and water enter the material trough, the circulating water shall be continuously injected at the same time. Under the impact of the water flow, the mixture slurry enters the separator with the water inlet to fully clean the residual concrete. T
he cement slurry water continuously flows out of the slurry outlet at the bottom of the separator and into the slurry tank through the slurry guide tank. The washed sand and stone are driven by the spiral blades in the mixing separator, and after separation, they fall into the material pool through their respective outlets. The cement slurry water flowing into the slurry tank from the slurry tank is measured by the superposition method and the specified proportion of clean water, and the separated sand, stone and slurry water are reused.
Performance advantages
- There is a sand and stone separation system inside the sand and stone separator, which can quickly and effectively separate the sand and stone. The spiral direction of the screen tube is designed at an angle to the horizontal, so that the material can be filled and turned over in the limited screening process and be cleaned and separated by jet water. The sand stone separator can completely separate the sand stone at one time, and the separation time is about 30 minutes.
- During the use of the sand and gravel vibrating screen separator, the waste outlet will be cleaned regularly to prevent the sewage outlet from being blocked by mud agglomeration. The times of cleaning the sewage outlet will be increased. In order to improve the service life of the sand separator, it is necessary to take management measures for the sand separator in daily life to make the sand separator operate better.
