1.ATAIRAC Wet Type Sand Making Plant Introduction

 

1. Wet Type Sand Making Plant Features
    
       (1) Good-shape granularity
       (2) Consecutive grade of granularity
       (3) Reduced dust emission , low noise
       (4)The whole system has water spray / sand washing machine / fine sand recovery device / sewage treatment system
    
    
2. Difference between dry sandmaking and wet sandmaking
    
    
   At present, the commonly used artificial sand making methods can be divided into two types: dry sand making and wet sand making. The dry sand making process starts later than the wet process. The dry sand making process is further promoted on the basis of the wet sand making process. The wet production process is suitable for areas with abundant rainwater resources in the south. In the south, the temperature is high, the rainfall is high, the amount of red soil contained in the sand and gravel raw material is high, and the weathering degree is relatively high. Compared with the sand and gravel in the northern region, the same material has less hardness, and it is easy to be processed into fine powder, which is wrapped on the surface of sand and aggregate. , Affecting the quality of sand and aggregate.
    
   Dry sand making process:
    

1. can use large size crushed stones below 40mm as raw materials;
2. crushed by large ultra-fine sand making machine, easy to control the generation of stone powder; 
3. using air separation equipment, no need for spiral stone washing machine and other equipment;
4. The initial investment cost is small;
5. Easy to operate and manage, and the operating cost is cheap;
6. It can process high-quality artificial sand that is similar to wet production. The raw material contains mud which is not easy to handle, which affects the quality of the finished sand; The sand making raw material requires drying.
    
   Wet sand making process: 

1. Generally use crushed stones below 25mm as raw materials;
2.  Because all are crushed with a stone washing machine, excessive stone powder is generated, and water is easy to lose;
3. A large amount of sewage is generated, and large sewage treatment equipment is required;
4. Medicine is required And other additives;
5. High initial investment costs;
6. high operating costs;
7. can produce artificial sand of good quality.

1. Advantages of wet sand making process
    
   1) The surface of the produced aggregate and sand is clean, with good perception and good quality;
    
   2) Use a large amount of water to wash, the production environment is not polluted by dust.
    
2. Disadvantages of wet sand making process
    
   1) During the production process, a large amount of water resources are consumed. Generally, 1 ton of sand and gravel production requires 2 to 3.5 m³;
    
   2) The artificial sand produced has a high water content, less particles with a particle size of less than 0.16mm, a coarser fineness modulus, and a lower sand output;
    
   3) A large amount of mud powder sewage is discharged during the production process, which pollutes the environment, has high recycling costs and poor results;
    
   4) There are many types of equipment, too much floor space, high operating costs, difficult operation and management, and high production cost of artificial sand;
    
   5) Sufficient water resources are required, and normal production cannot be performed in arid and rainy areas or in cold and icy seasons.
    
3. Normal Wet sand making equipment configuration:

1. Vibration feeder: It can evenly and quantitatively send the materials in the silo to the crusher, which can effectively avoid the blocking of the inlet, simple structure and convenient operation.
    

1. Jaw Crusher: Roughly crush the raw materials in the silo to meet the crushing requirements of the cone crusher, with high crushing efficiency, large output and low failure rate.
    
2. Cone Crusher: Medium and fine crushing of materials. After crushing, the sand meets the requirements of sand making and enters the sand making machine for sand production. The principle of lamination and crushing, high yield, energy saving and environmental protection.
    
3. Sand making machine: an important equipment for producing artificial sand, which can crush the material to about 30 mesh, excellent finished products, good grain shape, strong processing capacity, equipment can be used for multiple purposes, and the cost is low.
    
4. Vibrating screen: There are two layers, three layers, and four layers in the sieve layer, which can separate the different grades of materials after crushing. The screening efficiency is high, the operation is reliable, the operation and maintenance are convenient and fast.
    
5. Sand washing machine: Also known as stone washing machine, it can effectively remove impurities covering the surface of sand and gravel, with high cleanliness, few wearing parts and long service life.
