The finished product features with good shape consecutive grade of granularity and adjustable fineness modulus. By using centralized dedusting method the Plant efficiently controls the dust emission.


2. Features
ATL dry-type sand making equipment developed by ATAIRAC makes breakthroughs in the vertical-shaft crushing, air screening and other key technologies and uses the five-hole impact rotor structure, the state-of-art technology to crush, shape and grind raw materials entering crushers through rotors using the "rock breaking" centrifugal crushing method. This achieves self-generated crushing and high-strength self-generated crushing, thereby efficiently improving the particle shapes of finished sand and increasing the output of fine aggregate.

The ATL sand making equipment uses the air screening technology to achieve perfect classification on transfinite particle size, finished sand and sand powder, thereby maximizing the screening efficiency, and uses intelligent control to make the fineness modulus of finished sand adjustable. In addition, the equipment uses the dust collector technology with offline ash removal pulse to efficiently control the content of rock powder in finished sand and operate the whole system in a closed negative pressure environment, thereby realizing the value ideas of green and intelligent sand making for environmental protection.

3. Characteristics

01VSI Vertical-shaft Impact Crusher
(1)Deep cavity design enables bigger inner space of impeller, therefore more throughput capacity and higher efficiency;
(2)Reasonable inner structure, the material liner forms on the chamber wall, which could effectively extend the service life of impeller and wearing parts, reduce usage cost.
(3)High, middle and low speed grades are optional, which amplify the crusher efficiency, and combine crushing, sand making, re-shaping functions as one,
(4)The wear-resistant plate and surfacing on the impeller upper plate provide dual protection, which ensure the impeller safety and repeating use.
(5)Higher manufacturing accuracy and dynamic, static balancing technology make the impeller outstanding in unbalance resistance.
(6)Modularized wearing parts design ensures high generality, less wearing parts type and convenient wearing parts replacement.
02 Air Screen
Vibration transmission and dispersion technologies
The vibration screen combine separation and selection technologies
The intelligent air regulation for air blowers can control wind force during screening and clean the surfaces for sand
The new polyurethane mesh can prevent blockage and improve the screening efficiency.
The fineness modulus is adjustable with the stability reaching ±0.1.

03 Sand Powder Separation Technology
The air separation technology with inertial classification requires no energy consumption.
The adjustable guide plate design maximizes the air flow path.
Corse particles (with a size bigger than 40μm) in the reclaimed sand powder improve the quality of finished sand, thereby ensuring a reasonable graduation of finished sand.
The technology can reduce power consumption during dust collection and improve dust collection efficiency.

04 Dust Collector
The high-efficiency bag dust collector provides the offline ash removal dust collection function to achieve a dust collection efficiency of 99%.
Polyester peritoneal filter bags provide excellent filtering performance, with the carbon concentration less than or equal to 20 mg/m³ (under rated conditions).
Automatic differential pressure signal feedback brings high-performance automatic pulse control.



05 Electronic Control System
The unique algorithm and control mode are used.
The graduation and fineness modulus of finished sand are adjustable, and the sand powder content is controllable.
Intelligent management for quick-wear parts is used.

2. Introduction of Wet Type Sand Making Plant

 Wet type artificial sand/aggregates plant adopts full steel structure with little dust and noise, which has the a dvantage of smart working flow, quick installation and high production efficiency. The finished product featurres with good shape, consecutive grade of granuIarity and adjustabIe fineness moduIus.

This production line utilizes fine sand recovery device and is designed in the form of horizontal style. The comprehensive  methods  are  applied  to  reduce  noise  and  vibration,  and lower the dust emission.

3.The basic difference between fine sand and ordinary sand
  
    1) The requirements for fine sand feeding are more strict, such as soil content, water content and ordinary sand are not so strict

2) The requirements for the finished products of fine sand are more strict, and the powder concentrator and fineness modulus must be added, while the ordinary sand does not have to add the powder concentrator or and fineness modulus need not be adjusted.
