Can waste glass be powdered? What equipment is needed?

Glass products are essential in our life. While they bring us beauty and practicality, they will inevitably be broken and become waste glass. In the face of a large number of waste glass nowhere to be placed, this paper Fodamon engineer introduces the path of how to turn waste glass into treasure. With the development of various crushing and grinding equipment, only one glass crushing and grinding production line can solve the problem of waste glass pollution and waste. More importantly, it has brought considerable profits to processors.

Ⅰ. Application and Prospect of used glass grinding powder

After the waste glass is ground into glass powder, it has the characteristics of small particle size, good dispersion, high transparency and good anti sedimentation effect, and has great achievements in the industrial field:

  1. Used for producing high-grade furniture finish. The mixed use of glass powder and coating can improve the transparency of the coating, especially in furniture paint. It has yellowing resistance, high temperature resistance, UV resistance and natural powdering resistance, and can also increase the wear resistance and folding resistance of the coating.
  2. For construction. Adding glass powder to concrete can improve the basic chemical properties of cement and make it more durable, and it does not absorb water as fast as ordinary cement.
  3. Used for processing pipes, oxygen cylinders, FRP helmets, handicrafts, etc. In addition, in the railway, construction, aerospace, decoration, advertising and other industries, the economic utilization value is considerable.

Ⅱ. Equipment required for grinding used glass

From waste glass to finished glass powder, it is mainly divided into two steps: crushing + grinding. The equipment used include vibrating feeder, crusher, pulverizer, vibrating screen, sand washer, etc.

The equipment that can be used in the crushing stage are:

  1. Jaw crusher
    It is mainly responsible for the coarse crushing of waste glass. The maximum feed particle size can reach 1500mm. If your raw material particle size is large, you should choose it. The jaw crusher has simple structure and reasonable design. It has a deep crushing chamber without dead angle. The output is 1-2200t / h and the finished product is 10-400mm.
  2. Impact crusher
    The hardness of glass is not high and it is easy to break. Therefore, it is more appropriate to choose the counterattack breaking with relatively low price. It not only has high output and low price, but also has good particle shape of finished products. It is a good choice for materials with medium hardness!
  3. Hammer crusher
    It is a typical one-time forming equipment, which is equivalent to the effect of a jaw breaking + counterattack breaking. Moreover, its output is up to 3200t / h, the price is cheap, and the feed particle size can reach 1700mm. It is a high cost-effective choice.

The equipment that can be used in the milling stage are:

  1. Raymond Mill
    It is a commonly used grinding equipment. The particle size of its finished products is arbitrarily adjusted between 80-325 mesh, which can meet the general needs of glass milling.
  2. HGM mill
    If your finished product granularity is required to be finer, you can choose it. The finished product granularity of the equipment is finer, which can be adjusted arbitrarily between 80-800 mesh, with higher technical content, more advanced performance and higher price than Raymond mill.
