Many of users are mistaken for the different types of LECA production is just the difference between material aspects and there are no differences in production. It is not true, different production materials also have different production processes. Now, DAJIA show you how the LECA production taking several typical raw materials as example.
1. Shale leca: There is a another name known as oil fracturing proppant, from the name of the above, we can basically conclude that the main raw materials for leca product is the commonly seen shale. The main production process: drying, grinding, pre-wet granulation, roasting and cooling.
2. Clay leca: Raw material is mainly clay, no need crushing, need firing, uniformity is very important during plasticized, and then through the ground into a powder, pre-wet granulation, firing and cooling.
3. Fly Ash leca and other different types, more or less there will be some differences in the production of the time, so use also have strengths.
