The controlling effects of the other traditional inhibitors on the average particle size of bentonite are not obvious. The order of average particle size in different suspensions is ATPE > KCl > KCOOH > JLX-B > distilled water > FMS-1, which proves that ATPE has a strong inhibition ability to clay dispersion.

Apr 25, 2018· Particle size distribution test. Figure 4 shows the particle size distribution of the bentonite dispersions when these are treated in different ways. Compared to the un-hydrated control sample, the average size of hydrated bentonite particles increased from 16.25 to 32.94 μm. This is different when DEM was added before the hydration of bentonite.
Particle size distribution of both barite materials are shown in the above chart. The chart plots particle diameter in microns vs. volume % of both the 4.1 and 4.2 SG barite. It is readily apparent that both materials are of near-equal particle size distribution.

May 29, 2019· Continued additions of prehydrated bentonite are necessary to maintain desired viscosity. Although very little filtration control is provided with prehydrated bentonite, the particle size distribution may aid in filtration control. Attapulgite can be used as an alternative viscosifier when freshwater is unavailable to prehydrate bentonite.
Apr 25, 2018· Figure 4 shows the particle size distribution of the bentonite dispersions when these are treated in different ways. Compared to the un-hydrated control sample, the average size of hydrated bentonite particles increased from 16.25 to 32.94 μm. This is different when DEM was added before the hydration of bentonite.
Particle Size Distribution Test Fig. 5 depicts the particle size distribution of the bentonite dispersions treated with different ways. Compared to control sample, the average size of hydrated bentonite particles was much smaller, and the addition of QAS-2 can only influence the particle size slightly, as shown in Table 3.
Crusher - Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Bentonite is easy to hydrate and disperse to smaller particles, which will increase the viscosity during the drilling process. The effect of ALS-2 on the bentonite particle size in water was investigated (Figure 3 and Table 3). It shows that the bentonite particle size distribution is quite different when treated by different ways.

The swelling rate of clay with FCLS-2 (w/w = 0.3%) decreased to 41.9%. Compared with control, FCLS-2 displayed high inhibitive ability against the hydrating and swelling processes of clay. Thus, the swelling degree of samples with FCLS-2 was much lower than that of the control, as well as the mud ball was more stable in FCLS-2 solution.
