The pharmaceutical industry is in the midst of a transition from traditional batch processes to continuous manufacturing. However, the challenges in making this transition vary depending on the selected manufacturing process. Compared with other oral solid dosage processes, wet granulation has been challenging to move towards …
The process of non-pressure agglomeration can also be used for the granulation of mineral resources used in the production of agricultural fertilisers and as an additive to plant biomass waste.
Gypsum shipments from the Sultanate of Oman, currently the world's biggest exporter of the industrial mineral, are projected to grow exponentially over the next decade as consumption rebounds in key markets, while traditional exporters curtail …
1. Introduction. The term "Granulated" is derived from the "Granulatum", a Latin word denoting a grained mixture. In the pharmaceutical industry in the granulation process, the term "granules" denotes finely powdered particles that aggregate to create a larger, intricate structure. 1 These formations usually range from 0.2 to 0.4 mm. . …
• Micronized gypsum granulation is in the micron range (below 200 microns = 0.200 mm) which is used for polishing (smoothing and polishing the final gypsum surfaces) as well as for gypsum cutting and tooling in …
This article shows research confirming the thesis on the use of a new material in the form of gypsum, paraffin, and polymer. The article presents an innovative method of preparing plaster with PCM and polymer. Using a special wheel, it was possible to produce a granulate consisting of a mixture of gypsum and paraffin and then spray it with various …
Our disc granulator production line mainly produces compound fertilizer with an annual output of 50,000 tons. In general, compound fertilizer contains at least 2 elements of three nutrients (nitrogen, phosphorus, and potassium). With features of high nutrient content, few side effects, and good p...
However, clumping and dusting issues may occur when drying and pelletizing powdered gypsum. In order to avoid such issues, equipment such as pin mixers, disc pelletizers, and rotary dryers are used to process gypsum into pellets. A pin mixer pre-conditions the gypsum material using a binder solution and the rotational mixing motion of the pins.

In order to expand the product range of Nordkalk Poland sp. z o. o. located in Poland, the granulation conditions of the gypsum–lime mix were examined with the use of various granulation methods.
Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO2) gas, is the primary contribution coal makes to FGD gypsum. Utilities that produce panel-grade synthetic …
After 3 min, mineral additives, dolomite, and dry and wet gypsum were added to the rotating bed. No binding liquid was added in the granulation process. Granulation was run until the majority of the fine-grained material was attached to the granules, making sure that the agglomeration of granules did not occur (no coalescence …
However, there may be relatively more amount of loose dihydrate gypsum crystals formed during the granulation process, and the final PG hardened tiles with decreased bending strength is obtained (Fig. 3). Thus, the optimal water incorporation is 35%, and the corresponding PG hardened tiles have an excellent 7-day bending …
The granulation process is a unit operation with broad application in the fertilizer industry. The granular fertilizer has a better physical appearance, facility of agricultural application and elimination of fugitive dust in the production and bagging units. Phosphogypsum is a residue from the production of phosphate fertilizers. It known that …
Experimentally-determined and calculated gypsum precipitation potentials from Dead Sea brine-seawater mixtures at T = 25 °C and P = 1 atm. The experimental data are derived from Reznik et al., [58].
The paper assesses the influence of the calcination temperature of synthetic gypsum binder on the binding properties of innovative gypsum pastes, as well as on masonry and plastering mortars. The calcination process of gypsum binder was carried out at four different temperatures ranging from 170 to 190 °C. The specimens for testing …
The phosphoric acid and ammonia are pre-neutralized (reacted) in tanks to form a slurry. This slurry is then fed into a rotary granulator, where it forms granules as it tumbles through the drum and solidifies.. These granules are then carried via conveyor or bucket elevator to a rotary dryer where they are dried into their final form. The tumbling action of the dryer …
The main points of innovation are primarily the use of wet granulation to produce gypsum granules. The granulation process itself is known, but there are no studies leading to its use in gypsum mortar. In addition, the study prepared a ready-made product consisting of granules and poured with gypsum, thus imitating a plasterboard. …

In addition to the cation exchange, the formation of cementitious hydration products such as (CSH) and (CAH) has also been reported in gypsum-treated clays (Latifi et al., 2018; Zha et al., 2021).The CSH and CAH can be produced through the pozzolanic reaction if the calcium from gypsum reacts with soluble alumina and silica from clay in …
Of course, gypsum is not naturally available in a usable, pelletized form for soil amendments. Gypsum rock must be excavated from mines or quarries, then crushed and ground into a fine powder. Once gypsum is in a powdered form, it is ready to begin the pelletization process. Click the image below to view our infographic on gypsum soil …
