The crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments. As a result of the specific geometry between roll body and crushing segment an optimum formfit is achieved, thus being able to stand up to the high crushing forces.

Crushed gypsum with a particle size up to 15 ... Additional energy consumption is required for purifiion. ... The setting time of a Portland cement is increased as the quantity of gypsum added is increased, up to a certain level where a plateau is obtained and the setting time becomes insensitive to further additions of gypsum. 32.

Crushing the gypsum rock is advisable before processing further, especially if subsequent heating is to be done in a pan rather than a shaft kiln. Crushing will ensure a product which is more uniform and requires less energy to heat. Crushing can be done manually with a hammer or handheld roller, but mechanical crushing is faster and less ...

The crusher specific electrical energy represents the energy consumed by the different elements of the crusher to produce a ton of cement. The major equipment that consume electrical energy at the cement crusher are: main engine with a power of about 4000 Kw, ventilator with a power of the order of 2000 kw and separator with a power of the ...

systems and low specific energy consumption Pyroprocessing Pyroprocessing includes preheating, precalcining, burning and cooling as the major components and is the most important thermal energy consumption centre in the cement plant. Conversion from wet process to dry process technology for

Gypsum is first crushed and then dehydrated to produce a powder. This powder is further crushed to obtain a specific surface area and then screened to remove any particles that are too large. Minor additives are weighed, added and then blended with the gypsum powder to produce a finished product. The finished product is packed into bags for sale.

 · The primary impact of the maximized incorporation of recycled gypsum observed in Fig. 2 is a % increase of electricity consumption, which, given the low share of electrical energy in the total energy demand of the process (see Fig. 1), results in negligible overall net effect ( % increase) and total energy consumption remains practically invariable in both .

 · The energy for crushing, E, is the difference between the energy of the input pendulum and the energy of the rebound pendulum and is computed from the following expression: () ɛ E = E S 1 − ɛ 2 M B M B + M S Units: energy terms ( E ) = kWh/t = 3600 kJ/t. mass = kg. the value of ɛ = 0–
