Gypsum is calcium sulfate dihydrate, a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate, commonly called stucco. Zenith's gypsum screening and crushing plant 80kva is specially designed for the production line.
To get the most from your crushing circuit, it should be designed based on the deposit's mineralogy. Conduct tests for density, abrasion, psi levels, and silica content to determine the best crusher configurations for your site. Also keep in mind the desired product mix. For example, if fines are desired, impact crushing makes sense. Conversely, compression crushing can help operators avoid fines production.
The crushing process starts with the vibrating feeder. Through it, the block materials will be taken into jaw crusher evenly and gradually for the first crushing process. Belt conveyor will send the materials to cone crusher or impact crusher for the secondary crushing process. In this stage, the materials will be broken into fine or ultrafine size. Vibrating screen is used to separate the un-qualified size materials which will be taken back to crusher by belt conveyor to be crushed again. Till all the materials are crushed into qualified size which meet the next production needs, the crushing process is over.
Meanwhile, pre- screening material ensures more consistent and even material flow to the primary crusher. Undersize material is pulled out and sent to the discharge belt, while oversize material is sent to the crusher. By reducing the material going into the crusher, operators can reduce wear costs while increasing production levels. And, some of the mud and contaminants are removed from the material during screening.
