Gypsum Powder Machine

gypsum powder machine The big sized gypsum stones are crushed into granules which are less than 25mm by the crusher. After storing and conveying, they will be conveyed into mill for grinding.Then they will be classified through a analytical engine. The qualified powder will be conveyed to the calciner for calcination, while the unqualified one will return to the mill for further grinding until it is qualified. The calcined gypsum powder (it¡¯s usually called Plaster of Paris) will be stored in the finished product silo for the preparation of plasterboard raw material or directly packing and transport to the customer;s site. There are two types of the gypsum powder productionline. One uses the direct burning calciner (it is usually used in the small capacity line, such as 20000 or 30000 tons per year), the other uses the fluidized bed furnace (it fits for all the capacity of the gypsum powder line. This style is very popular in the gypsum powder industry.). Use 40 feet container to transport.

1. Gypsum powder quality standard: in compliance with GB/T 9776-2008 2. Main Technology(here take Nature gypsum rock as example) Gypsum rock - first crushing -second crushing - grinding - calcining - aging -finished products (CaSO4.1/2H2O) After being heated and calcined with certain temperature,natural dihydrate gypsum is dehydrated and decompounded,to get the product whose major component is semi-hydrated gypsum(CaSO4.1/2H2O),that is,calained gypsum(generally slaked gypsum).According to different temperatures and pressure conditions during dehydration decomposition,the obtained product is β-Type calcined gypsum.Basic process of mechanized prouduction includes five large systems:gypsum grinding,automatic measuring system,calcination system,heat supply system,and aging&packing system.According to client's requirement,gypsum crushing system can be added to crush large gypsum rock to be with size of 0-30mm,and then conveyed into grinding system. 3.Payment conditions: A. Payment terms: 30% T/T in advance; 70%L/C or T/T B. We can provide quality guarantee; C. Kunlun bank account available to make convenient for Iranian client National Standard of Calcined Gypsum Standard No.: GB/T 9776-2008 Scope of application: Gelled material made by dehydrating natural gypsum(raw material). Its main component isβ-GaSO4·1/2H2O, without any admixture or additive. The natural gypsum should be in conformity with requirements of "gypsum rock(JC/T700) for making cementing material" gypsum rock of Grade 3 or more higher grades. Classification: It is classified to be three grades: 3.0,2.0,and 1.6 according to its 2h strength(breaking strength). Composition: β-GaSO4·1/2H2O content(mass fraction) in Calcined gypsum should be not less than 60.0%.

Gypsum powder equipment is composed of elevating system, dust collecting system, conveyor system, heat supply system, milling system etc.. And the heat supply system is the key link of the whole gypsum powder production line. The gypsum produced by our company has the following characteristics: 1.The equipment has small volume but large yield. 2.The equipment with easy structure can not be damaged easily. 3.The compact equipment covers less area. 4.It has comparative less energy consumption. 5.It can be conveniently operated and easily controlled. 6.The products are of good quality and gypsum of Paris is of ideal components and stable physical properties. 7.The capital construction investment is small and operating expense is low.

Chemistry gypsum powder production line:ªG building gypsum powder. Chemistry gypsum is refers to the industrial production process, forms industrial products, such as desulphurization gypsum, phosphorus gypsum, fluorine gypsum, lemon gypsum and so on.Raw material characteristic:the surface water is more than 20%, the ingredient relative is unstable. Building gypsum powder production technology introduction: Uses raw material pre-drying , bolling stove calcine that two step calcine technique of production, use car loader to transport raw material from dump site to material basket, by beater, the belt conveyer to transport uniformly to the dryer(the heat source of this place is that burn coal the hot-blast stove), though collection powder equipment vertical transmisslon equipment brought into boilling stove calcined(that furnace heat is the htf stove), after calcination shipped goals mushroom grinding machine modified and cooling, and from promotion transportation to the warehouse, packaging warehouse.

When heating and calcining the dihydrate gypsum, the dihydrate gypsum will be decomposed, we can produce the semi-hydrated gypsum (CaSO4?/2H2O) , that is building gypsum, also called plaster of paris. Because of the different temperature and pressure when decompose the gypsum, we can get different product, a-type gypsum and b-type gypsum. a-type gypsum is high-strength gypsum,b-type gypsum is building gypsum. They are the same technology using mechanisation producing building gypsum. The process can be divided into three system, crashing system, calcining system and milling system. Wooden case & plaste

The main composition of gypsum is dehydrate gypsum©vCaSO4.2H2O©w. However, the gypsum powder used in practical production (such as the gypsum powder for gypsum board, for mould, for plastering) is to dry and dewater the dehydrate gypsum, reduce the content of crystallization water in it, so the standard of crystallization of gypsum powder can meet the needs of all kinds of gypsum powder, because it can change into plaster of pairs. Plaster of pairs can re-integrate with water when it is applied into production, and it can be processed into new type building materials with a high intensity, such as gypsum board, gypsum block, etc. 3. Existing gypsum powder drying technologies the following: the heat, produced by the burning of medium in the stove, is transmitted to frying cauldron and pipe of circumgyrate stove, then gypsum powders are added, after mixture and drying through milling equipments, the finished product is transmitted to the store house. In this way, the quality of gypsum powder is cheesy, because the content of crystallization water is uneven.
