Product description, Product introduction:
The main chemical composition of gypsum is CaSO4, mohs hardness is from 3 to 3.5, the density is from 2.9 g/cm3 to 3.1 g/cm3. The fusion of gypsum in acid is greater than water, and is made by crushed gypsum ore.
The gypsum used for friction materials in order to improve the coefficient of friction, reduce the cost. Gypsum is used for the disc brake pads and drum brake and clutch. The recommended regular consumption of Basalt is from 2% to 8%.
The character of gypsum:
Gypsum is most widely distributed mineral in the nature, in a broad sense is containing calcium sulphate (CaSO4) of white mineral. Natural gypsum is divided into two major categories of gypsum and anhydrite according to chemical composition, and can be divided into five kinds of fiber gypsum, gypsum, alabaster, ordinary plaster, earthy plaster according to the shape and structure.In the gypsum mineral deposit in Lingxiang Town Daye city, transparent single crystal gypsum crystal group is found growing in the iron ore deposit cave.Gypsum has the character of good lubrication, solidification, heat acid and alkali resistance, heat insulation and good for oil adsorption, etc..Because of the glittering and translucent white, like baby's blanket long, has the elusive mystery, the single crystal of gypsum prisms surface to the 5cm to 6 cm wide, the elderly can be up to 16 cm, still keep 10cm to 20 cm long inside some crystal gas-liquid inclusions swam back and forth, wonderful and moving!

We independent research and development a new set of no paper faced gypsum board production line in 2015.It takes us 6 years .This equipment will be less investment and quick returns. It is easy to handle with less labor and highly output.
Our r&d philosophy is more green, more saving and more environmental protection.
Besides all the advantages of traditional paper faced gypsum board, the new no paper faced gypsum board has many itâ??s own characteristics.
Fireproofing grade: the traditional gypsum board fireproofing grade is b, but the new no paper faced gypsum board fireproofing grade is a. Perfect fireproofing material.
Environmental protection: it will save a lot of paper and more effective to protection the tress, the forest.
Production cost: because there is no need to use protection paper, modified starch, white latex, the production cost will be cut off a lot.
Production pass rate: it will be higher than traditional paper faced gypsum board. Because the donâ??t stick paper will be disappeared.
Applied rangeï¼?it will be wider than traditional paper faced gypsum board, special in the often raining places. Because there is no paper, starch and latex, mildew and coating shedding will be not occurred.
Market prospect: because of the characteristics above, it will be the upgrade and update of the traditional paper faced gypsum board. The market prospect is perfect.
In addition, this new machine also can produce cement cladding board, waterproof gypsum board by changing the recipe. After little machine adjusting, it also can produce the perlite composite board.
1(1.5, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20) million square meters per year gypsum board production line
Paper faced gypsum board is a kind of lightweight construction board(made with calcined natural gypsum or outgrowth of chemistry)use the construction gypsum and face paper as the primary raw material, mixed with relevant fiber, modified starch, speed freezemeter, vesicant and water; produced through mixed, molded, froze, incised and dried such working procedure.
Paper faced board is lightweight, fireproofing, soundproof, dampproof, heat insulation, and have a good capability that can be nailed, cut planed, its good for tooling, knocked-down, easy for completion, and can enlarge the space.
Its widely be used in industry construction, civil construction, especially used as crossbanding for interior of high buildings, such as: used for unload wall board and ceiling board.
The gypsum board production line was based on the inland and overseas equipments that have been improved and innovated.
It reached an absolute automatic level in self-mixing, self-molding, self-supplying, self-outputting, self-turning, self-cutting. We can provide different grades (high, medium, low) production line according to the require of customers.

The grade of mine and the crystal configuration will influence the quality of semi-hydrated gypsum
3, working principle
The main working principle for calcining system, of calciner
The main body of calciner consists of fine diameter intensive radiator pipes. Thermal oil fed into the coil pipes. The heat releases into power by heat exchanger. Roots blow installed at bottom of calciner for putting the cooling air into furnace by grid plate. The cooling air blows gypsum power in furnace for reaching boiling state. At certain temperature , the calcined gypsum power will lighten, and flow automatically to outlet. This type gypsum power is state in quality. It is easier to control the content of free water , initial and final setting times.
Moreover, our equipments adopt dry electric precipitator, dust collection efficiency is over 95%.
4, simple structure, durable equipment
The boiler does not need rotary components because the materials has come true fluidization. It simplifies the structure, manufacture and maintenance. In any case, the furnace will not damage since it uses low-temperature heat source. The life span is much longer than normal type.
5, compact, space saving
Calciner is a kind of vertical equipment. The dust collector installed on the top of it as whole body. This design is good at space saving, and avoids moisture condensation on corona lines of dust collector.

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO·2HO). It is widely recognized for its versatility and is commonly found in sedimentary rock formations. The primary use of gypsum is in the construction industry, where it is a key ingredient in the production of plaster, drywall (also known as gypsum board or sheetrock), and cement. Gypsum's ability to harden when mixed with water makes it ideal for creating smooth wall finishes, ceiling tiles, and as a fire-resistant barrier in building materials. Additionally, it is used in agriculture as a soil conditioner to improve soil structure and nutrient availability.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4.2H2O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard.
