Powder materials metering device includes: anti-sticking coating covered electronic scale measuring hopper No.4, electronic sensor, vibrator, pneumatic discharging valve No.26, material weight monitor, electronic control device, etc. Wherein the hopper has an effective volume of 400L, max capacity of 500Kg, and the measuring accuracy is level 4 scale tolerance.

c. Compressed air system includes: whole set of compressed air, air source treatment unit, soft and hard pipe, spray gun and nozzle equipped with release agent cylinder, etc. This system is used to purge mixing machine and cavities of forming machine, spray release agent and discharge materials and water for electronic scale and water system. Wherein the gas displacement is 0.3m³/min, the volume of air reservoir is 0.125 m³, and the motor power is 3KW.

d. Rack: It is used to fasten the above listed equipments, facilitate maintenance, etc.

2. Mixing machine of plaster block forming line

It is composed of mixing machine rack, stainless steel mixing tank No.14, openable stainless steel top cap No.20, spray pipe which is installed on the top cap, motor blender No.19, discharging oil tank No17, etc.

3. Forming machine of plaster block forming line

The forming machine is designed based on the formwork erection jacking theory. Besides the described mold characteristics, the forming machine also includes: hydraulic forming scraper which is installed over the cavities and on both sides of the mold, bottom die with sealing device, as well as rack, base, beam, column, the main oil cylinder, ejection head, signal generator and other components.

The mold material adopts alloy steel that is electroplated with thick enough hard chrome on its surface and is mirror-polished. Then with high manufacturing accuracy and a fine adjustment structure of block dimensions to make sure all the blocks produced are of high precision, excellent surface finish, and also long life-span of the mold.
Adopt hydraulic automatic forming scraper to automatically scrape out a tongue-and-groove at the top of the block. This can help to ensure product quality, reduce workers' labor intensity, and achieve automation.

Specification of gypsum block: 500mm×600mm×80mm

Cavity number: optional

4. Central hydraulic station of plaster block forming line

It includes: high and low pressure oil pump and drive motor, fuel tank (with oiler, liquid level indicator, hook, etc.), electromagnetic valve, one-way throttle valve, unloading valve, check or double check valve, discharging stop valve, oil filter, high and low pressure gauges, various valve seats, pipe fittings and so on. If necessary, manual pump, various valves, electric indicator light, electric control device of hydraulic caution light and other devices can also be included.

High pressure: 300 bar, low pressure: 150 bar

Overall dimensions: 850 mm × 530 mm × 1040 mm

The system contains an automatic high and low pressure switching device which can prevent the gypsum slurry from blocking in the cavities.

5. Pneumatic flexible fixture of plaster block forming line
Pneumatic flexible fixture-on-rails: install fixturing trolley with wheels on two rails. The trolley can move at high or low speed, advance and retreat, and has the functions of brake positioning. The main body of pneumatic flexible fixture cooperates with the elevating rails of the trolley frame. It can adjust the elevating speed through the control of signal generator. So this pneumatic flexible fixture-on-rails can conduct accurate three-dimensional positioning and guiding. It can form a full-automatic machine unit with above mentioned equipments through programmable logic controller (PLC).

6. Automatic control system of plaster block forming line

The system uses programmable logic controller (PLC), and is composed of a button box, an electric control cabinet and other devices near the operators. This system, according to the production technology and working cycle, has formed the screw feeder, dosing system, mixing machine, forming machine, central hydraulic pressure station, pneumatic flexible fixture and other equipments into an organic and efficient whole under the requirement of satisfying the interlocking and interacting of each equipment, ensuring the maximum product quality and production efficiency.

Brief Introduction of block by plaster block forming line

Gypsum block is a lightweight block-shaped building gypsum product made with building gypsum as the main raw material, add water and mix, casting molding and drying. In production, lightweight aggregates, fiber reinforced materials, foaming agents other auxiliary materials can also be added according to the performance requirements. Sometimes we can also use some high-strength gypsum (α half-water gypsum) to replace building gypsum.

Shape of block by automatic plaster block forming line

The shape of gypsum block is a flat cuboid with tenons and grooves on four sides in vertical and horizontal directions, respectively. In addition, gypsum block can be divided into two categories: solid and hollow block.
According to the Draft International Standard, the length of gypsum block should not be greater than 700 mm, the block height should satisfy a block surface area of not less than 0.25 sqm, and the thickness is 60 ~ 150 mm. Recommended block size: 666 mm in length, 500 mm in height, 60 mm, 70 mm, 80 mm and 100 mm in thickness, that is: three piece of blocks form a wall surface of 1sqm.

Appliance of block by plaster block forming line

Gypsum block is mainly used on non-load-bearing walls of frame structure and other structure buildings, generally used as internal partitions. If appropriate fixed and braced structures are used, the wall can also bear heavier load (such as: wall cupboards, water heaters, bathroom appliances, etc). Moisture-proof blocks which are laced with special admixture can be used in bathroom, toilet, and places which are not continuously damp.

Advantages of block by plaster block forming line

Gypsum block has the advantages of lightweight, precise size, fireproof, seismic resistance, thermal insulation, indoor humidity adjustment, excellent processability, convenient construction, etc. It is an environment-friendly and energy-saving green product that is emphatically promoted by the state.
