High Intensity Petroleum Sustainer

Originating in China , Cermasite Sand is a revolutionary new artificial foundry sand, now highly regarded as an excellent substitute for chromite sand and zircon sand in the foundry and petroleum industries. Made from bauxite, it is heat resistant, cheaper to produce and use, environmentally friendly, while offering improved performance based upon a better refractory rating, lower specific gravity, and higher levels of AL 2 O 3 in its composition. It is used as single sand, eliminating the need to mix other sands, and can be reclaimed many more times than previously used sand. This raw material is processed into a tiny solid ball shape with a ultra-smooth surface. The characteristic properties of ceramsite provide better air permeability and overall dispersion in its application, producing greater industrial yields. For example, when used in an oil well deeper than 2,000 meters, the oil production rate will increase up to 3 times.

Characteristics of Ceramcite Sand

  1. Tiny, round, solid ball shape provides greater surface area for improved performance and dispersion in its application

  2. High refractory rating, lower specific gravity rating, and higher service temperature produces greater yield

  3. With lower bulk density, it offers better air permeability for better performance as a result of its overall physical characteristics

  4. Lower thermal expansion rate and thermal conductivity produces better results in intense heat environments

  5. Standard particle size within each grade is ideal for specific applications

  6. Raw material is easily reclaimed multiple times by dry method

  7. Physical characteristics produce a lower breakage rate during dry crushing

  8. Ceramsite sand is a cost effective, single sand application; no need to mix with other sands

  9. Ceramsite Sand is environmentally friendly, reducing pollution and reusing raw materials

Ceramite production process

Product ceramsite generally using the production process of raw material homogenization, granulation, baking, cooling. According to the type and characteristics of raw materials, Its granulating process can be divided into the following kinds:

1. Plastic method technology: Suitable for clay and clayey material.
Its process: clay - plasticizing, smoothing of roller and granulating - roasting - cooling - finished products. 

2. Mud into the ball process: Suitable for fly ash or other powder raw materials.
Its process: fly ash - mixed smoothing - into balls set granulating - roasting - cooling - finished products.

3. Powder grinding ball process: Suitable for shale, clay shale and gangue materials.  
 Its process: shale, drying, grinding, prewetting - into a ball dish granulating - roasting - cooling - finished product, the additive agent.

4. Broken (dry) process: Suitable for shale,etc.
Its process: raw materials and broken graded - roasting shale and finished product. And cooling.

5. Fuel: according to local fuel supply, using bituminous coal, crude oil or natural gas.

Ceramsite Sand Making Machinery

Ceramsite sand making machinery  includs crusher, screening machine,belt conveyor, feeding machine, discharge machine, raw material storage warehouse,dustfall room,induced draft fan,main kiln body,coal injection system and control cabinet,etc.The speed of the feeder under the raw material stroge warehouse, kiln body and the quantity of coal arching are all of stepless speed regulating.

ceramsite production process

Raw materials of ceramic production are mainly shale, clay, fly ash, industrial waste, river silt. Different raw materials and products of its production process performance indicators are also different.

In general, clay shale (siltstone and claystone of the mixture) of the extruded larger magnification, small bulk density, good insulation properties, but relatively low compressive strength of cylinder can be used to produce non-load bearing hollow block products. However, some areas are dominated by

siltstone and shale raw materials to produce ceramic body weight, for the production of load-bearing block, beam, plate and so on.

Shale ceramsite production

Shale ceramsite production process is as follows: Mining - once broken - Secondary Crushing - Screening - temporary - Feeding - sintering - cooling - finished grade filter - stack - Transport (equipment bags). In operation, should be noted that the volume of feed, the amount of coal, kiln speed, the wind volume matching relationship between them so that they adjust to the best of the process state. With fly ash and other industrial waste produced ceramic is many years of research topics relevant parties.

Today, high-strength, lightweight fly ash ceramic has successfully come out, the performance indicators are better than the shale and clay ceramic. Which in addition to master the technical requirements, the additive is also the main reason affecting their performance. Admixtures including adhesives, bulking agent and mineralization agent. Different components of fly ash composition of its admixtures are not the same.

Fly Ash ceramsite production

Production of fly ash production process is as follows: raw materials (fly ash admixtures quantitative) - mixing mill - pellet - burning swelling - stacked - transportation (bagging) . Production of fly ash ceramic kiln should use binoculars, that the preheating and kiln drying section individually control its speed, so that state control of raw materials according to their warm-up time. Clay ceramic in recent years due to limited land resources, have been banned in some areas for production and use.

However, some areas can take advantage of river mud, mountain soil and other waste production. The process is: mixing material - granulation - Screening - sintering - stacked - transport (packing). Should be observed in operation, to prevent the agglomeration of the material in the kiln to affect quality.
