PLC fully automatic control system operation console

Overview: Fully automatic batching system and advanced high-speed mixing equipment for batching and mixing to ensure the accuracy and uniformity of batching; regular automatic feeding and spray water addition to ensure the uniformity and smoothness of semi-finished granules; advanced ceramsite firing The process and timely temperature monitoring system ensure the accuracy of the length of the firing zone and the firing temperature, so that the ceramsite can fully react and sinter at the appropriate temperature. The entire production line is simple, precise, efficient and environmentally friendly, providing a strong guarantee for the production of high-quality ceramsite sand.

Crushing process equipment - full jaw crusher

Description: The headset crushing system composed of jaw crusher and hammer crusher is used to crush the raw ore to be crushed into particle size ≤10mm.

Grinding process equipment

Description: Grind the crushed materials into particles with a particle size of ≥400μm

Ingredients process equipment

Description: After the mixer is fully stirred and evenly mixed, it is sent to the granulator by the conveyor belt through the quantitative feeder.

Ball making process equipment

Description: Water atomization and raw materials are uniformly stirred and homogenized in multiple large containers of granulators for 10-15 days, and then the balling machine is used to form balls naturally. The diameter of the balls is 20μm-140μm:

Screening process equipment-double-layer cylinder finished product screen, double-cylinder double-layer semi-finished product screen.

Description: According to the demand, it will be screened in the first level according to the particle size specifications. Those that meet the specifications will go to the next step to the semi-finished product warehouse, and the rest will continue to be homogenized.

Calcining process equipment-3.3*60m rotary kiln

Description: After the semi-finished products arrive at the semi-finished product warehouse, they are transported to the rotary kiln for calcination by belts and feeders. Control the temperature of the rotary drying kiln at 140°-400°, dry and preheat the pelletized raw materials with high moisture for 20-40 minutes, and conduct secondary screening of the dried pelletized raw materials to separate the finished products. Sieve to the next step for calcination, continue homogenizing those that do not meet the specifications, and return to the previous step. Calculate the finished product, the calcination time is 1-3 hours, and the temperature is controlled at 1300℃±50℃

Cooling process equipment-single cylinder cooling kiln

Description: The calcined finished product is transported to the rotary cooling kiln. It is air-cooled first. After the temperature drops to 1200-700, it is then watered and cooled until the temperature drops to 700-40°:

Packaging process equipment-automatic packaging machine

Description: The cooled finished products are sent to the finished product screen by the elevator for three-stage screening. The finished products that meet the specifications are screened as needed, and the products that do not meet the specifications continue to be homogenized. Finished products that meet the specifications are transported to the finished product warehouse by belts, where they are automatically packaged and assembled.

Environmental protection process equipment (special environmental protection equipment for desulfurization and denitrification)

Production process flow chart

Various raw materials enter the factory→crushing→homogenization of raw material bins (automatic batching system mixes raw materials and auxiliary materials according to formula ratio)→grinding by ball mill→powder selection by powder concentrator (real-time monitoring to ensure powder quality)→homogenization of mixed powder→ Transmission system → Granulation system → Screening system → Semi-finished product testing (if qualified, go to the next process; if unqualified, go to the granulation system) → Semi-finished product storage → Semi-finished product drying (dry excess moisture in the semi-finished product) → Rotary kiln calcination (real-time monitoring Ensure product quality)→Finished product screening→Finished product full index testing→Packaging→warehousing→sales.

Ingredients: Mix raw materials of different types and proportions together according to the requirements of the product.

Grinding: Grind the mixture obtained during the batching process to make it finer and more uniform.

Ball making: The ground material is made into a spherical shape for better heat treatment during the burning process.

Calcining: Put the prepared spherical materials into a high-temperature furnace for heat treatment to make ceramsite sand

Natural gas preparation: Natural gas needs to be used as fuel during the tender burning process, so natural gas needs to be prepared.

Cooling of finished product: Generally, the fired ceramsite sand needs to be cooled.

Screening: Screen the cooled ceramsite sand to remove unqualified particles and obtain ceramsite sand products that meet the requirements.

Packaging: Pack the screened ceramsite sand
