It also provides customers with general contracting services, including preliminary research and consulting, engineering design, bidding consulting, equipment supply, installation, commissioning, etc. At present, it has provided products or services to a large number of customers and has been widely praised.

1. The single-cylinder rotary kiln is used to control the heat preservation and calcination process. The equipment runs smoothly, the power consumption is reduced, the equipment reliability is good, the energy consumption is 30% lower than that of ordinary kilns, the production capacity is increased by more than 40%, the energy is recycled, the process design is reasonable, and the overall technical level is in the world's leading position.

2 Provide customers with advanced equipment process customization solutions and equipment selection solutions based on their different product requirements (particle size, strength, density and production scale).

3 It can produce 20-40 mesh high strength, medium density, 40-70 mesh high strength medium density and over 70 mesh high strength medium density products.

4From equipment process selection and design to the entire plant layout design, we fully meet customers' special requirements and ensure the practicality and economy of the production line.

5. Use advanced exhaust gas treatment equipment to keep the flue gas concentration below 20mg/Nm3.

6 The production line is equipped with temperature and pressure monitoring instruments, the operating parameters are displayed by computers, and advanced computer control can be used to achieve automatic operation of the entire system, saving 60% of labor costs for customer factories.

1. Crushing. The particle size of bauxite in the mine is about 300~500mm, with low moisture content. After being crushed by jaw crusher and hammer crusher, the particle size of bauxite is about 25mm.

2. Adding chemicals. Additional materials such as bauxite and manganese powder are transported to the belt conveyor through a belt scale to determine the appropriate ratio. When the moisture content of bauxite or other materials exceeds 6%, they must be dried first.

3. Grinding. In the grinding process, the main equipment is the ball mill and separator, which form a closed-circuit grinding system, and the material particle size is required to be less than 300 mesh.

4. Granulator. The ground raw material powder is stored in a hopper, usually 2-3 hoppers, which can be unloaded individually or in combination with multiple hoppers. The raw material powder enters a small silo, which is equipped with a spiral metering device or a belt scale. The material is transported to the granulator, and water is sprayed to the granulator through a pipeline pump. When the granulator rotates, the raw material can be made into ceramic raw sand of various particle sizes, which is transported to the rotary kiln by a belt conveyor. Qualified sand is calcined in the rotary kiln, and oversized sand is returned to the raw material grinding process. The granulation system is fully automatic and continuous, and is equipped with a bag dust collector to purify exhaust gas.

5. Calcination. Ceramic raw sand is calcined in the rotary kiln. As the rotary kiln rotates and tilts, the calcined ceramic sand moves toward the kiln head. At the same time, coal powder is sprayed from the kiln head into the kiln head burner. The ceramic raw sand is calcined into high-strength ceramic sand in the rotary kiln.

6. Preparation of coal powder. Coal powder is prepared by ball mill or vertical mill, and the hot air from the kiln head is used to dry the coal powder. The fineness of the coal powder can be adjusted at will by using a separator; it provides sufficient conditions for the full combustion of the coal powder.

7. Cooling of finished products. Ceramic sand is generally cooled by a rotary cooler, which is simple and reliable. The secondary air of the cooler absolutely enters the kiln, and the multi-channel burner can save a lot of energy. The temperature of the cooled ceramic sand is very low and can be touched by hand.

8. Screening. After passing through the cooler, the ceramic sand can be directly transported to the multi-stage vibrating screen and can be divided into multiple particle levels as required.

Ceramic sand specifications

Model 1: 0.45-0.9mm (20 mesh-40 mesh) high strength medium density

Model 2: 0.9-1.25mm (16-20 mesh) high strength medium density

Model 3: 1.0-1.70mm (12-18 mesh) high strength medium density

Model 4: 0.224-0.65mm (40mesh-60mesh) high strength medium density

9. Packaging. The sieved ceramic sand is transported to different silos, which are connected to the packaging machine, and the finished products are transported to the warehouse for stocking. Each dust point in the process needs to be equipped with a dust collector to purify the exhaust gas.
