Product details
Used for cooling high-temperature materials such as sintered ore, pellets, steel slag, blast furnace slag, etc. at 800-1500 ℃, and synchronously recovering waste heat.
1. Cylinder cooling machine (single cylinder/multi cylinder slag cooler)
● Structure: inclined rotary cylinder, supporting wheel, transmission, sealing, cooling air/water system
● Principle: The cylinder rotates with animal material flipping, exchanging heat with cold air/cooling water in reverse flow
● Temperature: 1000-1200 ℃ → below 200 ℃
● Characteristics: Simple structure, stable operation, and even cooling; Hot air can be returned to the kiln as secondary air
● Application: Cooling of rotary kiln clinker, steel slag, and slag
2. Grate cooler (reciprocating/pushing type)
● Structure: Fixed+movable grate, air chamber, fan, transmission mechanism
● Principle: The grate plate pushes the material forward, and the cold air at the bottom penetrates the material layer upwards for heat exchange
● Temperature: 1300-1400 ℃ → 100-150 ℃
● Features: fast cooling, high efficiency, and segmented temperature control; Hot air is used for waste heat power generation
● Application: Cement clinker, sintered ore, non-ferrous metal roasted sand
3. Circular vertical cooler (mainstream for sintered ore)
● Structure: Vertical cylinder, rotating fabric feeder, circular air duct, unloading device
● Principle: The material exchanges heat from top to bottom, while the cold air exchanges heat in reverse flow from bottom to top
● Temperature: 800-1000 ℃ → below 120 ℃
● Characteristics: Uniform material layer, low air to air ratio (about 1000m ³/t), high quality of waste heat (450 ℃+)
● Application: Cooling system for large sintering machines
4. Disc type slag cooler (slag specific)
● Structure: Multi layer rotating disc, water-cooled jacket, sealed shell
● Principle: The slag material disperses and flows between the disks, and indirectly exchanges heat with the disk surface
● Temperature: 800-1000 ℃ → below 100 ℃
● Features: Stepless speed regulation, sealed dust-proof, minimal wear, good waste heat recovery
● Application: Blast furnace slag, steel slag, fluidized bed boiler slag discharge
5. Membrane wall drum cooling machine (dry and efficient)
● Structure: Membrane wall heat exchange drum, closed circulation air system
● Principle: Indirect heat exchange, no material pollution, waste heat cascade recovery
● Temperature: 1000 ℃ → below 100 ℃
● Features: High efficiency, minimal dust, water-saving, heat recovery rate ≥ 60%
● Application: Dry quenching and cooling of steel slag and metallurgical solid waste, as well as waste heat recovery

We will uphold the spirit of precision engineering, leveraging its profound technical expertise and end-to-end service capabilities as core drivers.
Working principle: Integrating mechanical, hydraulic, electrical, automation and other technologies, the horizontal shaft is driven by an electric motor to rotate, and the eccentric sleeve is driven by gears to rotate, thereby driving the dynamic cone to make circular oscillations, achieving continuous extrusion and crushing of materials. The crushing chamber is optimized in design, and the crushing effect is not affected by liner wear.

Features: fully enclosed without leakage, precise measurement, anti hot air tempering, explosion-proof, DCS remote control. Application: Thermal power plants, circulating fluidized bed boilers, large industrial coal powder boilers.
Smelting equipment (blast furnace, converter, electric furnace supporting equipment)
Core positioning: The core equipment for coarse crushing of large materials is mainly used at the front end of the crushing production line to crush large raw materials (with a maximum feed particle size of 1200mm) to ≤ 80mm, laying the foundation for subsequent crushing processes. It is an essential front-end equipment for cement and mining production lines. Working principle: Adopting the principle of squeezing and crushing, the large pieces of material falling between the fixed jaw plate and the moving jaw plate are squeezed and crushed through the reciprocating biting motion of the two jaw plates, achieving coarse crushing processing. It is divided into two types: single elbow plate and double elbow plate. The single elbow plate model has higher production capacity and is suitable for high-yield demand scenarios. Core advantages: simple structure, convenient operation, long service life of wear-resistant parts, large crushing ratio, stable output, suitable for high hardness materials (such as limestone and iron ore), low maintenance cost, suitable for various types of production lines from small to large. Adaptation scenarios: coarse crushing of raw materials in cement production lines, coarse crushing in mining, raw material crushing in sand and gravel yards, coarse crushing in construction waste recycling, etc. Corresponding images (high-definition without watermark, available for direct image search): actual photos of the entire jaw crusher, close-up shots of the jaw crusher feed inlet, jaw crusher mining site, and details of the jaw crusher transmission device.
