Magnesium oxide dry granulation machine 2000kg

This equipment physically separates the material conveying area from the granulation area. The material is stably fed into the upper part of the granulation chamber through the conveying screw inside the box, rather than directly impacting the pressure roller. There is a support plate in the granulation room, with feeding holes on the plate, facing the pressing space of the pressure roller below. The key is that a pair of pre pressing plates that can move towards each other are set up to slide above the support plate. The "preloading space" formed between the two plays a key role in buffering and pre forming.

Workflow: After the powdered raw material falls into the pre pressing space, two pre pressing plates periodically approach each other to pre press the loose raw material; Subsequently, they move away from each other and release the pre compacted raw material clusters, allowing them to evenly and controllably fall into the pressing space of the lower roller through the feeding hole.

Automatic diversion and sealing fabric device

To ensure accurate introduction of materials into the pre pressing space, a rotatable and adjustable guide plate is installed above the pre pressing plate. Its uniqueness lies in the connection between the support column with elastic support and the support plate, which can adapt to the material flow rate, maintain dynamic fit with the lower structure, and prevent material overflow. The pre press plate itself is also designed with built-in baffles and springs to ensure a tight seal with the bottom of the guide plate, further preventing material leakage and scattering in non working areas.

Efficient granulation and precision grading system

Smooth crushing and material guidance

After the raw materials are pressed into thin sheets by a roller, they fall onto a tilted second guide plate and slide towards its lower end. Low end design has regular avoidance slots. A rotating crusher equipped with crushing teeth is located below it, and the crushing teeth can pass through the avoidance groove to efficiently crush the falling sheet material into primary particles. This design ensures a smooth crushing process, concentrated impact force, and reduces material splashing and excessive fine powder production.

Flexible granulation and precision screening

The primary particles first fall onto a sieve with a specific pore size. Above the sieve, there is an inclined whole grain roller, which forms a wedge-shaped gap with the surface of the sieve that gradually narrows from the inlet to the outlet. Under the gentle rolling of the whole roller and the vibration of the sieve, particles can be "round" and "trimmed" while ensuring that oversized particles are effectively crushed. Only particles/fine powders with qualified particle size and below can pass through.

Two level screening and finished product collection

The material passing through the * * sieve continues to fall onto a second sieve with finer mesh holes. Qualified finished particles cannot pass through the second sieve, but slide along the inclined sieve surface towards the finished product outlet for collection. The excess fine powder generated during the crushing and granulation process passes through the second sieve and is discharged separately from the powder outlet at the bottom, which can be recycled and reused, greatly improving the utilization rate of raw materials and the quality of finished products.

Technical advantages and benefits

High granulation quality: The pre pressing system ensures uniform density of the material entering the pressure roller, fundamentally solving the problem of uneven force on the roller. The resulting particle size distribution is more concentrated and the strength is higher.

More stable operation: The partition design of conveying and granulation effectively isolates the vibration and heat of screw conveying from the impact on the tablet pressing process, ensuring smooth operation and low failure rate of the equipment.

Excellent production efficiency: Smooth material flow and efficient integrated design of crushing, granulation, and grading reduce material blockage and rework, achieving continuous and efficient automated production.

High utilization rate of raw materials: The precision secondary screening system achieves efficient separation of finished products and fine powder, and the fine powder can be recycled, reducing material loss.

Easy operation and maintenance: Modular design and automatic adjustment function make the equipment easier to clean, adjust, and maintain.
