Product Description:

The potassium sulfate fertilizer dry granulation production line is a production process that uses mechanical pressure to process dry powder materials to obtain granular products.The main pelletising machine is a dry dry press granulator. The following is a detailed introduction to the production line:

Production line composition and workflow:

1. Raw material processing

- Dry powder materials, such as potassium sulfate and compound fertilizers, are transported to the raw material bin of the elevator by screw conveyors, belt conveyors or manual handling.

- The bucket elevator lifts the raw material powder to the vibrating transition bin, using vibration to disperse the material and avoid agglomeration.

2. Quantitative feeding

- The quantitative feeder adopts variable frequency speed regulation technology, which can accurately control the amount of material added to ensure the stable operation of subsequent processes.

- The forced feeding spiral feeding hopper further degasses the material and feeds the material into the tablet press by pressure.

3. Tablet forming

- The tablet press consists of left and right fixed bearing seats and sliding bearing seats, a frame structure, two alloy steel rollers, two hydraulic cylinders and an electric automatic pump station, as well as a special reducer for hard tooth surface and a main motor.

- Pairs of rollers with holes rotate in opposite directions at the same speed. One set of roller bearing seats is stationary in the frame, while the other set moves on the frame rails, and is pressed against each other by hydraulic cylinders.

- Dry powder materials enter between the two rollers continuously and evenly from above the two rollers by their own weight and forced feeding. They first flow freely, and then are gradually bitten into the trough by the rollers after entering the bite area. With the continuous rotation of the rollers, the materials are gradually compressed into pieces, and then fall off the holes due to elastic recovery and self-weight, and enter the crushing and screening device.

4. Crushing and granulating

- The crushing and granulating machine consists of a crushing box, a crushing spindle, and a special rotating blade to form a crushing and granulating chamber. The motor drives the spindle to rotate at high speed to crush and granulate the extruded materials.

5. Screening and packaging

- The vibration grading screen is equipped with an anti-blocking net device, which is convenient for cleaning the screen and can screen the crushed and granulated materials into granular qualified products and recycled powder.

- Qualified granular products are weighed and packaged, while the sieved powdered materials re-enter the feeding port of the elevator through the return screw, and are mixed with fresh materials and added to the pre-feeding hopper to enter the next round of process flow.

Process characteristics:

1. No additives required: the material is compressed and formed by mechanical pressure without adding any wetting agent, which ensures the purity of the product.

2. Short and efficient process: dry powder is directly granulated without subsequent drying process, the process flow is short, energy consumption is low, and auxiliary equipment and personnel are less.

3. Controllable particle strength: by adjusting the pressure of the hydraulic cylinder, the strength of the finished particles can be controlled to meet different usage requirements.

4. Environmentally friendly and closed: the system is closed and circulated, which reduces dust pollution, improves labor operating conditions, reduces powder waste and packaging costs, and improves product transportation capacity.

5. Wide range of application: not only suitable for potassium sulfate fertilizer, but also can be used for granulation of various powder materials, such as zinc oxide, calcium phosphate, etc.

Customization:

A Chinese potash fertilizer company has introduced an advanced dry roller granulation production line to achieve large-scale production of fertilizers. After adopting this equipment, the company's production capacity has been greatly increased from the original 50,000 tons/year to 150,000 tons/year. At the same time, product quality has been significantly improved, and the product qualification rate has reached more than 98%. This is due to the precise process control and stable equipment performance of the dry roller granulator, which can produce MOP fertilizers with uniform particles and high strength. The company's products are very competitive in the market, not only meeting the needs of domestic agricultural production, but also exported to many countries and regions.
