Shijiazhuang Naipu Pump Co.,ltd is a professional manufacturer of all type of horizontal centrifugal slurry pumps. Our horziontal centrifugal slurry pumps including:NP-AH,NP-AHR,NP-HH,NP-M which are designed for handing highly abrasive,high density slurries in the metallurgical,mining,coal,power, building material and other industrial department,etc.The pumps of this type also maybe installed in multistage series.
NP-G,NP-GH gravel and sand slurry pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. they are suitable for deliverying slurries in mining.Explosive-sludge in metal melting,dredging in dredger and course of rivers,and other fileds.Type NP-GH pumps are of high head ones.
NP-Lseries pump are suitable for delivering lower abrasive,lower density slurries for metallurgical,mining,and building material departments.The shaft seal adopt gland seal and centrifugal seal.
And Naipu also produce many other types of Horizontal slurry pumps,such as NP-M,NP-ZG,NP-WS dredging pump and NP-ZJW Feeding Pumps,etc.

Granulators are extensively utilized across various industries, particularly in the production of organic and compound fertilizers. Among the popular types of granulators are drum granulators, disc granulators, and roll extrusion granulators. Of these, disc granulators and roll extrusion granulators stand out as the most commonly adopted options for creating organic and compound fertilizers.
The disc granulator operates with an integrated spindle and disc setup, either on an inclined or flat plane. During production, a spray device is positioned above the disc to regulate the moisture levels in the raw materials. Connected directly to the motor via a reducer, this setup ensures smooth startup, minimizes shock, and extends the lifespan of the equipment. Reinforced with multiple radial steel plates, the granulation disc boasts durability and resistance to deformation. Its thickened and weighted base design allows for seamless operation without the need for anchor bolts. The disc granulator is known for its simple yet robust structure, high efficiency, ease of maintenance, and consistent pellet size. Raw materials enter the disc at a steady pace and form spherical particles due to gravity and centrifugal force. This type of granulator is reliable, energy-efficient, and offers excellent performance with minimal downtime.
On the other hand, the roll extrusion granulator is considered a versatile option in fertilizer production. Structurally, it comprises three main sections: granulation, crushing, and screening. Built with a carbon steel frame, the extrusion rollers are crafted from specialized wear-resistant materials like 20 chromium manganese titanium. This model excels in terms of affordability, consistent output, and adaptability to different types of organic and compound fertilizers. Notably, it bypasses traditional steps such as drying and cooling, making it a practical choice for smaller businesses.
The drum granulator stands out with its unique features, including a special rubber lining or acid-resistant stainless steel lining inside the cylinder. These linings automatically remove scars and tumors, eliminating the need for a traditional scraper device. This granulator produces pellets with high strength, excellent surface quality, and impressive corrosion and wear resistance. Additionally, it is energy-efficient, durable, and user-friendly. Inside the drum, steam, gas ammonia, or solutions like phosphoric acid and nitrogen can be added to facilitate chemical reactions and heating during granulation. Alternatively, the process can involve cold granulation with minimal water supplementation. As the material rotates within the drum, it adheres together at specific humidity and temperature conditions, forming uniform pellets.
In summary, each granulator type—disc, roll extrusion, and drum—offers distinct advantages tailored to different applications and operational preferences. Whether you’re looking for cost-effective solutions or advanced technology, there’s a granulator that fits your needs.
