Large particle production equipment
The disc granulator has a wide range of applications and its advantages are as follows:
1. No drying process, granulation at room temperature, one-time molding, low investment, quick results and good economic benefits.
2. Low power and reliable operation, no three wastes discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology and low production cost.
3. The raw material adaptability is wide, and it can be used for granulation of various raw materials such as compound fertilizers, medicine, chemicals, feed, coal, metallurgy, etc., and can produce compound fertilizers of various concentrations and types (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.).
4. In particular, the granulation of rare earth, ammonium carbonate and ammonium sulfate compound fertilizers is a promotion project of applicable technologies for national environmental protection.
The granulation disc adopts an overall arc structure, and the granulation rate can reach more than 93%. The granulation disc is equipped with three discharge ports, which is convenient for intermittent production operations, greatly reduces labor intensity and improves labor efficiency. The reducer and the motor are driven by flexible belts, which start smoothly, reduce impact force and increase equipment service life. The bottom of the granulating plate is reinforced with multiple radiating steel plates, which is durable and will never deform. The thickened, heavier and sturdy base design does not require anchor bolts for stable operation.
Disc granulator is a type of granulator. The disc is lined with high-strength fiberglass. It has the advantages of uniform granulation, high granulation rate, stable operation, durable equipment and long service life. It is an ideal granulation equipment.
Various dry powder materials are added from the top of the equipment, degassed, spiral pre-compressed and conveyed to the arc-shaped notch of the two rollers. The two rollers rotate at the same speed and in opposite directions, bite the materials into the groove and compress them by force. The pressure on the materials after passing through the compression zone gradually decreases, and its surface tension and gravity make it naturally escape, enter the granulator and granulator for crushing and trimming, and then enter the vibrating screen for screening. Qualified products are sent to the finished product warehouse or directly packaged through the conveyor. The powdered materials under the screen are sent back to the raw material warehouse for secondary rolling through the return device. The size of the extrusion force can be adjusted by the hydraulic system according to the needs of particle strength. By changing the groove form of the roller surface, flake, strip, olive, flat ball and other materials can be obtained.
The disc granulator is composed of a large disc, a large gear, a transmission part, a frame, a base, a scraper frame, a non-powered scraper, etc.
① The main body of the disc granulator, which includes the frame, the adjustment part and the granulating disc and other structures;
② One main reducer, the input shaft is equipped with a pulley, and the output shaft is equipped with a small gear;
③ One main motor, equipped with a pulley;
④ Supporting the granulating disc device, including a main shaft, two sets of roller bearings, and two bearing seats;
