Green stone disc granulator

The disc granulator (also known as the ball disc) is a volumetric metering feeding equipment that can evenly and continuously feed materials to the next process and can withstand large warehouse pressures. As a fine-grained material feeding equipment, it is suitable for transporting various non-sticky materials in powdery, granular or small state, such as coal powder, cement, clinker, limestone, shale, gangue, clay and other powdery, granular or small materials. Blocky materials. It can be widely used in gold processing plants, coal mining plants, chemical infrastructure and mechanized casting workshops for continuous, uniform and quantitative feeding and batching. This machine has a simple structure, convenient adjustment and excellent performance. This machine is suitable for conveying materials with a particle size not larger than 1. It is not suitable for conveying materials with high viscosity and difficulty in flowing and materials with particularly good fluidity.
.>Working Principle
.>Pre-add water to form balls, disc type full disc balling method. The raw meal powder is evenly moistened by atomized water in the twin-shaft mixer to form a pellet core with very uniform particle size, and then is sent to the pelletizing tray for pelletizing. The moisture content of the ball should be controlled at ~%. Most of the water should be added into the double-shaft mixer to form a ball plate, and only a small amount of supplementary water should be added. The amount of supplementary water should be controlled at about ~%. For dry powder granulation, the raw material pellet core is directly added to the pelletizing disk and sprayed with an appropriate amount of water. After entering the pelletizing disk, it moves along a parabola under the action of centrifugal force, friction and gravity. Due to the adhesiveness and plasticity of the material, the cores bond with each other and gradually grow during the movement. When the inclination angle of the ball plate, the speed of the edge of the plate, the moisture content and other parameters are constant, the balls of different particle sizes leave the edge of the plate and roll downward at different breakaway angles due to different gravity. During the continuous rolling process of the ball, the water in the ball is continuously squeezed out of the surface. Due to the adhesion of the material and the natural volatilization of the liquid film on the surface, the ball has a certain strength and then moves from the edge of the plate as the tilting plate rotates. The portion is discharged from the plate.
.>Performance Characteristics
.>It has the following advantages: high balling rate, rounded and strong particles, intuitive operation, easy maintenance, etc.
.>Disc granulator is a type of granulator. The disk of disc granulator is lined with high-strength fiberglass, which has the characteristics of uniform granulation, high granulation rate, smooth operation, sturdy and durable equipment, and long service life. It has many advantages and is an ideal granulation equipment.
.>Introduction
.>The granulating disc adopts an overall arc structure and the granulation rate can reach above. The granulating plate is equipped with three discharge ports to facilitate intermittent production operations, which greatly reduces labor intensity and improves labor efficiency. The reducer and motor adopt flexible belt drive to start smoothly, slow down the impact force and improve the service life of the equipment. The bottom of the granulation plate is made of multiple radiated steel plates to strengthen it, which is durable and never deforms. The thickened, weighted and solid base design does not require anchor bolts for smooth operation.
.>Working Principle
.>Various dry powder materials are added from the top of the equipment, degassed, spirally pre-compressed and transported to the arc-shaped slots of the two rollers. The two rollers rotate at the same speed and in opposite directions. The material bites into the groove and is forcibly compressed. After the material passes through the compression zone, the pressure it bears gradually reduces its surface tension and gravity, allowing it to naturally escape into the granulator and granulator for crushing and trimming, and then enters the vibrating screen for screening. Qualified products pass. The conveyor is sent to the finished product bin or directly packed into powdery sieved materials. The material under the screen is sent back to the raw material bin again through the return device for secondary roller pressing. The size of the extrusion force can be adjusted by the hydraulic system according to the needs of the particle strength. By changing the groove form of the roller surface, materials such as sheets, strips, olives, oblate balls, etc. can be obtained.
