Organic fertilizer granulator machine
: most of the structure of the disc granulator: each machine is composed of components such as a flow bracket, a sorting disc, a sports frame, an ore receiving slot, a feeding slot, and a developing heat pipe. The selection disc is actually a circular table with a degree of taper of l: 0.02. The disc is supported on the motion frame through the core shaft, and there is another circular track on the bottom surface, which is stuck on the supporting roller. The revolving weight and the electric effect and its transmission elements are installed on the sports frame. The sports frame is made of pure steel hoisting on the flow bracket. When the electric effect rotates, the idler pulls the disc to rotate in a 6.5 second turn , Rotate the heavy hammer with a progress of 300 to 400r / min, so that the disk surface shakes in response to the progress.
The task principle of the disc granulator: each machine and the cross-flow transmission belt chute are conceived using Bagnold shear practice and the flow film mining principle. When the slurry is given from the core of the disc to the primary selection area of the disc surface, the slurry is on an inclined surface Moving upwards, the ore group is affected by the flow force and the shearing force caused by the heavy hammer, and the stratification and classification will soon stop. The yield of heavy ores with large particle size and density will first settle on the vertical surface; Heavy minerals and light minerals with large particle size and small density are sinking in the lower part of the vertical plane; light minerals with small particle size and small density are not able to settle and flow to the tailings connection mine. The minerals of various nationalities sinking in the primary selection area were brought back to the selection area by the rotating disc, and were repeatedly washed by the developing water, so that all secondary light minerals flowed to the medium mine slot, and the dense heavy minerals flowed to the fine Mine to mine slot.
The use characteristics of the disc granulator:
(1) Each machine adopts a heavy hammer installed on the motion frame to shake the selection surface with high frequency rotation, and successive track-type circular activities occur to strengthen the shearing effect of the liquid flow. Moreover, this kind of circling shear force is directional, and can lose a strong evacuation pressure, so that the ore particles are constantly turning on the disk surface, thus slowing down the grading and settling progress of the ore particle group on the disk surface. Improve the quality of the goods and solve the power.
(2) The sorting surface of each machine is a conical surface, which gradually increases from the feed end to the discharge end. When the pulp is given to the sorting surface, the speed of light of the pulp quickly decreases, and the thickness of the ore layer quickly becomes thin The heavy mineral deposits are displayed from coarse to fine. After entering the selection area, the developer water scatters towards the winding position. The coarse-grained minerals in the upper part are washed down and then settled in the lower part, so that it has two development opportunities above, and the fine-grained items in the collapsed part are once. Indirect flushing to the concentrate trough is beneficial to coarse-grain-level improvement of quality and fine-grain-level recovery.
