According to the research on the kinematic characteristic curve of the Haoxing mineral processing technology expert, the kinematic characteristic curve of the shaker can be depicted by the actual measurement method or the graph algorithm. The actual measurement method is to connect the displacement and velocity sensor to the shaker, and directly depict the displacement of the Haoxin beneficiation technical expert through the oscilloscope. Through the study of the motion characteristic curve of the pair, the motion characteristic curve of the shaker can be depicted by the actual measurement method or the graph algorithm. The actual measurement method is to connect the displacement and velocity sensor to the shaker, and directly plot the displacement, velocity and acceleration curves through the oscilloscope. The graph algorithm is based on the geometrical relationship of the parts in the bed head. It is used as the map to first obtain the displacement curve, and the function approximation method is used to establish the mathematical model, and then the velocity and acceleration equations are further derived and plotted.
The differential motion of the shaker motion is mainly reflected in the acceleration of the transition period of the front and rear movements, so it can be assessed by the time required to run the same distance. The two asymmetry coefficients j5}l and E2 are often used as criteria.
E1=(the first half of the bed forward + the second half of the back) The time required / (the second half of the bed forward + the first half of the back) = t1/t2
The second half of the bed surface requires rapid deceleration and rapid reentry, while the second half of the retreat is a slow return, so always t1>t2, E1>1. When E2>1. It means that the process time in front of the bed is long, the back time is short, and the possibility of the particles sliding backward is reduced. E1 is compared with E2, and E is the strength of the bed surface for quick return movement, so it is more important than E:. In the selection of coarse, ore, E1 = 1.88, E2 = 1, select fine ore E1 = 1.88, E2 = 1. 24 is more appropriate. If both E1 and E2 are equal to 1, the displacement curve becomes a sinusoid and the particles only oscillate in place.

High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.
High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".
This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.
The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.
Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.
The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
