Using Principles of Construction Chute
Spiral chute separator or construction chute for ore are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity,centrifugall force and other forces in the fluid medium.It has extremely good performance and effects in processing placer of beach,riverside,seashore and stream.Ganye Spirals used in ore beneficiation are made of polyurethane lined fiber glass with wearable corundum inner surface.
The spiral chute is an advanced equipment that can keep lump coal from being stricken into pieces. The aim can be achieved that to increases effectively the lump coal rate by to limit the coal flow to move spirally through the chute instead of free-fall motion. The purposes of the entire design are the speed of impact point is as low as possible while it runs smoothly in the whole process and ensuring that no half-way down coal until the coal supply ends.
Raises up the spiral chute, calibration perpendicular line, than fix with the iron stand or the wood in the appropriate position, delivers by the sand pump the ore on the screw to go against two feed heads place, joins the make-up water, the adjustment ore oar density, the ore oar nature from the high downward eddy, so has one kind of inertia centrifugal force in the revolving incline speed of flow, through the eddy gravity and the centrifugal force function, separates the ore and the granulated substance, the ore concentrate inflow ore concentrate fights with the pipeline leads, and used the sand pump platoon to walk again, has completed the dressing entire process.
Spiral chute having been successfully studied by Beijing General Research Institute of Mining & Metallurgy, glass steel spiral chute is high-efficiency reelecting new equipment of the international advanced standard. It is used to separate the iron, stannum, tungsten, tantalum, niobium, gold ore, colliery, monazite, retiles and zircon of the size between 0.3 and 0.02 mm, and the other metals and nonmetal minerals of enough proportion deviation. china cone crusher:http://www.hx-crusher.com/cone_crusher.html

In addition, no coal accumulates in the chute if there is no more coal to transport. Because the bottom of the whole chute is an undevelopable surface, and all of the parameters including width, spiral angle and tilt angle are continuously variable for the purpose of controlling speed and direction in one segment. It is so complicated that it is almost impossible to get all of thereasonable parameters in every point, or to get its view or to draw the developing drawing by traditional drawing method. For this reason, we developed a special software commissioned by Hongxing Mining Machinery Co., LTD.
The software can give these important parameters of parts, such as the width, spiral angle, tilt angle, acceleration, speed, and the variation of each parameter and so on according to coalsituation (different coals, different humidity, different grain size), and coal storage conditions (diameter, height). In this article, we first study the movement rules of coal in chute, create amechanical model and introduce of coal flow in the chute in the run-time kinematic equation.
Secondly according to the requirement to make sure the coal flow moves through the chute at a constant speed we calculate the parameters of the standard segment; thirdly we could have the parameters of the non-standard segment based on the speed and the state of the coal. So a series of the boundary equations for not only the standard and non-standard but also the interior and exterior panels of the spiral chute are derived.
As the professional manufacturer of complete sets of mining machinery, such as vibrating feeder, Henan Hongxing is always doing the best in products and service.
