The Hydrocyclone have blessings and disadvantages?
Hydrocyclone has several advantages: easy structure, no moving parts; processing capability per unit volume; sand laundry equipment high classification accuracy; low value of equipment; occupied, straightforward maintenance; sand mining equipment less the quantity of keep and time of pulp within the machine.
Hydrocyclone shortcomings: transport the slurry with the sand pump consumes power; sand pump wear violent and out of the feed gap, thus frequent repair; needs to the ore particle size, mobile sand laundry plant pulp density and pressure changes within the scope of tiny, simply cause the standard of classification fluctuations. Strictly to strengthen the operating system, most of the cyclone affecting the standard of shortcomings are often avoided and reduced.
For example: 250 hydrocyclone Park tube diameter of 250 mm.
Section III classification method factors
the main factors affecting the classification process?
Factors affecting the classification method. Ore properties: clay content and grain size of the proportion and form of the ore into the grading machine materials: machine construction factors: the scale of the helical axis of the trough tilt angle rotation speed, the width of the trough, the operating The factors are: pulp density, uniformity to the number of ore to mine, the amount of the overflow weir.
When the clay content within the graded material or fine grade the a lot of slurry viscosity the bigger, and therefore the smaller the settling velocity of mineral particles within the pulp, and therefore the overflow product size conjointly thicker. Materials containing clay less or when desliming, so as to avoid the entrainment of sand returning an excessive amount of fine-grained level, ought to be graded concentrations of an applicable increase.
the proportion of graded materials completely different of various sizes and ore particle form different classification?
The same concentration and different operating conditions, if the smaller the proportion of graded materials, the bigger the viscosity of the slurry particle size within the overflow product thicker, increase in content of fine particles within the come sand. within the classification of the big proportion of the ore ought to be properly increase the concentration of grading; grading the proportion of tiny ore, ought to be an applicable lower classification levels.
When the ore particles are flattened form, settling velocity slower than spherical or near the park-shaped ore settling velocity, and therefore lower the concentration of flat ore grading, or to accelerate the speed of discharge of the overflow product.
