The roll crusher Selection Guide:
To select a pair of rollers according to the user to provide the volume of the block was broken material, production and crushing fineness or four roll and grind roll diameter, the width of the rolls, the form of a roller surface, protected mode, and ultimately determine the model of the roll crusher.
, Rolls, a choice of four roller
, Crushing fineness was broken material block sizes based on user provided to select a pair of rollers or four-roll model. When the proposed use of roller crusher crushing ratio does not exceed 15; recommended to use a four-roll crusher crushing ratio is more than 15.
Note: crushing ratio = feed blocks (broken material) volume ÷ discharge finished materials (crushed).
Second, the choice of the diameter of the rolls
|
被破物料體積（ mm ） Broken volume of material (mm) |
60以下 Below 60 |
80以下 Below 80 |
100以下 Below 100 |
120以下 120 and below |
150以下 150 or less |
|
輥筒直徑 Roll Diameter (mm) (Mm) |
600 600 |
800 800 |
1000 1000 |
1200 1200 |
1500 1500 |
Third, the choice of the width of the rolls
Calculated based on the right of formula: B = T ÷ (D x R x M x 11305)
B: The rolls width T: indicates the total output D: indicates the diameter of the rolls
R: was broken crushing fineness M: the material gravity (11305): said the calculation of the coefficient
Selection of the roll surface
1, a crushing particle size of less than 3 mm when the choice flat roll surface.
2, the broken particle size greater than 3 mm optional cone welding roller surface.
3 require crushing the finished material after the particulate, powdered small, selected gear rolls.
A require crushing the finished feed size is greater than the the 30mm selection wolf tooth surface.
B, requiring broken after the finished feed size less than 30mm, larger than 8mm selection occlusal tooth surface.
