Our CJ412 single toggle jaw crusher is engineered for even the toughest mining applications thanks to its heavy duty design Characterized by an attention to detail in its design and manufacture, this machine is an excellent choice when you need high production and low total cost The size of the nip angle of the jaw crusher has a great
α – nip zone angle, [o], which, from the scope of the press geometry, is con-stant regardless the rolls diameter. The value of pressure is increasing significantly in the nip zone, and rapidly de-creased when the compressed material leaves the press working chamber ( < 0). The
Feb 12, 2008· The nip angle describes the angle the stationary jaw plate and the pitman make with each other. The exact value of this angle isn't quoted or even determinable due to curvature in the jaws themselves but what is important is how wide vs. narrow it is. Wide nip angles can tend to expel material as the jaw closes as a large ball might squirt out ...
The experimental method to determine nip angles requires direct measurement of the normal stress at the roll surface and the roll angular positions during compaction using sensors located on the surfaces of instrumented rolls.6, 9, 11, 15, 16 For non-smooth rolls, however, normal stress measurement at the roll surface can be very technically challenging.

A radiographic study of the carrying angle in 422 patients demonstrated that the carrying angle increased with age, but there were no real differences in males and females. Apparent differences may be explained by increased joint laxity in females, permitting a greater degree of extension.
To find the real and imaginary parts of a complex number from its absolute value and angle, we multiply the absolute value by the sine or cosine of the angle: This results from using trigonometry in the right triangle formed by the number and the Real axis. Round your answers to the nearest thouh.
