[0056] Step 1. Abrasive crushing
[0057] Set the density to 1.4g / cm 3 , with a hardness of 450HB and a thickness of 5mm, amino molding compound blocks (thickness is 3-10mm, granular raw materials with a particle size greater than 3mm can also be used) are put into a blade plastic crusher for crushing, and the fixed blade of the crusher 4 pieces, 6 moving blades, the adjustment gap between the control blades is 4mm, and the screen aperture is Ø6.0mm.
[0058] Step 2. Abrasive crushing and screening
[0059] Use a turbo mill with a rotor diameter of 500mm and a screen aperture of Ø1.5mm to crush the amino molding plastic particles crushed by the crusher, and then put them into a vibrating screen for grading and screening. The particle size levels after screening are 50 mesh.
[0060] During specific implementation, according to the raw material situation, steps 1 and 2 can be combined, the same below.
[0061] Step 3, abrasive preparation
[0062] The screened 16~20 mesh, 2...
example 2
[0067] Step 1. Abrasive crushing
[0068] Set the density to 1.5g / cm 3 , with a hardness of 420HB and a thickness of 3mm, the amino molding compound is put into a blade plastic crusher for crushing. The crusher has 2 fixed blades and 3 moving blades. The adjustment gap between the control blades is 2mm, and the screen aperture is Ø10mm.
[0069] Step 2. Abrasive crushing and screening
[0070] Use a turbo mill with a rotor diameter of 350mm and a screen aperture of Ø2.0mm to crush the amino molding plastic particles crushed by the crusher, and then put them into a vibrating screen for grading and screening. The particle size levels after screening are 50 mesh.
[0071] Step 3, abrasive preparation
[0072] Put the 20~30 mesh, 30~40 mesh, and 40~50 mesh amino molding compound particles obtained by screening into the ball mill according to the mass percentage of 40%, 40% and 20% and stir for 10 minutes to make the particles fully and evenly mixed. Get a polishing abrasive.

[0077] Step 1. Abrasive crushing
[0078] Set the density to 1.6g / cm 3 , the hardness is 400HB, and the thickness is 10mm. The amino molding compound is put into the blade plastic crusher for crushing. The crusher has 3 fixed blades and 5 moving blades. The adjustment gap between the control blades is 6mm, and the screen aperture is Ø8. 0mm.
[0079] Step 2. Abrasive crushing and screening
[0080] Use a turbo pulverizer with a rotor diameter of 750mm and a screen aperture of Ø2.5mm to pulverize the amino molding plastic particles crushed by the crusher, and then put them into the vibrating screen for grading and screening. The particle size levels after screening are 50 mesh.
[0081] Step 3, abrasive preparation
[0082]Put the 16~20 mesh, 20~30 mesh, 30~40 mesh, 40~50 mesh amino molding compound particles obtained by screening into the ball mill according to the mass percentage of 20%, 40%, 30% and 10% and stir for 20 Minutes, the particles are fully and uniformly mixed...
