[SOLVED] - HARD PARTICLES (AGGLOMERATES) FOUND IN POWDER MIX COMPOUND
Powder mix enters into shaft bearing assembly.
One pack stabilizer and lubricant are not properly mixed, and due to temperature, they form into hard particles.
Lower K-value resin or coarser particles.
Check to see that no powder is entered into bearing assembly. Ensure positive air pressure in the assembly or some leak-proof arrangement.
Change stabilizers and lubricants and also adjust the mixing temperature.
Check the resin K-value, change to higher K-value resin.
