Features
It comprises 1~4 hollow cylinders sealed at one end, for pellets having a particle size between 4 and 14 mm, the inner diameter of the cylinder is 200 ±1 mm, and the effective length is 154 ± 1 mm; for pellets with a particle size between 25 and 50 mm, the inner diameter of the cylinder is 400 ± 2 mm. The cylinder is made of stainless steel (Z2CN18-10) with thickness not less than 3 mm. They are mounted on two horizontal axes and each cylinder can be used for one test. There should be no bulge in the interior of cylinder caused by welding or fixing. Seal the cylinder with a 8mm-thick flat cover. The sealing is ensured by seam on the flat cover.
The abrasive is consisted of stainless steel round balls with diameter of 10 ± 0.5 mm. Let the ball pass through two parallel bars with a pitch of 9.5 mm, the weight cannot be less than 34 grams). The electric motor (approximately 1 KW) should ensure that the cylinder can rotate at a constant speed of 100 r/min ±5 rpm and the brake can automatically stop the motor after one test.
