The main structure of scrap crusher and waste aluminum crusher is basically the same, but the core difference lies in the screen, which directly determines the discharging effect, finished product quality and loss rate.
A. Screen selection of scrap aluminum crusher (for broken bridge aluminum/can/machine aluminum)
1. Material characteristics: aluminum is brittle and easily broken, so it is unnecessary to rub the ball for a long time.
2. Screen design: the screen holes are larger and more densely arranged.
3. Core purpose: discharging faster, avoiding the aluminum material from being crushed too much and producing too much aluminum powder, and reducing the loss.
4. Requirements for finished products: loose particles/flakes are enough, and it is not mandatory to rub into balls.
5. Selection formula: Macroporous dense mesh for aluminum crushing.
B. Screen selection of scrap crusher
1. Material characteristics: the steel has high toughness and hardness, which needs to be fully rubbed and compacted.
2. Screen design: the screen holes are smaller and the arrangement is thinner.
3. Core purpose: prolong the residence time of materials in the crushing cavity, repeatedly knead them into compact steel balls, and improve the specific gravity and selling price of finished products.
4. Finished product requirements: compact and spherical, with high specific gravity, which is convenient for storage, transportation and melting.
5. Formula of type selection: use a small hole and thin net for crushing steel, and rub it into balls to increase the specific gravity.
