The amount of ball loading has a certain impact on the grinding efficiency. Less ball milling efficiency is low; too much ball loading will also make grinding efficiency low. Correct and reasonable ball loading must be calculated according to practical requirements. Can be calculated by referring to the following theoretical formula:
P=(π/4)·D2·L·ψ·Υ
Where: P-mill total weight of the ball, tons;
D—the effective inner diameter of the grinding machine, m;
L—milling cylinder length, meters;
Υ—the pseudo-specific gravity of the medium (ton/m3)
For forged steel balls: Υ = 4.5-4.8 tons / m3;
For rolled steel balls: Υ = 6-6.5 tons / m3;
For cast iron ball: Υ = 4.3-4.6 tons / m ³;
ψ—The media fill factor is %.
SMT Reflow Oven machine, The modified products are used in the electronics manufacturing industry to effectively improve product quality and production efficiency. Our reflow oven machine is the best choice for mobile phone, computer and electronic products factory.
Reinforced main hanging bracket to avoid rail deformation and board jamming
Multi-layer thermal insulation design. The Surface temperature of the Oven body is reduced by 10 to 20 degrees, reducing the temperature of the working environment effectively:
New cooling configuration to make the fitered or reclaimed air back to oven chamber, it can reduce the thermal loss as well as get better flux collection
15% heat transferring efficiency was improved to deal with the lead free process with more complicated and larger products,
The dual- rails conveyor is able to improve the production efficiency as well as save power and cost
Use the full protection of the sealed oven design to prevent nit
losing. So the lowest concentration of oxygen can be reached to 150ppm
Nitrogen consumption is only 20-22M /H with the oxygen level 300-800ppm
Nitrogen closed-loop control system is optional, energy saving and environmental protection
