As far as endmill size goes do you always go as big as you can go i am doing some parts now that i have always used a 12 endmill on but i am wondering if i would be money ahead using a 1 endmill.I figure i can probably go faster, deeper cuts, and less spindle wear because i am going.Get Price

The efficiency of a mill is directly proportional to power consumption for equal coarseness of the initial material and the product.Material with a particle size of up to 30 mm is handled by ball and rod mills self-grinding mills are suitable for particle sizes up to 300 mm.The particle size of the product may be less than 0.04 mm.Get Price
In turn, this leads to a higher rock to ball ratio, resulting in insufficient grinding energy and a further increase in load inside the mill.Pebbles flow-back similar to slurry flow-back, the pebbles flowing back into the mill increase with larger pebble port or grate slot size.Get Price
When the feed drops into the crusher, the mantle squeezes the rock against the concave surface.When the mantle moves away and the rock drops down further and subject to additional crushing during the next cycle.Material exits the crusher through the open side setting.Thus, the top size of the product is determined by the open side setting.Get Price
