Live Chat2018822Recently I received from Sieg an evaluation sample of a new product the U1 Vertical Horiontal mill. Vertical mills since the 1950s or so have become much more common than horiontal mills but it wasnt always that way. The horiontal mill was developed first and for many years was a workhorse machine found in many machine shops.

Live ChatThe energy needed for the production of 1 ton of lead oxide is fairly constant when the mill operates at between 55 and 90 of its critical rotation speed. The critical rotation speed is assumed to be the speed of drum rotation at which lead pieces stick to the drum walls under the action of centrifugal forces and do not rub against each other.
