Second mixer type and use

Clay sand sand mixer can be mainly divided into grinding wheel sand mixing machine, pendulum wheeled sand mixing machine, grinding wheel rotor type sand mixer and the rotor type sand mixer four categories.

Clay sand sand mixer determination of productivity and the Numbers

There are two kinds of calculation method of sand mixer productivity: - one is according to all the sand mold size and quantity calculation of each sand requirements throughout the year; Second is the largest sand requirement calculated hour. For mass production of foundry sand mixer total productivity per hour to meet the highest number of modelling calculation per hour, that is to say, sand mixing machine should be greater than the total productivity per hour biggest sand molding line hour requirements. Compute the sand mixer, therefore, more appropriate overall productivity per hour.

(1) calculation of quantity of sand molding line hours the most helpful

E = 1 _ lnyK

Type e a sand molding line hours the most helpful in quantity (t/h);

1 a sand box frame length (m);

8 a sand box box width (m);

Ff a sand box up and down the total height (m);

A model line hours maximum number (junction/h) l shape

Y a molding (loose) packing density (t/m3), take 0 _9 - l. lt/m3;

K a compaction coefficient (K value; take 1, 25-1.35 low pressure molding, high pressure take shape

1 l65, gas and the shape and static pressure taking 1.6 1.65);
