Introduction to the processing technology system of the jaw crusher production line

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Sand production line

Sand production line processing technologye

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Biosolids Technology Fact Sheet Gravity Thickening

Gravity thickener designs usually include circular tanks, 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter. The dimensions are based on prediction of settling due to gravity alone. To assist solids transport, gravity thickener bottoms are constructed with a floor slope between 1:6 and 1:3.

GRAVITY THICKENING OF ACTIVATED SLUDGE

2016-8-9  gravity thickening. Gravity thickening of sludge is defined as a process by which particles, or aggregates of particles of dilute sludge, due to their greater specific gravity, settle through water and concentrate.

Measuring Settling Rates and Calculating Thickener

2016-3-3  The required depth of the thickener may be ascertained by computing the capacity of the thickening zone to contain a supply of solids equal to the total capacity of the tank for the number of hours required to thicken the pulp to the density required in the discharge, and to this depth adding an allowance for the lost space due to the pitch of the drag in the thickener

A Critical Review of Thickener Design Methods t

The design method consists in measuring, in the labo­ ratory, the initial settling rate of a suspension with the concentration of the feed to the thickener and applying equation (6) to find the area S of the thickener. As we have already discussed, the concentration in the zone II of the thickener is not that of the feed
