A process for making acid-activated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower ...
just above the jig body, and re-tighten the pin. Clamp Pad Adjustment For a fi rm hold on the workpiece, you may have to adjust the position of the clamp pad. To do so, release the lock-nut, rotate the clamp pad in or out, and test the hold by depressing the toggle. Repeat this process until you get a secure hold on the workpiece. Then, re-tighten
The cleaner jig tailings return by gravity to join the rod mill discharge and are returned to the rougher jig. The final jig concentrate is, on an average, made up of 77% scheelite, 8% ferberite, 4% hematite and 11% silicates and oxides. The specific gravity is 5.73. The mesh analysis of the final jig .

Jig. The jig consists essentially of a circular sieve, suspended from one end of a lever, being moved up and down by a cam striking the opposite end of the lever. The concentrates pass through the sieve to the bottom of the tub; the tails pass out by means of an annular opening around the jig shaft. The general arrangement is shown in Fig. 1.
jigs and fixtures are the devices which help in increasing the rate of identical parts and reducing the human efforts required for producing these parts, It has already been emphasized earlier that a centre lathe is a suitable machine tool for producing individual parts of different shapes and sizes, but for producing similar articles in great number its use will not be economical.

The first step of the process is the mixing of powdered bentonite and liquid sulphur (the latter at a temperature of between 125 °C –140 °C). In order to avoid having to remelt solid sulphur, the ideal solution is to transfer sulphur in its liquid form (i.e. as it comes from the
Aug 20, 2013· INTRODUCTION OF BENTONITE: Bentonite is a kind of clay, often containing a small amount of illite, kaolinite, chlorite, Elo stone, quartz, feldspar, zeolite and calcite, which hardness is 1 ~ 2 and density is of 2 ~ 3g/cm3. According to the kinds of exchangeable cation, content and layer charge, bentonite can be divided into Na.

The current manufacturing process for tailor-made bicycle frames is problematic because the use of the current welding-jig increases excessively the workload on the engineer and technicians. Therefore, Mr. Nicolai planned to design and manufacture in-house a new welding jig for tailor-made bicycle frames.
bentonite from coalescing or flocculating with itself. In order for bentonite to be effective in binding with proteins, the bentonite platelets must be separated into a homogeneous suspension. This is the primary purpose of 'aging' bentonite prior to use. The bentonite-to-water ration in the slurry is usually 5-6% wt/vol. The total quantity of
