· We have developed a centrifugal gel-crushing method using a pipet tip. Polyacrylamide gel slices are extruded from the narrowing cavity of a pipet tip by centrifugation in a few minutes to crush them into pieces of appropriate size. The size of the crushed gel could be controlled by several parameters, including centrifugal force

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of

· 1.1 Principle. Crushing is used to very quickly produce a fine powder from a bulk material or fine particle using mechanical crushing. This technique is essentially used to investigate ceramics, minerals, and mixed–composite materials. Materials must be brittle or made brittle and of a high hardness to average hardness.

· It is to be noted that a surprising uniformity of wear was obtained. As nearly as can be ascertained, the average capacity increased from 90 to 104½ tons per hr, or 16 pct, and the total average tons crushed per set of liners increased from 71,000 to 84,000 tons, or 18 pct, in spite of the fact that the liners were 15.6 pct lighter.

Liner wear in crushing cavities of secondary and tertiary crushers can become an appreciable cost item when the material to be crushed is hard and abrasive. This item of cost not only includes the value of the crushing members, but also more intangible costs such as labor and lost production due to more frequent replacement.
