Perlite: main uses

Use perlite to aid drainage. Succulents and other plants sensitive to moist soil benefit from having perlite added to the potting compost. The perlite will trap air in the compost and encourage water to drain through, ensuring the plant's roots will never sit in damp soil. Mix perlite with compost at a ratio of around 1:4.

Vermiculite vs. Perlite: What's the Difference?

Professional growers buy perlite wholesale in larger bags, but these can be a bit bulky for the consumer. A bag that is 2 cubic feet weighs about 8 to 16 pounds when dry. The 4 cubic feet size is more manageable in this case than with vermiculite. The difference in weight comes from the fact that perlite is airier than vermiculite.

Experimental Investigation of Novel Enhanced Gravity Closed Spiral

Classifiers have found wide applications in the mineral processing industry. In this study, a novel enhanced gravity closed spiral classifier is presented. This device uses induced centrifugal force to classify particles. A functional prototype of the separator was 3D printed to experimentally validate the concept. The performance characteristics …

Rake Classifier

rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …

An operational model for a spiral classifier

2. Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough ( Burt, 1984 ). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.
