We offer Sand Classifiers which are used for the separation of crushed sand (stone particles below 3 mm.) from natural mud or silt, is based on the principle that the former is heavier than water but the latter is not. Silt mixed crushed sand if used for making concrete yields low strength and hence this machine is particularly useful for obtaining crushed sand for use in high strength concrete. Our Sand Classifier consists of an inclined screw conveyor with a water jacket. Water is retained till a particular level. The mixture of silt and sand is fed at the feed (lower) end of the inclined screw conveyor. The silt particles being lighter than water do not settle down and are drained away with water. The crushed sand being heavier than water settles on the bottom part of the trough of the screw conveyor and is conveyed at the discharge end.

Crusher has a multiple-speed impactor which is used in  primary or secondary crushing of concrete and asphalt rubble and limestone. Cedarapids 5048LP impact crusher has a standard 3-bar or optional 4-bar configuration. Hopper capacity is 12 cubic yards. Major features includes  hydrostatic drive, advanced electronic control system, hydraulically assisted apron setting, grizzly feeder with integrated prescreen, selectable discharge to bypass and dust suppression on main. Such plants can be tailor made to suit factors such as application, capacity and site conditions.

We offers Horizontal Shaft Impact (HSI) crushers which are best used for primary or secondary crushing operations. The HSI consists of a horizontal rotating shaft to which a rotor is attached. The shaft is placed inside a chamber which is lined with replaceable blow bars. The material is fed into the top of the chamber where it impacts the rotor and is reduced in size. The rotor then throws the material outward against the hard wearing liner material. In this manner the material is reduced by repeated impact against the rotor and the blow bars until the desired material size is reached and it drops through a sizing device. Material sizing is achieved by rotor rotational speed and adjustment of the clearance between the blow bars and rotor. The blow bars are reversible to even out wear and are easily replaceable. HSI's offer high throughput primary and secondary crushing with good control of product size. Good choice where high reduction ratios are required. Capital cost per ton of capacity is low, however higher rotation speeds and wear will result in increased operating and maintenance compared to other types of primary crushers. HSI's work well with ore that is sticky or have high clay content.
