Sandvik UD440E is a self-propelled tracked primary and secondary crushing and screening unit in one. It is aimed at the demanding quarry operator, construction company or contractor in need of high productivity. Fitted with Sandvik CJ412 jaw crusher, Sandvik CH440 cone crusher and Sandvik SS1443 triple deck product screen, it can produce up to 500 tph. The machine is mostly powered by electricity (tracks and support legs are hydraulically driven), which results in an environmentally friendly and cost effective solution.
The machine can be ideally fed by an excavator or alternatively, by a wheel loader. The fines are initially separated by means of a pre-screen below the grizzly, and then fed into the jaw crusher. The crushed material is then sized by Sandvik SS1443 screener, with the oversize subsequently crushed by Sandvik CH440 cone crusher, which operates in closed circuit with the screen. Sandvik UD440E is a very versatile plant, in that it can also operate without the cone crusher, should the end product specification not need a secondary crushing step.
