NAWACONE 3000 GLH

The Long Head model is built for larger feed and capacity. It is sturdily built to withstand severe crushing loads generated by toughest of the rocks. The main body is made up of top and bottom shells of heavy cast steel sections, precision machined to receive the spider bearing, eccentric and counter-shaft assemblies.

The crushing chamber comprising of non-choking curved mantle and concave of high manganese castings, is designed to nip larger lumps of primary crushed rocks. And higher crushing volumes are achieved with evenly distributed wear.

The forged mainshaft of special steel is precision machined and fitted with a cast steel core on which the mantle is mounted. A positive dust seal arrangement effectively prevents ingress of dust from the crushing area into the eccentric bearing elements and bevel-pinion gear train.

The high precision gyro elements comprising of cast steel eccentric, set of inner and outer journal bearings of special metallurgy are driven through a bevel gear-pinion and counter-shaft assembly running on antifriction bearings. The eccentric and mainshaft are supported at bottom end by hydraulic pressure through a set of thrust plates for taking the vertical loads.

A hydro-lube system incorporates all machine-safe controls. The lube pump circulates and lubricates the gear train, main & counter shaft bearings. The hydraulic circuit ensures smooth CSS adjustment and trouble-free operation of the crusher. The spider bearing in the top shell is grease-lubricated either manually or by an automated grease pump (optional).
