The working principle of the gangue to roll crusher in Australia

Gangue on the roll crusher on the roll crusher, a mining machinery, also known as double-roll crusher. Mainly used for crushing ore. The machine has the advantages of small size, large crushing ratio (5-8), low noise, simple structure and convenient maintenance. It is characterized by uniform grain size, low crushing rate, convenient maintenance, overload protection sensitivity and safety and reliability. Applicable to coal, metallurgy, mining, chemical, building materials and other industries more suitable for large coal or coal preparation plant coal (including waste rock) broken. Gear crusher crushing capacity, motor and reducer with a distance between the type of hydraulic coupling to prevent power overload, overload sensor protection, safe and reliable. The hydraulic pressure adjustment of the gear gap, the concentrated lubrication of the gear roller bearing. Tooth optimization design, selection of shear shear force, high efficiency and low consumption, uniform particles

Working Principle of Gangue to Roll Crusher

1, The series of gangue to roll crusher mainly consists of roller, roller bearing, compression and regulating device and drive device and other components.

2, the adjustment of the material size: between the two rollers with wedge or gasket adjustment device, the top of the wedge-shaped device with adjustment bolt, when the adjustment bolt up the wedge up, the wedge will move the top roller away from the Fixed wheel, that is, the gap between the two rollers larger, larger particle size, when the wedge down, the activities of roller in the role of compression spring wheel gap smaller, smaller grain size. Gasket device is by increasing or decreasing the gasket

Quantity or thickness to adjust the size of the material size, when the increase in gasket when the gap between the two rollers become larger, when reducing the gap between the two roller pads become smaller, smaller grain size.

3, the drive mechanism is composed of two motors, driven through the V-belt to the sheave wheel drag wheel, in accordance with the relative direction of movement rotation. In the crushing of materials, the material from the feed port through the roller, crushed by crushing, crushing the finished product from the bottom of the chassis out.

4, for safety, the transmission part of the actual situation should be installed according to their own security shield.

Coal gangue on the roller crusher each stick is driven by a separate motor. There is also the use of a motor driven by a belt drive fixed bearing rod, fixed bearing roller shaft at the other end of the gear, driven by the gear drive stick. As the material properties of the activities of the stick around the move, so the gear tooth height must be increased to prevent tooth from the joint. Therefore, the traditional roller crusher are used long-tooth gear drive, which can change the center of the two rollers in the operation without breaking the tooth characteristics.

The working surface of the roller, depending on the requirements of the use, you can use smooth or tooth surface or slot-type surface. If the broken more rigid, abrasive materials, the choice of smooth roller. Because the smooth roller crushing effect on the material mainly crushing both grinding role, mainly suitable for medium hard materials, crushing.

Roller crusher in order to get different size products, the discharge port size must be adjustable. In order to prevent the crusher over-iron damage, it must be equipped with a safety device, roller crusher on the activities of roller-type spring pressure support, under normal working conditions, the spring force is enough to overcome the broken material to crushing force. Between the frame and the movable bearing, the spacer is arranged with different thickness and the number of the spacers can be changed to adjust the width of the discharge port between the two rollers to meet the requirements of different product particle sizes. When the broken material enters the crushing chamber, the spring is compressed , Activity roller retreat discharge mouth increases, the material is discharged, the spring pressure, the active roller reset. This is the mechanical discharge port adjustment and overload protection device (insurance device).
