Roll crusher is a long macro structural principle in accordance with the crusher designed and developed new products with high-tech content.
Roll Crusher has a small, broken the advantages of easy ratio (5-8), low noise, simple structure, maintenance, and production rate (-2 times higher than the now 2PGC tooth roller crusher production), broken materials uniform particle size, had crushed a low, easy maintenance, sensitive overload protection, safety and reliability.
Roll crusher for coal, metallurgy, mining, chemicals, building materials more suitable for large-scale coal mine or coal preparation plant raw coal (including waste rock) broken. Roll crusher, with limits from the fluid coupling between the motor and reducer connections to prevent power overload, overload sensors, safe and reliable. Roll spacing hydraulic adjustment of the toothed roller bearings centralized lubrication. The optimized tooth design, select the broken pull shear, high efficiency and low consumption, the particles evenly.
Roll Crusher
The birth of the PCM Roll crusher completely replace our existing 2PGC tooth roller crusher.
Roll Crusher Zhengzhou universal mining machinery plant production toothed roll crusher is divided into Double Roll Crusher Four Roll Crusher series, Double Roll Crusher is a mechanical spring-loaded (2PCM), the Roll crusher broken material properties and requirements with crude Roll or tooth roll, four-toothed roll crusher is actually formed by two bidentate roll crusher combination.
Roll Crusher Working Principle and the main structure:
Roll Crusher high-speed rotation of special wear-resistant Roll split broken (the traditional Roll Crusher using low-speed compression and bursting) of the material, the formation mechanism of high productivity.
This tooth roll crusher gear, rack, part of the crushing roller, mechanical spring device, linkage components.
Roll Crusher machine discharge size and selection of Roll structure is related to the selection must be marked with the size of the feed size
Roll crusher in operation need regular maintenance on the roll surface. Smooth roll crusher sometimes equipped with a wheel on the rack, When the roll surface grind the pits or grooves, you can not tear down the roller surface of the roller surface on the machine grinding repair. The tooth surface roll crusher teeth plate or ring gear can be replaced or use a U-turn. When the teeth wear to a certain extent, must be replaced or repaired, otherwise cause broken non-uniform particle size, increasing power consumption, and production dropped. Some surfacing machine is also equipped with a device can be directly on the machine for repair. Accompanied by some smooth roll crusher roller axially reciprocating the mobile device automatically, so that the roll surface wear uniform.
Roll surface wear and tear, the increase in the width of the discharge opening, the need for the activities roll adjustment (single roll crusher to adjust the jaw plate). Adjustment needed to keep the two rollers parallel to each other, to prevent skewing.
Plain bearings, roller crusher should be noted that the gap of the roller bearing. The tip clearance of the roller bearing and the journal is usually 1/10000 of the journal diameter ~ 1.5/10000 bearing side clearance is the tip clearance of 1/2 to 1/3.
In order to ensure the normal work of the crusher, the need to frequently check the lubrication of the bearing. The sliding bearing oil cup is often used to fuel or injection of dilute oil by hand on a regular basis, Rolling regularly oiling for lubrication and sealing.
