Product Description
China Henan province Zhengzhou city Changxing Machinery Equipment Co., LTD., Specializing in the production of: roll crusher is divided into two structures of double roller crusher and four roller crusher crushing equipment.
Roll crusher for roll crusher is mainly composed of the roller, the roller bearing and compaction and adjusting device and device drivers, toothed roll crusher is mainly the use of special wear-resistant high speed rotation teeth roll to split and broken material, form the mechanism of high productivity, the maintenance of the machine is an extremely important regular work, it should be in close coordination with the extremely operation and maintenance, etc.
Roll crusher Roll crusher (for Roll crusher | for Roll crusher | double Roll crusher) applies in cement, chemical, electric power, metallurgy, building materials, refractory industries crushing medium hardness materials, such as limestone, slag, coke, coal, such as Roll crusher
The crusher, finely homework.
This series of roll crusher is mainly composed of the roller, the roller support bearings, pressure and adjusting device and driving unit and other parts.
The working principle of
1, this series of roll crusher is mainly composed of the roller, the roller support bearings, pressure and adjusting device and driving unit and other parts.
2. The adjustment of the discharging granularity: with a wedge or gasket between the two roller adjusting device, adjusting bolt, wedge at the top of the device when the adjusting bolt will wedge pulled up, wedge rolling activity to the top from the fixed wheel, namely two roller clearance greatens, discharging granularity, when the wedge downward, activities under the action of the roller in a compression spring two rounds of smaller clearance, discharge size smaller. Gasket device is through the increase or decrease in the number of gasket to regulate the partical size or thickness, when add gasket two roll gap get bigger, when reduce the gasket two roll gap become smaller, the partical size.
3. The drive mechanism is made up of two motors, through v-belt transmission to the Geneva wheel to drive the roller, according to the relative rotation direction. The broken material, material from the feed port, through the roller, the rolling and broken, broken after the finished product out from beneath the chassis.
4, for the sake of safety, transmission parts should be according to the actual situation to install safety cover.

The machine maintenance
1, all the load bearing of crusher bearing for machine, so good lubrication for the bearing life has a lot to do, it directly affects the service life of machine and availability, and requirements into lubricating oil must be clean and seal must be good, the machine's main oil (1) the rotation bearing (2) roll bearing (3) all the gear bearing, sliding plane (4) activities.
2, the tire of the newly installed prone to loosening should be check regularly.
3, pay attention to each part of the machine working normally.
4, pay attention to check the easy wear parts wear degree, attention to replace the worn parts at any time.
5, put activity unit chassis plane, should be out dirt and other material to avoid activities when machine can't broken material bearing can't move on the chassis, so that a serious accident.
6, bearing high oil temperature rise, should immediately stop to check the reason.
7, the rotation gear in sound operation, if there is impact should immediately stop check, and remove.
Installation commissioning
1, on the basis of the device should be installed in a horizontal concrete, land bolt is fixed.
2, when installation should pay attention to the main body of vertical and level.
3, check each part after installation bolt fastening, the presence of loosening and host storehouse door whether such as welcome to tighten.
4, according to the equipment power configuration of power and control switch.
5, check finished, empty load test, the test can be normal production.
Basic operation
1, in order to ensure the maximum output of a roller crusher, feeding must be continuous uniform distribution on the length of the roller,
2, should be check regularly whether the discharging mouth jam phenomenon, and the motor stop working to stop feeding before, when the material block down completely, the roll into idle, before power motivation.
3, if the direction along the length of the roll feeding non-uniformity, roller surface not only wear faster, and the uneven wear of every point, there will be a circular groove, the normal crushing work is damaged, broken product particle size is not uniform. Therefore, except for coarse crushing roller crusher, finely roll crusher usually include a feeding machine, to ensure the continuous, uniform feeding, and equal to the length and the length of the roll feeder, the feeding direction uniform along the length of the roll.
4, the roll crusher reasonable maintenance and correct operation, to ensure long-term continuous working, reduce the stop time, only the normal management and monitor the normal work of the roll crusher, every day to prevent failure, to ensure its continuous work. Therefore, the operator should pay attention to the following items:
(1) pay attention to the bolt fastening components, such as found loose should immediately tightened;
(2) before work you must first start the roll crusher, after being normal speed, then machine feeding, when parking program instead;
(3) regular inspection discharging mouth, if found to have jams, should be clear;
(4) pay attention to check parts wear degree, watch to replace worn or damaged parts;
(5) should not overload the machine, should watch for electrical instrument;
(6) bearing oiling shall promptly, and not make the bearings with oil;
(7) should be controlled bearing temperature, the temperature rise shall not be higher than the surrounding air 25 ~ 30 ℃;
Active device (8) chassis plane, should remove dirt and other material, in order to avoid the roll crusher can't broken materials, activities bearing can't move on the chassis, and serious accidents.
