Fine jaw crusher working principle
Fine jaw crusher eccentric shaft is divided into two parts, the same eccentric shaft, eccentric in the opposite direction, each part of a moving jaw hanging head, motor through the belt-wheel drive the eccentric shaft by the groove, when the eccentric shaft rotates, the movable jaw the first track by eccentric reciprocating motion, while moving jaw broken material to fixed plate movement, the other side of the movable jaw away from the fixed plate nesting, alternating movement to complete the process.
Fine jaw crusher Introduction
Fine jaw crusher crushing chamber is relatively small jaw crusher, broken out of the product particles is generally uniform.
Characteristics of Fine jaw crusher
1. Crushing chamber depth and no dead zone, increased feed capacity and output;
2. The crushing ratio, even granularity;
3.Gasketed nesting population adjustment device, reliable and convenient, adjustable range, increasing the flexibility of the equipment;
4. Lubrication system safe, reliable, easy to replace parts, maintenance workload is small;
5 simple, reliable, low operating costs.
6. energy-saving equipment: stand-alone energy-saving 15% to 30%, more than double the energy system;
Use of Fine jaw crusher
Fine jaw crusher has been widely used in mining, metallurgy, chemicals, building materials, road, rail, water and other industries. Fine jaw crusher for the broken, the compressive strength limit of less than 2000 kg / cm 2 of various minerals and rocks.
structure of the fine jaw crusherFine jaw crusher main frame, moving the jaw, eccentric shaft, jaw plates, brackets and other component parts, electric motor through V-belt turning the eccentric shaft, so that moving the jaw has been adjusted according to the track for exercise, and to the crushing cavity material broken.A single rack system steel pouring a whole, the anterior wall coat rack useful for wedge bolt fixed jaw plate, around the rack in the crushing chamber side wall is equipped with a shield to prevent the rack sidewall wear.
Installation and maintenance of Fine jaw crusher
Machine maintenance is an extremely important regular work, it should be extremely closely with the operations and maintenance, etc., should be full-time staff on duty checks.
I. machine maintenance:
1, all load bearing shoulder of the machine, so good lubrication of the bearing life of a great relationship, it directly affects the life of the machine and the operation rate, which requires injection of the oil must be clean, seal must be good, the machine main oiling Office
(1) Turn the bearing
(2) roller bearings
(3) All gear
(4) activities bearing, sliding plane.
2, the newly installed tires prone to loosening must always be checked.
3 note that the various parts of the machine is working properly.
4, pay attention to check the wear parts and replacement of the worn parts.
5 put the event the device chassis plane, dust and other things so as not to be out of the machine when the material could not have broken the bottom shelf in the activities of the bearing cant move, so as to cause serious accidents.
6, the bearing temperature rise, the reasons should be immediately stopped and checked to be eliminated.
7, turn the gear when in operation should be immediately stopped if the impact of the sound check, and eliminate
II. Installation test:
1, the device should be installed on a level concrete foundation with anchor bolts.
2, the installation should pay attention to the level of the host body and the vertical.
3, various parts of the installation check for loose bolts are tightened and doors of the host, where do the tightening.
4, according to the device's power cord and control switch configuration.
5, the inspection is completed, the empty load test, you can test the normal production.
