Cone crusher installation and troubleshooting

Installation and commissioning
1.1 machine installed after delivery by the manufacturer, the user should be checked after receipt of the machine and the elimination of transportation for a variety of

problems, and then install it.
1.2 when installing the rack bottom plane of the longitudinal level of tolerance for the 0.5mm / m, horizontal level degrees (measured on the spindle) tolerance of 0.15 mm / m.
1.3 parts upper rack of the rack leveling alignment and tighten the bolt back too for assembly.
1.4 Before starting the machine must be fully checked. Fixed fastening parts, as well as various parts of the lubrication degree V-belt tension, etc. should be checked whether

proper focus.
1.5 examination shall be cut off the circuit switch, and the switch to hang an obvious sign. Marked "not closing" and so forth.
1.6 crusher must load start, no-load commissioning of not less than two hours, turn the trial should observe crusher manufacturer working conditions, such as an abnormal phenomenon

discovered immediately stop and identify its causes; until after elimination the machine can be restarted.
1.7 Application ore feeder evenly fed into the crusher crushing chamber. Start load test should give a small amount of ore, gradual transition to half load, full load. If you

give into the crusher ore ore block is too large or too much, or frequently fall into non-broken (slug) will speed up the machine

The wear and damage. Hence, the control bulk ores and non-broken inside the casing and maintain uniformity to mine the normal operation of the crusher has an important

significance.
1.8 crusher work to maintain the stability of the bearing temperature must not exceed 75 ℃, such as more than should be immediately stopped to troubleshooting.
1.9 crusher parking, you should first cut off the feeder feeding. Subject ore crushing chamber is completely broken, and then cut off the main power to the motor stops.
1.10 Centralized lubrication oil supply system (some models). Consists of a manual dry petrol stations, two to the oil and lubrication piping components. Calcium-based grease

lubricant recommended (GB491-65). Such as the use of sodium based grease (GB492-77), the attention to moisture. Users also have according to their

Conditions of use on behalf of body oil. To the oil, pay attention to toggle plate support surface oil. Users can also be used to bearing oil gun oil filling hole directly. Not

too much, in order to avoid waste. Users can adjust itself to the oil lubrication system, in order to achieve a reasonable oiling purposes.
1.11 crusher discharge opening can be adjusted according to the instructions provided, the user may need granularity and work wear of the tooth plate, at any time after changing

the number of spacers inside the bracket in order to adjust the port of discharge with satisfactory granularity purposes.
1.12 jaw crushing plant optimized in order to do Pai mine mouth easy to adjust, simple, safe and reliable, from the top of the machine and the machine component hydraulic adjustment

device manual pump. After adjusting the port of discharge, simply open the sealing cap on the rear seat, the manual pump connector and from the top machine on,

Start pump to insert or remove shims to adjust the port of discharge to the desired opening, after adjustment shims aid only when the parallel bars of equal length into two tabs

two openings that can be. (Note that the above operations shall be released under the premise of the locking spring

Proceed. ) Another method of direct rotary screw adjustment.
1.13 To make personal safety equipment and accident, the user should develop the necessary safety procedures.
1.14 machine with electronic control devices, see the operation manual electrical control principle

First, the rational use of equipment
1, in order to ensure the product size, must be based on the degree of wear plate umbrella, adjusting row mine clearance.
2, due to the existence umbrella plate surface processing errors and often mixed with iron ore and other foreign matter, in order to ensure safe operation and avoid movable

plates collide with stationary umbrella, Ф1200 crusher discharge opening gap of not less than 25 mm, Ф1650 broken machine not less than 5mm.
3, the device is overloaded, for example: feed particle size is too large, too small or port of discharge any expansion of the feed vent.
4, the maximum size for the ore to the mine mouth should be 80-85%.
5, the action of the spring is when the non-broken materials (iron, metal, etc.) into the crushing space to protect the crusher purposes.
Second, the preparation and examination before operation
1, lubrication part
(1) Check the fuel tank has enough oil, oil meets the requirements, filtering equipment is clean.
(2) test drive pump, check the pump and piping oil leakage and failure.
(3) whether the 0.5-1.2kg/cm2 between hydraulic.
(4) check whether the situation back to the oil flow, oil flow is stable.
2, the body part
(1) based on whether there is loosening the screws.
(2) Adjust the wedge ring and pin piles whether there is loosening.
(3) on the wheel screws are loose, apron damage.
(4) umbrella plate is loose or badly worn.
(5) whether the crusher cavity sandwiched ores or other foreign matter, if any, must be removed in order to drive.
3, the spring portion
(A) whether the spring break, spring screws are broken or badly worn.
(2) the amount of compression spring is in compliance with regulations.
(3) The amount of compression spring in each group are the same.
4, electrical parts
(1) Check the motor graphite brushes in contact situations.
(2) Check the ammeter pointer is in the zero position.
Three methods of operation
(A) driving method
1, check the contents before operation must be itemized checks.
2, starting Dust Blower or dust facilities, starting belt.
3, first press the pump button to start the pump and after the re-start when the oil return normal cone crusher.
4, press the start button to start the crusher, while paying attention to the situation of the swing meter pointer, and not to exceed the rated current of 1.2 times, and pay

attention to the motor and the crusher sound, if an exception should be immediately stopped and checked.
5, the device start operating normally 3-5 minutes after that, you can start a small amount to the mine, and gradually achieve full load.
6, by the fall of the ore hopper mine ore on the disc must remain uniform.
(Two) stop operation method
1, the device stop, must first stop to the mining, ore processing to be completed crusher cavity before parking.
2, press the stop button to stop.
3, press the stop button pump, oil pump stops.
4, stop dust blower or dust removal equipment.
(Three) operation monitoring
1, the operation must be observed voltage, current, oil pressure situation is normal, and timely and accurate records.
2, the device sound is normal functioning ministries, bevel gears should have a strong voice and periodic noise.
3, pay attention to check bearings, motors and other temperature is normal.
Fourth, emergency stop and handling
(A) The following conditions should be found in the emergency stop
1, the motor overload current exceeds the rating, but the machine simply by crushing things.
2, the motor smoke, sparks.
3, the oil temperature abrupt rise back to the oil exceed 60 ℃, oil pressure is not high.
4, non-broken stuck, spring break.
5, the machine another (such as broken walls, rolling acetabular wall, sub-ore disc) rupture.
(Two) high oil temperature, should be idle for some time, increasing fuel, and then stop treatment.
(Three) stop treatment methods handled by parking.
1, dust control system does not work shall not be running.
2, the winter parking two hours or more, must be prevented from freezing oil tank and prevent measures are as follows:
(1) Regular idling, idling every hour 10 minutes.
(2) start the electric heating device to maintain the oil temperature at about 25 ℃.
3, is strictly prohibited due to low oil pressure while removing electrical interlocks.
4, winter needs the oil is heated to above 20 ℃ before driving.
5, rock breaking machine with a load due to power failure or malfunction of a sudden stop when the clip should be cleared ore crushing cavity, so that normal
