Project Report on Setting Up of Stone Crusher
Stone crusher for crushing various types of stone, depending on the broken principles and products of different particle size, is divided into many models. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and stone industry and many other sectors. Commonly broken machinery jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher, etc..
Jaw Stone Crusher:
Jaw crusher can be different sizes of raw materials, broken into small pieces of uniform particles, jaw crusher either supporting and beneficiation equipment, sand and gravel equipment can also be used alone. Jaw crusher can produce the cornerstone of the road, railway ballast stone and construction sand and gravel aggregate. The Jaw Crusher divided into coarse crushing jaw crusher and crushing jaw crusher, which is commonly referred to as PE series jaw crusher and PEX series jaw crusher. Liming Heavy Industry producted jaw crushers, which have crushing, product uniform particle size, simple structure, reliable work, easy maintenance, low operation cost characteristics.
Jaw Stone Crusher Operating Principle:
This jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
Jaw Stone Crusher Using:
The jaw crusher is often due to improper use caused the crash phenomenon crusher to be crushed when the material, we must pay attention to pay attention to the uniformity of the material under, there is the hardness of the material was suitable, if perfect, can plus one step.
The main factors that generally affect the jaw crusher nip angle and the number of revolutions. Nip angle is moving Hubei and the angle between the fixed jaw. According to the calculation of the maximum nip angle up to 32 degrees. The actual use are less than 25 degrees, typically about 18-20 degrees. Nip angle is too large, make up the ore crushing cavity extrusion, resulting in injuries or damage to other equipment, at the same time as the nip angle increases (broken than increase) decrease in productivity. Adjust the size of the port of discharge, and also change the size of the nip angle. In real life, according to the row of ore particle size to adjust the size of the discharge mouth. Therefore, to ensure that the product size requirements, try to Pai mine mouth amplification is reasonable. Pai mine mouth size can be adjusted by adjusting the block to adjust the size of the port of discharge, pay attention to the broken relationship between the ratio and productivity.
Within a certain range, an increase of the number of revolutions of the eccentric shaft, the production capacity of the crusher can be improved, but also increases the power consumption of the crusher unit weight of ore. The speed is too large, the time to discharge causes the crushing chamber has been crushed ore to produce clogging, but the production capacity to reduce, increase in power consumption, therefore, jaw crusher should be an optimum number of revolutions.
Jaw crusher eccentric shafts, connecting rods, movable jaw plate, shaft and liner wear parts, lubrication and replacement needs constant attention.
Fault Repair:
The jaw stone crusher common faults and exclusion method:
1, The host suddenly shutdown (commonly known as: stuffy car).
Reasons: 1) the discharge opening clogged, causing wholehearted blocking material; 2) V-belt drive sheave rotation too loose, causing the belt slipping; 3) tight set of eccentric shaft sleeve is loose, causing no clearance on both sides of the rack bearing , the eccentric shaft card dead, can not rotate; 4) workplace voltage is too low, the host encounter aniseed, weakness broken; 5) bearing damage.
Remedy: 1) Clear discharge opening obstructions to ensure smooth material; 2) V-belt tightening or replacement; 3) re-install or replace the adapter sleeve; 4) adjusting the voltage of the positive workplace to make it comply with the host operating voltage requirements; 5) replace the bearings.
2, Host sheaves moving jaw functioning normally, but broken cease work.
Reasons: 1) tension spring break; 2) Trolley fracture; 3) bracket off or broken.
Remedy: 1) replace the tension spring; 2) replace the trolley; 3) re-install or replace the bracket.
3, Production to reach factory standards.:
Reasons: 1) the broken material hardness or toughness over the use of the limits prescribed by the manual; 2) motor wiring position is reversed, host open anti-vehicle (moving jaw clockwise rotation), or motor delta connection connected as a star connection; 3) the discharge opening is less than the specified limit; 4) jaw displacement, addendum addendum relative; 5) low voltage work site; 6) movable jaw and bearing wear, the gap is too large, the bearing outer ring occurred relatively rotation.
Remedy: 1) replace or increase crusher; 2) replacement motor wiring; 3) to the instructions provided for nominal discharge opening and increased crusher for crushing the nesting population adjustment; 4) Check the teeth plate pitch dimensions, such as shall be sub-standard replacement jaw, adjusting the relative position of the fixed jaw plate and movable jaw plate the addendum tooth root, fixed clamping to prevent displacement; 5) increase the voltage to meet host weight set out requirements; 6) the replacement of the bearings or moving jaw.
4, Have beat or percussion work activities with fixed jaw plate.
Reasons: 1) jaw fastening bolts loose or falling; 2) the discharge opening is too small, the bottom of the mutual impact of the two jaws.
Remedy: 1) tight set or filled and bolts; 2) is adjusted discharge opening, ensure the correct gap of two jaw.
