Jaw Crusher

The Jaw Crusher is used in mining, metallurgy, construction, highway, railway, irrigation and chemical industries, and our jaw crushers have the features of high reduction ratio, even powder sizes, low power consumption and easy maintenance. The crushing strength of the jaw crusher materials is up to 350 Mpa.

Feature Of Jaw Crusher:

1) High reliability 2) Flexible capacity 3) Over-loading protection 4) Easy replacement of wear and spare parts 5) Long service time 6) High efficiency

Jaw Crusher Operating principle:

The 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. Working Principle of Jaw Crusher: The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.

The Impact crusher is used in secondary crushing of material,The impact crusher processes various kinds of material with crushing compression strength not more than 350 mpa, featuring firm structure, stable performance, large capacity, even producing granularity ,convenient maintenance and economical running expense, and widely applied in the areas of mining ,construction material,smelting, railway, highway, water conservancy, etc.

Feature Of Impact Crusher:

1) High reliability
2) Easy replacement of wear and spare parts
3) Long service time
4) High efficiency

Working of the Impact Crusher:

When the materials enter the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output.

When some foreign stuff enters the machine, the impact frame will fallback, the stuff falls from the machine. This device can prevent machine from damages.

How Impact Crusher works?

The Impact Crusher is mainly used in secondary crushing; it can crush material whose crushing compression strength is not more than 320mp. It is suitable to produce high rank highway ? hydroelectric and building material.

Illustration of How impact Crusher runs

When the materials enter the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output.

When some foreign stuff enters the machine, the impact frame will fallback, the stuff falls from the machine. This device can prevent machine from damages.

Purpose Of the Impact Crusher

The Impact Crusher Used for mineral dressing, chemical, cement, building, refractory materials, ceramics, glass and other industrial sectors in intermediate crushing and fine crushing of diversified medium hard ore, such as limestone, calcined lime, clinker aggregate, slag, cullet, calcium salt, crude ore, building material, coke, coal, etc.

Operating principle OF the Impact Crusher

The Impact Crusher Machine rotor revolves in fixed direction by means of driving action of triangle belt that connects with motor. Above rotor, there are two sets of suspended impact plate. Material enters into rotor through charging hole and feeding guide plate. The plate hammer fixed on rotor strikes onto impact plate and then fall from it to mutually shock material blocks that are successively delivered upward by rotor. Therefore, material block will be moved recurrently and repeatedly in the crushing chamber that is composed of rotor, impact plate, guide plate and chain curtain, by means of which intense shock phenomenon will come into being, and the material block will be crushed along its natural crack or concave and bulge.

HPC cone crusher machine is suitable for:

SBM HPC series hydraulic cone crusher with high efficiency is suitable for primary crushing of many kinds of mining and rock whose compression strength not higher than 360Mpa, such as ore, concrete, fireproof material, alumyte, quartzite, corundum, perlite, ironstone, basalt etc. SBM HPC series hydraulic cone crusher is widely used in mining and construction, concrete factory, sandstone making industry.

SBM HPC cone crusher machine machine structure:

Cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.

SBM HPC cone crusher machine benefits and features:

1) High crushing ratio with high efficiency.
SBM HPC cone crusher machine introduces “eccentric bushing circum fixed shaft” special working principle, and strengthen the main shaft, which is possible to realize crushing with larger power. Crushing cavity of the HPC cone crusher adopts layer pressure theory and the matching speed will sharply increase the crushing ratio, output, so does the cubic product percentage.
2) Double insurance hydraulic governing system
SBM HPC series hydraulic cone crusher machine equipped with insurance cylinder, lock cylinder, lock oil cylinder. They not only protect the machinery but can deal with troubles without disassembly the machine parts. So the maintenance is easier than spring cone crusher.
3) New gearing adjusting system
SBM HPC series cone crusher adopts newly hydraulic driving system and function of self lock &wide adjustment.
4) Grease seal and effective labyrinth seal
SBM HPC cone crusher is adjusted by hydraulic device and lubricated by the dilute oil, which is helpful to avoid water jam, and radically eliminate the defect of water and oil in the traditional spring cone crusher.
5) Hadfield’s manganese steel is used in mantle and bowl.
Owing to the change of the crushing cavity and the protection of the crushed products, the abrasion decreases, and the service time is 30%-80% longer than traditional cone crusher.

Common problems for HPC cone crusher:

The performance of ordinary hydraulic pressure cone crusher can acts as the reference for the performance of HPC series cone crusher. As a composing unit of the production line, its performance can be influenced by other units like feeder, belt conveyor, vibrating screen, motor, transmission part and hopper, etc.
Take care of the following factors which can influence the performance of hydraulic pressure cone crusher:
1. choose the right crushing cavity according to the materials be crushed;
2. the feeding size should be right;
3. materials distributed equally around the round of crushing cavity;
4. automatically control system;
5. discharge opening of cone crusher works normally;
6. the model of belt conveyor be seasoned with the max. processing ability of the crusher;
7. Choose the right screen model for advance screening and closed screening.
The following character can decrease the capacity of Hydraulic Pressure:
1. the fine particle with size less than that of feeding hole surpass the max. capacity of the crusher by the extent of 10%;
2. Sticky materials mixed in the feeding;
3. No feeding control;
4. Materials allocated improperly around the crushing cavity;
5. The recommended power not used;
6. Screening capacity not enough;
7. Discharge opening now works normally;
8. Materials too hard or too elastic.

Note: SBM HPC cone crusher is a kinds of hydraulic cone crusher,it is can be used to replace ordinary hydraulic pressure cone crusher in the line of mining and construction. It is the most ideal crusher equipment for large stone crushing factory and mining industry. know more crushing machine,click the keywords “cone crusher”. If you want to know more info about mining&grinding ,visit our website: http://www.unishm.com .
