High Yield Screening
Crushing Rate Low, Grain Size Fine
Relative roller differential speed operation with mutual scraping action, because of its higher running speed, and also has role of "former pulling back pressure, former blowing back inhaling", the crusher has no requirement of moisture and mud content in any time, will not affect the crushing effect. Material is always all into the whole out to ensure overfill force. Crushing rate low, grain size fine: adopting combined crushing but not impact and strike breaking, it will not produce secondary crushing phenomenon, so crushing rate very low. Two teeth roller center distance will not change once fixed, the materials will be hard crushed instantly, almost no repeat broken, to ensure uniform granule.
Low Investment Costs
Simple Structure With Less Maintenance
Screen and crush together, a small investment: two teeth roller relative rotation form rotary space lattice sieve. To achieve the double effect of crushing and screening, one machine can complete the crushing and screening work. So, you don’t need to match the screening equipment, simplifying system, reduce investment cost. Handwheel or hydraulic structure can adjust the discharging granularity quickly.The equipment adopt modular architecture, can be divided remote installation according to the site requirement, or customer can choose assembly installation, so as to lift and maintain conveniently. Standard modular composite teeth plate more interchangeability and versatility, greatly reduce the replacement cycle of the teeth plate and operating costs.
Environmental Protection & Energy Saving
Integrated Liquid Spring Balance Flashback Protection
Input size≤350mm, the outlet between 3-50 mm can be freely adjusted, a crushing ratio can reach 50.GF crusher machine energy consumption has a function of reserve and kinetic energy release.Less than 0.03mm amplitude and below 70 decibels noise, the micro positive pressure and all enclosed structure forms, completely eliminate the work-site "three evils" phenomenon, prevent workers silicosis, it is truly environmentally friendly products. My company develops automatic concession crusher patented product for the current condition that the coal source is not fixed and more debris . When the wood and other non-magnetic alloy or rubber and other flexible objects can not be broken in the crusher, the two roller quickly and automatically retreat parallel to the above materials, and then quickly returned to the original gap position, to keep continuous operation.
Safe & Intelligent Reliability
Uniform Feeding & Long Service Life
GF4PG teeth roller crusher is security smart and reliable: the machine adopts the double protection of the electrical and mechanical, cabinet is equipped with PLC programmable controller, which has the interlock protection function, can achieve local control and centralized control room manual / automatic control. It is a ideal crusher for the heating and powering. Vibration feeding, uniform distribution: choosing our company's new type anti-adhesion and anti-blocking vibration uniform feeder, reduce the tooth plate eccentric wear, prolong the life of the tooth plate

Teeth roller coal crusher principle is: the fuel enter from up, and discharge directly from bottom outlet, without secondary crushing. To achieve the crushing purpose through crushing and screening by snap action between teeth, the grain evenly, over powder rate is very low, and its broken particle size can be quickly adjusted by the screw, to fully meet the requirements of coal-fired fluidized bed boiler, to avoid fly ash waste. 100% size guaranteed! Hammer crusher, due to repeatedly hammering the fuel, the over crushed situation is more serious, finest material without adequate fuel will fly out, resulting in a tremendous resources waste. If calculate according to waste two thousandths per day, 700 tons of fuel was wasted a year, the direct economic loss will up to $ 800,000.

GF new teeth roller crushers is differential operation between two rollers, it can clean up material between two rollers, so as to prevent clogging phenomenon,100% non-stick non blocked! Hammer crusher has mandatory requirements for fuel moisture, if the moisture more than 6%, the teeth plate will be clog, then the capacity will be lower, if the moisture reached about 10%, the production capacity will be reduced to 1/3 of the rated capacity.

Teeth roller crusher is a slight negative pressure operation mode, no noise, no dust spills, 100% environmental health. Hammer crusher’s working principle, resulting in a positive pressure airflow, severe dust pollution; its mechanical vibration can cause serious noise pollution; direct harm to staff’s physical and mental health.


The performance analysis and comparison between teeth roller crusher and hammer crusher(250t/h coal crushing as a case)

Performance GF teeth roller crusher Hammer crusher Comparative analysis
Operational capability Discharging size Screw control can be adjusted Need to replace the plate, mesh size is restricted Roller convenient adjustment, fully meet the needs of granularity
Over crushed Instant stealth broken, almost no re-break Process of crushing, repeated hammering Hammer crusher over crushed serious, low thermal efficiency of the boiler
Sticky & blocking phenomenon Relative scraping, no blocked and stick Sticky, blocking serious (water content> 6%) Hammer crusher easy to clogging, need to clean manually
Rated output Full rated output (any water content) 60% of the rated output (wet and dry when unevenness) Hammer crusher output only 35% when the water ≥10%, low efficiency
Material Requirements Suitable hardness Low, medium and high brittle materials Middle and high brittle materials Low brittle materials is also effective
Feed size ≤350mm ≤160mm A wide size range
Moisture Water content without any requirements Request moisture content ≤6% If excessive water, the hammer crusher easy to clogging, does not work
Facilities Vibrating screen No need Minimum model 1530 vibrating screen (about 13000dollars) An additional layer to place vibrating screen in hammer crusher building
Heating equipment No need It’s need heating equipment when moisture is 6% or higher Material not drying, hammer crusher can not working
Environmental pollution Noise (no-load operation) Less than 70 db More than 100 db Hammer crusher with big noise, serious noise pollution


Roll balanced rotation, small stream, almost no dust Hammer operation, to generate strong positive airflow, large dust Teeth roller crusher environmental protection, no dust
Vibration Relatively balanced operation, micro-vibration Hammer eccentric high-speed operation, big vibration Hammer coal crusher has high requirements for infrastructure
Coking Material size in line with the requirements of the boiler operation, it does not occur due to the deposition of coke Hammer Crusher is a flexible connection, for coal 5-20mm small stones can not be broken, small stones into the cold slag deposition on the bottom, so that the local flow of quality deterioration, severe coking Coke can cause maintenance and safety hazards
Maintenance cycle Wearing parts replacement cycle (eight-hour day) Teeth plate ≥6 months Hammer, back plate, grate 2-4 months Teeth Roller Crushers long maintenance intervals and reduced maintenance frequency, high efficiency
Equipment energy consumption Equipment weight 28.1t 15t Hammer crusher manufacture simple, low cost, teeth roller crusher manufacture cost is relatively high
Motor power(250t/h) Four roller type total power is 180kw (260+320)KW(Coarse broken+ fine broken) Hammer crusher will take more 400kw power consumption per hour, according to work 10 hours a day, 300 days working plant electricity costs 0.4 yuan / kWh per annum, the annual power consumption more than 1.2 million kw, that is 480,000 yuan

In conclusion:
1. Teeth roller Crusher can save electricity 480,000 yuan than the hammer crusher each year(In Case of 250TlH crusher).
2. Hammer crusher needs to increase: dust collector, vibrating screen, heater, broken building civil engineering and other costs bigger than RMB 300,000.
3. Hammer crusher presence of noise, dust, coke and other environmental problems, which bring inconvenience for normal operation, bring hidden dangers for the health of employees.
4. Because the hammer crusher structure principle cause the material too easy to smash, bringing uncertainty to the circulating fluidized bed boiler for its normal working.

Working Principle

GF4PG four teeth roller crusher is composed by teeth roller with high speed and strength to do the opposite running. The material free fall as meet the gap of teeth roller, the material bigger than two teeth roller gap will be instantly broken and free fall, to achieve the crushing purpose, meet the size requirements. Relative roller with differential operation can cleaning each slot of the material, so as to prevent sticking, blocking phenomenon and make the material without staying on the surface to avoid a repeat broken, avoid over – crushed.
