MOBILE CRUSHERS
& RECYCLERS
Benefits Of Mobile Crusher & Recycler
1. Demolished wasted material (concrete, asphalt, brick, etc.) can be re-used effectively.
2. As the wasted material can be utilized again, the cost for purchasing new material can be saved.
3. The cost for hauling and dumping (of the wasted material) with trucks can be minimized.
4. Even when the processed material should be used outside, the transportation cost can be much saved.
(because of the compactness of the material)
5. The elimination of the trucking also offers less generation of the exhaust gas.
6. The machine can be used whenever and wherever you like because of its mobility.

MOBILE CRUSHERS
& RECYCLERS
Jaw crusher, with superior crushing force and reliability, is installed.
(BR100JG, BR380JG, BR580JG)
• Natural rock, concrete, asphalt concrete, etc., can be crushed with strong force.
Easy transportation and superb maneuverability
• Compact crawler undercarriage is adopted, facilitating job site access/exit.
Semi-Automatic Material Feeding Control is installed
• The Komatsu original controller optimizes material feeding amount to the crusher.
• Plate feeder with speed controller keeps the operation of crusher uniform and stabilized. Thus, unmanned operation is possible.
(BR100JG, BR380JG, BR580JG)
Simple control and easy operation
• Raising/lowering of belt conveyor and removal of foreign materials are easy.
Crushing work is facilitated by preventive functions of macadam accumulation and debris clogging.
(BR100JG, BR380JG, BR580JG)
Options for more effective system
• Ample powered hydraulic-driven optional equipment is available, such as a magnetic separator (chassis mounted), vibratory screen and secondary/tertiary belt conveyors etc., to provide an effective system.
Low-noise and low vibration design
• Low-noise type engine; sound absorbing material; low-speed high-torque type hydraulic pump;
soundproof muffler, etc., are adopted. Thus, overall noise level is low.
Highly reliable hydraulic drive system
• Crusher, feeder and belt conveyor are driven respectively by independent hydraulic pumps, assuring high reliability and easy maintenance.

MOBILE CRUSHERS
& RECYCLERS Komatsu mobile crushers are classified into 3 types.
The jaw crusher can crush large blocks and is suitable for crushing concrete debris and natural stone. It has a swing jaw plate and fixed jaw plate. Those jaw plates crunch material.
The impact crusher is used for secondary crushing and granulation of asphalt, concrete debris, and natural stone. It produces round grains in many cases and is suitable for production of relatively fine grains. The blocks put in the impact crusher are thrown in the tangential direction by the blow bar of the rotor which is rotating at high speed and are crushed by collision with the impact plate. They are also crushed by collision with each other.
The shear shreds industrial waste as well as bulky domestic refuse to reduce its volume, thereby contributing to extending the service life of disposal sites.

MOBILE CRUSHERS
& RECYCLERS Calculation of the production capacity of a mobile crusher varies largely with the type of the crusher, properties of supplied material and rocks, quantity of muck in the material, clearance of discharge setting, rotation speed of the crusher, and size of the products required by the customer, etc.
The following are the basic elements for calculation of production capacity of each crusher.
Relationship between elements for calculation of production capacity of jaw crusher
* When recommending production capacity, confirm the properties of the rock samples from the customer's quarry by crushing them actually.
Production capacity Large > Small Remarks
Clearance of discharge setting Wide Narrow
Hardness of material Soft Hard Hard material may crush easily Ratio of muck in material (in crusher) Low High
Wetness of material Dry Wet
Impurities in material Less Many
Supply rate in crusher – High Efficiency becomes highest when supply rate is 60 – 70% of volume of crusher.
Size of material Small Large
Productivity
