The Crushers
U-Crush-it’s Amazing Green Crushing machines are British designed and British built mini rubble, stone and concrete crushers made by Red Rhino Crushers. We currently hire out their 4000 series mini crusher which will handle anything from marble and glass through to stone and concrete. They are exceptionally quiet and extremely compact and highly manoeuvrable fitting through a standard doorway.
The mini crushers jaw aperture is 400mm x 170mm and hydraulically adjustable, producing aggregate from 5mm to 70mm in size. The mini crusher accepts a full kerbstone and a 6in(150mm) concrete block for crushing.
Operation is simple and output of up to 6-7 tonnes per hour can be achieved, though this is dependent on the jaw setting material type loading method and operator familiarity.

Description
Single toggle jaw crusher with jaw aperture of 400mm x 170mm - the only mini crusher to accept a full UK Kerbstone. The 4000 series mini crusher is 775mm wide and can travel through doorways, into rear gardens, and enter sites where access and space is restricted. Hydraulically adjustable jaws allow for the adjustment of output product size, ranging from a choice of 5mm up to 70mm.
Material
The 4000 series mini crusher will crush concrete, kerbstones, marble, paving slabs, bricks, blocks, stone, tiles, porcelain, flint, and gravestones etc...
Output
Output will vary according to jaw setting, loading method, loading equipment, input material and familiarity of the loading operator. Up to 6t per hour has been achieved.
Jaws
Hydraulic adjustment lever allows for the quick release of material and adjustment of product sie. A hydraulic jaw reverse is also provided. A hydraulic pressure relief valve and further safety features are fitted as standard. Jaw plates are made of 14% manganese steel which will 'work-harden'. The jaws are reversible (2 'lives.')
Reinforced concrete & Steel
For steel and reinforced concrete it is recommended that you protect your conveyor belt and crush this material having removed the conveyor belt. Removal of the output conveyor system is quick and easy.
Engine
The mini rubble, stone and concrete crusher's engine is a Perkins 14HP water-cooled diesel with a maximum rpm of 3600. The mini crushers engine is economical using red or white diesel. The fuel tank capacity is 10 litres, with 1 litre of fuel lasting approximately 30 minutes.
Tracks and Controls
The mini crushers tracks are rubber and controlled by hydraulic levers. A fast-track lever is available for straight-line tracking. Controls are simple and clearly labelled. A hydraulic oil cooler is fitted to ensure longer life of hydraulic equipment for hotter climates.
Conveyor and Dust Suppression
Dust suppression is fitted as standard to the mini crusher by means of fine water spray nozzles, utilizing standard domestic hose pressure. The mini crushers output conveyor is simple in design with a moulded belt providing strength and durability. The conveyor system can be removed quickly to allow access for cleaning.
Loading
Maximum productivity is achieved by correct loading of the mini crusher; this is a steady feeding of the jaw aperture, ensuring that the jaw or hopper is not over-loaded. Loaded by hand or with a maximum 1.5t mini excavator using a maximum 10-inch bucket, a steady feed method should be employed, as this will produce optimum tonnage per hour. Overloading or swamping the hopper or jaw will reduce output.
Conveyor Mounted Screener Attachment (optional)
An optional conveyor mounted screener is available for the mini crusher. This is for separation of dust and topsoil from the crushing process. Supplied with a 10mm mesh, the screener can also assist with the creation of decorative aggregates.
Safety & Maintenance
There are two emergency cut-out switches located to the front and rear of the mini crusher. The engine cover is lockable and a battery isolator switch supplied. A central external greasing point is fitted. Following an initial 50 hour service, intervals are every 250 hours. The mini crusher is fitted with an engine immobiliser.
