Product Description

Product Introduction
General Introduction:
ATHM Series High Pressure Roll Mill is our new designed with excellent adaptation, high efficient fine crushing and ultrafine crushing and grinding equipment.  It adopts pre-set crushing pressure and uses hydraulic cylinder which matches with energy accumulator to push the two opposite direction running crusher rolls. This design can keep pressure stable during the whole crushing process, so as to achieve high pressure crush between the two rolls. Widely applied to Construction, mining, metallurgy and other fields in fine crushing, our equipment can produce various specifications fine granule products. Also, our equipment can be available for various metallurgical slag fine grinding, the treating process is simplified and the end slag is finer so as to make the follow-up grinding process more convenient.



Remark: There is a wedge-shaped device or gasket adjustment device between the two rolls and on the top of the wedge-shaped device placed an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will move the movable roll from the fixed roll, so the gap between the two rolls become large, and the discharging granularity will get big. When the wedge goes down, under the effect of pressure spring, the gap between them become small and the discharging granularity will get small. The gasket device adjusts the granularity of discharging material by increasing or decreasing the number or thickness of the gasket. When the gasket number increases, the gap between the two rolls become large and the discharging granularity will get big. When the gasket number decreases, the gap between the two rolls become small and the discharging granularity will get small.

Product Features
(1) Adopt triangle belt driving between motor and reducer. The triangle belt will slip if load is too big, which can protect the motor.
(2) The connection between the swing roller part and reducer adopts universal spindle coupling, which not only make sure the swing roller have enough adjusting range but also protect the motor and reducer in case that damage due to overload.
(3) The roller part is the hardcore part of the crusher. The connection between mill roller and main shaft adopts key and taper sleeve, which is dismounting easily.
(4) The gap between two rollers can be read from staff.  The place where there is a hole under the staff is the zero reference line. The gap is 10 mm when the machine leaves the factory. The client can adjust the roller gap according to requirement. 
(5) The frame and base frame adopt box type structure, which is strong, safety and reliability.
(6) The workers can adjust the speed of two rollers through change the motor triangle belt. The efficiency will be good when the speed of two rollers is not the same, but roll skin wear faster.
 

Product Features

1. Adopting high pressure crushing theories to material so as to achieve higher crushing efficiency, higher crushing ratio and wider adaptation.
2. Automatic adjusting roll surface interval to keep the set crushing force stable, product shape better and granule finer.
3. High wear-resistant alloy and mosaic roll surface liner structure to ensure long lifetime and without dismantling replacement.
4. Equipped with reliable performance hydraulic control system to protect the equipment from iron and overload.
5. The working pressure and rotation speed can be adjusted rapidly according to different working conditions.
6. Constant and nonimpact crushing force to material from the crusher rolls can achieve low noise and less dust.

Working Principle
There is a wedge-shaped device or gasket adjustment device between the two rolls and on the top of the wedge-shaped device placed an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will move the movable roll from the fixed roll, so the gap between the two rolls become large, and the discharging granularity will get big. When the wedge goes down, under the effect of pressure spring, the gap between them become small and the discharging granularity will get small. The gasket device adjusts the granularity of discharging material by increasing or decreasing the number or thickness of the gasket. When the gasket number increases, the gap between the two rolls become large and the discharging granularity will get big. When the gasket number decreases, the gap between the two rolls become small and the discharging granularity will get small.
