Product Introduction

HLPME series roll crusher has the advantages of great capacity of crushing, small unit energy consumption and wide application. Mainly used in electric station, mining, coal chemical industry and other industries. It is one of the best choices for breaking coals for crushing coal for circulating fluidized bed boiler in power plant, pulverized coal furnace, coking plant, iron-works, etc.

Operating Principle

Two motors drive rollers of the first and second level in the opposite direction. When materials comes into the first crushing level from the distributor. interlaced teeth crush the materials from 300mm to 50mm and below. Then, materials come into the second crushing level for further crushing from 50mm to 10mm and below. Rollers teeth are crossed with each other which can crush materials with effects such as cutting, splitting, breaking, pulling, etc. Meanwhile, materials rolled over and over during crushing so that the crusher can find the most fragile position for crushing. Toothed rolls only crush materials of bigger size, small size materials that meet the requirement can discharge direct to avoid over-crushing.

Main Features

       1. Single crusher still has high output and the size is even. The size can be arbitrary adjustable in the range of 10 to 15mm.
       2. Air eddy offsets each other, meanwhile, the leeway of the feeding and discharging hoppers is approximately equal, which leads to no dust rising. There’s no need for installing special dust removal equipment.
       3. The adopting of a special kinematic principle makes the crusher no sticks and stop-up and no particular moisture requirement of the materials.
       4. The toothed plate is forked tail type which adopts sliding lockers to fasten the plate and achieves easy removal of it.
       5. The design takes fully advantages of pull crushing theory and kinetic energy principle to reduce idle work. Thus, its energy assumption is 50%-70% of same type’s ring hammer crusher.
       6. Change lubricating oil automatically to protect the bearing and prolong its usage life. 
       7. Humanization design, easy to change wear parts, can achieve automatic and intelligent control.
