High efficiency energy saving roller grinding (pressure) machine
First, product overview
High efficiency and energy saving and grinding (pressure) machine is my company in the market all roller press advantages, its own research and development of the most reliable grinding equipment, applicable to compressive strength is less than 300mpa, humidity less than 30% of the hard material crushing operation can be widely used in cement, mining, metallurgy, ceramics, mining, metallurgy, building, highway, railway, water conservancy and chemical industry and so on many industries. With a large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance, operating expenses, and other characteristics of the economy.
Energy-saving roller mill (pressure) machine is equipped with two solid roller, roller surface by build-up welding roller surface and a hard alloy column nail roller surface, applicable to feed size less than 40mm, the particle size of finished products demand of fine working below the 4-15mm. Such as cement industry, the mill before the pre crushing cement clinker, limestone and composite materials; iron ore industry into grinding pre broken slag, iron ore, silica minerals; unburned brick factory and crushing various ores do unburned brick, or with the similar occasions.
Two, working principle
High efficiency and energy saving roller grinding (pressure) machine is two opposite rotation on the solid roller and relatively high speed rotating, the principle of inertial dynamics generated high extrusion pressure (pressure is generally set to 150MPa), material by distributing device into two roll gap (V type of crushing chamber), extruded, shearing makes material mechanism changed, the complete destruction of the material of the internal crystal structure, so as to achieve the material cakes and powder, finally from two roll gap in the fall, the discharge port of discharge.
Three, equipment characteristics
1, the structure is compact, the design is strong, the material mouth is big. The whole crusher can be divided into two parts, the upper and the lower frame body. Two arm frame is composed of alloy steel, special alloy steel for protection, a rolling mortar wall mounted on the shelf body. A heavy oil cylinder at the lower part of the lower frame is used to support the main shaft and adjust the position of the main shaft so as to control the size of the discharge port.
2, the hydraulic adjustment system has better overload protection function. The spindle is supported by the lower cylinder so spindle and dynamic cone lining board to rise and fall together, when after the miscellaneous iron and other not broken objects into the crushing chamber, big crushing force in moving cone, dynamic cone decreased rapidly, impurity of iron and other not broken objects as soon as possible through the crushing chamber, realize the crushing machine overload protection function.
3, CLP constant crushing cavity design. CLP means that the performance of the lining board is kept constant. The crushing and feeding mouth area is almost vertical, and the shape of the crushing cavity is almost unchanged during the whole process of the lining. Therefore, the crusher's production capacity will not be because of the lining board wear and smaller, can effectively reduce the operating cost.
4, it is easy to operate and maintain. All the operation and maintenance of the hydraulic cone crusher can be completed from the upper part of the crusher, which makes the operation of the crusher more easily, and the maintenance cost is lower.
Four, technical parameters
remarks
1, marking the way (in 2PGJ0612 as an example): 2, said the two roller, P said the crusher, G said the roller, 06, said the roller diameter (600mm), 12, said the roller width (1200mm).
2, the above table out of the particle size of the particle size can be adjusted.
3, due to continuous technical improvements, the above data is for reference only, the actual data to CAD electronic version of the drawings.
