Comparing with other common roller mills, vertical roller mill has the space-saving design, reducing the civil construction costs.

Introduction

One of the most popular stone-crushing equipments in the world, Jaw Crusher is ideally suitable for primary and secondary crushing. The highest anti-pressure strength of crushed material is 320Mpa. Our design and production are of high position both at home and abroad.Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material is 320MPa.

Structure Features

High performance

  1)The hot air will contact with the materials in the grinder, with strong dry ability and energy-saving.

  2)By adjusting the temperature of the hot air, it can meet the requirements of materials with various degrees of moistures.

  3)Short stay in the grinder and convenient to inspect and control the particle size and the chemical components, which have reduced repeating grinding and improved the products’ stability.

  4)The equipement have been installed on the roller and the grinding plate, which can avoid the destructive shock and the shake.

Low investment cost

  1)This series of grinder have intergrated the crushing, dry, powder grinding and the graded transmitting into the single whole, whose cover area is just 80% of the ball mill system.

  2)The roller can directly grind and crush the materials on the grinding plate, whose consumption is just 30%-40% of the ball mill system.

  3)The roller and the plate adopts the quality materials, which have reduced the wearing consumption and expand the service life .

  4)Installation on the open air environment can save the investment cost.

Reliable function

  1)Automatic control system realize the remote control and the convenient operation.

  2)By inspecting the oil cylinder and turning over the can flexible arm ensure the convenient change of the roller sheet and the plate, which have reduced the down-time lost.

  3)The whole seal system and the woring under the negative encironment ensure the clean environment with no dust leaking.

  4)Low vibration and noise.

Main Structure

Vertical Roller Mill's main structures are including the classifier, roller, plate, pressure, reducer, motor, shell equipement and so on.The seperator is a kind of high-efficient and energy-saving equipement .And the roller is a kind of spare parts used to grind and crush the materials .The plate is installed on the output axis of the reducer, which is the place the materials is crushed by the roller.And the pressure equipment is a kind of spare parts providing the pressure to the grinding roller, thus crushing the materials.
