Rocker arm is one of the major components vertical grinding machine, The rocker device is mainly composed of upper rocker, down rocker, rocker arm shaft, bearing, bearing seat etc. The upper rocker arm used to install the roller, the down rocker arm connects with hydraulic system. Two rocker arms are connected into a whole by shaft and taper sleeve and taper pin. Features of our rocker arm: 1. Duarable; 2. Excellent tensial strength; 3. Accure level of tolerance; 4. Good dimensional accuracy; 5. Superb surface finishing; 6. Easy to use and install.

Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles. Vertical raw mills are widely used in the concrete and mining fields, and are also used to process gypsum. Up to six stationary grinding rollers roll on a rotating grinding table. The material is drawn in between the rollers and grinding table and ground by pressure and shear. The required pressure forces are produced by a lever system comprising, among others, a roller arm, along with a hydro pneumatic tension system. After being rolled over by the rollers, the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table. Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it is separated by the rotating wheel (rotor) into grits and fines. The grits fall back into the grinding zone whereas the fines leave the classifier with the gas flow for being separated in cyclones or a filter. Grinding roller is core part of vertical mill. - Grinding rollers produced by Great Wall Steel Casting have features of high hardness, good anti-cracking and strong wear-resistant capability. - During grinding roller production, technicians carry out finishing processing with arc air gouging, which can guarantee outlook quality of steel castings.
