Roller for Roller Press

Our company can provide various types of rollers in line with different roll squeezers. It has been widely applied in grinding industry and is fit for mill. Applicable for the cement processing industry; it can be installed before the ball mill as pre-milling equipment or consist of mixing grinding system with ball mill . The hard surface welding technology can service a roller welding service life to long. -The press roller surface adopts hard alloy stud setting-in structure to increase the life time of the roller sleeve -Multi-layer welding enables long running times without stoppages. -The complete hard face welded surface is used for feed material of normal wear characteristic. Surface repair can be carried out quickly.

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.

The support rollers are mounted on a massive cast iron or steel base plate which provides the inward horizontal forces on the rollers and distributes the weight of the kiln over the pier. The spacing between the support rollers has to be small enough to prevent large horizontal forces, but large enough to keep the kiln laterally stable. Rollers are designed to subtend 60° at the Rotary kiln tyre center, and this seems always to have been the case.

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.

Cement Industry utilizes Fixed Inlet Grate technology to optimal distribution of clinker. Purpose of using the fixed inlet grate: - Optimal distribution of the clinker. - Enhance heat flow, the intense heat from process will be used to increase secondary air temp and tertiary air temp that will optimize kiln operation efficiency. - Reduce maintenance cost. Advantage of CTI’s Grate plate - CTI’s Grate plate with non dust leakage - High velocity air-jet beam - Even less of air flow, dust will not dropdown - Strong grate blade and long life time
