Select the nip roll nip determined by volume and the density level of the cake, the roll press working process, if large particles or individual encounters super lump, the

roller press with a bag-shaped accumulator , the instantaneous floating roller can move through it, to protect the roller surface is not broken

Bad and found the roll surface damage (spalling, potholes, etc.), can be used to repair welding method, after welding to ensure its concentricity 1396 ± 41mm, shaft diameter

1398 ± 2mm, roll width 1050 ± 2mm, are not allowed to have pores , slag, cracks and other defects, surface hardness to reach HRC62-65. nip

The choice also with the feed end of the sliding gate width adjustment related material gate adjust the size of the column section, thereby affecting the cake thickness and

yield, ram adjustment request is equal adjusted so that the material does not feed roller press nip off the centerline, ram adjustment is driven by the motor, roller

Press near the manual control button to adjust the quick and easy.

Factors affecting production mill a material impact mill grindability of the main factors is the ability of the material grindability grindability of materials refers to the

ease of the material to be grinding, grindability of materials and material properties about. Materials by roll after size reduction, grindability get

Improvement of the system yields improved. Dongchu poor clinker grindability of cement clinker production is low, good grindability of clinker grindability poor clinker with the

use of Dongchu just produced clinker and clinker mixed use, so as not to make the cement production is too low, both to ensure

Cement production but also to ensure that the indicators of cement grinding qualified.



System problems and improvement measures for system startup drive process improvement program through the system to open the vehicle's many improvements, making the system

start-up time from the initial production debugging nearly an hour when the time is shortened to about 15min now greatly shorten the mill when idling

Room, reducing the impact of the ball on the liner wear, ball wear and cement their over-grinding phenomenon, saving power consumption.



Cement conveying system transformation is used when the original design of pneumatic conveying, the use of the actual production is not very good, such as the failure rate of   crushing equipment

the pump, bearing seals often damaged, resulting in burning the bearing, the high cost of the vane, the wear , fuel consumption and other shortcomings. Use workshop

Overhaul of the time on the transport system has been modified from the original to the current pneumatic conveying bucket, air chute conveyor. After the transformation,

reducing the dust concentration, reducing the failure rate, and significantly reduces the amount of equipment maintenance, improved working environment of employees, the system

Power consumption is reduced, thus saving the cost of production.  feeder breaker
