Problems solved by technology

Carbon arc gouging is also prone to carburization
At the same time, carbon arc gouging consumes more carbon rods, and the cost is higher, which is not conducive to saving resources.
If plasma gouging is used, during the process of plasma gouging cement rollers, plasma gouging is greatly affected by gas flow, arc length, current size, and cutting speed, which is prone to arc breaking and energy waste.

Embodiment Construction

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.

[0017] A method for repairing a grinding roller of a roller press comprises the following steps:

[0018] Step S001, erecting both ends of the grinding roller horizontally on the rotating device, so that the rotating device drives the grinding roller to rotate;

[0019] Step S002, aiming the nozzle of the plasma gouging machine installed on the first moving mechanism at the grinding roller, the nozzle of the plasma gouging machine is located at the first end of the grinding roller, and the nozzle is set downward, and the spraying dire...

Abstract

The invention provides a method for repairing a grinding roll of a cement roller press. Through operation parameters set in the method for repairing the grinding roll of the cement roller press, the phenonmeon that occurrence of arc breaking can be reduced to the maximum extent in a gas gouging process of a plasma gas gouging machine can be ensured, and the working efficiency is promoted; meanwhile, less noise, smog and dust are produced, a site working environment of operators is optimized, and atmosphere pollution is reduced. Meanwhile, in the method for repairing the grinding roll of the cement roller press, a distance detection device and an arc ignition module are additionally arranged, so that waste produced by enabling the plasma gas gouging machine to encounter pits can be reduced,and due to the pits of the grinding roll, the breaking of arc on the plasma gas gouging machine is easily carried out; and moreover, due to cooperation of the distance detection device and the arc ignition module, the plasma gas gouging machine returns to work in time when the breaking of arc on the plasma gas gouging machine occurs, so that the gas gouging progress and the gas gouging quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a method for repairing a grinding roller of a cement roller press. Background technique [0002] The roller press is designed according to the principle of material bed grinding, and its main features are: high pressure, full speed, full material, material bed crushing. The roller press consists of two extrusion rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. The material is fed from the top of the two rollers, and is continuously brought into the gap between the rollers by the extrusion roller. After being subjected to a high pressure of 100~150MPa, it becomes a dense cake and is discharged from the bottom of the machine. The discharged material cake contains a certain proportion of fine-grained finished products. In the interior of the non-finished particles, a large number of cracks are generated, ...
