Barite Grinding Mill grinding roller maintenance

The Barite Grinding Mill is a widely used fine crusher equipment product. It is also an important task for the maintenance and repair of wearing parts during the use process. But how should the Barite Grinding Mill blow head be repaired and maintained?

Barite Grinding Mill working principle

The material falls vertically from the upper part of the Barite Grinding Mill into the impeller of high-speed rotation. Under the action of high-speed centrifugal force, the material which is distributed around the impeller in another form in the form of an umbrella produces high-speed impact and pulverization. After the materials collide with each other, Between the impeller and the casing, the vortex is formed by multiple collisions, friction and pulverization, and is discharged straight from the lower part to form a closed circuit for multiple cycles, and the required size of the finished product is controlled by the screening device.

It can be seen from the working principle of the Barite Grinding Mill that the grinding roller is the main wearing part. When the impact force of the grinding roller is light to medium, it can be welded with high chromium alloy cast iron & ldquo;pre-hardened & rsquo; After the solder layer is removed, the surface of the high manganese steel grinding roller is hardened to improve wear resistance.

Barite Grinding Mill roller repair

1. Preparation before welding: 8 to 10 grinding rolls are piled up at one time, and the scale welding site strictly removes oxide scale, oil, rust and stains. Check the presence or absence of cracks on the hammer with the development test solution before welding. The mother crack needs to be grinded out by the angle grinder, and then welded with JHY-1A welding rod before welding.

2, surfacing transition layer: In order to increase the firmness of JHY-1C welding rod, first use a JHY-1A welding rod to weld a layer of transition layer, welding machine current l20 ~ 130A (use DC welding machine). 8 to 10 grinding rolls are welded one by one, do not apply continuously, cold welding, not hot. Generally, two layers are welded, and the size of the surfacing layer is 10mm. If the grinding roller has more wear, it may be welded several layers depending on the situation. In multi-layer surfacing, the welding slag should be removed between layers, and the interlayer temperature should not be too high to prevent the heat affected zone from becoming brittle. When using JHY-1A welding, use small line energy as much as possible, and use short arc, jump welding, short-segment welding, intermittent welding and other technological measures. Each weld is welded and hammered with a hammer to relieve stress.

JHY-1C, a surfacing electrode for Barite Grinding Mill grinding rolls, which is a mass-hardened austenitic hard alloy surfacing electrode with good toughness and crack resistance, thus resisting impact and high resistance. Grinding.

Through continuous trials, Shibang has invested a large amount of capital and technology in the improvement of Barite Grinding Mill grinding rolls and technology, making Barite Grinding Mills more widely used.

Four Steps Ensuring Safety And Efficiency Of Machine Preparation And Shipment

  • 1. Checking order. With the sales contract, the order tracking clerk checks the models and quantities of machine and spare parts for machine preparation.
  • 2.Quality test before delivery. Upon completion of the manufacturing of equipment, the quality inspector strictly checks quality of every machine with the checklist.
  • 3. Check items when packing. Before packaging and shipment, the order tracking clerk checks the packaged items again with the packing list to avoid loss of items.
  • 4. Packaging and transport. Professional packaging and modular solution of transportation guarantee the safe and smooth delivery.
