Sand making machine, also known as sand maker, is a kind of important fine processing equipment in mine machinery equipment. Compared with traditional sand making machine this machine, has more application fields, the material processing range, large processing quantity, durable, and can ensure the continuous production of a series of advantages. 

The device on both sides of the bar to increase the discharge counter board, with multiple crushing material function, make the material grinding, extrusion, collision in the crushing cavity, sand production rate is high, and with a shaping effect, the sand particle type is more uniform, particle size also equipped with adjusting device can control the sand convenient.

At present, the sand making machine on the market are widely used in mechanism of sand stone, cement, refractories, metallurgy and other industries. sand making machine is based on the absorption of the essence of industry technology, product improvement and optimization of the original sand making machine. The equipment has been constantly upgrading, various performance have reached the advanced level of sand industry. 

Sand making machine is currently the most advanced, adds a counterweight wheel, increases the kinetic energy, increase the counterattack plate adjustment device and so on, so that the adjustment of discharging fineness is more convenient, without opening the shell, can adjust, by saving the trouble of crane.

The production of vertical roller mill is inseparable from the screeb and other equipment, these different equipment to assist the material production process, their role in the work of different, but leave any one machine, can not successfully complete the material Production, so for the failure in production to be timely processing, here to analyze the vibration of the side plate cracking how to deal with the problem.

Vertical roller mill is an important auxiliary equipment in the production of vertical roller mill. Its existence plays an important role in material grinding. If the equipment fails during working, it will cause a great deal of production Impact, so we have to promptly solve its problems, one of the common phenomenon is the phenomenon of cracking the side panels, this phenomenon how to solve it?

1) First check whether the hexagonal bolt connection in the crack area is reliable. Remove the riveted bolts on both sides of the side plate and the upper stiffener to check for damage between the angle plate and the mating face on the plate. In the case of qualified surface to ensure that both sides of the crack plate alignment, the production conditions to ensure that the screeb to make better to help vertical roller mill production process;

2) Grind a bevel along the entire length of the crack center (inside the sieve) along the crack perpendicular to the direction of the frit. The welding torch can not be swung. It can be welded in 2 stages and be struck with a needle gun after each weld to eliminate Stress and welding slag, continuous vertical welding, each seam with a needle gun hit, until the welding is completed, you can handle the way to be able to better solve the production of vertical roller mill, screeb cracks caused by the impact on production;
