Ray Bradbury’s “The Concrete Mixer,” tells the story of a Martian named Ettil, who refuses to invade Earth on the theory that the people of Earth have greater morale than the people of Mars. Ettil had feared that his people were doomed to the same fate as the people in his books: whom at the end of every story were conquered by Earth. When the Martians’ arrive to Earth nothing is as any of them thought it would be. They had been anticipating a great battle but instead the Earth people met with friendly faces and open arms. Ettil walks around Earth paranoid, and confused by the people of Earth’s hospitality. Ettil finds himself more frightened by the human’s amicable attitude, than he was when he thought they were going to battle. “War is a bad thing, but peace can be a living horror” (233)…
First, the ball mill anti-blocking, leak-proof basic knowledge:The anti-blocking, we first need to check the sizes of materials and material feeding amount, if the delivery volume overload, can also cause the clogging of import.For the proof, we first check whether the imported seal wear, after a period of time will have leaked, we should timely replacement of packing seal.And we have the entrance position design discharge funnel and pipes, can be timely will leak slurry discharged into the trench.Second, wet ball mill liquid pump speed adjustment:Through debugging during night cyclone station pressure test, to replace the slurry pump belt pulley.In third, ball mill imports and exports effects of abrasive material size:Ball mill control into the limestone particle size, in the scope of design.General wet ball mill feed size of 80% particles of less than 12mm.Regulation of entrance feed mill.General to reduce electricity consumption, mill should be routinely maintained in rated operation conditions, but sometimes as a result of a variety of reasons, the steel ball added is not timely, then according to the ball mill main motor current to reduce properly reduce the feeding quantity, to ensure the qualified pulp particle size.In fourth, the ratio of ball mill to adjust grinding material size:To maintain a reasonable ball loading and the steel ratio.Limestone is on impact, extrusion…
(2) Since the water content of all kinds of raw materials is different, when making up materials with the weight method, after the materials are matched up with a certain weight proportion, they seemingly satisfy the assortment requirement, but as a matter of fact, the water is also seen as raw materials. For this reason mobile concrete mix plant, even on the normal condition, the chemical component of the materials that are produced by the grinding mill cannot reach the stipulated requirement. And what is more js concrete mixer, since the raw material homogenization storeroom is mixed with the air, if the water content of the raw materials exceeds 1%, raw material homogenization will not be realized.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:cement batch plant,Twin Shaft Concrete Mixer,We will provide you with the best product and service. In addition, due to the differences of the easy-wearing parameters of all kinds of materials, the flow speed of the materials inside the mill, so that the materials that is easy to be ground such as clay and coal will be firstly discharged out of the mill and the materials that is not easy to be ground such as limestone and iron raw materials will be remained inside the mill, as a result of which, the water fluctuation and saturation factors of the materials that are discharged out of the mill is sometimes high and sometimes low. Especially when too many materials stick on the mill, the mill will be easily saturated. If the mill is run without anything in it, since the limestone that sticks on the mill is discharged continuously, the KH value of the discharged materials will increase dramatically.(2) Since the water content of all kinds of raw materials is different, when making up materials with the weight method, after the materials are matched up with a…

The safety design of the control flow is the control of every aspect of contact with the control of the upper and lower links. For example, before feeding the mixer, first determine the mixer open whether? The mixer doors are closed no? Mixer clinker emptied no? All this with the material with a good no? System as long as a condition does not meet or did not complete the next step to stop the work, and prompted a major problem even alarm.
