Raymond mill in the course of this malfunction ‚ according to the following processing : Raymond mill is a common fault : no less powder or flour production is low . Causes: ( 1 ) Locks powder is not adjusted‚ Mifengbuyan ‚ resulting powder suck . ( 2 ) blade wear and material shovel can not afford . Remedy: ( 1 ) checking and adjusting locks sealed powder was found to be leaking at the blade . ( 2 ) Replace the blade . Raymond Mill Troubleshooting II : refined powder too thick or too thin

Cross Linking effects on Polymers Purpose To observe the properties of the polymers with different amount of borax to see the effects of cross linking. Question How does the amount of a cross linking substances affect physical properties of a polymer Experimental Design A polymer was made with precise measuring of all the reactants especially different measurements of Borax solution as it was the key to cross linking. Physical properties of all the polymers were observed and the role of

Task 1 Foundry Work Sand casting involves many sequences and there are as follows: - Design and manufacturing the casting. When doing this all vertical edges must be tapered as to make it easier to lift the pattern out of the mould. - Contraction allowances have to be added to the pattern because it shrinks in size in all dimensions. In this case it’s Aluminium‚ which has a contraction allowance of 1.3%. - Machining allowance: Castings are usually machined so that they fit perfectly with

The goal of this experiment is to find the molar mass of an unknown substance by measuring the freezing point depression of a known amount in an aqueous solution. Freezing point depression is a colligative property of solutions. There are three other properties‚ which are boiling point elevation‚ vapor pressure depression‚ and osmotic pressure. Colligative properties of a solution depend on the amount of solute and solvent molecules and not the specific properties of the molecules. The temperature

4.11 The Design of the Cold Slug Wells The cold material well is located on the movable template opposite to the main flow path or at the end of the runner to trap the cooler advancing front of the melt while allowing hot material to flow into the cavities. The cold well should be slightly larger diameter than the main channel. To pull the sprue out of the sprue bush it has a snatch or pull pin or sucker pin underneath. Ejector pin system can be designed in three different methods: however the undercut

Different Components of Diesel oil boiler for Power Station Diesel oil steam boiler set there are many other auxiliaries attached to at diesel power station. Diesel power station Fuel Supply System In fuel supply system there are one storage tank‚ where oil in stored. Strainer : This oil then pump to dry tank‚ by means of transfer pump. During transferring from main tank to smaller dry tank‚ the oil passes through strainer to remove solid impurities. From dry tank to main tank‚ there is another

To Test Charles’ Law and estimate Absolute Zero In this IB Lab you will be assessed on the following criterion Conclusions and Evaluation Aim: Physics has many hundreds of laws and these can be tested in experiments to see if they are true. In 1787 the French scientist‚ J.A.C. Charles‚ published a law connecting the volume and temperature of gases. Your task is to see if you agree with his law. Another thing you have to consider is “ is my experiment accurate enough to prove or disprove the
