Machines in which grinding wheels are fitted and grinding is done, such machines are   called grinding machines . On the basis of their function, they can be divided into two parts. Ordinary grinding machines are widely used. These are called rough or snagging grinders. The following types of grinders are included in this category. Following are the types of  grinding machines : 1. Bench Grinder These types of grinding machines are fixed on a workbench or table. Gear or pulley is fitted in it. For rotating the big-size gears or pulley a handle is also fixed. It contains one or two grinding wheels. Edges of cutting tools can be made with this grinder. Provision can be made to operate these with power also. 2. Hand Grinder This grinder is also fixed on the workbench or table. There is a provision of moving the grinding wheels with a level as shown in the figure. 3. Pedestal Grinder Types of Grinding Machines – Pedestal Grinder These types of grinding machines are operated with e...

    Self drilling anchors   are special type of rod anchors. Self-drilling anchor consists of a sacrificial drill bit, hollow steel bar of the appropriate outer and inner diameter and coupling nuts. The anchor body is made of a hollow steel tube with an outer round thread. Steel tube has the sacrificial drill bit at one end and the corresponding nut with a steel end plate. Self drilling anchors are used in a way that hollow steel bar (rod) has a corresponding sacrificial drill bit on its top instead of a classic drill bit. Centralisers guarantee a consistent grout cover around the hollow steel bar and that the bar remains in the center of the drilled hole. Construction of self drilling anchor Anchor hollow steel bars are produced in sections with standard lengths of 2.0, 3.0 or 4.0 m. The standard outer diameter of the hollow steel bars ranges from 30.0 mm to 127.0 mm. If necessary, hollow steel bars are continued with coupling nuts. Different types of sacrificial drill b...

  Polymeric aluminium chloride  (PAC) is one of the most effective water treatment chemicals in use today. It is widely used for drinking water and wastewater treatment because it offers high coagulation efficiency and the widest range of pH and temperature applications compared to other water treatment chemicals. This high efficiency increases plant capacity and reduces operating costs.   PAC has a very low impact on pH, thus minimising the need for pH regulating chemicals, which further reduces operating costs. PAC is used in the paper industry to improve drainage rates in neutral and alkaline processes, as a retention aid to improve sizing efficiency and to reduce cation requirements.   Uses for PAC: coagulant, water treatment chemical and deodorant ingredient PAC is one of the most effective water treatment chemicals we know today, enhancing flocculation and coagulation even at low temperatures - promoting the agglomeration of fine particles.  PAC  remo...

Wearing a  Workwear Suit  has its benefits. Uniforms can build team unity and maintain a professional image, but what if that image starts to feel too similar among colleagues? It is important that employees share their own unique style when wearing workwear. It is easy for clients to pick out employees when wearing uniforms in the workplace. However, it's also easy for employees to feel lost in a sea of blue company polo shirts. Employees and colleagues want to feel different. You can't dress up a uniform without first establishing a polished, professional look. From there, you can show off your personal style by wearing personalised accessories, jewellery or coloured or fun socks. You can even take the professional look up a notch by adding some style. It all depends on the individual and what the company allows. Choosing the right uniform Think of the  right uniform  as a blank canvas for employees to create their own unique look. However, an ill-fitting uniform, ...

    Non-sparking tools   are made from copper-based alloys such as copper-titanium alloys, copper-nickel alloys, copper-aluminium alloys (or aluminium bronze), bronze or brass. Tools made from these materials are softer than traditional steel tools because they are made from non-ferrous metals (mainly copper). However, they have an advantage that no other tool can match, namely that they produce a cold spark with almost no heat and therefore do not ignite any flammable materials present in the environment.   Why are Non Sparking tools sometimes referred to as Non magnetic? Non-sparking tools are sometimes referred to as  non-magnetic  because they allow magnetic fields to pass through them without being affected by them. Copper titanium and copper beryllium allow a full magnetic field to pass through them and can be classed as non-magnetic. However, aluminium bronze contains two metals, iron and nickel, both of which are magnetic and therefore only copper t...
