· Image: Loader. A loader is a heavy equipment machine used in construction to move aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled material, rock, sand, woodchips, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car).
· ACIDS The acid used is a sulfonate organic acid (methanesulphonic and similar), in water solution, chloride-free. There are four different types of acid (medium, weak and very weak): the choice of an acid is essentially conditioned by the sand temperature (in summer a weak acid is preferable, in winter a stronger one), but also by the type of sand, of resin and by the required hardening speed.

· In most cases sand moulds are made by specially designed moulding machines. Various moulding methods differ in following aspects: 1) Type of flask required, 2) Method of packing the sand with in the flask, Whether mechanical assistance is provided to turn or handle the mould.
A few different types of patterns may be used in the sand casting process. Solid Pattern: This is a one piece pattern representing the geometry of the casting. It is an easy pattern to manufacture, but determining the parting line between cope and drag is more difficult for the foundry worker.
Moulding Tools. 1. Moulding Sand: Green sand is an aggregate of sand, bentonite clay, pulverized coal and water. Its principal use is in making molds for metal casting. The largest portion of the aggregate is always sand, which can be either silica or olivine.
This sand is accumulated on the floor after casting and hence also known as floor sand. 7. System Sand: The sand employed in mechanical heavy castings and has high strength, permeability and refractoriness, is known as system sand. It is used for machine moulding to fill the whole flask. In machine moulding no facing sand is used.
· The most common type of core is a dry sand core. The basic process for making a dry sand core is by packing sand into a core box (essentially a mold) and then hardening it. The core is then supported in a mold by means of core prints or chaplets and the molten metal is poured into the mold, creating the desired iron casting.
sand or water to produce "sand-struck" or "water-struck" brick. Brick may be produced in this manner by machine or by hand. Dry-Press Process - This process is particularly suited to clays of very low plasticity. Clay is mixed with a minimal amount of water (up to 10 percent), then pressed into steel molds under pressures from 500 to
There are two main types – the palm sander and the orbital sander, both used by hand. The palm sander is square in shape and operates on a belt model. The grit paper is attached to the belt and sands the wood surface with forward motion. Palm sanders are typically used to sand hardwood floors and square areas by applying a back and forth pattern.
