Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.
Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.
Moisture Control in Concrete Production | Agg-Net
There are various factors that will affect the slump test, including ratios of the aggregates and admixtures, and also moisture content. This article describes how the addition of digital microwave moisture measurement into the concrete plant can help produce consistent concrete batch after batch and, therefore, consistent slump properties.

WHAT IS VOLUME BATCHING OF CONCRETE AND HOW IT IS
What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching. Below are mentioned some of important points to remember before adopting volume batching method in …
The Details of a Concrete Delivery Ticket
The ticket also tells the batch time, which is important for predicting slump loss and setting time, and there is a lot of important cost information that will help you figure out what the concrete is worth (if you are delivering it) or how much you will have to pay (if you are receiving it).
Concrete: The Basic Mix
"rodding" the concrete inside the mold with a thin spatula. Special chemicals called "water reducing agents" are used to improve workability at low water to cement ratios and thus produce higher strengths. Most ready-mix companies use these chemicals, which are known commercially as superplasticizers.

Water-to-Cement Ratio and Aggregate Moisture Corrections
The lower of the two w/c ratios should be used for the mix design. The water-to-cement ratio is the weight of water provided in a mix divided by the weight of cementitious materials. The total weight of water includes all batch water and free water from the surface of aggregates.

concrete, plaster & mortar mixes for builders
High-strength concrete suitable for: precast concrete, heavy-duty floors To make 1 cubic metre of concrete you will need: 9,2 bags cement + 0,60 cubic metres sand + 0,60 cubic metres stone. 1.2 small batches: use containers such as buckets, drums or tins. Use the same size of container for measuring all the materials in a batch.
Work the concrete into the corners and along the edges with a spade or trowel. To ensure that a dense concrete is achieved, remove all entrapped air by compacting concrete using iron rods or spades. To avoid cold joints, ensure that the curing period between each batch does not exceed one hour. Curing

In making concrete in this example, we will call this volume (143 liters) a ''batch'' of mixed concrete. If you start with a different volume of cement as ''1 part'' or use a different ratio of components, then the size of the batch will be different, but the procedure for calculating the end volume of concrete will be the same; the sum of the parts in liters (or cubic feet) times 2/3.
