To increase productivity and to select different grains, MEC crushers can also be supplied as complete lines, generally composed of hopper conveyor belt, STARK crusher and/or a CRUNCH hammer mill, conveyor belt and vibrating screen.
The use of screens enables the sorting of up to four particulate sizes. The crushing line can be configured to the custom requirements of the application.
All the machines proposed by MEC are characterized by a sturdy structure, which allows the minimization of vibrations during the crushing process.
Ideal for secondary crushing, the CRUNCH hammer mill is a horizontal axis machine provided with rotating hammers. It is characterised by the high degree of size reduction obtained in the fragmentation of natural stone, concrete and aggregates of low and medium hardness.
Unlike STARK jaw crushers, CRUNCH is appreciated for its ability to reduce the aggregate to a very finely ground product.
The hammers are made entirely of wear-resistant Hardox material and their position can be easily adjusted to optimize consumption.
The material is loaded through the upper feed opening (by hand or by conveyor). Hammer speed is such that the material is crushed until it is reduced to a size sufficient to pass through the grid below. The finished product falls through the hopper mounted on the lower part of the mill and is dispensed into a suitable collection container.
STARK jaw crushers are ideal for crushing not only waste marble, granite and natural stone, but also a wide variety of different materials such as agglomerate, ceramic, glass, and concrete.
Characterized by a heavy and sturdy structure, they are able to produce different grain sizes depending on the opening of the jaws.
Use of the final product has many applications: from the simple reduction of waste volume, through road construction to landscaping and manufacture of new products.
STARK crushers can also be configured in a complete crushing plant including conveyors and screens, in order to increase productivity and to select different aggregate sizes.
Manipulators are systems that take the stone, hold it and place it correctly under the splitting blades. The manipulators can operate manually or, in some cases, be automated. They can be customized according to customer’s needs or depending on the plant in which they are contained.
Another way to move the stone is to push it. The pushers are used to push stone blocks or strips inside manual or automatic splitting plants. The only condition a pusher requires, is that the back part of the block is sawn or regular. A regular surface must be presented to the pusher otherwise the feeding to the machine does not take place correctly.
The most obvious means of moving material is by using conveyors. Conveyors move stone quickly, reduce fatigue and injury as well as coming in different varieties and sizes. MEC builds conveyors to enable their customers to get the best performance from MEC equipment and systems. Whether sold as stand alone or as part of a system all conveyor belts can be operated manually or be automated.
Every model of FAST machine has an option with applying of horizontal blade at the end of vertical blades or in the middle of them in order to produce corner pieces in a single run.
The advantage of the optional horizontal blade from MEC is the ability of cutting of the corner pieces with up to 20 cm of depth in a single run, with a significant time saving and consequent increase in productivity.
This saw is appropriate for those companies requiring the highest level of production output. 5 in-line blades, operating with adjustable step cut, guarantees a very high production yield. Like the other saws, the Fast 5 accommodates all kinds of stone and is highly customizable, depending on customer needs.
The presence of a pusher bar allows to the operator to load the pieces of stone with different thicknesses up to 4 ¾”. These different size stones can be loaded one after another, without having to do any thickness sorting. Feeding this machine is fast and simple.
The FAST 3 is a thin veneer cutting machine equipped with two diamond in-line blades, with the ability to accommodate blades of different diameter on the same spindle. It is ideal for those who have the continuous production requirement and for those who need to obtain multiple-products or process different materials. The throughput capacity of the Fast 3 is about 30% higher than on the Fast 2 with two blades.
The presence of a pusher bar allows to the operator to load the pieces of stone with different thicknesses up to 4 ¾”. These different size stones can be loaded one after another, without having to do any thickness sorting. Feeding this machine is fast and simple.
The FAST 2 is a thin veneer cutting machine equipped with two diamond in-line blades, with the ability to accommodate blades of different diameter on the same spindle. Fast 2 is ideal for those who have continuous production requirements and for those who need to obtain multiple-products or process different materials.
The presence of a pusher bar allows to the operator to load the pieces of stone with different thicknesses up to 4 ¾”. These different size stones can be loaded one after another, without having to do any thickness sorting. Feeding this machine is fast and simple. In addition to the version with complete electronic operation system, Mec also offers a model with electro-mechanical Handling.
The Fast 1 is a thin veneer cutting machine for irregular stone shapes, equipped with one blade. This saw is ideal for the customers who are just getting into veneer production, or who only require minimum levels of production. Ease, speed and flexibility are the main features of this machine. Fast 1 is ideal for cutting river stones and rocks, which are mostly irregular with rounded surfaces, thanks to the presence of only one blade with single cutting step.
The presence of a pusher bar allows to the operator to load the pieces of stone with different thicknesses up to 4 ¾”. These different size stones can be loaded one after another, without having to do any thickness sorting. Feeding this machine is fast and simple.
Within the range of Pitching Machines, we also included the MEC Beaver, an automatic machine that allows creation of split face on edge. Just like a beaver, in fact, this machine “eats”, i.e. peels/pitches the sides of slabs, covers or steps giving them a rustic effect, once laid. This is a specific work, which is still currently carried out by hand by the operators in most stone processing plants.
Mec wants to offer its customers an automatic and efficient system to increase the production of this specific product.
It’s enough that the operator loads the slabs with the edge to peel/pitch towards the splitting head, the feeding and the splitting operations are completely automatic. Then just remove the pitched piece and repeat the operation on the next edge to “eat”.
The Horizontal T2, is a two head machine that pitches both sides of natural stone slabs in one single step, in order to obtain thin veneer products and wall claddings with one face split side in view.
This small plant, with automatic feeding and splitting cycle, allows to split different kind of stones, such as sandstone, marble, granite, quartzite and even concrete. Thanks to the presence of the two splitting heads you can reach a production of 16’ to 19’ per minute with the piece pitched on both sides.
The Horizontal T1 is a single head machine that, peels, i.e. pitches, natural stone pieces for the production of thin veneer and wall claddings with one face split side in view. The Horizontal T1 can pitch different kind of stones: starting from the softest, such as sandstone and marble, to the hardest ones, such as granite and quartzite and even concrete.
This small plant, with automatic feeding and splitting cycle, allows production of 13’ to 19’ per minute with the piece pitched on one side.
The machine can also be supplied complete with a return conveyor belt which brings back the piece pitched on one side to the operator. In this way it’s easier for him to load the same piece to process it on the other side.
The Pitching One is a small automatic plant for finishing the edges of blocks. It is ideal for those who need high volume and consistent productivity. This small machine is equipped with 4 rotating heads, two with vertical action and two with horizontal action.
These specific rotating heads refine the edges of a split block, always obtaining a rounded effect.
The finishing cycle is continuous, in this way the pieces are processed one after the other. The features which distinguish the Pitching One to the Pitching Side is the complete automatic mode both in the movement and in the processing.
The Pitching Side is a machine with a closed and vertical structure equipped with 4 fixed blades that finish the edges of a split block, creating a rounded effect on the split face. This finishing is very sought after by architects and designers.
The operation is extremely simple: the operator loads one stone or concrete block at a time on the work bench and, through the control panel, starts the splitting cycle, the machine handles the rest.
This machine is adjusted and operated manually but the splitting cycle is completely automatic.
