Skull Crushers

Skull crushers are an excellent movement for bringing up your triceps, but as the name implies there is a chance of injury when doing this move. They hit the triceps from a unique angle, which stimulates growth, so they should be a staple in your arm routine. Follow these directions to get this move right, and develop your triceps without actually crushing your skull!
Lie on a flat bench with a barbell across your chest. Grab the bar with a shoulder width grip and press it straight upwards, as if you were doing a bench press.
Keeping your upper arms perpendicular to your body, bend your elbow and lower the weight towards your head. DO NOT DROP THE WEIGHT ON YOUR HEAD! Although this movement is called a skull crusher, do not actually crush your skull!
Stop the weight when your elbow is bent at a right angle. From this point move the weight back up to the starting position. Do not allow your upper arms to sway, or you will be using momentum, and not your muscles, to move the weight.
Do this move whenever you work your triceps. If you work triceps and chest on the same day, as with a push/pull/legs split, do this move after you do your compound chest work. That is, do this move after you bench press. If you do this before you bench press, you will wear your triceps out prematurely and this will reduce the amount of weight you can lift with your bench press.

Jaw Crusher Liners


If you are in an industry that uses them, then you no doubt understand the important nature of jaw crushers, and of the liners that are used with them. It's very important that an eye be kept on the crusher liners to ensure that they last for the longest amount of time possible.
So what can you do to make sure that you have the right liner for the right job? Well there are many, and the choice as to which one to use is totally up to you. Here's some of the type of jaw crusher liners with their advantages and disadvantages.
On the basis of Shape
Straight Jaw Crusher Liners
This type of jaw crusher die/liner has a lot of advantages, but overall they just don't last very long especially with smaller CSS (Closed Side Setting) settings. You'll find out that they wear out in just a short time. This is due to its poor wear distribution. They may even plug up frequently. But, they have the maximum feed opening, most effective nip angle, and the greatest reduction ratios. These crusher liners will suit your needs if you are running a small operation, but won't cut it if you have a full blow production facility going on.
Half-Belly Jaw Crusher Liners
These crusher dies/liners essentially are straight with a curved end. When it comes to wear distribution, they are better than the straight dies but have poor reduction ratios than the later. They have fewer issues of plugging but a disadvantage of smaller feed opening than the straight ones. These jaw crusher liners prove very useful when the feed material has a significant quantity of fines, that the bottom of the liner would wear off rapidly.
Full-Belly Jaw Crusher Liners
This particular jaw crusher liner is exactly the way it sounds, being a fully curved variant. Owing to the best wear distribution of all the three types of crusher liners, these liners will last the longest. They don't plug quite as bad, provide a decent looking product, and are capable of being used with smaller CSS settings without sustaining much wear on the ends of the die. However, due to its shape, jaw crusher loses the effective nip angle in the upper portion of the crushing box.
As they reduce the feed opening, these jaw dies are particularly used when the crusher is larger than required for the feed size being fed. With these jaw crusher liners, the largest feed size won't exceed the gap between the jaw dies just above the center of the dies in the horizontal direction.
On the basis of Surface
Flat Surfaced Jaw Crusher Liners
This type of crusher die/liner has a flat surface which exerts an even and flat pressure on the material being crushed. If you use a flat liner, you may discover that within a pulverizing material the pressure becomes even and flat, giving the rock absolutely nowhere to go. A flat liner has no way of gripping a rock, which is the area in which a corrugated die excels.
Corrugated Jaw Crusher Liners
Unlike Flat Liners, theses crusher dies/liners have a corrugated surface. It is a common sense that the ridges in a corrugated die will be able to produce a more concentrated force which enables to break rock with less effort, meaning that power requirements are extremely low. With lower power requirements, the crusher has less load to contend with. But these corrugated dies don't come without their own issues. They can be easily plugged and the feed opening can be reduced.
This piece of equipment is robust but isn't something that you can take for granted. You need to take care of it, keep an eye on it, and make sure that both you and your employees are using it as intended.

Aluminum Cans

When you recycle aluminum cans, it is not required they be crushed first. The main reason you might want to crush aluminum cans is they will take up less space. You will be able to fit more aluminum cans into a bag once they have been crushed. If you have middle school age boys, they will love spending their time stepping on cans to crush them for you. Not all of you are so lucky, however you will be happy to know aluminum can crushers are on the market and their cost is reasonable.
You will find a number of can crushers to choose from. Depending on your needs you can choose a single can crusher, a multi-can crusher or a garbage can crusher. You can even get the Easy Pull Can Crusher, which works alone or it attached to a collection bin. The collection bin looks very much like a large 30-gallon trash can. The can crushers range in price from $9.99 to $29.95. You can find them at Target, and many hardware stores. You can purchase them online also.
Can crushers are made from a very sturdy construction, which can crush all standard 12 oz. Or 16 oz can to about 1-inch. Can crushers can be used in garages, basements, pantries, cabins, dorms, campers, schools, and much more. Just about anywhere you need a can crusher you can use one. They are very simple and easy to use. They will help you save space while you are doing your part for the environment. Not to mention the extra money sell the aluminum will bring you. At one time the price per pound for cans was about $.60. It may not sound like much, but it adds up quicker than you might think. If you buy coke or Pepsi products for your home in 12 ct. or 24 ct. cans, you will find you can amass a good size number in a short amount of time, especially if you have help drinking some of those.
Recycling cans is one of the easiest things to do. It is reported Americans throw away enough aluminum cans to rebuild all of our commercial planes. It sounds like a lot because it is. By recycling our aluminum cans we can conserve enough energy to run a 100-watt light bulb for 4 hours or a television for 3 hours. Recycling aluminum cans also saves 95% of the energy needed to make new aluminum cans. Recycling also creates 95% less air pollution and 93% less water pollution than making new aluminum cans. The great aspect of aluminum is it can be recycled over and over again and the end product will always be the same. In fact it only takes 60 days for a can to be recycled and end up back on the shelf with more soda for you to purchase again. So by crushing them with a can crusher you will save yourself space, and by recycling them you will provide the earth with a much need favor environmentally.

In any busy auto shop, old oil filters can pile up on you in a hurry and become a disposal nightmare. An oil filter crusher can save you time and money by reducing them down to manageable size and helping you to dispose of them legally and properly. If the EPA investigates and find you are not disposing of your oil filters properly you could be fined a lot of money. If you are outsourcing your oil filter disposal to another company, the EPA can still come after you if they are not disposing of them correctly and legally. The best solution is to do it yourself with the right equipment.
Used oil filters are filled with old oil and sludge and are classified as hazardous waste by the EPA. The used oil is trapped in the filter with an anti-backflow valve that prevents the oil from flowing out. So trying to shake the old oil out or letting sit upside down on a drain will not do you any good. Only the shear force of an oil filter crusher can remove all the material too the satisfaction of the EPA. The force used to crush the filter pushes 95% of the oil and sludge from the filter. This process leaves you scrap metal that can be sold to scrap yard.
At Red Hill Supply, we carry the John Dow DOWAFC100-94 oil filter crusher. This unit requires 85 psi of shop air and has a powerful hydraulic system for crushing automotive filters. (There is a larger unit for bigger filters). JohnDow Industries has been in the automotive aftermarket business for over 20 years and they serve mainly service bay operations. They offer everything from used oil systems to vehicle exhaust products. The hydraulic system in this unit is manufactured by SPX OTC.
